Scientists Figure Out Where That Russian Meteor Came From
On February 15, a meteor shook Russia as it entered the Earth’s atmosphere above the Urals. Now, scientists believe they know where in the universe it came from.
Future Asteroids Could Be Deflected With Nothing But Space-Graffiti
Our planet’s recent close call with one asteroid direct visit from another has definitely made it seem important to consider how to avoid the pesky things in the future. One solution is to direct the Sun’s power into pulverising lasers, but another option just involves covering incoming rocks with spray paint.
Monster Machines: Tiny Telescopes Could Save Earth From A Deep Impact
A 15m wide, 10,000-tonne meteor that packs triple the force of the nuke dropped on Hiroshima is nothing to scoff at. But in the grand scheme of things, the meteor that hit Chelyabinsk, Russia, last week is a cosmological runt. Space rocks as much as 30m across are estimated to strike every 100 years or so and those like the 50m diameter Tunguska meteor of 1908 hit maybe once a century.
Near-Earth Asteroids Don’t Look So Scary In This Australian Time-Lapse
Most of us got a little distracted from uneventful passing of near-Earth asteroid DA14 after that unrelated meteorite decided to slam into Russia. Photographer Colin Legg keep his eyes — and camera — on DA14 though, and put together that makes it seem like an insignificant little dot.
Watch Last Week’s Asteroid Fly By Peacefully Instead Of Destroying Us
That little white pixelated bean spinning around above might look more like a bad ’80s video game than the near-messenger of quick and devastating apocalypse, but that’s what happens when you’re taking shots 120,000km away from your subject. What you’re seeing is in fact 2012 DA14 at a resolution of around 4m per pixel over an eight-hour period just as it was mercifully passing our beautiful space marble by on the evening of February 15.
Maybe The Sun Could Vaporize Asteroids To Avoid This Whole Collision Issue
Two large flying space rocks have hit or almost hit Earth lately. I think everyone agrees that this needs to not be happening. So two California researchers are developing a plan for destroying asteroids in space. Get after it.
Aussie Observatories Had Front-Row Seats To Asteroid 2012 DA14. Here Are The Videos
27,700km sounds far, far away… but not when you’re talking about a 50m wide, 190,000t asteroid. In this case, it’s 2012 DA14, which made its pass by our tiny area in the Solar System in the early hours of Saturday. It was close enough for a number of telescopes to get a clear view of its journey, including three based in Australia.
