Astronomers discover cosmic dust storms from Type Ia supernova
Feb 09, 2024 (Nanowerk News) Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers from China, the United States, Chile,...
Migration solves exoplanet puzzle
Feb 09, 2024 (Nanowerk News) Ordinarily, planets in evolved planetary systems, such as the Solar System, follow stable orbits around their central star. However, many indications suggest that some planets might depart from their birthplaces during their early evolution by migrating inward or outward. This planetary migration might also explain...
