FREE REFRESHER ON THE AMAZING GAIA SATELLITE
Wednesday, Feb. 7, 2024
7–8:30 PM online
IN PREPARATION FOR THE AAA LECTURE, TUESDAY, FEB. 13
Gaia is a satellite of the European Space Agency (ESA). Since 2013 it has become the gold standard for astronomy measurements and revealed amazing insights into our galaxy. It has taken data on about 2 billion stars in our sector of the Milky Way Galaxy, for most of the 32,000 lightyears to the galaxy’s center.
On Tuesday, February 13, Dr. Rocio Kiman, of Cal Tech, will present the free monthly AAA lecture on breakthroughs from Gaia’s recent data releases and on her own research on dwarf stars using Gaia data.
This February 7 pre-lecture class may help attendees better understand that subsequent talk by reviewing the history and workings of the Gaia satellite. We’ll review key features like its instruments, parallax, photometry, spectra. We’ll also view images and videos derived from previous Gaia data. This review will be presented by David Kiefer, Chair of AAA Classes Committee.
