The Universe at a glance…

Well, several glances actually…  As spotted by the Guardian blog’s Tom McCarthy, NASA has released a new atlas and catalog of the entire infrared sky “showing more than a half billion stars, galaxies and other objects captured by the Wide-field Infrared Survey Explorer (WISE) mission.”  And an impressive view it is. [Image Credit: NASA/JPL-Caltech/UCLA]   From the Nasa press release The sky can be thought of as a sphere that surrounds us in three dimensions. To make a map of …

Stargazing, and [exo]planet hunting…

The last three nights saw the return to BBC2 of popular astronomy show Stargazing Live – presented by Brian Cox and Dara O’Briain.  Hopefully it will become, at least, an annual fixture. [Image credit: ESO/Y. Beletsky] The three hour-long programmes are still available, for now, on the iPlayer.  The entertaining ‘after-show’ shows, Back to Earth, appears to be missing are also available. If you’ve been paying attention you’ll have recognised some of the material – for example, the Lunar Reconnaissance Orbiter’s images …

Phobos-Grunt: “Re-entry is now imminent”

The BBC’s spaceman, Jonathan Amos, reports on the imminent re-entry of the 13-tonne failed Russian Mars probe, Phobos-Grunt.  Included in that 13-tonnes are more than 10 tonnes of fuel which is expected to explode when the aluminium storage tanks rupture during re-entry.  From the BBC report The Russian space agency says little of the probe will survive to the surface. It calculates no more than 200kg in maybe 20-30 fragments. Precisely where on the Earth’s surface – and when – this …

“It’ll be back in about 600 years…”

In this short video ScienceAtNasa takes an informative look at the surprisingly robust sun-grazing Comet Lovejoy. And here’s the stunning video from the crew of the International Space Station again. [Video courtesy of the Image Science & Analysis Laboratory, NASA Johnson Space Center] Pete Baker

ISS Commander: “the most amazing thing I have ever seen in space”

Having, unexpectedly, survived its solar close encounter, Comet Lovejoy is providing some spectacular views for early morning observers in the southern hemisphere.  Spaceweather has a growing collection of images. But the most spectacular view has to have been the one captured by the crew of the International Space Station (ISS).  Wow!  [Video courtesy of the Image Science & Analysis Laboratory, NASA Johnson Space Center] Usually they make do with stunning views of aurorae…  Here’s ISS Commander Dan Burbank speaking to WDIV-TV …

Kepler-22b: “This is a major milestone on the road to finding Earth’s twin”

By the time its last catalogue of exoplanet candidates was released in February,  Nasa’s Kepler space observatory, launched in March 2009, first light in April 2009, had identified 1,235 planetary candidates – and 54 candidates within the habitable zone. The Kepler team have now identified 2,326 planet candidates – of those, 207 are approximately Earth-size, 680 are super Earth-size, 1,181 are Neptune-size, 203 are Jupiter-size and 55 are larger than Jupiter.  And there are now 48 planet candidates in their star’s habitable zone There …

“Look again at that dot.”

As Curiosity heads to Mars, and Voyager continues to go boldly further than ever, the BBC reports on some speculative assessments of potentially habitable locations elsewhere in the galaxy.  A timely reminder, then, from the Guardian’s GrrlScientist of our pale blue dot in this short video tribute to Carl Sagan. Carl Sagan (1934-1996), Pale Blue Dot: A Vision of the Human Future in Space [1997: Amazon UK; Amazon US]. From this distant vantage point, the Earth might not seem of any …

Chaos on Europa

And that could be a good thing. [Image credit: Nasa/JPL. Image reprocessed by Ted Stryk].  As a BBC report notes, Nasa scientists have published their latest thinking on the chaos terrains of Jovian satellite Europa. [All hail our friend and lord, Jupiter! – Ed] *ahem*.  It suggests that the “chaos terrains form above liquid water lenses perched within the ice shell as shallow as 3 kilometres”.  Here’s a cross-section view through the surface of Europa showing the suspected “Great Lake.”  [Image credit: Britney Schmidt/Dead Pixel …
