from Io9, quite a brilliant article to think about…
ok, geek alert but I had a really fun time playing around with this…
Want to know what would happen if a 10km-wide asteroid came out of the sky and slammed down on your city?
Scientists at Purdue University and Imperial College London have updated their popular impact effects calculator first produced in 2004.
Users dial in details about the hypothetical impactor, like its diameter and density.
The web program then estimates the scale of the ensuing disaster, such as the size of the crater left behind. It will also tell you how far away you need to be to avoid being buried by all the material thrown out by the blast, or set on fire.
This is just soooooo cool… I noticed that I can’t get the video to show the year and number of the asteroids so click on the ‘Watch youtube’ to get the full picture if you are interested.
Video Created by Scott Manley, this is a view of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones.
The final colour of an asteroids indicates how closely it comes to the inner solar system.
Earth Crossers are Red
Earth Approachers (Perihelion less than 1.3AU) are Yellow
All Others are Green
Ok, I know this is geeky but I do love astronomy and the new science but do read this article, quite fascinating. You think that planets are nice round things and then you find out that they are eating as well, damn.
Jupiter became the solar system’s biggest planet by consuming its chief rival, a massive rocky planet ten times bigger than Earth. New discoveries suggest Jupiter and Saturn learned a lesson from their mythological namesakes, "eating" any planet that opposed them. Read more at Io9…
