... exoplanets . ... Extreme life-forms might be able to survive on eccentric exoplanets . Research suggests that planets potentially hostile to human life might be the perfect place for extremophiles to survive. ... Although planets like these would be very different from Earth, this might not preclude them from being able to support alien life. т??Scientists have found microscopic life-forms on Earth that can survive all kinds of extreme conditions,т?? ...

... Solar System . ... Planets . ... Until V774104 was discovered Eris (illustrated in this artist?s impression) was the most distant observed member of the Solar System. ... V774104 hardly rolls off the tongue, but this is just a provisional designation and this little world will probably receive a name eventually. ... This bleak little world was found by astronomers led by Scott Sheppard and Chad Trujillo using the 8m Subaru telescope in Hawaii and the Dark Energy Survey Camera in Chile. ...

Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

The Earth orbits the Sun with eight other planets, millions of asteroids, and perhaps trillions of comets. ... While the planets may appear to move through the night sky just as stars do, they are also moving in their own orbits around the Sun. ... When all of the planets are made, the paper clip strings should be hooked into the holes on the tops of the planets. ... The Planetary Data Table at the beginning of this chapter lists the distance of each planet from the Sun (in astronomical units). ...

... Up: Archives and Information Services . ... The VLT Archive System goals can be summarized as follows: i) record the history of VLT observations in the long term; ii) provide a research tool - make the Science Archive another VLT instrument; iii) help VLT operations to be predictable by providing traceability of instrument performance; iv) support observation preparation and analysis. ...
