The prolonged death of light from type Ia supernovae

Three years after its explosion, a type Ia supernova continues to shine brighter than expected, new research finds. The observations, made with the Hubble Space Telescope and published today in The Astrophysical Journal, ...

Prawn Nebula: Cosmic recycling

Dominating this image is part of the nebula Gum 56, illuminated by the hot bright young stars that were born within it. For millions of years stars have been created out of the gas in this nebula, material which is later ...

Image: Multicoloured view of supernova remnant

Most celestial events unfold over thousands of years or more, making it impossible to follow their evolution on human timescales. Supernovas are notable exceptions, the powerful stellar explosions that make stars as bright ...

Dark Energy Survey spots exotic supernova

(Phys.org) —The first images taken by the Dark Energy Survey (DES) after the survey began in August 2013 have revealed a rare, 'superluminous' supernova that erupted in a galaxy 7.8 billion light years away. The stellar ...

A 3-D model of stellar core collapse

(Phys.org) —What happens when massive stars collapse? One potential result is a core-collapse supernova. Astronomers can make observations of such events that tell us what is happening on the surface of a star when it explodes ...

Image: Starbursting in the galaxy M82

(Phys.org) —Messier 82 (M82), the galaxy in which the nearest supernova in decades recently exploded, also is the closest galaxy that is undergoing a rapid burst of star formation, known as a starburst. About 12 million ...

Astronomers reveal mystery of brightest ever gamma-ray burst

For the first time, a team of astronomers from around the world, including experts from the University of Leicester, have used data from satellites and observatories to explain the brightest Gamma-ray Burst (GRB) ever recorded.

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 known as ...
