The first "sniffs of air" of two huge far-away planets reveal that they seem to be missing water, a surprising finding amid weather unlike any planets in our solar system with blast furnace-like gusts amid supersonic winds.

New observations of dust around young stars suggest collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn&#39;t likely stop the formation

A group of European-led astronomers has made a photograph of what appears to be a planet orbiting another star. If so, it would be the first confirmed picture of a world beyond our solar system.

Hot, steamy star Somewhere in the universe, a solar system is forming. Whirling around the newly ignited stellar embryo is a disk of dust, gas, and rocks that will gradually settle down into a stable planetary system. And according to astronomers using the Spitzer space telescope, the natal cloud - the region where planets will form - is being deluged with water vapour.â¦

European Space Agency -- ESAÃ¢ÂÂs quartet of space-weather watchers, Cluster, has discovered vortices of ejected solar material high above the Earth.     The superheated gases trapped in these structures are probably tunnelling their way into the EarthÃ¢ÂÂs magnetic Ã¢ÂÂbubbleÃ¢ÂÂ, the magnetosphere...

Astronomers using NASA's Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.

Planets are built over a long period of massive collisions between rocky bodies as big as mountain ranges, astronomers announced today. New observations from NASA's Spitzer Space Telescope reveal surprisingly large dust clouds around several stars.
