Our June meeting looked at Space telescopes, particularly Gaia and Euclid space telescopes.
Gaia was launched in 2013 for a 10.5 year survey of the solar system, the Milky Way, and beyond, using it's billion pixel camera intending to produce a 3D map of our galaxy.
Euclid was launched in 2023 and is a wide angle telescope and over the next six years it tracks the shapes, distances and movements of galaxies as far as 10 billion light-years away. Not only will this result in the largest 3D map of the cosmos ever created, but the vast scale of this map will help scientists investigate the mysteries of dark matter and dark energy, sometimes collectively known as the "dark universe."
