The astronomy world is all a-twitter this morning over the discovery of a new supernova in M82, a galaxy that's in our astronomical backyard, "only" 12 million light-years away. And early word is that it appears to be a Type Ia supernova, the kind that's used as a standard candle to measure the expansion of the universe.
Planetary Radio: The Gemini Planet Imager
Featuring GPI PI Bruce Macintosh and Astronomer Franck Marchis
It's very nice to infer the existence of planets circling other stars. It's even better to see them. This new instrument has just become the most powerful exoplanet viewer yet created.
Can features on Neptune be observed by amateur astronomers? For years, the Hubble Space Telescope and some professional terrestrial observatories have been revealing incomplete belts and spots on the surface of Neptune. Now, spots have been imaged by amateurs.

You may have noticed that Comet ISON appears to have a green halo in some recent images, but in other images acquired at about the same time, it doesn’t. Thanks to the beautiful new spectrum posted earlier today by Christian Buil, it’s relatively easy to understand why.
It’s been a long time since anyone paid Uranus a visit. The Uranus system is, however, fascinating, as evidenced by the wealth of topics covered by the diverse group of planetary scientists who gathered to discuss it last week at the Paris Observatory.

The Planetary Society Optical SETI (OSETI) Telescope was successfully upgraded and fully tested, and is now fully operational looking for aliens. Here are some updates on the performance and progress. In summary, the upgraded telescope is performing just as hoped and is scanning the skies.

The world's great telescopes capture stunning photographs of stars, nebulae, and other sky phenomena. In Europe to the Stars, authors Govert Schilling and Lars Lindberg Christensen share many such photos. But the real stars of this book are the great telescopes of the European Southern Observatory.
For several weeks now, ground-based observers have been blind to Comet ISON as our local star was sitting directly between us and the comet. I am delighted to share two pieces of good news: first, that ISON is still alive and well, and secondly that it has been recovered.
Planetary Society Hangout: Arkyd Telescopes, Planetary Resources, Chris Lewicki

We talked to Chris Lewicki, President of Planetary Resources, about their upcoming Arkyd telescopes including one for the public, asteroid mining, and more. Hosted by Bruce Betts with Jennifer Vaughn.
Astronomy Enters a New Era
Join us for a live webcast about thrilling new tools that will come online in the next decade.
A live conversation about just a few of the powerful new instruments that will revolutionize our knowledge of the cosmos once again.
Ever wonder what it would taste like if you could lick the icy surface of Jupiter’s Europa? The answer may be that it would taste a lot like that last mouthful of water that you accidentally drank when you were swimming at the beach on your last vacation.
Emily Lakdawalla's guest this week was Applied Physics Laboratory asteroid astronomer Andy Rivkin. We talked about the menagerie of rocks in the asteroid belt, how many of them travel in pairs and triples, how some of them are surprisingly wet, and how much you can learn about asteroids using Earth-based telescopes.
Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.
My solar system chauvinism is well-established, but I am as much a sucker for beautiful astrophotos as the rest of you. Once in a while I get a media advisory from the European Southern Observatory about a new pretty picture posted on their website, and then I inevitably lose an hour following links to one stunner after another.
