A 0.81m telescope in northern Italy is well on its way to being wide eyed and shiny thanks to a 2013 Planetary Society Shoemaker NEO Grant, which will enable it to make better near Earth object observations to help protect our planet from asteroid impact.

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.

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.

A short film on the Giant Magellan Telescope, which could revolutionize exoplanet research and shape the search for life in the Universe.
A case of the measles for Jupiter?

Amateur astronomer Christopher Go has found Jupiter to be putting on a fun show for observers: it's sprouting little red spots "like it has a measles attack!"
Neptune: The new amateur boundary?
Posted by Christophe Pellier on 2013/11/07 05:39 CST | 3 comments
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.

A video on the Giant Magellan Telescope and its third mirror, which was cast on August 24, 2013 at the University of Arizona's Steward Observatory Mirror Lab in Tucson, Ariz.
Book review: Europe to the Stars, by Govert Schilling and Lars Lindberg Christensen
Posted by Emily Lakdawalla on 2013/08/16 11:05 CDT
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.
Comet ISON lives on! (we think...)
Posted by Karl Battams on 2013/08/13 01:31 CDT | 1 comments
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.

We don't have any spacecraft at Jupiter right now, which is a pity. Until we do, we have to rely upon Earth-based astronomers to monitor the changing face of the largest planet.

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.
Planetary Society Weekly Hangout: Studying Asteroids from Earth with Andy Rivkin
Posted by Emily Lakdawalla on 2013/02/28 01:25 CST | 5 comments
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.
