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

Proba-3 has spent its first year in orbit generating more than 50 artificial solar eclipses, giving scientists sustained access to the inner solar corona that previously could only be studied intermittently during brief total eclipses on Earth. The two-satellite ESA mission is designed to supply the missing observations between the solar disc and the well-studied outer corona, and recent data co
