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. ...

... Comet Halley's Nucleus . ... While probably formed at the same time as Io, the difference between the surfaces of these two moons of Jupiter could hardly be greater. ... In 1994, Clementine spent 70 days in lunar orbit mapping the Moon's surface. ... Red stars are cool, with temperatures of around 3,000 degrees Kelvin (K), while blue stars are hotter and can have temperatures over 30,000 degrees K. Our own lovely yellow Sun's temperature is a comforting 6,000 degrees K. Star Trails in Northern Skies...

The turret floor sits on a set of rollers bolted to the feed tower. The rolling surface sits between the bottom of the floor and the rollers. ... The plot shows the roll of the turret floor during a turret spin (.ps) ( .pdf) from 26 to 340 degrees and back (roll is in the direction of rotation). ... If there were 6 sections of rolling surface you might expect this spacing to be 60 degrees (or some beat of the 60 degree spacing and the spacing of the fixed rollers). ...

CCD Performance . ... The dark current appears to have two components: one from electronic sources in the CCD, and a second component whose strength correlates with the cosmic ray flux. ... As of this writing, the " DARKTIME" keyword in the WFPC2 image headers does not reflect correctly the actual time during which the CCD collects dark current. ... External exposures of 180s or longer made with the serial clocks off (CLOCKS=NO; the default setting) suffer an additional 60s of darktime (restart=1). ...

... Other planets also have mantles. ... From Lava Lamps to Lava Flows . The urge of the mantle to lose heat can also cause rock to bubble up toward the surface in blobs. ... Because blobs carry hot rock from the interior of the planet toward the surface, they supply volcanoes with lava. ... Convection cycles can be tens of thousands of miles tall, as they are in stars; hundreds of miles tall, as they are in planets; or just a few inches tall, as they are in tea kettles. ...

. One of the great curiosities in solar science is that our Sunт??s outer atmosphere т?? the corona т?? is heated to millions of degrees when its visible surface is "only" about 10,800ТА F (6000ТА C). Even stranger is a curious temperature minimum of 7200ТА F (4000ТА C) lying between the two layers, in the chromosphere. Now, using ESAт??s Herschel space observatory, scientists have made the first discovery of an equivalent cool layer in the atmosphere of the Sun-like star, Alpha Centauri A. // ESA
