Astronomers Without Borders – those great folks who do science outreach around the world – is getting ready for the next solar eclipse, which takes place on November 3, 2013. A partial eclipse will be visible across a wide swath of Africa and AWB needs your help so that tens of thousands of eclipse glasses can be sent to schools in Africa in time for the eclipse.
“We’re working with the IAU’s Office of Astronomy for Development who has contacts working with schools and able to distribute the glasses to them,” Mike Simmons, who leads AWB, told Universe Today via email. “The opportunity for this came up late so we’re working very hard to make it happen in the short time we have left.”
Simmons added that this is a rare opportunity to expose students to science in a region where science resources are often non-existent, and AWB will be giving the glasses to schools at no charge.

The AWB website says that schools have been identified and vetted by partner organizations in each country in Africa, and distribution networks have been verified. Every donated pair of eclipse glasses WILL reach a student for use for the eclipse. The International Astronomical Union’s Office of Astronomy for Development, which is based in Cape Town, South Africa, is providing invaluable support and assistance through their many contacts across Africa.
This program depends entirely on donations.
“There’s no question we can get all the donations that are needed as long as we get the word out in time,” Simmons said.
Please consider donating, as AWB does amazing work.
“We do probably a half-million dollars in programs each year based on the hard work of passionate amateur astronomers and educators around the world,” Simmons said, “all on way less than $25,000 a year.”
This is a great astronomy outreach organization that really could use financial help of any kind, so feel free to donate to their general cause, as well.
You can also purchase eclipse glasses for your own use from AWB here.
Everyone knows that the Moon goes through phases, but let’s talk about why it does. It comes down to illumination, which in this case, all originates from our nearby star.
Our Moon orbits around our planet, and this Earth-Moon system orbits around the Sun.
Even though we only see light on part of the Moon, from the perspective of the Sun, half of it is always illuminated.
Stuck here on Earth, we see the Moon in various phases of illumination as it completes a 27.3 day orbit around the Earth.
As The Moon travels around us we see it pass through its phases. It goes from New Moon, to Full Moon and back to new Moon again.
Crescent Moons are when it’s less than half illuminated, and gibbous when it’s more than half.
“Waxing” means that the Moon becomes more illuminated night-by-night, and the term “waning” means that it’s getting less illuminated each night.
New Moon – When the illuminated side of the Moon is away from the Earth. The Moon and the Sun are lined up on the same side of the Earth, so we can only see the shadowed side. This is also the time that you can experience solar eclipses, when the Moon passes directly in front of the Sun and casts a shadow onto the surface of the Earth. During a new moon, we can also see the reflected light from the Earth, since no sunlight is falling on the Moon – this is known as earthshine.
Crescent – The crescent moon is the first sliver of the Moon that we can see. From the northern hemisphere, the crescent moon has the illuminated edge of the Moon on the right. This situation is reversed for the southern hemisphere.
First Quarter – Although it’s called a quarter moon, we actually see this phase when the Moon is half illuminated. This means that the Sun and the Moon make a 90-degree angle compared to the Earth.
Waxing Gibbous – This phase of the Moon occurs when the Moon is more illuminated that half, but it’s not yet a full Moon.
Full Moon – This is the phase when the Moon is brightest in the sky. From our perspective here on Earth, the Moon is fully illuminated by the light of the Sun. This is also the time of the lunar month when you can see lunar eclipses – these occur when the Moon passes through the shadow of the Earth.
Waning Gibbous – In this lunar phase, the Moon is less than fully illuminated, but more than half.
Last Quarter – At this point of the lunar cycle, the Moon has reached half illumination. Now it’s the left-hand side of the Moon that’s illuminated, and the right-hand side in darkness (from a northern hemisphere perspective).
Crescent – This is the final sliver of illuminated moon we can see before the Moon goes into darkness again.
If you ever get the chance to travel to the other hemisphere, you’ll immediately notice how unfamiliar the Moon behaves – it’s upside down.
If you live in the Northern Hemisphere, after a New Moon the crescent begins on the right-side. But if you’re in the Southern Hemisphere, it’s reversed, with the illumination starting on the left side.
Weird.
The alignment of the Sun, Earth and Moon can lead to some fantastic astronomical events.
When the Moon is new, it can pass in between the Earth and the Sun, casting its shadow down on our planet. As you know, a solar eclipse.
Solar Eclipse as seen by Hinode SatelliteYou’d think we would see a solar and lunar eclipse every month, but we don’t because the Moon’s orbit is inclined relative to the Sun.
Most months, the Moon is either above or below the Sun in the sky, so they just don’t line up perfectly.
Phases of Venus. Image credit: ESOOne more thing, you might not know that Venus also goes through phases. When the planet is on the other side of the Sun from us, we see it as a nearly complete disk. But when Venus is on our side, just about to pass into the glow of the Sun, it’s a thin crescent, just like how we see the Moon.
I hope this gives you a better understanding of why the Moon goes through its phases every month, and the interesting relationship between the Earth, the Sun, and the Moon.

“Primordial hydrogen” sounds like a great name for a band. It’s also a great thing to find when you’re looking at a galaxy. This ancient gas is a leftover of the Big Bang, and astronomers discovered it in a faraway star-forming galaxy that was created when the universe was young.
A continuous stream of gas was likely responsible for a cornucopia of star formation that took place about 10 billion years ago, when galaxies were churning out starbirths at a furious rate.
The astronomers spotted the gas by using a quasar that lit up the fuel from behind. Quasars a handy tool to use if you want to illuminate something, because even though quasars don’t live for very long in cosmic terms — they occur when matter falls into a ginormous black hole — they are extremely bright. Since the gas absorbs the light at certain frequencies, the absorption lines that show up in spectrometers reveal information about the composition, temperature and density of the gas.
“This is not the first time astronomers have found a galaxy with nearby gas, revealed by a quasar. But it is the first time that everything fits together,” stated Neil Crighton, who is with the Max Planck Institute for Astronomy and Swinburne University and led the research. His team found the galaxy using the Keck I telescope in Hawaii.
“The galaxy is vigorously forming stars,” added Crighton, “and the gas properties clearly show that this is pristine material, left over from the early universe shortly after the Big Bang.”
Q1442-MD50 (as the galaxy is called) is 11 billion light years away from us — pretty close to the start of the universe about 13.8 billion years ago. The quasar that lit it up is called QSO J1444535+291905.
“Since this discovery is the result of a systematic search, we can now deduce that such cold flows are quite common,” stated Joseph Hennawi, the leader of the ENIGMA research group at the Max Planck Institute for Astronomy. “We only had to search 12 quasar-galaxy pairs to discover this example. This rate is in rough agreement with the predictions of supercomputer simulations, which provides a vote of confidence for our current theories of how galaxies formed.”

“Talk about a selfie!” wrote former astronaut Clay Anderson on Twitter yesterday (Oct. 1). He posted that comment along with a favorite photo from Expedition 15, when he was standing in restraints on the robotic Canadarm2. Off in the distance, he saw his shadow against the solar array panels of a Soyuz spacecraft.
That got us thinking — what are the best astronaut selfies? Below are some of our favourites (some intentional, some not) from over the years. Any that we have missed? Let us know in the comments!

No, this isn’t The Onion… as a concerned consumer of all that is space news, you have indeed arrived at the cyber-doorstep of Universe Today.
I’ll admit though, that we did do a double take about a week back when a peculiar claim came our way via the Iranian Space Agency. Yes, there is an Iranian Space Agency, and it’s kind of frightening that they remain open for business while NASA is largely shutdown.
In mid-September, senior Iranian space program official Mohammad Ebrahimi issued a statement that Iran will attempt another bio-capsule launch “within 45 days”. The unwilling occupant: a Persian cat.
Apparently, a rabbit, a mouse, and another “Space Monkey” were also in the running. Iran’s space program is shrouded in secrecy, and most launches are only announced after they’ve been conducted. This is a convenient political strategy for hiding launch failures that harkens back to the early days of the Cold War. You’re right in guessing that the Iranian Space Agency probably won’t hold a Tweetup for this one. Many western analysts see the Iran’s space effort as a thinly veiled attempt to develop its long range ballistic missile technology. Along with Israel, Iran remains the only Middle Eastern country with the proven technology to conduct indigenous satellite launches.
Iran has stated that it hopes to put an astronaut in orbit by 2019. The Pishgam (or “Pioneer” in Farsi) 2 bio-capsule launch could occur from a mobile launcher at Semnan Space Center as early as October 15th. Satellite sleuths are also expecting activity at Semnan to pick up this month, with the possible launch of SharifSat atop a Safir 1-B rocket, and Iran’s Toulou satellite aboard a rumored new launch vehicle.
Iran successfully became a space-faring nation with the launch of its 27 kilogram Omid satellite on February 2nd, 2009. It isn’t immediately clear if the upcoming launch will be an orbital launch or a sub-orbital ballistic shot. If Pisgam-2 achieves orbit, said “Space Cat” would become the first feline to circle the Earth. If recovery is attempted —again, Iran is always nebulous as to their intentions— it would also be the first time they’ve achieved a return from orbit.
But is “Space Cat” even a reality?
Iran has been caught red-handed before playing a shell game with the media in terms of its space program. Earlier this year, “Monkey-gate” erupted, as before-and-after images from the Pisgam-1 bio-capsule suborbital launch clearly showed two different monkeys before and after the flight:
Monkey business? Iran displayed a decidedly different looking monkey before, during, and after launch earlier this year! (Credit: Iran News Agency).
Clearly, Iran and other ‘Axis of Evil’ countries definitely need to sharpen their Photoshop, or at least their monkey-switching skills. Either said monkey launch never actually occurred, or (more likely), the unwilling Iranian space primate never survived the flight.
Perhaps this is why Iran decided on a feline occupant this time around, for possible ease of replacement?
PETA, the People for the Ethical Treatment of Animals, have also issued a statement concerning the impending launch of “Space Cat” by Iran, calling the action an “archaic experiment, a throwback to the primitive techniques of the 1950’s.”
NASA did entertain the idea of “Catronauts” early in the space program. (Credit: NASA).
The U.S. and the Soviet Union launched animals into space as a prelude to human spaceflight. On November 3rd, 1957, Laika the dog became the first animal to orbit the Earth. Laika perished is space due to overheating, as did several unfortunate monkeys that were launched on the first US ballistic tests.
Russia still conducts the occasional launch of animals into space, including the Bion-1M “Space Zoo” mission earlier this year. The Bion missions allow for scientists to dissect the specimens afterwards to study the effects of a month in zero-g, something you can’t do with humans.
And the U.S. did once fly cats in zero-g aboard its Convair C-131 “Vomit Comet” aircraft, as can be seen in this bizarre video:
But the first cat in space was actually launched by France atop a Veronique AGI sub-orbital rocket 50 years ago this month on October 18th, 1963. It would be ironic if Iran conducted it launch this month on the anniversary! The story goes the Felix, the original cat slated for the flight, escaped just prior to launch from the Sahara desert Hammaguir test site in Algeria, and was replaced by the “backup crew,” a female cat named Felicette. Felicette survived the 15 minute flight, reaching an apogee of 217 kilometres. A follow-up launch of a second cat six days later wasn’t so lucky.

As always, Iran’s intentions for the future of its space program remain hidden. Their current launch capabilities remain limited, and are a far cry from being able to hoist a human into orbit anytime soon. If the launch of “Space Cat” does come to pass this month, it’ll be over protests from animal rights groups and the general public. Hey, didn’t the former Iranian president Mahmoud Ahmadinejad say earlier this year after “Monkey-Gate” that he was willing to be “The first Iranian to be sacrificed by the scientists of my country and go into space” as the first Iranian astronaut? Is he really going to let Space Cat upstage him?
Felix and Felicette where also commemorated on several African postage stamps. (Credit: Majorie-art.voila.net).

Ever stood outside looking at the aurora and felt as though it was swirling just a short distance above your head? It’s hard to judge altitude when looking at sky phenomena because there are few landmarks above us. (The moon effect at the horizon is an example.) But it turns out there is a way to measure aurora altitude.
The eerie, green glow of the Northern Lights swirls about in the video you see above. A group of researchers used a unique but simple technique to measure how high the electrons were during the dazzling light display: they mounted two digital SLRs eight kilometers (five miles) apart in Alaska, and used that old astronomical friend, parallax, to measure distances.
“Using the parallax of the left-eye and the right-eye images, we can calculate the distance to the aurora using a [triangulation] method that is similar to the way the human brain comprehends the distance to an object,” stated Ryuho Kataoka, an associate professor at the National Institute of Polar Research in Japan. “Parallax is the difference in the apparent position of an object when observed at different angles.”
Altitude measurements have been done before using this technique, but it’s the first time digital SLRs were employed, the research team said. A typical aurora has electrons that are between 90 kilometers and 400 kilometers (55 miles and 249 miles) high.
By the way, for all the amateur astronomy photographers, there’s a potential chance for you to get involved with future research activities.
“Commercially available GPS units for digital SLR cameras have become popular and relatively inexpensive, and it is easy and very useful for photographers to record the accurate time and position in photographic files,” said Kataoka. “I am thinking of developing a website with a submission system to collect many interesting photographs from night-sky photographers over the world via the Internet.”
From the Cat’s Eye to the Eskimo, planetary nebulae are arguably among the most dazzling objects in the Universe. These misnamed stellar remnants are created when the outer layers of a dying star blows off and expands into space. However, they can look radically different from one another, revealing complicated histories and structures.
But recently, astronomers have argued that some of the most exotic shapes are the result of not one, but two stars at the center. It is the interaction between the progenitor star and a binary companion that shapes the resulting planetary nebula.
The archetypal planetary nebula is spherical. Most planetary nebulae, however, have been shown to be non-spherical, complex structures.
“LoTr 1 is one such planetary nebula, but with a twist,” Amy Tyndall – a graduate student at the University of Manchester and lead author on the study – told Universe Today. It has not one star at its center but two. The binary central star system consists of a faint, hot white dwarf and a cool companion – a rapidly rotating giant.

LoTr 1 was first discovered by astronomers using the 1.2 meter telescope at the Royal Observatory in Edinburgh, Scotland. At the time it seemed that LoTr 1 was similar to a particular group of 4 planetary nebulae (Abell 35, Abell 70, WeBo 1 and LoTr 5), all of which had a central binary star system.
Another common factor amongst this particular group is that in most cases the companion star seemed to be a barium star – a cool giant that shows relatively large amounts of barium. Before the planetary nebula forms, the progenitor star dredges up an excess amount of Barium on its surface. It then releases a Barium-enriched stellar wind, which falls on its companion star.
“After the stellar envelope is ejected to form the surrounding nebula, the giant star evolves into a white dwarf, while the contaminated star retains the barium from the wind as it continues to evolve to form a Barium star,” explains Tyndall.
Tyndall and her collaborates set out to see if the companion star within LoTr 1 was in fact a Barium star. They acquired data from telescopes in both Chile and Australia and compared their results to the two other elusive planetary nebulae in the group: Abell 70 and WeBo 1.
“If barium is indeed present, it would be a good step further towards our understanding of how mass is transferred between stars in a binary system, and how that subsequently affects the formation and morphology of planetary nebulae,” says Tyndall.
While the results show that LoTr 1 does consist of binary star system, the companion star is not a Barium star. But a null result is still a result. “LoTr 1 remains an interesting object to us as it shows that we still have huge gaps in our knowledge as to how these stunning objects form,” Tyndall told Universe Today.
Without the presence of Barium, it would appear at first that little mass was transferred to the companion star. However, the companion star is rotating rapidly, which is a direct consequence of mass transfer. The most plausible explanation is that the mass was transferred before the barium could be dredged up to the stellar surface.
If the stellar evolution was cut short this way then there will be detectable evidence in the properties of the white dwarf. The next step will be to take another look at this odd planetary nebula in hopes of better understanding the complexities of this system.

Once-active “supervolcanoes” in northern Mars likely spewed ash and dust thousands of miles away, producing powdery deposits noticed by the NASA’s Curiosity and Opportunity rovers closer to the equator, a new study suggests.
The scientists suspect that irregularly shaped craters in Arabia Terra, which is in the northern highlands of Mars, are leftovers of huge volcanoes from eons ago. Until now, those areas weren’t pegged as volcanoes at all.
“Discovering supervolcanic structures fundamentally changes how we view ancient volcanism on Mars,” stated Joseph Michalski, a Mars researcher at the Natural History Museum in London and the Planetary Institute in Tucson, Arizona.
“Many Martian volcanoes are easily recognized from their massive shield-shaped structure, similar to what we see in Hawaii. But these are relatively youthful features on Mars, and we have always wondered where the ancient volcanoes are. It is possible that the most ancient volcanoes were much more explosive and formed structures similar to what we now see in Arabia Terra.”
As some scientists believe that the crust of Mars was thinner than it is now, this would let magma erupt to the surface before it could release gases inside the crust, the team added. The finding also has implications for predicting the ancient atmosphere and looking at habitability.
“If future work shows that supervolcanoes were present more widely on ancient Mars, it would completely change estimates of how the atmosphere formed from volcanic gases, how sediments formed from volcanic ash and how
habitable the surface might have been,” Michalski added.

HiRISE image of comet ISON from Mars orbit (NASA/JPL/University of Arizona)
It’s not much to look at, but there it is: the incoming comet ISON (aka C/2012 S1) as seen by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter. An enlarged version of one of four just-released images, this represents a 256-by-256-pixel patch of sky imaged by HiRISE on Sunday, September 29. ISON is the fuzzy blob at center, 8.5 million miles (13.8 million km) away.
See all four images below:
HiRISE images of ISON on Sept. 29, 2013 (NASA/JPL/University of Arizona)
HiRISE researchers Alan Delamere and Alfred McEwen explained in a news release:
Based on preliminary analysis of the data, the comet appears to be at the low end of the range of brightness predictions for the observation. As a result, the image isn’t visually pleasing but low coma activity is best for constraining the size of the nucleus. This image has a scale of approximately 8 miles (13.3 km) per pixel, larger than the comet, but the size of the nucleus can be estimated based on the typical brightness of other comet nuclei. The comet, like Mars, is currently 241 million kilometers from the Sun. As the comet gets closer to the sun, its brightness will increase to Earth-based observers and the comet may also become intrinsically brighter as the stronger sunlight volatilizes the comet’s ices.
More images of ISON from HiRISE are expected as the comet came even closer to Mars, approaching within 6.7 million miles (10.8 million km), but the illumination from those angles may not be as good.
NOTE: These are preliminary single (non-stacked) images, and still contain noise and background stars – hence the fuzziness. Plus HiRISE was not really designed for sky imaging! (Thanks to HiRISE team member Kristin Block for the info.)
So even though it’s at the “low end” of brightness predictions in these HiRISE images, ISON certainly hasn’t “fizzled” like some reports claimed earlier this year (although just how bright it will get in our skies remains to be seen.)
Comet ISON will make its closest pass of the Sun (perihelion) on November 28, 2013, coming within 724,000 miles (1.16 million km) before heading back out into the Solar System… if it survives the encounter, that is. Read more about how to view ISON here and here.
Worried about ISON’s first (and possibly last) visit to the inner Solar System? Don’t be. Recent rumors of comet-caused catastrophe are greatly exaggerated… read more on David Dickinson’s article Debunking Comet ISON Conspiracy Theories (No, ISON is Not Nibiru).

As Day 2 of the United States government shutdown continues, some short-term effects are already in evidence when it comes to Earth and space.
Most of the NASA and National Oceanic and Atmospheric Administration (NOAA) websites are offline. Social media updates are silent. At NASA, 97% of agency employees are off work and media reports indicate that 55% of NOAA’s employees are furloughed.
If the shutdown lasts for very long, however, long-term programs could feel the pain. This includes a couple of Mars missions NASA is developing, as well as Earth-based climate research and satellite observation from NOAA.
Mars 2020
A twin rover to Mars Curiosity, called Mars 2020 for now, is expected to leave for the Red Planet in 2020 and do investigations into past life and habitability. Planning is still in the early stages, but an announcement of opportunity for science investigators was supposed to happen on Oct. 8. Notices of intent were due Oct. 15.
“The preproposal conference, scheduled for 10/8, may be rescheduled and the due date for NOIs (currently 10/15) could be delayed, if the government is still shut down closer to those dates,” NASA officials wrote in an update before the shutdown on Monday.

MAVEN
As widely reported yesterday, the next Mars orbiter from NASA is expected to lift off from Earth on Nov. 18. Now, however, preparatory work has ceased and there is some concern from team members that it will miss the launch window, which extends into December. At worst, this means MAVEN’s launch could be delayed until 2016, when the next opportunity opens.
“The hardware is being safed, meaning that it will be put into a known, stable, and safe state,” Bruce Jakosky, MAVEN’s principal investigator, told Universe Today‘s Ken Kremer yesterday. “We’ll turn back on when told that we can. We have some margin days built into our schedule.”
NOAA
As with NASA, NOAA is keeping up with mission-critical activities — which in their case, includes weather forecasting. Long-term climate research, however, is reportedly being shelved.
“For example, Harold Brooks, a top tornado researcher who works at the National Severe Storms Laboratory in Norman, Okla., reported his furlough notice on Facebook on Tuesday,” Climate Central wrote on Oct. 1. “Much of the staff at NOAA’s Earth Systems Research Lab and the Geophysical Fluid Dynamics Laboratory, except for positions related to maintaining computing resources, have also been furloughed. Those two labs are heavily involved in NOAA’s climate research programs.”

Observers are also worried that a lengthy shutdown could push back the time when new weather satellites become available. There have been multiple reports about a “weather satellite gap” coming in the United States as many of NOAA’s geostationary and polar-orbiting satellites are nearing the end of their expected lives. The Subcommittees on Oversight and Environment held hearings into this issue in September.
What’s still online?
These are some of the programs that are still happening at NASA and NOAA:

NASA:
Bare-bones management on programs such as the International Space Station and several robotic missions that are already in operation (such as the Lunar Atmosphere and Dust Environment Explorer (LADEE).
Certain missions are in critical phases that could be hurt if work stops, such as the James Webb Space Telescope, which is undergoing cryogenic testing on some of its instruments.
Several missions run out of the Jet Propulsion Laboratory and Applied Physics Laboratory are still running as usual, according to the Planetary Society, as these receive contract money from NASA; this means Mars Curiosity is still working, for example.
The Mars Reconnaissance Orbiter’s HiRISE camera is still snapping pictures, its Twitter account reported, which is positive given that it was intended to snap shots of Comet ISON during its closest approach to Mars yesterday.
The decades-long Landsat Earth observation program is still operating, according to The Atlantic, with data being sent back to Earth as usual. The difference is this information won’t be packaged as usual until government operations restart.
NOAA (all information according to this Department of Commerce document):
The Office of Oceanic and Atmospheric Research will keep 73 employees on board “to ensure continuity of crucial long-term historical climate records, and real-time regular research to support ongoing weather and air quality prediction services,” NOAA said.
184 employees will stay with the Environmental Satellite and Data Information Service for command and control of several satellites for NOAA and the Department of Defense.
474 employees will remain with the National Marine Fisheries Service. 174 are funded in another form besides appropriations. The others are a mix of law enforcement, fisheries management and property protection officials.
490 employees are with the Office of Marine and Aviation Operations for observational data collection related to weather forecasting.
173 employees are with the National Ocean Service. 17 are funded outside of appropriations, while the 156 remaining “are required to protect against imminent and significant threats to life and property by supporting safe maritime commerce in U.S. waters, including real-time water level data for ships entering U.S. ports, critical nautical chart updates, and accurate position information,” NOAA stated. Some are also monitoring marine health aspects such as algal blooms.
There are 19 IT-related employees and 20 employees providing support services.
The large bulk of employees still at work, 3,935 people, are with the National Weather Service to keep up weather forecasting.
There’s no word yet on when government employees could go back to work. Congress representatives are jousting over the implementation of a spending bill to keep the money flowing to government departments. One big issue: whether to include the Affordable Care Act, sometimes dubbed Obamacare, in the bill.
Another deadline is looming, too. Treasury Secretary Jack Lew has warned repeatedly that on Oct. 17, if the debt ceiling is not raised, the United States government may default on some financial obligations.
