Cosmic grains of dust formed in supernova explosion

New research published in Nature shows that not only can grains of dust form in gigantic supernova explosions, they can also survive the subsequent shockwaves they are exposed to. Led by researchers from Aarhus and DARK

New insights into gamma-ray Burst afterglows

Gamma-ray bursts are powerful bursts of gamma radiation in connection with the explosive death of massive stars. The bursts themselves are short lived – typically less than a few minutes, but is followed by an afterglow…

Cosmic collision creates mini-planet with rings

Until now, rings of material in a disc have only been observed around giant planets like Jupiter, Uranus, Neptune and especially Saturn, which is known for its spectacular rings. Now astronomers from NBI, have observed…

Johan Samsing receives the prestigious Einstein Fellowship

Johan Samsing, who is just about to complete his PhD at Dark Cosmology Centre at the Niels Bohr Institute, has just been awarded one of the most prestigious research fellowships in astrophysics, the so-called ‘Einstein…

Stream of stars in Andromeda satellite galaxy shows cosmic collision

The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from NBI, among others, have detected a stream of stars in one of the Galaxy’s outer satellite galaxies, called Andromeda II.

First images of star cluster from the Gaia Satellite

The Gaia Satellite has already sent its first images down to Earth approximately 40 days after its launch on the 19th of December. They show a dense collection of stars in the Large Magellanic Cloud at a distance of…

Early galaxies grew massive through collisions

New research from the Niels Bohr Institute shows that massive galaxies were formed by explosive star formation that was set in motion by the collision of galaxies a few billion years after the Big Bang
