Ever since I first learned about the capabilities of Mars Orbiter Mission's small payload of science instruments, I have been anticipating one type of data in particular: global color views of Mars captured in a single 2000-pixel-square frame. Just days after entering orbit, Mars Orbiter Mission has delivered on that promise.
Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.

Hubble has taken some great new images of our 'friend,' Comet Siding Spring, due to pass by Mars at less than 136,000 km on October 19 – less than half the distance between Earth and our moon.
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 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!
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.
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.

In an enthralling article for Esquire magazine, astronaut Mike Massimino writes about nearly failing to repair the Hubble Space Telescope, and how the people of Earth came to his rescue.
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
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.
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?
Last week, I posted an explainer on why Hubble's images of galaxies show so much more detail than its images of Pluto. Then I set you all a homework problem: when will New Horizons be able to see Pluto better than Hubble does? Here's the answer.
