Exiled stars explode 'far' from home

 Sharp images obtained by the Hubble Space Telescope has confirmed that three supernovae discovered several years ago exploded in the dark emptiness of intergalactic space, after being flung from their home galaxies millions or billions of years earlier.

Supernova hits star, reveals its origin

A team of astronomers has witnessed a supernova smashing into a nearby star, shocking it and creating an ultraviolet glow that reveals the size of the companion.

Research reveals universe's most powerful explosions

Gamma-ray bursts (GRBs) in the universe are rare explosions that happen when extremely massive stars go supernova. A study provides an inside look at the most powerful explosions in the universe.

Hubble sees supernova split into four images

 Astronomers using NASA's Hubble Space Telescope have spotted for the first time a distant supernova split into four images by cosmic lens.

Astronomers view four images of a supernova, in a first

Finnish researchers have discovered a new type of low-mass black hole, which is a bright celestial body that emits X-ray, the University of Turku has said.

First hydrogen-deficient supernova progenitor traced

In a finding that may have important implications for the evolution of massive stars, a group of researchers presented a model that provides the first characterisation of the progenitor (parent) of a hydrogen-deficient supernova.

Study provides deeper insight into `spectacular` Type la supernova

A new study has helped astronomers to solve the mysteries related to the spectacular supernova in a galaxy 11 million light years away, seen earlier in 2014.

Scientists recreate supernova in lab

Researchers used laser beams 60,000 billion times more powerful than a laser pointer to recreate scaled supernova explosions in the laboratory as a way of investigating one of the most energetic events in the Universe.

Astronomers using supernovae to measure distant objects

Supernovae or exploding stars observed by NASA`s Hubble Space Telescope are providing astronomers a powerful tool to determine the strength of naturally-occurring `cosmic lenses`.

Supernova that swept materials equivalent to about 45 times sun`s mass found

Researchers have identified a supernova remnant - known as G352.7-0.1 (or, G352 for short) - that has swept material, equivalent to about 45 times the mass of the Sun.

Closest `standard candle` supernova of nearby galaxy observed in decades

Less than 12 million light-years away, the Supernova 2014J in the nearby galaxy M82, which exploded on January 14, 2014, was the closest "standard candle" supernova in 42 years.

How supernova looks like before its death

A powerful, new three-dimensional model has provided fresh insight into the turbulent death throes of supernovas.

Closest, brightest supernova poses new questions about exploding stars

A bright supernova found only six weeks back in a nearby galaxy is provoking new questions about the exploding stars , which researchers use as their main yardstick for measuring the universe.

Scientists discover new supernova just 12 million light-years away

An optical supernova, designated SN 2014J , which occurred in the galaxy M82 and lies only about 12 million light-years away, has attracted the attention of many space agencies, including NASA.

Closest supernova to Earth discovered near Messier 82 galaxy

Students and staff at UCL`s teaching observatory, the University of London Observatory, have spotted one of the closest supernova to Earth in nearby galaxy Messier 82 (the Cigar Galaxy).
