In this x-ray photo provided by NASA, the sun is shown early in the morning of Aug. 1. The dark arc near the top right edge of the image is a filament of plasma blasting off the surface - part of the coronal mass ejection. The bright region is an unassociated solar flare. When particles from the eruption reach Earth on the evening of Aug. 3-4, they may trigger a brilliant auroral display known as the Northern Lights.
This photo, captured by the NASA Hubble Space Telescope's Advanced Camera for Surveys, is Hubble's latest view of an expanding halo of light around the distant star V838 Monocerotis, or V Mon, caused by an unusual stellar outburst that occurred back in January 2002. A burst of light from the bizarre star is spreading into space and reflecting off of surrounding circumstellar dust. As different parts are sequentially illuminated, the appearance of the dust changes. This effect is referred to as a "light echo".
Space shuttle layoffs, effective Oct. 1, involve 902 workers in Florida, 478 in Texas and 14 in Alabama.
Recent reports have accused the US military of irresponsible disposal of millions of pounds of hazardous waste, mostly from the Iraq war. But after investigating, the military says EPA standards are being upheld.
Astronomers have long warned of a nasty encounter with a large space rock, but don't worry: There's a proposal in Congress to establish a commission to look into it.
This majestic view taken by NASA's Spitzer Space Telescope tells an untold story of life and death in the Eagle nebula, an industrious star-making factory located 7,000 light-years away in the Serpens constellation. The image shows the region's entire network of turbulent clouds and newborn stars in infrared light. The color green denotes cooler towers and fields of dust. Red represents hotter dust thought to have been warmed by the explosion of a massive star about 8,000 to 9,000 years ago.
In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. This image taken by the CFHT's new MegaPrime camera shows the region in unprecedented detail. Although the emission nebula is dominated by red hydrogen light, the above image has exaggerated the effect of green light emitted primarily by small amounts of oxygen .
A setting sun and Earth's horizon are featured in this image photographed by an Expedition 13 crewmember on the International Space Station in 2006.
If you've got an adventurous spirit and a fat bank balance, these out-of-this-world holidays are for you.
This image courtesy of the European Southern Observatory (ESO) shows an artist's impression of an active galaxy that has jets. The central engine is thought to be a supermassive black hole surrounded by an accretion disc and enshrouded in a thick doughnut-shaped structure of gas and dust, which astronomers call a "torus". The torus of dust and gas can be seen orbiting a flatter disc of swirling gas. In the center, the supermassive black hole is surrounded by a flat accretion disc of rapidly orbiting material. The jets are emitted at right angles from the plane of the disc.
