A surprise meteor shower spotted in February was likely caused by cosmic “bread crumbs” dropped by an undiscovered comet that could potentially pose a threat to Earth.The tiny meteoroids that streaked through Earth’s atmosphere for a few hours on Feb. 4 represent a
NASA’s Wide-field Infrared Survey Explorer (WISE) has found the very first asteroid that (more or less) shares an orbit with Earth! Called 2010 TK7, this asteroid is about 300 meters (roughly 1000 feet) across, and is the first in an up-to-now theoretical class of
The six-member crew of the International Space Station took shelter in two Russian Soyuz spacecraft early Tuesday because of a predicted close approach by an unknown piece of space debris.Safety procedures are put into effect when radar tracking indicates debris

Bits and pieces of the famous Halley’s Comet will light up the overnight sky in a promising meteor shower, weather permitting, skywatching experts say.The annual Eta Aquarid meteor shower will peak early tomorrow morning (May 6) and is expected to put on a
In a controversial study, gravity maps of the Antarctic continent have revealed what could be multiple asteroid impact sites. Gravity anomalies in Antarctica might mark spots where hundreds of thousands of years ago the frozen continent was struck by giant…
Every year in late April Earth passes through the dusty tail of Comet Thatcher (C/1861 G1), and the encounter causes a meteor shower–the Lyrids. This year the shower peaks on Friday morning, April 22nd. The best time to look, no matter where you live, is
