The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Curiosity looked up after dark and captured more cool photos of Mars' moons. They include Phobos and Deimos passing in the night, and Phobos entering Mars' shadow.
IRIS, the Interface Region Imaging Spectrograph spacecraft, was launched from Orbital Science Corporation's Stargazer carrier aircraft over the Pacific Ocean at 7:27 p.m PDT.
Curiosity has been shooting photos of the Sun as Phobos and Deimos cross its face, and -- as far as I can tell -- captured sunspots as well.
Unless you are lucky and healthy enough to live for another 105 years, tomorrow will be your last chance to see a Venus transit from the surface of the Earth. But this need not be the last transit of Venus that you will ever see.
A rare astronomical event occurs June 5/6. Find out why you should care and how to observe it.
Here's a neat video posted by SungrazerComets (the Twitter identity of the U.S. Naval Research Laboratory's Sungrazing Comets website) this morning. It's an animation of images taken by the Solar and Heliospheric Observatory (SOHO) on May 13 and 14, when Jupiter was passing through solar conjunction

A new "sonification" of the recent solar storm by Robert Alexander (a University of Michigan graduate student), employing data from the MESSENGER and SOHO spacecraft.

Last night the Sun unleashed a large coronal mass ejection in our direction. Here is a compilation of images from SOHO's two LASCO cameras, plus a prediction from the new space weather prediction model that I learned about at the American Geophysical Union in December. The storm will arrive at Earth on March 8.

Before automated space observatories like SDO could send pictures and videos of solar phenomenon in real-time, humans had to do it manually, as in the case of the groundbreaking Skylab space station missions, which featured the Apollo Telescope Mount.

A report on a press briefing about Voyager 1 at the Fall 2011 American Geophyisical Union meeting. The spacecraft has entered a new region between our solar system and interstellar space, which scientists are calling the stagnation region.

I was astounded to learn this morning that SOHO can not only see Jupiter, it can actually resolve Jupiter's moons (at least its two outer ones) as points of light separate from their planet!
