This week is the BBC’s Stargazing Live show: three now-annual nights of live stargazing and astronomy chatter, live from Jodrell Bank. CBeebies are also getting in on the act this year, which I’m excited about. The Zooniverse are part of the show for the third year running and this time I have the pleasure of being here on set for the show. In 2012 the Zooniverse asked the Stargazing Live viewers to help us discover a planet with Planet Hunters, in 2013 we explored the surface of Mars with Planet Four. This year we are inviting everybody to use our Space Warps project to discover some of most beautiful and rare objects in the universe: gravitational lenses.
Space Warps asks everyone to help search through astronomical data that hasn’t been looked at by eye before, and try to find gravitational lenses deep in the universe. We launched the site in 2014 and for Stargazing Live we’re adding a whole new dataset of infrared images. Your odds of finding something amazing are pretty good, actually!
Gravitational lenses occur when a massive galaxy – or cluster of galaxies – pass in front of more distant objects. The enormous mass of the (relatively) closer object literally bends light around it and distorts the image of the distant source. Imagine holding up a magnifying glass and waving it around the night sky so that starlight is bent and warped by the lens. You can see more about this here on the ESO website.
We’ve been getting things ready all day and now I’m sitting here in the Green Room at Jodrell Bank waiting for the show to begin. Stargazing Live is an exciting place to be and everyone is buzzing about the show! That Chris Lintott bloke from the telly is here, as is K9 is from Doctor Who – they both look excited.
