An eleventh hour reminder if you are one of the seemingly only three people in the UK not watching BBC Stargazing LIVE that tonight (Wednesday) is the final day of this three day event and you can watch or take part live.

The main event is happening on BBC2, 8 – 9:30pm with Brian Cox and Dara O’Briain presenting the third programme which will feature aliens and the hunt for new worlds, as well as astronomer Mark Thompson in the small town of Dulverton, asking all the residents to turn off their lights before going outside to observe the skies (relatively) free of light pollution.

As well as this, they will be featuring some of the hundreds of live events going on all around the country at amateur clubs and professional observatories, many of which you could still take part in. The full listings are on the Stargazing LIVE website, but the best bets for Londoners seem to be:

The Hub at Regents Park: Run by the British Astronomical Association, use their telescopes and binoculars to view Jupiter and other objects in the sky with experts on hand to talk about what you’re seeing. 6:30 – 10pm; free; all welcome.

The Hampstead Observatory: Run by Hampstead Scientific Society, another chance to see Jupiter and its moons, with informal talks as well as observing. 8-10pm, also running Thursday/Friday/Saturday/Sunday, at varying times. Free; all welcome.

The activities don’t stop with the TV programme; free public events continue for the next few days with Loughton Astronomical Society hosting several talks and public observing sessions on Thursday, Saturday and next Thursday, Ruislip Lido playing host to the West of London Astronomical Society for Public Observing of Friday, Saturday and Sunday and a host of events further out including New Malden, Luton and Guildford.
