Analysing Asteroids

Asteroid 4 Vesta from Dawn on July 17, 2011. The image was taken from a distance of 9,500 miles (15,000 km) away from Vesta. (c) NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

We're analysing asteroids in this edition of the Naked Scientists, as Earth is due a very near miss next week!  We'll also meet the asteroid miners Ė companies looking to go prospecting in outer space - to find out how to mine an asteroid.  Plus, the new material that can generate electricity from the heat in your hand, and what will the Large Hadron Collider be looking for next...

  • 01:35 - Electricity at your (hot) fingertips

    A group of Korean researchers have produced flexible films of thermoelectric material that can generate electricity with nothing more than the heat produced by a fingertip.

  • 04:59 - What's Next for the LHC?

    Still glowing from one of the scientific discoveries of the decade - the Higgs boson - the Large Hadron Collider at CERN, Europe's particle physics facility in Switzerland, is about to shut down for two years while it undergoes a refit...

  • 16:30 - The Demise of the Dinosaurs

    A team led by Paul Renne at the Berkeley Geochronology Center in California have shed new light on the asteroid impact that is believed to have wiped out the dinosaurs, 66 million years ago.

  • 20:21 - LiFi: Using light to send information

    A spinoff of that Wi-Fi is a Li-Fi. This is a system that uses visible light to send information into mobile devices and computers...

  • 38:14 - Mining Asteroids for Mineral Wealth

    A number of enterprising individuals are developing ways to harvest and mine asteroids for the minerals that they may contain...

  • 47:41 - How to make a Solar System

    How did the solar system, from massive gas planets like Jupiter down to tiny asteroids, form? New computer modelling may have the answers...

  • 53:49 - Can you create a miniature Mars at home?

    I want to be a space scientist when I grow up, but first, I want to do an experiment at home. I want to find out if we can grow plants on Mars. So, to test this, how can we make a small Mars at home?
