The 2012 fiscal year appropriation bill, marked up today by the Senate, allows for continued funding of the James Webb Space Telescope and support up to a launch in 2018! Yes, it looks like this bird is going to fly.

The James Webb Space Telescope will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System. JWST will be a large infrared telescope with a 6.5-meter primary mirror.

Thanks to everyone who contacted their representatives and expressed their support of the JWST, to all the websites out there that made it particularly simple to do so, and of course to all the state representatives who stood behind the program and didn’t allow it to get mothballed. The space science community thanks you and the current and future generations of astronomers, physicists, cosmologists and explorers thank you.

“In a spending bill that has less to spend, we naturally focus on the cuts and the things we can’t do. But I’d like to focus on what we can do. The bill invests more than $12 billion in scientific research and high impact research and technology development, to create new products and new jobs for the future.”

– CJS Subcommittee Chairwoman Barbara Mikulski

In addition to continued funding for the telescope the 2012 bill also allots the National Aeronautics and Space Administration $17.9 billion (a reduction of $509 million or 2.8 percent from the 2011 enacted level) and preserves NASA’s portfolio balanced among science, aeronautics, technology and human space flight investments, including the Orion Multipurpose Crew Vehicle, the heavy lift Space Launch System, and commercial crew development.

In this tighter economy, all of the agencies funded under the bill are also called on to be better stewards of taxpayers’ dollars, and waste and overspending will be much more closely monitored.

Read the bill summary here.

Go JWST!

NOTE: While the JWST program has been specifically included in today’s markup, the bill itself still needs to be approved by the full appropriations committee and then go to the Senate floor for a vote. It then must be reconciled with the House version before receiving final appropriation. Still, this is definitely one step closer to getting the JWST off the ground!

You can show your continued support for the JWST by liking the Save the James Webb Space Telescope Facebook page and – even more importantly – by contacting your congressperson and letting them know you care!

A Martian Memorial to 9/11

As we approach the tenth anniversary of the September 11 World Trade Center attacks (has it already been ten years??) countless hearts and minds will be remembering the fateful day our world changed forever, and the many people who tragically lost their lives in the catastrophic collapse of the twin towers. Memorial events will be held in many locations around the world… and even, in a small yet poignant way, on another world. For, unknown to many, two pieces of the World Trade Center are on the surface of Mars: one affixed to the rover Spirit which sits silently in its permanent position near a small plateau called “Home Plate” and the other on its sister rover Opportunity, currently exploring the rim of the vast Endeavour crater.

Much more than scientific exploration tools, these rovers are also interplanetary memorials to the victims of 9/11.

In September of 2001 workers at Honeybee Robotics in lower Manhattan were busy preparing the Rock Abrasion Tools that the twin rovers Spirit and Opportunity would each be equipped with, specialized instruments that would allow scientists to study the interiors of Martian rocks. After the World Trade Center attacks occurred, the company wanted a way to memorialize those who had lost their lives.

Through what was undoubtedly some incredibly skillful use of contacts, Honeybee founder and MER science team member Stephen Gorevan – on a suggestion by JPL engineer Steve Kondos  and with help from the NYC mayor’s office and rover mission leader Steve Squyres – was able to procure two pieces of aluminum from the tower debris. These were fashioned into cylindrical cable shields by a contracted metal shop in Round Rock, Texas, and had American flags adhered to each by Honeybee engineer Tom Myrick.

The rovers were launched in the summer of 2003 and have both successfully operated on Mars many years past their planned initial mission timelines. Spirit currently sits silent, having ceased communication in March 2010, but Opportunity is still going strong in its exploration of the Martian surface.

“It’s gratifying knowing that a piece of the World Trade Center is up there on Mars. That shield on Mars, to me, contrasts the destructive nature of the attackers with the ingenuity and hopeful attitude of Americans.”

– Stephen Gorevan, Honeybee Robotics founder and chairman

The image above, taken in 2004, shows the cable shield with American flag on the Rock Abrasion Tool attached to Spirit.

These memorials will remain on Mars long after both rovers have ceased to run, subtle memorials to thousands of lives and testaments to our ability to forge ahead in the name of hopefulness and discovery.

Mars May Have Once Been a Cold, Wet World

Many planetary scientists suspect that Mars, now cold and very dry, once had a liquid water ocean covering parts of its surface. But this does not necessarily mean that the Red Planet was ever a tropical paradise… a recent paper by a team of astrobiologists suggests that Mars was much more bitter than balmy.

Astrobiologist Alberto Fairyn and colleagues have published a paper in the journal Nature Geoscience suggesting that the marked absence of phyllosilicates in Mars’ northern lowlands is indicative of a cold ocean environment, with perhaps even a boundary of frozen glaciers.

Phyllosilicates are minerals that, on Earth, are found readily in marine sediments and sedimentary rock that was formed in the presence of an ocean environment. These same minerals have also been seen via orbiting spacecraft spectrometers to be present in sediments located in Mars’ equatorial regions, but not in the northern latitudes. Fairyn and his team, intrigued by the disparity between existing models that described Mars as being once warm and wet and the lack of phyllosilicates in the north, used new climatic and geochemical models to deduce that Mars’ northern oceans must have been consistently near freezing, with portions even covered over by ice.

Did Mars once have ice-covered seas? (Original image © Maggie & David. Edited by J. Major.)

The current presence of moraines in the northern highlands also suggests that glaciers may have surrounded these frigid seas, which may have prevented the transportation of phyllosilicates down to the northern ocean basin. Again, to use our own planet as an analogy, moraines are rocky debris left over from the movement of glaciers. Their existence on Mars strongly suggests a period of early glaciation.

The research by Fairyn et al. contradict – or, more aptly, combine –  two leading concepts of early Mars: one, that it was cold and dry and the existence of any liquid water was restricted to the equator for small periods of time; and two, that it was once globally warmer and wetter and sustained rivers, lakes and oceans of liquid water for extended periods.

Thus a cold Mars with an Arctic, icy ocean seems to be a more fitting causation of the current state of the planet, suggests Fairyn.

More research is planned, including running through more low-temperature models and hunting for ancient coastal areas that may have been impacted by icebergs. This will no doubt prove to be a challenge since much of the evidence is now buried deep beneath newer sediments and volcanic deposits. Still, Fairyn is confident that his model may help solve a long-standing debate over the history of the Red Planet.

Shiny New Supernova Spotted in Nearby Galaxy

[/caption]

Literally an event of stellar proportions, a new Type Ia supernova has been identified in a spiral galaxy 25 million light-years away! Spotted by Caltech’s Palomar Transit Factory project, this supernova, categorized as PTF11kly, is located 58″.6 west and 270″.7 south of the center of M101. It was first seen yesterday, August 24, 2011.

According to AAVSO Special Notice #250 P. Nugent et al. reported in Astronomical Telegram #3581 that a possible Type-Ia supernova has been discovered by the Palomar Transient Factory shortly after eruption in the galaxy M101 and has been designated “PTF11kly”. The object is currently at a magnitude of 17.2, but may well rise by several magnitudes. The object is well placed within M101 for good photometry, and observations of this potential bright SNIa are strongly encouraged.

There are currently no comparison stars available in VSP for this field; please indicate clearly the comparison stars that you use for photometry when reporting observations to AAVSO. Please retain your images and/or photometry for recalibration when comparison star magnitudes are available.

Need coordinates? The (J2000) coordinates reported for the object are RA: 14:03:05.81 , Dec: +54:16:25.4. Messier 101 is located in the constellation of Ursa Major at RA: 14h 03m 12.6s Dec: +54 20′ 57″

Charts for PTF11kly may be plotted with AAVSO VSP. You should select the DSS option when plotting, as the galaxy will not appear on standard charts. This object has been assigned the name “PTF11kly” for use with AAVSO VSP and WebObs; please use this name when reporting observations until it is conclusively classified as a supernova and a proper SN name is assigned.

Type Ia supernovae are the result of a binary pair of mismatched stars, the smaller, denser one feeding on material drawn off its larger companion until it can no longer take in any more material. It then explodes in a catastrophic event that outshines the brightness of its entire galaxy! Astronomers believe that Type Ia supernovae occur in pretty much the same fashion every time and thus, being visible across vast distances, have become invaluable benchmarks for measuring distance in the Universe and gauging its rate of expansion.

The fact that this supernova was spotted literally within a day of its occurrence – visibly speaking, of course, since M101 is 25 million light-years away and thus 25 million years in our past – will be extremely handy for astronomers who will have the opportunity to study the event from beginning to end and learn more about some of the less-understood processes involved in Type Ia events.

“We caught this supernova earlier than we’ve ever discovered a supernova of this type. On Tuesday, it wasn’t there. Then, on Wednesday, boom! There it was – caught within hours of the explosion. As soon as I saw the discovery image I knew we were onto something big.”

– Andy Howell, staff scientist at Las Cumbres Observatory Global Telescope

It’s a big Universe and there are a lot of stars and therefore a lot of supernovae, but getting a chance to study one occurring so recently in a galaxy so relatively close to our own is something that is getting many astronomers very excited.

So, get those CCD camera out and best of luck!

Shedding Some Light on a Dark Discovery

[/caption]

Earlier this month astronomers released news of the darkest exoplanet ever seen: discovered in 2006, the gas giant TrES-2b reflects less than 1% of the visible light from its parent star… it’s literally darker than coal! Universe Today posted an article about this intriguing announcement on August 11, and now Dr. David Kipping of the Harvard-Smithsonian Center for Astrophysics is featuring a podcast on 365 Days of Astronomy in which he gives more detail about the dark nature of this discovery.

Listen to the podcast here.

The 365 Days of Astronomy Podcast is a project that will publish one podcast per day, for all 365 days of 2011. The podcast episodes are written, recorded and produced by people around the world.

“TrES-2b is similar in mass and radius to Jupiter but Jupiter reflects some 50% of the incident light. TrES-2b has a reflectivity less than that of any other planet or moon in the Solar System or beyond. The reflectivity is significantly less than even black acrylic paint, which makes the mind boggle as to what a clump of this planet would look like in your hand. Perhaps an appropriate nickname for the world would be Erebus, the Greek God of Darkness and Shadow. But what really is causing this planet to be so dark?”

– Dr. David Kipping

David Kipping obtained a PhD in Astrophysics from University College London earlier this year. His thesis was entitled ‘The Transits of Extrasolar Planets with Moons’ and David’s main research interest revolves around exomoons. He is just starting a Carl Sagan Fellowship at the Harvard-Smithsonian Center for Astrophysics.

The paper on which the the podcast is based can be found here.

What Lies Beneath

Collapse pit on Mars reveals opening to an underground cave

[/caption]

What would make a great home for a giant Martian ant lion? I’d have to say this pit, imaged by the HiRISE camera aboard the Mars Reconnaissance Orbiter!

Earlier this year a crater was spotted with a dark spot at its center. When the team took a closer look with the high-resolution camera they saw that the spot is actually a 35-meter (115-foot) -wide skylight that opens into an underground cavern. The cavern is most likely a section of an empty lava tube, leftovers from ancient Martian volcanic activity.

Detail of the skylight

Based on the shadows it’s estimated that the pit is about 20 meters (65 feet) deep. But, how much of that is material piled up on the floor of the cavern from the surrounding crater itself? And what caused the crater to form in the first place? These are questions that remain to be answered.

The HiRISE image itself is false-color, the hues denoting the texture and composition of the surface material and not the actual color as would be seen in visible light.

As far as a giant Martian ant lion… well, unless there are some giant Martian ants around for it to snack on, I’m going to assume there’s nobody home!

If someone were to ask you when fear was first discovered, you could tell them August 11, 1877. That’s when, 134 years ago today, Asaph Hall identified Phobos, the larger of Mars’ two moons. But even though it’s named after the Greek god of fear, there’s nothing to be afraid of…

Astronomers Discover a Dark Alien World

[/caption]

An exoplanet has been discovered by astronomers that reflects less than one percent of the light it receives from its parent star. Less reflective than black acrylic paint, this planet is literally darker than coal!

TrES-2b is a Jupiter-sized gas giant orbiting the star GSC 03549-02811, about 750 light-years away in the direction of the constellation Draco. First discovered in 2006 by the Trans-Atlantic Exoplanet Survey (TrES), its unusual darkness has been identified by researchers led by David Kipping from the Harvard-Smithsonian Center for Astrophysics (CfA) and David Spiegel from Princeton University, using data from NASA’s Kepler spacecraft.

Kepler has located more than 1,200 planetary candidates in its field of view. Additional analysis will reveal whether any other unusually dark planets lurk in that data. (Image: NASA/Kepler mission/Wendy Stenzel)

The team monitored the brightness of the TrES-2 system as the planet orbited its star and detected a subtle dimming and brightening due to the planet’s changing phase. A more reflective planet would have shown larger brightness variations as its phase changed.

The dark exoplanet is tidally locked with its star and orbits it at a distance of only 5 million kilometers (3.1 million miles), keeping it heated to a scorching 1000º C (1,832º F). Too hot for the kinds of reflective ammonia clouds seen on Jupiter, TrES-2b is wrapped in an atmosphere containing light-absorbing chemicals like vaporized sodium and potassium, or gaseous titanium oxide. Still, this does not completely explain its extremely dark appearance.

“It’s not clear what is responsible for making this planet so extraordinarily dark,” stated co-author David Spiegel of Princeton University. “However, it’s not completely pitch black. It’s so hot that it emits a faint red glow, much like a burning ember or the coils on an electric stove.”

Regardless of its faint glow TrES-2b is still much darker than any planet or moon in our solar system.

The new work appears in a paper in the journal Monthly Notices of the Royal Astronomical Society. Read the news release here.

A Noctilucent Masterpiece

Noctilucent clouds over Reykjavíc. © Örvar Atli Þorgeirsson

[/caption]

Night-shining “noctilucent” clouds create a magical glow in the night skies over Reykjavíc, Iceland in this beautiful photo by Örvar Atli Þorgeirsson, taken on August 6. In the foreground is “The Sun Voyager” (Sólfar), an iconic steel sculpture located on the city waterfront representing a Viking ship.

Örvar did not set out to photograph this rare atmospheric phenomenon but had instead intended to shoot aurora triggered by recent solar outbursts.

“The forecast on the 6th of August was predicting extreme aurora activity,” Örvar says in his Flickr description. “Even though it was very early August and the night would not get fully dark I went out as the aurora can be seen in deep twilight conditions. I saw the aurora for 1 – 2 minutes that night. I did not get a good picture of it though. Instead we witnessed this even rarer phenomenon called noctilucent clouds.”

Noctilucent clouds are extremely high-level clouds made located in the mesosphere, around 76 to 85 kilometers (47 to 53 miles) high… nearly at the very edge of space. (Most commercial airplanes fly between 6 and 7 miles high.) They are high enough to reflect sunlight coming from beyond the horizon long after night has fallen over the land below. They usually appear as a wispy web of blue, white, purple and orange tendrils stretched across the sky.

“These clouds where extremely beautiful to look at and reminded me of the aurora but where much more stationary and had this beautiful blue color.”

–  Örvar Atli Þorgeirsson

Noctilucent clouds are mainly visible at latitudes between 50º – 70º north and south during the months of June and July. This means Reykjavíc, located right in the middle, can get great views. (Of course it helps to have a talented photographer like Örvar to capture them so nicely!)

Oddly enough noctilucent clouds are a relatively recent phenomenon, only having been recorded for about 120 years. They have been connected with space shuttle passages through the upper atmosphere, and it’s even been suggested that they may be associated with the 1908 Tunguska impact.

Make iPhone Astrophotography Easier With The AstroClip!

The AstroClip™ is a simple mount that attaches your iPhone onto any telescope. Credit: Matthew Geyster.

They say necessity is the mother of invention, and if you’ve ever tried to take a picture through a telescope with your iPhone you’ll understand the necessity behind this invention: the AstroClip, an ingenious bit of injection-molded awesomeness that mounts an iPhone 4 onto any standard 1.25″ telescope eyepiece, keeping it stable and centered with the camera lens. I think this is a great idea and would certainly get one… that is, if it actually becomes a reality.

The AstroClip is designed to be very minimal while still being fully functional.

Invented by Boston designer Matthew Geyster, the AstroClip (patent pending) is still in development stage right now, awaiting the funding to go into production. Injection molding is a “simple but very expensive” process and in order to get the AstroClip produced Geyster has put his project up on Kickstarter, a web site that lets people pitch their great ideas that need funding and gives them a timeline to gather pledges.

If the AstroClip project can accumulate $15,000 in pledges by September 3, it will go into production. At the time of this writing there are 38 days left until then and it’s only 10% toward its goal. I’m hoping that drawing some more attention to this cool idea will help it along!

By becoming a “backer” you can pledge in several denomination categories, ranging from $1 or more to $500 or more. Each category above $25 comes with a “reward” of some sort… these are all listed on the project page.

I think Matthew has a great concept here. The camera on the iPhone 4 is very good and could take some great shots of the Moon and other astronomical objects, were it to just have a secure mount on a telescope lens. I’ve tried to do it without a mount before and really, it’s not easy.

Moon image taken with an iPhone and AstroClip

“The AstroClip is designed to be very minimal, while still being fully functional. The clip is very simple and rigid to hold your iPhone 4 steady and securely for the perfect shot. I also added the three adjustment screws that look like they’re meant to be on a telescope. With the simplicity and functionality of the AstroClip you will be taking great photos of outer space in no time at all.”

– Matthew Geyster

Honestly, I have no connection personally with this project or with Matthew… I just think this is something that would be very popular with iPhone users and astronomy enthusiasts. (I don’t even have a telescope… the light pollution in my city is pretty bad.) I just liked the idea so much I wanted to help support it however I could, and Universe Today seemed the perfect place to call attention to it!

If it proceeds the AstroClip will be entirely produced in the USA. Check it out on Kickstarter by clicking the image above or visit theastroclip.com.

Best of luck to a great idea!
