If you’re a frequent reader of Universe Today you know that, despite the end of the Shuttle program and the constant battle for a piece of the federal budget, NASA has a lot on their plate for future space exploration missions. But there are still a lot of people among the general public who think that the U.S. space administration is “dead,” or, at the very least, in the process of dying. Which is unfortunate because there’s actually a lot going on, both in space and in development on the ground.
The video above, released Monday by Johnson Space Center, shows highlights from 2013 as well as some of the many things NASA has in progress. As anyone can see, rumors of its death have been greatly exaggerated! (By whom I’m still not quite sure.)

What was the Universe like more than 13 billion years ago, just 500 million years after the big bang? New data from the Hubble and Spitzer space telescopes reveal some surprisingly bright galaxies that are about 10 to 20 times more luminous than anything seen previously in that epoch.
Garth Illingworth from the University of California, Santa Cruz said the discovery of these four bright galaxies came from combining the power of both telescopes, but these galaxies lie right at the limit of the telescopes’ capabilities.
“We’re actually reaching back 13.2 billion years through the life of the Universe — that’s 96% of the life of the Universe that we are looking back at these galaxies,” said Illingworth, speaking at the American Astronomical Society meeting in Washington D.C. this week. “That’s an astonishing undertaking and an astonishing accomplishment that Hubble and Spitzer have achieved.”

Illingworth said the typical galaxy candidate from that far back in time is very faint and hard to see. But these new galaxies are about 15-20 % brighter than what astronomers have seen before at redshift 10.
The tiny are bright because they are bursting with star formation activity. The brightest one is forming stars approximately 50 times faster than the Milky Way does today. Although these fledgling galaxies are only one-twentieth the size of the Milky Way, they probably contain around a billion stars crammed together.
Astronomers think these bright, young galaxies grew exceptionally fast because of interactions and mergers of smaller infant galaxies that started forming stars even earlier in the Universe. Since the ancient time billions of years ago when the light that we now see started its long journey to us, they have probably kept growing to become similar to the largest modern galaxies. Many of the stars of these infant galaxies likely live on today in the centers of giant elliptical galaxies, much larger even than our own Milky Way.

Illingworth said this era appears to be a timeframe where things were changing quite rapidly. “We’ve gone back to a very interesting time when the Universe is changing,” he said.
The galaxies were first detected with Hubble, and astronomers were able to measure their star-formation rates and sizes. But using Spitzer, the scientists were also able to measure the galaxies’ masses.
“This is the first-ever measurement of the mass density of the galaxies when the Universe was at 500 million years of age,” Illingworth said. “These galaxies are about a billion times the mass of our Sun, which is massive for those times, but still only 1% the mass of the Milky Way.”
Illingworth added that the mass measurements are rough estimates because of how challenging the task was.
Illingworth and team member Ivo Labbé from Leiden University said they are looking forward to finding out more about these galaxies, particularly from future observations with the upcoming James Webb Space Telescope.
“At the same time, the extreme masses and star formation rates are really mysterious,” Labbé said, “and we are eager to confirm them with future observations on our powerful telescopes.”

UPDATE: Orbital announced the Antares launch today (Jan. 8) has been scrubbed because of solar activity. More info on the issue and a new launch date will be forthcoming.
Update: NASA and Orbital have set Thursday, Jan. 9 as the new Antares launch date. Liftoff is targeted for 1:07 p.m. (EST) Watch the launch live, below.
WALLOPS ISLAND, VA – Launch managers gave the “GO” for launch of the private Antares/Cygnus rocket to the space station on Wednesday, Jan. 8, even as the polar vortex swept in bone chilling cold to the launch site on the Virginia shore and across much of the United States.
At a launch readiness review today (Jan. 7), managers for spacecraft builder Orbital Sciences approved the launch, pending completion of a few remaining items, said Mike Pinkston, Antares program director for Orbital, at a media briefing today.
The commercial Antares rocket is launching the Cygnus cargo spacecraft on its first operational mission bound for the International Space Station (ISS) with a huge bounty of science experiments.

There is only a 5 minute launch window that extends to 1:37 p.m.
The launch of the two stage, 133 foot tall Antares could put on a spectacular sky show.
Antares blastoff may be visible to millions of spectators up and down the US East Coast spanning from South Carolina to Massachusetts – weather permitting.
The Antares launch comes amidst the unprecedented, unrelenting and dangerous cold arctic air mass sweeping across the US.
Frigid, high winds buffeted the rocket and launch site all day today as technicians continued last minute preparations, taking care to insure safety for the rocket and themselves.
But tonight Antares and Cygnus were glistening beautifully under star lit skies during my up close visit to the launch pad.

The launch was originally scheduled for Tuesday, but was postponed a day to Wednesday because the rocket is only certified to lift off when the temperature is above 20 degrees Fahrenheit, said Frank Culberton, executive vice president and general manager of Orbital’s advanced spaceflight programs group.
Today’s temperatures at Wallops were only in the single digits and teens and felt much lower with the blustery conditions all day long.
Temperatures are expected to ‘skyrocket’ to the balmy 30’s on Wednesday.

There is a 95 percent chance of favorable weather at the time of launch, NASA said. High, thick clouds are the primary concern for a weather violation, but they are minor.
Both the Antares and Cygnus are private vehicles built by Orbital Sciences under a $1.9 Billion supply contract with NASA to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware to the ISS.

Orbital Sciences commercial competitor, SpaceX, is likewise under contract with NASA to deliver 20,000 kg of supplies to the ISS with the SpaceX Falcon 9/Dragon architecture.
Both the Orbital Sciences Antares/Cygnus and SpaceX Falcon 9/Dragon vehicles were developed from the start with seed money from NASA in a public-private partnership.
A total of eight Antares/Cygnus missions to the space station are scheduled over the next two to three years by Orbital under its Commercial Resupply Services (CRS) contract with NASA.
This launch follows a pair of successful launches in 2013, including the initial test launch in April and the 1st demonstration launch to the ISS in September.
Cygnus is loaded with approximately 2,780 pounds / 1,261 kilograms of cargo for the ISS crew for NASA including science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.
Among the research items packed aboard the Antares/Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.

Credit: Ken Kremer – kenkremer.comThere is also an ant farm aboard with ant colonies from Colorado, North Carolina and of course host state Virginia too. The goal is to study ant behavior in space in zero gravity and compare that to ants on Earth living under normal gravity.
So you can watch the launch either with your own eyes, if possible, or via the NASA TV webcast.
NASA Television coverage of the Antares launch will begin at 1 p.m. on Jan. 8 – www.nasa.gov/ntv
A launch on either Jan. 8 or Jan. 9 will result in a grapple of Cygnus by the Expedition 38 crew aboard the station on Sunday, Jan. 12 at 6:02 a.m. EDT.

Image of the X1.2 class solar flare from the Sun on January 7, 2014, as seen from the Solar Dynamics Observatory.
Solar astronomers have been keeping an eye on giant sunspot AR1944, and as it turned towards Earth today, the sunspot erupted with a powerful X1.2-class flare. NOAA’s Space Weather Prediction Center said the flare sparked a “strong radio blackout” today, and they have issued a 24 hour “moderate” magnetic storm watch indicating a coronal mass ejection (CME) associated with the flare may be heading towards Earth. A CME is a fast moving cloud of charged particles which can interact with Earth’s atmosphere to cause aurora, so observers in northern and southern latitudes should be on the lookout for aurora, possibly through January 10.
Here’s a video of the flare from the Solar Dynamics Observatory:
The SWPC forecasters said they are anticipating G2 (Moderate) Geomagnetic Storm conditions to occur on January 9, followed by G1 (Minor) levels January 10. NOAA estimates the CME headed towards Earth might produce a Kp number of 6.
The Earth-directed CME launched from AR1944 at 1832 UTC (1:32 p.m. EST) on January 7. Here’s an animation of the CME. Astronomers have said that this sunspot region remains “well-placed and energetic” so there could be subsequent activity.

According to SpaceWeather.com, AR1944 has “an unstable ‘beta-gamma-delta’ magnetic field,” making it ripe for activity. Here’s a quick video of today’s X-class flare showing the coronal wave:

If the dataset from the Kepler mission is any indication, the most common type of exoplanets in our galaxy aren’t Earth-sized rocky worlds or hot Jupiters. In fact, the most common type of exoplanet isn’t one that we see in our own neighborhood at all.
“Perhaps the most remarkable discovery by Kepler is the amount of planets between the size of Earth to four times the size of Earth,” said Geoff Marcy, professor of astronomy at University of California, speaking at the American Astronomical Society meeting this week in Washington D.C. “This is a size range that dominates the planet inventory from Kepler and it a size range not represented in our own Solar System. We don’t know for sure what these planets are made of and we don’t know how they form.”
These “mini-Neptunes” as Marcy called them, represent a huge sample in the Kepler data; about 75% of the planets found by Kepler vary in size between the Earth and Neptune, and for four years since the Kepler data have been rolling in, scientists have been trying to understand these planets.
“There’s been an enormous amount of measurements and quantitative work by the NASA Ames Kepler team,” Marcy said.
While masses and planet densities emerged from the work, astronomers still aren’t certain how they form or if they are made of rock, water or gas.

The team focused on about 42 of these planets. Two planets highlighted by Marcy in his presentation are thought to be rocky, and are named Kepler-99b and Kepler-406b. Both are forty percent larger in size than Earth and have a density similar to lead. The planets orbit their host stars in less than five and three days respectively, making these worlds too hot for life as we know it.
The team used Doppler measurements of the planets’ host stars to measure the reflex wobble of the host star, caused by the gravitational tug on the star exerted by the orbiting planet. The measured wobble reveals the mass of the planet: the higher the mass of the planet, the greater the gravitational tug on the star and hence the greater the wobble.
They also the measured transit timing variations (TTV) to determine how much neighboring planets can tug on one another causing one planet to accelerate and another planet to decelerate along its orbit.
These measurements allow for computing mass and densities of the planets, as well as figuring out the possible chemical composition of these worlds. The majority of the measurements suggest that the mini-Neptunes have a rocky core but some may have a gaseous outer shell of hydrogen or helium. Some might just be rocky with no outer envelope at all.
“What we think is happening is that some of these planets may have water on top of a rocky core,” Marcy said. “Larger planets might have the same rocky core with added gas. That’s how you get planets measuring from 1 to 4 earth radii. The planets with lower densities imply increasing amounts of gas on top of a rocky core.”

“Kepler’s primary objective is to determine the prevalence of planets of varying sizes and orbits. Of particular interest to the search for life is the prevalence of Earth-sized planets in the habitable zone,” said Natalie Batalha, Kepler mission scientist at NASA’s Ames Research Center. “But the question in the back of our minds is: are all planets the size of Earth rocky? Might some be scaled-down versions of icy Neptunes or steamy water worlds? What fraction are recognizable as kin of our rocky, terrestrial globe?”
The team said that the mass measurements produced by Doppler and TTV will help to answer these questions. The results hint that a large fraction of planets smaller than 1.5 times the radius of Earth may be comprised of the silicates, iron, nickel and magnesium that are found in the terrestrial planets here in the Solar System.
Armed with this type of information, scientists will be able to turn the fraction of stars harboring Earth-sizes planets into the fraction of stars harboring bona-fide rocky planets. And that’s a step closer to finding a habitable environment beyond the Solar System.
Marcy added later in the discussion that there’s one type of telescope that would most helpful: a Terrestrial Planet Finder type mission that would measure the temperature, size, and the orbital parameters of planets as small as our Earth in the habitable zones of distant solar systems. Alas, TPF was canceled.
The Gemini Planet Imager’s first light image of Beta Pictoris b (Processing by Christian Marois, NRC Canada)
The world’s newest and most powerful exoplanet imaging instrument, the recently-installed Gemini Planet Imager (GPI) on the 8-meter Gemini South telescope, has captured its first-light infrared image of an exoplanet: Beta Pictoris b, which orbits the star Beta Pictoris, the second-brightest star in the southern constellation Pictor. The planet is pretty obvious in the image above as a bright clump of pixels just to the lower right of the star in the middle (which is physically covered by a small opaque disk to block glare.) But that cluster of pixels is really a distant planet 63 light-years away and several times more massive — as well as 60% larger — than Jupiter!
And this is only the beginning.

While many exoplanets have been discovered and confirmed over the past couple of decades using various techniques, very few have actually been directly imaged. It’s extremely difficult to resolve the faint glow of a planet’s reflected light from within the brilliant glare of its star — but GPI was designed to do just that.
“Most planets that we know about to date are only known because of indirect methods that tell us a planet is there, a bit about its orbit and mass, but not much else,” said Bruce Macintosh of the Lawrence Livermore National Laboratory, who led the team that built the instrument. “With GPI we directly image planets around stars – it’s a bit like being able to dissect the system and really dive into the planet’s atmospheric makeup and characteristics.”
And GPI doesn’t just image distant Jupiter-sized exoplanets; it images them quickly.
“Even these early first-light images are almost a factor of ten better than the previous generation of instruments,” said Macintosh. ” In one minute, we were seeing planets that used to take us an hour to detect.”
Despite its large size, Beta Pictoris b is a very young planet — estimated to be less than 10 million years old (the star itself is only about 12 million.) Its presence is a testament to the ability of large planets to form rapidly and soon around newly-formed stars.
“Seeing a planet close to a star after just one minute, was a thrill, and we saw this on only the first week after the instrument was put on the telescope!” added Fredrik Rantakyro a Gemini staff scientist working on the instrument. “Imagine what it will be able to do once we tweak and completely tune its performance.”
Another of GPI’s first-light images captured light scattered by a ring of dust that surrounds the young star HR4796A , about 237 light-years away:
GPI first-light images of HR4796A. (Processing by Marshall Perrin, Space Telescope Science Institute.)
The left image shows shows normal light, including both the dust ring and the residual light from the central star scattered by turbulence in Earth’s atmosphere. The right image shows only polarized light. Leftover starlight is unpolarized and hence removed. The light from the back edge of the disk (to the right of the star) is strongly polarized as it reflects towards Earth, and thus it appears brighter than the forward-facing edge.
It’s thought that the reflective ring could be from a belt of asteroids or comets orbiting HR4796A, and possibly shaped (or “shepherded,” like the rings of Saturn) by as-yet unseen planets. GPI’s advanced capabilities allowed for the full circumference of the ring to be imaged.

GPI’s success in imaging previously-known systems like Beta Pictoris and HR4796A can only indicate many more exciting exoplanet discoveries to come.
“The entire exoplanet community is excited for GPI to usher in a whole new era of planet finding,” says physicist and exoplanet expert Sara Seager of the Massachusetts Institute of Technology. “Each exoplanet detection technique has its heyday. First it was the radial velocity technique (ground-based planet searches that started the whole field). Second it was the transit technique (namely Kepler). Now, it is the ‘direct imaging’ planet-finding technique’s turn to make waves.”
This year the GPI team will begin a large-scale survey, looking at 600 young stars to see what giant planets may be orbiting them.
“Some day, there will be an instrument that will look a lot like GPI, on a telescope in space. And the images and spectra that will come out of that instrument will show a little blue dot that is another Earth.”
– Bruce Macintosh, GPI team leader
The observations above were conducted last November during an “extremely trouble-free debut.” The Gemini South telescope is located near the summit of Cerro Pachon in central Chile, at an altitude of 2,722 meters.

WALLOPS ISLAND, VA – Catching a slim weather break amidst the monster blizzard and unprecedented arctic air low temperatures afflicting the central and northern United States, Orbital Sciences Corp. is marching forward with plans for a spectacular daylight blastoff of the firms privately developed Antares rocket and Cygnus cargo spacecraft on Wednesday, Jan. 8 from a beachside pad at NASA Wallops Island, VA – on a critical mission for NASA bound for the Space Station carrying a huge cargo of vital science experiments.
Here’s our complete guide on “How to See the Antares/Cygnus Jan. 8 Blastoff” – chock full of viewing maps and trajectory graphics (above and below) from a variety of prime viewing locations; including historic landmarks in Washington, DC., NYC, Baltimore, Philadelphia, Virginia and more.
The cold weather, daytime Antares liftoff is currently scheduled for 1:32 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops, Virginia.
Due to continuing extremely cold weather conditions forecast for mid week, the launch could slip a day to Thursday, Jan. 9 when slightly warmer temperatures are expected, but it looks acceptable at this time.
This flight was originally due to blastoff at night in mid-December 2013 but was postponed due to the unexpected need for urgent repairs to get the stations critical cooling system restored to full operation following a malfunction. The fixes were accomplished during a pair of pre-Christmas spacewalks by American astronauts Rick Mastracchio and Mike Hopkins, paving the way for the Antares/Cygnus rescheduled liftoff.

And although it’s now moved to daylight due to orbital mechanics, the two stage Antares rockets exhaust plume should easily be visible to many millions of residents up and down the US East Coast spanning from South Carolina to Massachusetts – weather permitting.
Antares will be able to be seen by spectators inland as well, reaching potentially into portions of West Virginia, western Pennsylvania and New England depending on cloud cover.
For example; Here’s the expected view from the US Capitol – for all the politicians who decide NASA’s budget as well as myriads of tourists visiting from all across the globe.

And with yet another cold arctic air mass gushing towards eastwards, its certain to be frigid in many regions – so be sure to dress warmly.
The flight is designated the Orbital-1, or Orb-1 mission.
Orb-1 is the first of eight commercial cargo resupply missions to the ISS by Orbital under its Commercial Resupply Services (CRS) contract with NASA.
Battery Park, NYC
This launch follows a pair of successful launches in 2013, including the initial test launch in April and the 1st demonstration launch to the ISS in September.
So here’s your chance to witness a mighty rocket launch – from the comfort of your home from locations along the east coast.
Naval Station Norfolk, Virginia
Best viewing of all will be in the mid-Atlantic region closest to Wallops Island.
If you have the opportunity to observe the launch locally, you’ll get a magnificent view and hear the rockets thunder at either the NASA Wallops Visitor Center or the Chincoteague National Wildlife Refuge/Assateague National Seashore.
For more information about the Wallops Visitors Center, including directions, see: http://www.nasa.gov/centers/wallops/visitorcenter
The rocket was rolled out to the Wallops launch pad on Sunday by Orbital’s technicians.

Among the research items packed aboard the Antares/Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
Of course you can still view the launch live via the NASA TV webcast.
NASA Television coverage of the Antares launch will begin at 1 p.m. on Jan. 8 – www.nasa.gov/ntv
A launch on either Jan. 8 or Jan. 9 will result in a grapple of Cygnus by the Expedition 38 crew aboard the station on Sunday, Jan. 12 at at 6:02 a.m. EDT.
Weather outlook appears rather promising at this time – 90% favorable chance of lift off.

Gas planets aren’t always bloated, monstrous worlds the size of Jupiter or Saturn (or larger) they can also apparently be just barely bigger than Earth. This was the discovery announced earlier today during the 223rd meeting of the American Astronomical Society in Washington, DC, when findings regarding the gassy (but surprisingly small) exoplanet KOI-314c were presented.
“This planet might have the same mass as Earth, but it is certainly not Earth-like,” said David Kipping of the Harvard-Smithsonian Center for Astrophysics (CfA), lead author of the discovery. “It proves that there is no clear dividing line between rocky worlds like Earth and fluffier planets like water worlds or gas giants.”
Discovered by the Kepler space telescope — ironically, during a hunt for exomoons — KOI-314c was found transiting a red dwarf star only 200 light-years away — “a stone’s throw by Kepler’s standards,” according to Kipping. (Kepler’s observation depth is about 3000 light-years.)
Relative size comparison of KOI-314c and Earth; both have similar mass. (J. Major)
Kipping used a technique called transit timing variations (TTV) to study two of three exoplanets found orbiting KOI-314. Both are about 60% larger than Earth in diameter but their respective masses are very different. KOI-314b is a dense, rocky world four times the mass of Earth, while KOI-314c’s lighter, Earthlike mass indicates a planet with a thick “puffy” atmosphere… similar to what’s found on Neptune or Uranus.
Unlike those chilly worlds, though, this newfound exoplanet turns up the heat. Orbiting its star every 23 days, temperatures on KOI-314c reach 220ºF (104ºC)… too hot for water to exist in liquid form and thus too hot for life as we know it.
In fact Kipping’s team found KOI-314c to only be 30 percent denser than water, suggesting that it has a “significant atmosphere hundreds of miles thick,” likely composed of hydrogen and helium.
It’s thought that KOI-314c may have originally been a “mini-Neptune” gas planet and has since lost some of its atmosphere, boiled off by the star’s intense radiation.
Not only is KOI-314c the lightest exoplanet to have both its mass and diameter measured but it’s also a testament to the success and sensitivity of the relatively new TTV method, which is particularly useful in multiple-planet systems where the tiniest gravitational wobbles reveal the presence and details of neighboring bodies.
“We are bringing transit timing variations to maturity,” Kipping said. He added during the closing remarks of his presentation at AAS223: “It’s actually recycling the way Neptune was discovered by watching Uranus’ wobbles 150 years ago. I think it’s a method you’ll be hearing more about. We may be able to detect even the first Earth 2.0 Earth-mass/Earth-radius using this technique in the future.”

SpaceX began 2014 with a spectacular big bang for private space today, Jan. 6, when the firms next generation Falcon 9 rocket blasted off for the first time this year and successfully delivered the Thaicom 6 commercial broadcasting satellite to its target orbit.
The new, next generation Falcon 9 rocket lifted off at 5:06 p.m. EST (2206 GMT) from Cape Canaveral Air Force Station, Florida with the Thai payload.
The sunset SpaceX launch from the Florida Space Coast took place precisely on time with ignition of the nine Merlin 1-D first stage engines at Space Launch Complex 40.
The launch was broadcast live via a SpaceX webcast.
The nine engines on the 224 foot tall Falcon 9 v1.1 rocket generate 1.3 million pounds of thrust, about 50% more than the initial Falcon 9.
The second stage Merlin vacuum engine fired twice as planned.
The first firing began approximately 184 seconds into flight and lasted five minutes and 35 second to deliver Thaicom 6 into its parking orbit.

The engine relit for a second burn eighteen minutes later and lasted just over one minute to carry the satellite to its final geostationary transfer orbit.
The restart of the Falcon 9 second stage is a requirement for all geostationary transfer missions.

31 minutes after liftoff the Thaicom 6 spacecraft separated from the Falcon 9 launch vehicle and was placed into the desired geosynchronous transfer orbit of 295 x 90,000 km geosynchronous at 22.5 degrees inclination.
SpaceX said in a statement that, “The Falcon 9 launch vehicle performed as expected, meeting 100% of mission objectives.”
SpaceX did not attempt to recover the first stage booster on this mission, SpaceX spokeswoman Emily Shanklin told me. “We may try on the next flight.”

This marks the second launch of the upgraded Falcon 9 in just over a month, following closely on the heels of the maiden flight from Cape Canaveral on Dec. 3 with another commercial satellite, namely SES-8.
“Today’s successful launch of the THAICOM 6 satellite marks the eighth successful flight in a row for Falcon 9,” said Gwynne Shotwell, President of SpaceX. “SpaceX greatly appreciates THAICOM’s support throughout this campaign and we look forward to a busy launch schedule in 2014.”
Both the Thaicom-6 and SES-8 satellites were built by Orbital Sciences, one of SpaceX’s chief competitors in the commercial space race, making for strange bedfellows.
The new Falcon 9 is the key to fulfilling SpaceX’s future launch manifest of nearly 50 payloads worth billions of dollars for a diverse customer base.

The next gen Falcon 9 will also launch the human rated SpaceX Dragon to the ISS in a bid to restore America’s human spaceflight capability.
A pair of critical Falcon 9/Dragon abort tests are planned for 2014. Read my new article and discussion with SpaceX CEO Elon Musk – here.
The next SpaceX Dragon cargo launch to the ISS is currently scheduled for Feb. 22, said SpaceX spokeswoman Emily Shanklin told Universe Today.

This image was captured by NOAA's GOES-East satellite on January 6, 2014 at 1601 UTC/11:01 a.m. EST. A frontal system that brought rain to the coast is draped from north to south along the U.S. East Coast. Behind the front lies the clearer skies bitter cold air associated with the Polar Vortex.
If you live in the north and eastern part of the US, you’re probably experiencing some frigid weather. You’re probably also hearing people talk about something called a “polar vortex.”
Just what is a polar vortex and why is it making the temperatures so cold?
This image was captured by NOAA’s GOES-East satellite on Jan. 6, 2014, at 11:01 a.m. EST (1601 UTC). A frontal system that brought rain and snow to the US East coast is seen draped from north to south, and behind the front lies the clearer skies bitter cold air associated with the polar vortex. Also visible in the image is snow on the ground in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Michigan, Iowa and Missouri. The clouds over Texas are associated with a low pressure system centered over western Oklahoma that is part of the cold front connected to the movement of the polar vortex.
NASA explains that the polar vortex is a “whirling and persistent large area of low pressure, found typically over both North and South poles.”
Weather reports say the northern polar vortex was pushing southward over western Wisconsin and eastern Minnesota on Monday, Jan. 6, 2014, and was bringing frigid temperatures to half of the continental United States. It is expected to move northward back over Canada toward the end of the week.
More about the polar vortex:
Both the northern and southern polar vortexes are located in the middle and upper troposphere (lowest level of the atmosphere) and the stratosphere (next level up in the atmosphere). The polar vortex is a winter phenomenon. It develops and strengthens in its respective hemispheres’ winters as the sun sets over the polar region and temperatures cool. They weaken in the summer. In the Northern Hemisphere, they circulate in a counterclockwise direction, so the vortex sitting over western Wisconsin is sweeping in cold Arctic air around it.
