In lieu of the first Gaia Galaxy Map released a few days ago, Jonathan Woodbury explains his experiences along with how space maps are made!!
Only in the last few generations have we known the nature of the stars. Now we take it for granted and rarely think about it. Yet there may be a surprise right under our nose. Could the Sun have a companion star, shining in plain sight, that we have overlooked? Jonathan’s talk will describe how we could have overlooked a companion star for over a century and how we may find it soon.
