Destination: Europa!

It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!

The Plumes of Europa

2013 has been a rather exciting year for Europa scientists. Today's exciting news: the Hubble Space Telescope discovery of water vapor plumes from the south pole of this icy moon.

Neptune: The new amateur boundary?

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.

Uranus Awaits

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.

Lesser-known views of Uranus and Neptune

Despite the fact that Voyager 2 returned relatively few high-resolution images from either Uranus or Neptune, there are many more photos in the archives than regularly make it to public view.

Astronomy Enters a New Era

A live conversation about just a few of the powerful new instruments that will revolutionize our knowledge of the cosmos once again.

Planetary Society Weekly Hangout: The Ice Giants, with Heidi Hammel

My guest this was Planetary Society Board vice president Heidi Hammel. We discussed two planets near and dear to our hearts, Neptune and Uranus. What's new on these icy worlds since Voyager 2 passed by, and what are the prospects for their future exploration?

Crowdsourcing the Andromeda Galaxy

Scientists would like your help starting at high-resolution images of the Andromeda Galaxy captured by the Hubble Space Telescope.

New spots on Uranus

New Hubble photos show that Uranus has both dark and bright spots!

Salacia: As big as Ceres, but much farther away

A newly published paper shows trans-Neptunian object Salacia to be unexpectedly large; it's somewhere around the tenth largest known thing beyond Neptune. It has a companion one-third its size, making it appear similar to Orcus and Vanth.

More Venus transits in 2012

A transit of Venus as seen from Jupiter may be observed by Hubble on September 20 and a transit of Venus as seen from Saturn will be observed by Cassini on December 21.

NRO gives NASA two hand-me-down telescopes

The National Reconnaissance Office has donated two, partially-completed space telescopes to NASA, revealed at a National Academies' Committee on Astronomy and Astrophysics meeting this week.
