Here’s this week’s image for the Where In The Universe Challenge, to test your visual knowledge of the cosmos. You know what to do: take a look at this image and see if you can determine where in the universe this image is from; give yourself extra points if you can name the spacecraft/telescope responsible for the image. We’ll provide the image today, but won’t reveal the answer until later. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.
UPDATE: The answer has now been posted below!
Ah, its springtime on Mars’ southern hemisphere! This is Mars, as seen by the HiRISE camera on the Mars Reconnaissance Orbiter. Specifically, this is a “spot” near the south pole of Mars (-84.3 degrees latitude and 242.1 degrees east longitude) called the Starfish region. MRO is monitoring how warmer weather is changing the polar landscape.
Just try to keep up with internet vlogger Hank Green of Vlogbrothers as he explains why he believes NASA is worth every .45 penny of any American’s hard-earned US tax dollar. And believe it or not, this is a video from NASA Television. They really are increasing the awesome.

The Zooites working at the Moon Zoo citizen science project have uncovered some very unique oblique views of the Moon taken by the Lunar Reconnaissance Orbiter. Occasionally, LRO takes “sideways glances” at the Moon instead of looking straight down like the spacecraft normally does. The Moon doesn’t really look like this close up, because these images aren’t scaled correctly (the width and height pixel scales are different by five times, the Zooites say in the Moon Zoo Forum), but they provide a distinctive look at the lunar surface, and things like craters on the side of a hill, — or perhaps an entrance to a cave — show up better than in normal images. Have fun looking at some more of these images below, or on the Moon Zoo Forum.

Andromeda is a beautiful galaxy to see with your own eyes, but in this video, ESA’s fleet of space telescopes — XMM Newton, Herschel, Planck and several ground-based telescopes — has captured M31, in different wavelengths, most of which are invisible to the eye. Each wavelength shows a different aspect of the galaxy’s nature, as well as providing a look at the lifecycle of the stars that make up Andromeda.

What makes a star go boom? A new look at Tycho’s supernova remnant by the Chandra X-ray telescope has supplied astronomers with previously unseen evidence for what could trigger specific type of supernova, a Type Ia supernova explosion. Astronomers have spotted what appears to be material that was blasted off a companion star to a white dwarf when it exploded, creating the supernova seen by Danish astronomer Tycho Brahe in 1572. There is also evidence that this material blocked the explosion debris, creating an “arc” and a “shadow” in the supernova remnant.
There are two main types of supernovae. One is where a massive star – much bigger than our sun — burns all its nuclear fuel and collapses in on itself, which ignites a supernova explosion. Type Ia supernovae, however, are different. Smaller stars eventually turn into white dwarfs at the end of their lives, becoming an ultra-dense ball of carbon and oxygen about the size of the Earth, with the mass of our Sun. In some instances, though, a white dwarf somehow ignites, creating an explosion so bright that it can be seen billions of light years away, across much of the Universe. But astronomers really haven’t understood what causes these explosions to start.
There are a couple of popular theories: one scenario for Type Ia supernovas involves the merger of two white dwarfs. In this case, no companion star or evidence for material blasted off a companion should exist. In the other theory, a white dwarf pulls material from a “normal,” or Sun-like, companion star until a thermonuclear explosion occurs.
Both scenarios may actually occur under different conditions, but the latest Chandra result from Tycho supports the latter one.

The new Chandra images show the famous leftovers of Tycho’s supernova, and reveal for the first time an arc of X-ray emission within the supernova remnant. The shape of the arc is different from any other feature seen in the remnant. This supports the conclusion that a shock wave created the arc when a white dwarf exploded and blew material off the surface of a nearby companion star.
In addition, this new study seems to show how resilient some stars can be, as the supernova explosion appears to have blasted very little material off the companion star. Previously, studies with optical telescopes have revealed a star within the remnant that is moving much more quickly than its neighbors, hinting that it could be the missing companion.
“It looks like this companion star was right next to an extremely powerful explosion and it survived relatively unscathed,” said Q. Daniel Wang of the University of Massachusetts in Amherst, a member of the research team whose paper will appear in the May 1st issue of The Astrophysical Journal. “Presumably it was also given a kick when the explosion occurred. Together with the orbital velocity, this kick makes the companion now travel rapidly across space.”
This image shows iron debris in Tycho's supernova remnant. The site of the supernova explosion is shown, as inferred from the motion of the possible companion to the exploded white dwarf. The position of material stripped off the companion star by the explosion, and forming an X-ray arc, is shown by the white dotted line. This structure is most easily seen in an image showing X-rays from the arc's shock wave. Finally, the arc has blocked debris from the explosion creating a "shadow" in the debris between the red dotted lines, extending from the arc to the edge of the remnant.

Using the properties of the X-ray arc and the candidate stellar companion, the team determined the orbital period and separation between the two stars in the binary system before the explosion. The period was estimated to be about 5 days, and the separation was only about a millionth of a light-year, or less than a tenth the distance between the Sun and the Earth. In comparison, the remnant itself is about 20 light-years across.
Other details of the arc support the idea that it was blasted away from the companion star. For example, the X-ray emission of the remnant shows an apparent “shadow” next to the arc, consistent with the blocking of debris from the explosion by the expanding cone of material stripped from the companion.
“This stripped stellar material was the missing piece of the puzzle for arguing that Tycho’s supernova was triggered in a binary with a normal stellar companion,” said Fangjun Lu of the Institute of High Energy Physics, Chinese Academy of Sciences in Beijing. “We now seem to have found this piece.”
Because Type Ia supernova are all of similar brightness, they are used as a standard candle to measure the expansion of the Universe, and this new observation by Chandra has helped to answer at least part of the long-standing – and critical — question of what triggers these bright explosions.
Several student experiments will travel with the more famous Alpha Magnetic Spectrometer-02 on the shuttle Endeavour. Image Credit: NASA.gov
[/caption]CAPE CANAVERAL – STS-134, the final flight of the space shuttle Endeavour – is set to carry several experiments of students from the middle school, high school and collegiate levels. Two of these payloads are sponsored by the NASA Florida Space Grant Consortium.
The first experiment is one that could provide some guidance on future long-duration space flight missions, it deals with seed germination. As missions take astronauts further and further away from Earth, they will need to be able to produce their own food. Learning everything possible about the effects of micro-gravity on seeds therefore is viewed as relevant and important research.

“Crystal Lake Middle Schools’ students and staff members are grateful that the Florida Space Grant Consortium has provided funding that will allow one of our student experiments to fly aboard the Space Shuttle Endeavour in low Earth orbit for 14 days,” said the Magnet Programs Coordinator for Crystal Lake Middle School, Lenecia McCrary. “The students entered a school-wide competition that involved proposing and designing real and practical experiments. The chosen experiment deals with investigating the effects of micro-gravity on apple seed germination.”
A little higher up on the educational ladder is the STEM Bar experiment being flown on STS-134. High school students Mikayla and Shannon Diesch won the 2010 Conrad Foundation Spirit of Innovation Award and will be at the launch watching as Endeavour takes their newly developed STEM Bar to the International Space Station. The STEM Bar was developed using NASA’s food safety standards and certified to fly on STS-134.
Another experiment, one comprised of squid embryos is being spearheaded by the University of Florida and will research the physiological impact of the micro-gravity environment on the animal’s growth and development.
“The Squids in Space project is a cohesive effort in which the full range of NASA Florida Space Grant Consortium supported categories work together on an experiment destined to fly on what will be the last flight of space shuttle Endeavour,” said Florida Space Grant Consortium Director Jaydeep Mukherjee. “This team, which is composed of Florida colleges and high school students and led by University of Florida PhD research scientist Jamie Foster, will connect the three tiers of education in an experiment studying the effects of microgravity on squid embryos.”

The inclusion of these student experiments on board Endeavour is viewed by those sponsoring and supporting these student-led experiments as evidence of NASA’s commitment to educational outreach. NASA has to maximize every square inch of space on the orbiters to stock up the space station for the post-shuttle era. As such, clearing room for these experiments highlights is viewed as an expression of the high value that the space agency places on education. After the launch of Endeavour only a single shuttle flight remains in the program, STS-135 which is slated for liftoff on June 28 on space shuttle Atlantis.

On April 29th, 2011, the space shuttle Endeavour is scheduled to blast off for the last time, delivering the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station.
If you live in the UK you can watch the launch live on NASA TV and a number of other sites on the internet, but that’s not all you can do! You may be able to watch it fly over the UK with your very own eyes about 20 minutes later!
Yes! You can watch the Shuttle fly over the UK roughly 20 minutes after launch (launch time is currently set for 3:47 p.m. EDT – 8:47 p.m. UK Time) if the timing is right and skies are clear. It will be accompanied by its bright orange external fuel tank as it sails across the sky.
I was lucky to see and actually film this in August 2009 with the launch of STS-128 Space Shuttle Discovery.
How to see it? Go outside roughly 15 – 20 minutes after launch and you could see two bright objects similar to what the ISS looks like when it passes over, moving at roughly the same speed. These bright objects in parallel to each other will follow a similar track in the sky to what the ISS does, but it will be the Shuttle Endeavour and its separated external fuel tank!
Hope for clear skies and that the launch isn’t delayed, as this may be our last chance ever of seeing a space shuttle fly over the UK just after launch.

KENNEDY SPACE CENTER – The six man crew for Shuttle Endeavour’s final flight to space arrived today (April 26) at the Kennedy Space Center in Florida. The crew flew in to the Shuttle Landing Facility (SLF) on a quartet of T-38 jets from their training base in Houston.
Shuttle Commander Mark Kelly introduced his crew to a large crowd of gathered reporters, photographers and NASA officials including Launch Director Mike Leinbach, KSC Director Bob Cabana and Kelly’s twin brother Scott who recently returned from a six month stint aboard the International Space Station.

Speaking on behalf of the entire crew he said, “We’re really happy to be here today,” said Kelly. “We got a chance to take look at the orbiter as we first flew over the field and then the over pad. It’s great to see Endeavour all ready to go again.”
Kelly was exuberant in saying that his wife, Congresswoman Gabrielle Giffords, was well enough to attend the STS-134 launch set for Friday, at 3:47 p.m. EDT.
The shuttle launch countdown officially commenced at 2 PM today. The weather outlook is 80% GO, with a 20% chance of weather violations prohibiting launch according to Shuttle weather officer Kathy Winters.

STS-134 is the 25th and final launch of Space Shuttle Endeavour.
The primary payload aboard Endeavour is the $2 Billion Alpha Magnetic Spectrometer (AMS) ) which the crew will attach to the International Space Station. The AMS will collect cosmic rays, search for dark energy, dark matter and anti matter and seeks to determine the origin of the Universe.
