A new class of dim supernovae

The colossal stellar explosions called supernovae come in many kinds and flavours. Some of them are produced when a massive star reaches the end of its life in a sudden gravitational collapse. Astronomers have just found ...

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 ...

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 ...

A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly ...

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.
