Detection of the YORP Effect from Photometric Observations of Near-Earth Asteroids . ... In this report we present summary of photometric observations of near-Earth asteroids (NEAs) obtained to search for YORP effect. ... Observations of 1620 Geographos in 2008 and 3103 Eger in 2009 are used to detect the acceleration of the asteroids rotation rates in agreement with the computed theoretical values due to YORP effect. Now there are four asteroids with the YORP effect detected. ...

. The degenerate gas is the quantum gas at the temperature below the degenerate temperature Td. In the idea degenerate gas bosons Bose-Einstein condensation is coming. Degeneration occures when the wave lengh de Brole (the energy of the heat particles motion) becomes nearly the same as the distance between them. The electrons gas in metals is always degenerated gas. Back .

... Fermi catches thunderstorms hurling antimatter into space . Scientists think the antimatter particles formed in a terrestrial gamma-ray flash, a brief burst produced inside thunderstorms and associated with lightning. ... Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. ... The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected. ...
