Did you ever see a comet plunge into the sun? Not likely unless you have seen images from the Solar and Heliospheric Observatory (SOHO). Watch as the comet strikes the heliosphere and causes a solar explosion.

Yesterday, the Solar and Heliospheric Observatory (SOHO) caught a comet plunging toward the sun. It went in–but not out again. The sungrazing comet disintegrated like an ice cube in an oven.
In the animation, the white circle represents the outline of the sun. The dark circle is a shield in the optics to block the solar image so background activity and objects may be seen. Above and to the left is the planet Venus which just passed above and in front of the Sun. In a wider field of view image, the planet Mars can also be seen along with labels explaining the image.
ECLSS in Iraq — Since April 2006, an Earth-bound application of a portion of the ECLSS water recovery system is being trucked from one rural village to another in northern Iraq to filter particulates and contaminants out of dirty groundwater or well water to provide residents with clean drinking water. That portable system—about half the size of a refrigerator including all its pumps and computer controls—purifies water at a good clip of 4 gallons a minute, for a cost of only about two cents a gallon.
The twin spacecraft mission STEREO blasted off from Cape Canaveral in a nighttime launch last night. STEREO, which stands for Solar TErrestrial RElations Observatory, is a two-spacecraft mission to observe solar activity from two vantage points in orbit around the sun. the spacecraft, identified as A (ahead) and B (behind), will head for the Moon to get a gravitational “slingshot” into orbit. B will be flung into orbit behind the Earth while A will return to the Moon for another boost into orbit ahead of Earth. This separation in space provides a unique view of the Sun from orbits with a similar distance from the Sun as the Earth, while imaging from points away from our planet. The spacecraft will assume their stations near 
Though it’s 93 million miles away, the Sun still hurts your eyes when you look at it. But bright sunlight (along with accurate planning and proper equipment!) resulted in this sharp silhouette of spaceship and space station. The amazing telescopic view, recorded on September 17, captures shuttle orbiter Atlantis and the International Space Station in orbit over planet Earth. At a range of 550 kilometers from the observing site near Mamers, Normandy, France, Atlantis (left) has just undocked and moved about 200 meters away from the space station. 
The Mission Control Center in Houston informed the STS-115 crew about 10:45 a.m. EDT that Wednesday’s landing attempts have been waved off due to an unfavorable weather forecast, coupled with the possibility of additional inspections of Space Shuttle Atlantis.
