Gaia’s galaxy. Don’t know what Gaia is? In Greek mythology Gaia is a goddess and the mother of all earthly life.  Gaia is also Earth, the planet we live on. There’s way more to it, but not for this article.

The Gaia I’m talking about is an exploration spacecraft developed by ESA (the European Space Agency) and launched atop a Soyuz rocket in 2013. It’s the successor to ESA’s Hipparcos (1989-1993). I know, that’s nearly 10 years ago, so why talk about it now? Because Gaia’s mission is HUGE. The information it produces will be on the same level of importance as the James Webb Space Telescope.
