A star has been destroyed by a wandering supermassive black hole
Skip to content Second supermassive black hole is a long way from the galaxy’s core. Back in 2024, a system […]
New study: There are lots of icy super-Earths
“Microlensing” lets us find planets at much greater distances from their star. What does the “typical” exosolar system look like? […]
Skepticism greets claims of a possible biosignature on a distant world
It’s really difficult to get a clear sign of life on an exoplanet. On Wednesday, news broke that researchers had […]
