Light Gives Asteroids Spin
87131
Astronomers have observed an asteroid change the rate at which it spins for the first time, and shown that this is due to a theoretical effect predicted but never before seen.

New observations of dust around young stars suggests collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn't likely stop the formation of rocky planets like Earth, a process that may well be common, the results suggest.

Austrian researchers have teleported photons, or particles of light, for the first time outside a laboratory using the same technological principles imagined by Star Trek.

Scientists tracking an asteroid approaching Mars say that an impact with the Red Planet has become less likely. Refined estimates of the asteroid's orbit were made using new observations from a telescope at the Calar Alto Observatory in Spain, according to the Near-Earth Object Program at NASA's Jet Propulsion Laboratory.

It's the year 2020, and space has never been so busy. Picture this:In Earth orbit, a robotic maintenance ship skitters from one weather satellite to another, upgrading powerful optics that help meteorologists track dangerous storms.

This summer, NASA will launch a robotic probe to visit two stange and giant asteroids--one is covered with ice while the other may have been blasted by an ancient supernova.  The tales these asteroids tell may reveal the true beginnings of our solar system.

While a terrestrial view of a galaxy might disguise the turbulent, changing mergers that fuel their formation, a famous cluster called Stephan's Quintet shows that seemingly immutable stars are always in flux.    Astrobiology Magazine -- A stunning image released by the Gemini Observatory captures the graceful interactions of a galactic ballet, on a stage some 300 million light years away, that might better be described as a contortionist's dance...

A comet discovered earlier this year has now moved close enough to be visible without binoculars or telescopes by experienced observers under dark skies. It is expected to put on a modest show this month and into January.

Planet-building is dusty work, and now two space telescopes have captured images of cosmic construction materials: disks of dust circling stars about the same size as our sun.
