Studies of young brown dwarf Rho Ophiuchi 102 with radio showed the presence of a dust disk around a millimeter particles normally encountered in protoplanetary disks of young stars. Using radio telescopes Atacama Large Millimeter / submillimeter Array, astronomers unexpectedly found that the outer region of the dust disk surrounding a brown dwarf, contains solid grains of millimeter size. Similar findings previously found only in dense protoplanetary disks around newborn stars, and therefore the discovery challenges the theory of the formation of rocky terrestrial planets, and suggests that such Read more [...]
Says Jane Houston Jones of NASA's Jet Propulsion Laboratory in Pasadena, Calif.: What happens in December? Star Fireworks finish the year with a bang. Gemini (Gemini) - one of the ones that are dazzlingly bright winter. Gemini will rise in the northeast near another beautiful constellation - Orion. Geminids - usually one of the best meteor showers of the year. Although the peak activity of the shower will be short, on the night of 13 to 14 and 14 to 15 of November forecast to 120 meteors per hour if the sky above your region at this time is dark.
