The amateur videographers that captured the fiery meteor streaking across the sky over Chelyabinsk, Russia earlier this month have can now be credited for more than their viral videos. The footage has been used in a scientific study that's determined where the unexpected object likely came from.
Despite what's been portrayed in Armageddon-type movies, there's little that can be done to stop asteroids, meteors and other forms of space debris from entering the Earth's atmosphere. But that's no reason to panic, says one expert.
Cuba apparently experienced a phenomenon similar to but smaller than the meteorite that detonated over Russia this week, island media reported, with startled residents describing a bright light in the sky and a loud explosion that shook windows and walls.
The meteor that streaked through the sky over Russia caught local residents and astronomers by surprise. Contrast that to the asteroid that’s expected to fly by our planet Friday; scientists have been tracking that object for months. Why are both rocks coming at Earth at the same time? And why did astronomers know about one, but not the other?
The meteor that exploded in the sky above Russia, injuring hundreds in a damaging shockwave and rain of fragments, and raising questions about the dangers that could come from space. Here's some answers to those questions and more.
