Incoming: The Earth-Moon system has company tonight.
The Asteroid: Near Earth Asteroid 2010 WC9 is back. Discovered by the Catalina Sky Survey outside Tucson, Arizona on November 30th, 2010, 2010 WC9 was lost after a brief 10 day observation window, and was not recovered until earlier this month. About 71 meters in size, 2010 WC9 is one of the largest asteroids to pass us closer than the Earth-Moon distance.
Children ice skating in Khakassia, Russia react to the fall of a bright fireball two nights ago on Dec.6 In 1908 it was Tunguska event, a meteorite exploded in mid-air, flattening 770 square miles of forest. 39 years later in 1947, 70 tons of iron meteorites pummeled the Sikhote-Alin Mountains, leaving more than 30 craters. […]
36 years ago today, a strange event was detected over the Southern Indian Ocean that remains controversial. On September 22nd, 1979, an American Vela Hotel satellite detected an atmospheric explosion over the southern Indian Ocean near the Prince Edward Islands. The event occurred at 00:53 Universal Time on the pre-dawn nighttime side of the Earth. […]
All right, sure – there are a lot of asteroids that don’t hit us. And of course quite a few that do… Earth is impacted by around 100 tons of space debris every day (although that oft-stated estimate is still being researched.) But on March 10, 2015, a 12–28 meter asteroid dubbed 2015 ET cosmically “just missed us,” […]
How hazardous are the thousands and millions of asteroids that surround the third rock from the Sun – Earth? Since an asteroid impact represents a real risk to life and property, this is a question that has been begging for answers for decades. But now, scientists at NASA’s Jet Propulsion Laboratory have received data from […]
“The fact that none of these asteroid impacts shown in the video was detected in advance is proof that the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck.” – Ed Lu, B612 Foundation CEO and former NASA astronaut When we think of recent large asteroid impacts on Earth, only a […]
Why does Russia seem to get so many bright meteors? Well at 6.6 million square miles it’s by far the largest country in the world plus, with dashboard-mounted cameras being so commonplace (partly to help combat insurance fraud) statistically it just makes sense that Russians would end up seeing more meteors, and then be able to share […]
Got some ideas about how to snag an asteroid? NASA has just announced $6 million in opportunities for its asteroid retrieval initiative, which would see astronauts explore one of these space rocks in the 2020s if the agency receives budgetary approval to go through with the idea. First proposed in the 2014 fiscal year budget […]
Fancy yourself an asteroid hunter? There’s $35,000 available in prizes for NASA’s new Asteroid Data Hunter contest series, which will be awarded to citizen scientists who develop algorithms that could be used to search for asteroids. Here’s where you can apply for the contest, which opens March 17 and runs through August. And we have a […]
Looking at the power of the Chelyabinsk meteor (which struck a year ago and is visible starting around 1:15 in the video above) is still terrifying all these months later. Happily for those of on Earth worried about these big space rocks, the world’s space agencies are taking the threat seriously and are starting to […]
