Short-lived optical flare AT2022zod is an unusual tidal disruption event, astronomers find
An international team of astronomers has investigated a short-lived optical flare designated AT2022zod. As a result, they found evidence indicating that this flare is an unusual tidal disruption event. The findings were presented ...
It's the JWST's turn to look for an intermediate mass black hole
Intermediate mass black holes (IMBH), if they exist, have between about 100 and 1,000 solar masses, placing them in between stellar black holes and supermassive black holes. But while there's plenty of evidence for both stellar ...

An adolescent growth spurt in young stars helps giant planets form
Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. ...
