Zooming in on the origins of fast radio bursts

Astronomers have peered into the home galaxies of fast radio bursts, ruling out supermassive black holes as a cause and bringing us a step closer to understanding the origins of these mysterious signals from outer space.

DY Centauri: Stellar evolution while you watch

In 1930, Dorrit Hoffleit reported that star number #4749 in the Harvard List of variables had faded four times between 1897 and 1929, and identified it as an R Coronae Borealis (RCB) variable. RCB stars are luminous low-mass ...

Image: Hubble views a galaxy burning bright

In the depths of the night sky lies a barred spiral galaxy called NGC 3583, imaged here by the NASA/ESA Hubble Space Telescope. This is a barred spiral galaxy with two arms that twist out into the universe. This galaxy is ...

Astronomers could spot life signs orbiting long-dead stars

The next generation of powerful Earth- and space-based telescopes will be able to hunt distant solar systems for evidence of life on Earth-like exoplanets—particularly those that chaperone burned-out stars known as white ...

Star survives close call with a black hole

Astronomers may have discovered a new kind of survival story: a star that had a brush with a giant black hole and lived to tell the tale through exclamations of X-rays.

Seeing the light: Study finds new way novae light up the sky

A nova, or stella nova, the Latin word for "new star," is an explosion on the surface of a star that can produce enough energy to increase the star's brightness by millions of times. Sometimes a nova, which occur in stars ...

Two stars merged to form massive white dwarf

A massive white dwarf star with a bizarre carbon-rich atmosphere could be two white dwarfs merged together according to an international team led by University of Warwick astronomers, and only narrowly avoided destruction.
