11 Dec 2012 A New Meteor Shower in December?
If you're outdoors after sunset this week, be alert for meteors. Not only is the Geminid meteor shower active as Earth passes through a stream of debris from "rock comet" 3200 Phaethon, but also, say forecasters, a new meteor shower could make an appearance.  "The source of the new shower is Comet Wirtanen," says Bill Cooke of NASA's Meteoroid Environment Office. "Dust from this comet hitting Earth's atmosphere could produce as many as 30 meteors per hour."
16 Nov 2012 How to Watch the Leonid Meteor Shower This Weekend
From Friday, November 16 to Sunday, November 18 the Leonid meteor shower will be at its peak, with 20 to 30 or so shooting stars visible per hour.  If you've ever wanted to sit outside and soak up a meteor shower, this is your big chance: the Moon is new, so it won't interfere at all with the shower.
2 Nov 2012 Scientists Monitor Comet Breakup
The Hergenrother comet is currently traversing the inner-solar system. Amateur and professional astronomers alike have been following the icy-dirt ball over the past several weeks as it has been generating a series of impressive outbursts of cometary-dust material. Now comes word that the comet's nucleus is splitting apart.
12 Oct 2012 The Orionid Meteor Shower
Every year in mid-to-late October, Earth passes through a stream of dusty debris from Comet Halley, and the pre-dawn sky lights up with a pretty display of shooting stars. "We expect to see about 25 meteors per hour when the shower peaks on Sunday morning, Oct 21st," says Bill Cooke, the head of NASA's Meteoroid Environment Office. "With no Moon to spoil the show, observing conditions should be ideal."
25 Sep 2012 Big Sun-Diving Comet Discovered
Currently located beyond the orbit of Jupiter, Comet C/2012 S1 (ISON) is heading for a very close encounter with the sun next year. In Nov. 2013, it will pass less than 0.012 AU (1.8 million km) from the solar surface. The fierce heating it experiences then could turn the comet into a bright naked-eye object.
