New virtual laboratory for merging neutron stars

For the first time, a high-performance computer will make it possible to simulate gravitational waves, magnetic fields and neutrino physics of neutron stars simultaneously.

Black hole pair born inside a dying star?

Far from earth, two black holes orbit around each other, propagating waves that bend time and space. The existence of such waves—gravitational waves—was first predicted by Albert Einstein over a century ago on the basis ...

Penrose's and Hawking's early math award revisited

In 1966, it was Roger Penrose who won the prestigious Adams Prize for his essay "An analysis of the structure of space-time." The Adams Prize – named after the British mathematician John Couch Adams – is awarded each ...

Seeking the earliest galaxies with cosmic telescopes

(Phys.org)—With a recent NSF award, UA scientists will use galaxy clusters as astronomical lenses to peer farther into the depths of space than any manmade telescope is capable of viewing - to the time when the universe's ...

Large water reservoirs at the dawn of stellar birth

(Phys.org)—ESA's Herschel space observatory has discovered enough water vapour to fill Earth's oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star.

Cyanoacetylene in IC 342

Star formation is an incredible process, but also notoriously difficult to trace. The reason is that the main constituent of stars, hydrogen, looks about the same well before a gravitational collapse begins, as it does in ...
