Unusual supernova opens a rare window on the collapse of a star

An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation's (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF's Kitt Peak National ...

Computer simulation sheds new light on colliding stars

Unprecedented detail of the aftermath of a collision between two neutron stars depicted in a 3-D computer model created by a University of Alberta astrophysicist provides a better understanding of how some of the universe's ...

Image: Multi-wavelength view of a supernova remnant

New Year's Eve may be past, but we are not done with fireworks just yet. This image, which includes data from ESA's Herschel Space Observatory, shows the remnants of an explosion – not of the colourful type ignited during ...

Second scientific balloon launches from Antarctica

Washington University in St. Louis announced that its X-Calibur instrument, a telescope that measures the polarization of X-rays arriving from distant neutron stars, black holes and other exotic celestial bodies, launched ...

ESA sets clock by distant spinning stars

ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The "PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars.

Scientists detect biggest known black-hole collision

An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun – and ...
