NASA research reveals Saturn is losing its rings at ‘worst-case-scenario’ rate
New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago.
Did supernovae kill off large ocean animals at dawn of Pleistocene?
About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova
Mars moon got its grooves from rolling stones, study suggests
A new study bolsters the idea that strange grooves crisscrossing the surface of the Martian moon Phobos were made by rolling boulders blasted free from
Ancient Egyptians discovered Algol’s variability 3,000 years before western astronomers
Astronomers and Egyptologists demonstrate how ancient Egyptian calendars were used to describe the behaviour of astronomical observations, in particular, the star system Algol.
