The insets in the black boxes show close-ups of some of the structures that lava can form: (left) branched channels, (middle) a snaking channel and (right) rootless vents; the rootless vents are also marked by yellow spots on the main image.

Images of Mars taken from orbit show a massive system of riverbeds and canyons etched by water. Or maybe not. A new study of one channel shows that it was formed by lava flow and not water, and the results make "a strong case that fluid lava can produce channels that look very much like water-generated features," said Jim Zimbelman from the Smithsonian Institution in Washington, one of the researchers. "So, we should not jump to a water-related conclusion when we see such channels on other planets."

As with last week's Universe Puzzle, something that cannot be answered by five minutes spent googling, a puzzle that requires you to cudgel your brains a bit, and do some lateral thinking. This is a puzzle on a "Universal" topic – astronomy and astronomers; space, satellites, missions, and astronauts; planets, moons, telescopes, and so on.

What's the next number in the sequence?

NGC 4490/4485 – T. Grossman, D. Hager and R. Johnson

Way out yonder some 40 to 50 million light years away in the constellation of Canes Venetici is a pair of interacting galaxies sometimes referred to as "The Cocoon". These two mis-shaped blobs of star stuff have already made their closest approach to each other and are now parting ways. Between them stretches a trail of stars that spans some 24,000 light years as they face each other showing off their numerous star-forming regions. But where there is life… There is death. Let's put our finger right on the pulse of a supernova. (...)

Classify this one under the same nonsense as the "Bigfoot on Mars" the wooden plank on Mars, or perhaps even the "Face on Mars." Just an optical illusions, folks from a very, very zoomed in image from the Mars rovers. The Sun newspaper seemingly started this foolishness on what must have been a slow news day.

Several news sources reported Thursday that NASA Administrator Charlie Bolden had asked senior managers to come up with an alternate plan for the newly proposed NASA budget after members of Congress indicated they wanted to reject a White House proposal to cancel the Constellation program and hire private companies to bring astronauts to the ISS. But today, Bolden issued a memo saying there is no "Plan B" and that he only asked two agency directors to help develop an accelerated plan for research and development on a heavy lift launch vehicle. The lack of heavy lift capability is one of the big sticking points for many on the new plan.

"I have not asked anyone to develop an alternative to that budget and plan," Bolden wrote, "and I don't want anybody to do so. Rather, I have asked – and am asking – for input on how the exceptional talents and capabilities we have developed in our organization can best be applied going forward to advance the elements of our new plan."

Back in the 1950s and 1960s, there was some speculation that Mars' moon Phobos could possibly be hollow due to the its unusual orbital characteristics. While scientists now agree that the moon is very likely not hollow, vast caverns may exist within the moon, and it might be a porous body instead of solid. The Mars Express spacecraft made a close flyby of Phobos on Wednesday to help provide more data on the interior of Phobos, and all indications are the event was a big success. The spacecraft skimmed smoothly over the odd-shaped moon at just 67 km, the closest any manmade object has ever been. No images were taken from this flyby. Instead all the instruments were turned off so that ground stations could listen for a pure radio signal of how Phobos "tugged" on the spacecraft. Scientists say the data collected could help unlock the origin of Phobos and other ‘second generation’ moons.

Hi, this is Nancy Atkinson from Universe Today. Right now I'm at Kennedy Space Center, and I've had the opportunity to see a couple of launches and cover other events that normally, I'd be back home watching on NASA TV. Since NASA TV is part of my daily diet of space media, I was very interested to see the newsroom, step in the auditorium where all the press conferences are held, and also talk with some of the people who work at NASA TV at Kennedy Space Center, or KSC TV as they call it, to find out about the work that they do, and also what it's like to provide some of the most unique and exciting coverage anywhere on — and off — the planet. I chatted with producers, directors, technicians and other people who work behind the scenes, plus I also had the good fortune to talk with one of the voices of NASA TV, George Diller.

Here are some of our conversations.

GOES-P launches from Kennedy Space Center. Image Credit: Alan Walters (awaltersphoto.com) for Universe Today.

A Delta IV rocket rumbled and roared off launch pad 37B at Cape Canaveral Air Force Station in Florida Thursday evening, sending the GOES-P satellite soaring into a crisp and clear night sky. With liftoff at 6:57 p.m. EST, the rocket could be seen for several minutes after launch, and booster separation was clearly visible to observers on the NASA Causeway. The Geostationary Operational Environmental Satellite-P, or GOES-P, is the latest in a series of meteorological satellites designed to watch for storm development and weather conditions on Earth as well as detect hazards with its emergency beacon support and Search and Rescue Transponder. It will take ten days for the satellite to maneuver to its geostationary equatorial orbit at 35,888 km (22,300 miles). Once there, GOES-P will get a new name: GOES-15.

Over the years, scientists have debated the cause of the mass extinction that wiped out the dinosaurs 65 million years ago. Now, a panel of 41 international experts says it's official: a massive asteroid around 15 kilometers wide slamming into Earth at Chicxulub, Mexico is the culprit. After surveying a wide variety of evidence for the competing theories, the panel said the telling evidence was the structures preserved in the interior of the crater. Computer models predicted how much rock was vaporized or ejected by the impact. "Our work lets us visualize the astonishing events of the few minutes after impact," said Dr. Penny Barton, who led the group. "The front of the asteroid hit the Earth while the far side was still out in the upper atmosphere, punching a hole though the Earth's atmosphere."

The Goddard Space Flight Center has a Flickr account showcasing a series of images of our own home planet. Called "Blue Marble," these spectacular images are the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations in 2001 of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. Your tax dollars at work, these images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.

Mosaic of microscopic images of Spirit underbelly on Sol 1925 (June 2009) showing the predicament of being stuck at Troy with wheels buried in the sulfate-rich martian soil. The sulfate deposits formed by aqueous (water-related) processes when this area dubbed “Home Plate’ was volcanically active. This false color mosaic has been enhanced and stretched to bring out additional details about the surrounding terrain and embedded wheels and distinctly show a pointy rock perhaps in contact with the underbelly. Spirit fortuitously discovered extensive new evidence for an environment of flowing liquid water at this location on Mars adjacent to ‘Home Plate’, an eroded over volcanic feature.

The plucky Mars rover ‘Spirit’ may yet rove again !

She’ll just have to outwit and outlast the unavoidably harsh cold and desperately low power levels of the looming winter in Mars southern hemisphere. Rather long odds to be sure – but she’s done it before. Remember – at this moment on Sol 2192, Spirit is 75 months into her 3 month mission ! That’s 25 times beyond her “warrenty” as Rover Principal Investigator Prof. Steve Squyres of Cornell University is extremely fond of saying. (...)

Here's another Where In The Universe Challenge, to test your visual knowledge of the cosmos. This week's image was submitted by UT reader Jason Major, who is hoping this one will pose a challenge for everyone. But 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 instrument responsible for the image. We’ll provide the image today, but won’t reveal the answer until tomorrow. 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.

Good Luck!

UPDATE: The answer is now below.

A newly discovered red giant star is a relic from the early universe — a star that may have been among the second generation of stars to form after the Big Bang. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star has a remarkably similar chemical make-up to the Milky Way’s oldest stars. Its presence supports the theory that our galaxy underwent a “cannibal” phase, growing to its current size by swallowing dwarf galaxies and other galactic building blocks.
