When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of explosion - the kilonova - occurs when a pair of dense dead stars, called neutron stars, smash together, forging even heavier elements such as gold and uranium. Such heavy elements are among the basic bui

The first exoplanet discovered in 1995 was a hot Jupiter, a Jupiter mass planet orbiting its star every few days. Today, models indicate that hot Jupiters form far from their stars, similar to Jupiter in the Solar System, and later move inward. Two main migration channels are considered: high-eccentricity migration, in which gravitational perturbations excite the orbit before tidal forces circul
