Laser Guide Stars are artificial stars that we generate on the sky wherever we want. Green and orange lasers are launched from the ground to help adaptive optics systems correct for the atmospheric effects on astronomical observations and space applications. Would you like to have your own star too?
This talk was part of our Public Astronomy Night on 17 July 2020. You can also watch a recording of the talk here on our Facebook page (see the 'Public Astronomy Nights' playlist).
