The sun, like all stars, was born in a giant cold cloud of molecular gas and dust. It may have had dozens or even hundreds of stellar siblings – a star cluster – but these early companions are now scattered throughout ...
Star formation is one of the most important research fields in astrophysics. This process, in which gravitational instabilities cause the collapse of gas to form more compact structures and finally stars, encompasses a broad ...
This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the area surrounding Sagittarius A*, the supermassive black hole that lurks at the centre of the Milky Way—highlighted here with a small circle. ...
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 ...
Disc galaxies like our own Milky Way, characterized by a flattened disc of stars and gas (often with a central bulge of material as well) have a wide range of masses, spatial extents, and stellar content. Nonetheless all ...
A Yale-led research group has created the most detailed maps yet of a vast seedbed of stars similar to Earth's Sun.
An international team led by researchers at CNRS, Université Grenoble Alpes and the French Alternative Energies and Atomic Energy Commission (CEA) has challenged currently held ideas about star formation. Published in Nature ...
Researchers have found new methods to measure the internal pressure and surface tension of nano-sized drops of liquid like those involved in cloud formation and airborne pollutants to study how they behave in different environments. ...
Two research teams used a map from NASA's Stratospheric Observatory for Infrared Astronomy, SOFIA, to uncover new findings about stars forming in Orion's iconic Horsehead Nebula. The map reveals vital details for getting ...
