Lagrange Point

Boiling planets being stretched and squished. Tiny white dwarf stars going supernova. Goldilocks planets potentially with liquid water. Exoplanet hunting is now a lot easier with missions like TESS and veterans like Hubble. We look at some special cases, and how searching for 1 planet can uncover loads more. Sometimes planets are lurking in old observatory data, we just need to know where to look. Too hot, too cold, GJ357 potentially has a planet that's just right with liquid water. What causes a White Dwarf to go supernova? It needs more than itself to kickstart it into a Type 1a nova...so where does the extra boost come from? Devouring another planet? Or another star?
