As wireless systems evolve from 5G to 6G, engineers are working toward networks that connect satellites in orbit, airborne platforms such as drones, and dense constellations of ground devices into a single space air ground integrated network or SAGIN. This convergence creates a complex electromagnetic environment where large numbers of signals overlap and interfere, making spectrum control and p

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

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

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
