Direct Electron Imaging Using Back Thinned CCDs . EBCCD Principles . Back-illuminated CCDs are sensitive to kilovolt-energy electrons incident on the back surface through the EBS gain process. ... Backside enhancement techniques such as UV charging, ion implanting, and annealing and flash gate technologies are designed to reverse the field near the surface so that electrons generated there are repelled and collected in the CCD well. ... Cross-sectional drawing of a proximity focused EBCCD. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... STScI-PRC97-32 HUBBLE SEES A NEUTRON STAR ALONE IN SPACE This is the first direct look, in visible light, at a lone neutron star, as seen by NASA's Hubble Space Telescope. The Hubble results show the star is very hot (1.2 million degrees Fahrenheit at the surface), and can be no larger than 16.8 miles (28 kilometers) across. These results prove that the object must be a neutron star, because no other known type of object can be this hot, small, and dim (below 25th magnitude). ...

... 2000 October 2 . Pangea Ultima: Earth in 250 Million Years? ... The surface of the Earth is broken up into several large plates that are slowly shifting. About 250 million years ago, the plates on which the present-day continents rest were positioned quite differently , so that all the landmasses were clustered together in one supercontinent now dubbed Pangea . About 250 million years from now, the plates are again projected to reposition themselves so that a single landmass dominates. ...

USSR Venus Orbiters . ... Venera 15 and Venera 16 were a two-spacecraft mission designed to use 8-centimeter (3-inch) band, side-looking radar mappers to study the surface properties of Venus . ... Each spacecraft consisted of a synthetic aperture radar (SAR) and a radio altimeter. ... The Venera 15 and 16 synthetic aperture radar (SAR) systems were identical, and were used to map the surface of Venus at a resolution of 1 to 2 kilometers (.6 to 1.2 miles) over a period of 8 months. ...

Mal Ruderman (KIPAC, Stanford) . What do we see when we look at the surface of a neutron star from a great distance? ... The new point that is made is a consequence of near-relativistic electron-positron flows expected in the near-magnetosphere's of "young" (not older than about a million years) neutron stars. Because of cyclotron resonance scattering by these pair-flows on surface X-ray and UV emission, we do not see unprocessed suface emission. ...

Villains and Heroes of Lights and Lighting Fixtures . If we are to reduce the effects of light pollution, we must learn about the types, both good and bad, of fixtures used in outdoor lighting. ... In fact, this type of fixture is often chosen for this very reason. ... Although these lamps are not very energy efficient, and they are often found in older, inefficient fixtures that enhance light pollution, they still exist in great abundance in most locations and are still sold by the millions. ...
