First Analysis: the NASA Planetary Science Budget for 2014

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.

Comet PANSTARRS from the other side of the Sun!

Comet PANSTARRS is delighting northern hemisphere viewers right now. But it's also big, bright, and beautiful to the STEREO spacecraft.

Curiosity catches sunspots along with Phobos and Deimos transits
