What's On
If you are not a member of Wycombe Astronomical Society,
you are welcome to attend any of our meetings on a trial basis and with no charge.
Our hope is, therefore, to encouraging new members to join our Society.

The European Space Agency’s Gaia satellite is mapping our Milky Way Galaxy from space. The satellite is measuring fundamental properties of stars: their distance (parallax), how they move (proper motions and radial velocities) and their atmospheric parameters. The mission is revolutionising astrophysics because its data are being used in nearly every field of astronomy - it has overtaken Hubble as the most scientifically productive satellite. I will summarise the content of Gaia’s Data Release 3, which will be released in June 2022. Amateur astronomers are encouraged to follow-up Gaia alerts on transient objects and asteroids.
ABOUT GEORGE
George obtained his Astrophysics PhD, "Probing the Milky Way galaxy through thick and thin (discs and halo) with the Correlation Radial Velocities (CORAVEL) and Radial Velocity Experiment (RAVE) surveys" from Cambridge in 2007, supervised by Gerry Gilmore and Wyn Evans. Ever since then he has been a post-doc funded by the UK Gaia…
