Comet ISON is coming!

Comet ISON is coming!

As Comet ISON draws near to its close approach with the Sun in November, much uncertainty remains over how brilliant it will be. Dominic Ford speaks to Matthew Bishop at the Lowell Observatory to find out more. He also talks to Apostolos Christou from the Armagh Observatory about a group of asteroids which closely follow the orbit and Mars, and appear to fragments of a much larger pair of asteroids which collided. Tamela Maciel from the Cavendish Laboratory in Cambridge reports on the lonely exoplanet which doesn’t seem to have a parent star, and Kirsten Gottschalk from the International Centre for Radio Astronomy Research reports that the non-detection of gravitational waves by radio astronomers is starting to rule out some theories of how black holes grow.

Sue in a Centrifuge

Space Boffins Sue Nelson and Richard Hollingham discover what it’s like to undergo G forces with a special podcast from QinetiQ’s centrifuge facility – the only one of its kind in the UK. As Sue spins around, guests Dr Jon Scott and Dr Simon Brown discuss the physical stresses on the body and the demands on astronauts and pilots. There’s also a close up look at the James Webb Space Telescope mirrors and we hear from veteran US pilot Wally Funk, who had the right stuff to become an astronaut in 1960 but is still waiting for her chance to go into space.
