A deep field view with Hubble's WFC3 camera has resolved and analysed the population of uyoung blue stars in the halo of the Andromeda galaxy.

Star formations comes in many different sizes and shapes: Small and large stars are formed from in a variety of different environments. But why and how? A new research concludes that even-thoigh the results looks very different, the basic rules are allways the same!

Using NASA's Hubble Space Telescope, astronomers have solved a longstanding mystery on the type of star, or so-called progenitor, that caused a supernova in a nearby galaxy in 1987. The finding yields new observational data for pinpointing one of several scenarios that could trigger such outbursts.

Using observations from NASA's Rossi X-ray Timing Explorer (RXTE) satellite and the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) radio telescope, an international team of astronomers has identified the moment when a black hole in our galaxy launched super-fast knots of gas into space.
