You’d think it would be easy to tell if an object in space was a star or a planet - is it big, hot, and shining? It’s a star! Small, cool, and made of rock and gas? Planet! But cosmic oddities know as brown dwarfs remind us that the universe is more complicated and interesting than that.

The ESA Hipparcos team worked for 20 years on the project, then had to watch as the mission ALMOST failed! But somehow, they turned it around, and today, this little-known mission has totally transformed what we know about space.

The star-mapping satellite Gaia has found more than 20 stars speeding across the Milky Way toward intergalactic space. There are just a few things that can slingshot a star out of a galaxy and all of them take some extreme gravitational interactions.
