South Pole telescope detector aids study of the universe
Center for Nanoscale Materials (CNM) users from Argonne's High Energy Physics and Materials Science divisions helped design and operate part of the South Pole Telescope, a project that aims a large telescope ...
Young stars paint spectacular stellar landscape
Astronomers at ESO have captured the best image so far of the clouds around the star cluster NGC 3572. This image shows how these clouds of gas and dust have been sculpted into bubbles, arcs and the odd features ...
Cosmic rays zap a planet's chances for life
Mysterious cosmic rays constantly bombard Earth from outer space. Now scientists find these energetic particles could limit where life as we know it might exist on alien planets.

Old young stars
(Phys.org) —The early stages of a star's life are critical both for the star and for any future planets that might develop around it. The process of star formation, once thought to involve just the simple ...
Image: NGC 6946, "the fireworks galaxy"
NGC 6946 is a medium-sized, face-on spiral galaxy about 22 million light years away from Earth. In the past century, eight supernovas have been observed to explode in the arms of this galaxy.
Hubble catches stellar explosions in NGC 6984
Supernovae are intensely bright objects. They are formed when a star reaches the end of its life with a dramatic explosion, expelling most of its material out into space.
Stars born in filaments tend to outweigh stars formed in the field
The mass distribution of stars is called the initial mass function, or IMF for short, and it characterizes the properties not only of our Milky Way, but of all the other galaxies we observe as well. But is ...

The details of how massive stars explode remains one of the biggest questions in astrophysics.
New type of black-hole quasar discovered
(Phys.org) —Like our Milky Way, every known large galaxy has at its center a supermassive black hole, some of which are surrounded by a super-bright disk of hot gas called a quasar—but now a research ...
