Wide Angle: Balls Of Fire!

Meteors and meteorites are both meteroids when in space, but they are entirely different entities when screaming through our atmosphere. Sit back and enjoy the lightshow as we uncover the nature of these balls of fire...
 

Not Just Comet Dust

'Meteors' burn up very quickly as they blast through our atmosphere. 'Meteorites' are bigger and survive the burn and hit the ground. Both are known as 'meteoroids' when in space. However, should a meteoroid's diameter exceed 10 meters, the chunk of space rock becomes an 'asteroid' (and a whole lot more terrifying when heading our way). Credit: NASA

  • Slide Show: Top 5 Meteorite Uses
    If you found a meteorite, what would you do with it? Would you keep it as an ornament? Sell it on eBay? Carve it into a crude space weapon? Before you try any of the above, read our top 5 uses for meteorite fragments that have already been tried and tested...

  • News: Meteorite Proves Mars Had Thicker Atmosphere
    Mars Exploration Rover Opportunity has discovered a huge iron-nickel meteorite on the surface of Mars. However, this isn't a routine find. For the meteorite to have been discovered at all, Mars needed to have a far thicker atmosphere in the past to slow the thing down before hitting the martian surface...

  • News: Shooting Star Hunt Yields Meteorite
    In March 2009, an amazing event stunned the world. A small asteroid was tracked by scientists before it hit our atmosphere. When the rock did hit the skies over Sudan, it exploded to life, scattering meteorite fragments over the African desert...

  • News: Killer Asteroids May Escape NASA's Notice
    Meteorites come in all sizes, but once they become more asteroid-like than meteoroid-like, we're in for a rough ride should one be heading toward Earth. Unfortunately, NASA may not even have sufficient funds to spot the next devastating asteroid...

  • Video: Fireballs from Space: Reenacting a Meteor's Impact
    How can you understand the dynamics of a meteorite impact? You build a 25 foot-long gun capable of blasting an aluminum bullet 4 miles per second of course!

  • Video: Fireballs from Space: The Yukon Meteor
    Fireballs can be startling events. As a sizable meteoroid enters the Earth's atmosphere, it burns like a meteor and then explodes, often scattering bits over a wide area. The Yukon meteor was one such event...

    Dave Mosher chats with former astronaut Rusty Schweickart about the dangers of near-Earth asteroids and humanity's danger to itself in stopping them.

  • Blog: Ignoring a Clear and Present Danger (Cosmic Ray)
    Why does the risk of a devastating asteroid impact seem to send members of Congress asleep when NASA asks for more money to search for these harbingers of doom? Ray Villard investigates...

This Week's Other Wide Angles

Visit our other Wide Angles running on Discovery Earth and Discovery Tech:


Discovery Earth: Good Bug, Bad Bug (a.k.a. 1st Annual Bug Week)
Humanity has a mixed relationship with bugs, insects and creepy-crawlies in general. In this wide angle we look at some of the ways we're battling bugs and other small, none-to-welcome critters with whom we share the planet.


Discovery Tech: Tissue Engineering
We can rebuild him. We have the technology. Ok, it's not the bionic man, but tissue engineering is changing the face of medicine. It applies the principles of engineering and life sciences to grow bones, cartilage, blood vessels, bladders and even print organs. What does tissue engineering entail and what does it promise for the future of medicine? This Wide Angle series on Tissue Engineering will explore those questions and more.
