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.

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!

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

According to a press release issued this morning by the National Oceanic and Atmospheric Administration, the enormous solar flare that erupted on December 5 and 6 last year was accompanied by an intense radio burst that caused large numbers of Global Positioning System recivers to stop tracking the signal from the orbiting GPS satellites.
