A quarter moon is visible in this oblique view of Earth's horizon and airglow, recorded with a digital still camera on the final mission of the Space Shuttle Columbia. Columbia's crew was killed on Feb. 1, 2003 when the shuttle broke up on re-entry into Earth's atmosphere.
Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805, is visible in the above right. The above image was taken in infrared light by the recently launched WISE telescope.
Perseid meteor shower tonight is at its peak. It's the only meteor shower known to have killed a satellite and delayed a space-shuttle launch. Enter the Meteoroid Environment Office.
On August 1, almost the entire Earth-facing side of the sun erupted in a tumult of activity. This image from the Solar Dynamics Observatory shows the C3-class solar flare (white area on upper left), a solar tsunami (wave-like structure, upper right), multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more.
