The Asteroid Watch Widget tracks asteroids and comets that will make relatively close approaches to Earth. The Widget displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon); an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object. Home. Heavens-Above. ROSAT Re-entry. ROSAT (short for Röntgensatellit, in German X-rays are called Röntgenstrahlen, in honour of Wilhelm Röntgen) is a defunct German Aerospace Center-led satellite X-ray telescope, with instruments built by Germany, the UK and the US.
It was launched on 1 June 1990, on a Delta II rocket from Cape Canaveral, on what was initially designed as an 18 month mission, with provision for up to 5 years of operation. ROSAT actually operated for over 8 years, finally shutting down on 12 February 1999. ROSAT is expected to re-enter the Earth's atmosphere between October 21 and 23 2011. In February 2011, it was reported that the 2,400 kg satellite was unlikely to burn up entirely while re-entering the earth atmosphere due to the large amount of ceramics and glass used in construction. Parts as heavy as 400 kg could impact the surface intact. (from Wikipedia) Links "Live" Stats Guide to viewing ROSAT in Orbit Re-Entry Predictions Who does this?

UKIDSS Galactic Plane Survey (GPS) Mosaic - DR7 The main window below displays a 6 billion pixel (1 arcsec pixels) mosaic of the GPS (centre: l=52, b=0 (109 > l > 0 ,360 > l > 355 and -2.5 < b < +2.5). Use the controls in the main window or the mouse (click&drag ) to move around the image and zoom in and out. Click on the small images on the left to move to that point in the mosaic.
