Image: Herschel's view of the galactic centre

An odd-shaped formation of gas and dust at the centre of the Milky Way, captured by the far-infrared cameras on board ESA's Herschel space observatory. The nearly continuous strip of dense and cold clumps of material forms ...

Image: Reflection nebula NGC 1999

This spooky sight, imaged by the NASA/ESA Hubble Space Telescope, resembles fog lit by a streetlamp swirling around a curiously shaped hole – and there is some truth in that. While the 'fog' is dust and gas lit up by the ...

Magnetic fields in massive star formation cores

Studies of molecular clouds have revealed that star formation usually occurs in a two-step process. First, supersonic flows compress the clouds into dense filaments light-years long, after which gravity collapses the densest ...

First look at gravitational dance that drives stellar formation

Swirling motions in clouds of cold, dense gas have given, for the first time, an active insight into how gravity creates the compact cores from which stars form in the interstellar medium. The results will be presented today, ...

The lifetimes of massive star-forming regions

Astronomers can roughly estimate how long it takes for a new star to form: it is the time it takes for material in a gas cloud to collapse in free-fall, and is set by the mass, the size of the cloud, and gravity. Although ...

Collaboration uncovers the origin of extraordinary supernovae

Astronomers using the OISTER telescope consortium in Japan have uncovered new information about the origin of 'extraordinary supernovae' explosions, which are brighter than normal ones. This new information will help improve ...
