Late tonight, millions living around New York City may witness the best stellar disappearing act ever seen in North America. Lucky sky-watchers with clear skies across parts of the Northeast will observe a bright star momentarily wink out early Thursday morning. Beginning at 2:07 a.m. EDT, the 45-mile-wide (72-kilometer-wide) asteroid named 163 Erigone will slip...

A newly discovered asteroid will hurtle through the Earth-moon system on Wednesday night. Everyone around the world can watch the event unfold through large telescopes that will broadcast live online. Asteroid 2014 DX110, discovered only on February 28, 2014, thankfully poses no danger since it will be missing our planet by 218,000 miles (350,837 kilometers)....

Winning an Olympic medal this weekend will make for a truly out-of-this-world experience. That’s because ten lucky athletes who earn gold at the Sochi Olympics on February 15 will also receive a bonus medal decorated with a piece of the giant meteor that smacked into the Olympics host country, Russia, exactly one year ago. UPDATE...

A glimpse of a large asteroid comes to delight sky-watchers this month, silently sailing its way through a cosmic bull’s horns and past a famous supernova remnant. In the next few weeks, the asteroid Herculina, the 532nd asteroid to be discovered, will glow in the sky at a magnitude of brightness of about 10. That should...

From exploding stars, barnstorming asteroids, and a buzzing beehive, the starry skies this week are filled with cosmic wonders to behold. Supernova Update: A surprise star exploded in a spiral galaxy 12 million light years from Earth and appears to be slowly brightening in the evening skies. The Cigar Galaxy or Messier 82 is host...

A trip to the moon on gossamer wings? While most of us Earthlings will never get to visit other worlds, here’s your chance to fly your name, at least, on a spacecraft heading to a distant asteroid in 2016. A microchip with the names etched on it will be secured to the side of NASA’s OSIRIS-REx (Origins Spectral...

A newly-discovered asteroid masquerades as a bizarre comet, one that astronomers in a new study are outright calling, “weird and freakish.” First spotted by the Hawaii-based Pan-STARRS sky survey telescope this Spring, the bizarre object caught  astronomers’ attention because of its unusually fuzzy appearance. The Hubble Space Telescope’s high-resolution cameras were trained on it in...

This week, skywatchers will be spoiled with jam-packed skies: meteors raining down, a moon-planet-star triangle and a large asteroid flyby. Meteor Shower Peaks. The year’s best-known celestial event officially peaks at 6 p.m. GMT Monday, August 12, when the Perseid meteor shower will produce anywhere from 20 to 80 shooting stars per hour, depending on...

  The 10,000 ton asteroid that exploded above the Russian city of Chelyabinsk in February produced such a powerful shockwave that it raced around the world twice, according to a new study published in the journal Geophysical Research Letters. Researchers report that 20 world-wide monitoring stations, designed to detect ultra-low frequency sound waves emanating from nuclear-test...
