A very interesting comet has recently been discovered -- interesting because it will nearly graze the Sun in August 2013 and then approach Earth closely the following December. Whether it will turn out to be a great comet is impossible to know.

I'm hosting this week's Cosmoquest Science Hour, and plan to take viewers on a virtual tour of those mountains on Curiosity's horizon, and show you where Curiosity is likely to go. Join me and Fraser Cain here at 1600 PDT / 2300 UTC Wednesday.

The Planetary Society Shoemaker NEO grants celebrate their 15th anniversary of helping to find and track near Earth asteroids. Here's a quick review of the program, and updates on our four multiple-grant winners.

An amateur-processed mosaic of some intriguing-looking broken rocks along Curiosity's traverse. They were intriguing enough to photograph with the Mastcam -- but not enough to stop and check them out, as Curiosity has already rolled on.

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

Oppy is opening an exciting new chapter in her adventure at Cape York. Having driven down to, over and past Whim Creek, she has now explored halfway down Cape York, to a promising fin-like ridge of dark rock.

Curiosity's much-anticipated self-portrait with the MAHLI camera just arrived on Earth, and even though it was shot through the dust cover it is AWESOME.

I noticed today that I hadn't seen any amateur-processed versions of Voyager's departing shots of Uranus, so I decided to give it a try.

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.

After more than a year in orbit, Dawn has left Vesta, beginning the spacecraft's journey to Ceres.

OSIRIS-REx is will return a piece of the ancient asteroid 1999 RQ36, and it's up to you to come up with a name.

It was a surprise and delight to have our Icarus paper highlighted in Emily Lakdawalla's blog. Thanks for highlighting Uranus, since it has gotten, ahem, a bum rap over the years. Here's more about our discovery of the dark spot on Uranus.

HiRISE's best opportunity to view Curiosity so far came 12 days after landing, when the orbiter passed nearly directly overhead. The photo resolves amazing detail on the huge rover.

Although Neil Armstrong may have passed away, his name will be part of human history forever.
