And as the article states, in the 1990’s, we could only document about 8000 stars and planets. Gaia will document nearly 2bn, and, as you mentioned, we are only going to learn about billions and billions more in the coming years. Thank you to the ESA and all of the world’s scientists for seeking this knowledge and getting us closer and closer to that holy grail of knowing how our universe was born. The future looks bright!!
