Cosmic grains of dust formed in supernova explosion

09. juli 2014

Cosmic grains of dust formed in supernova explosion New research from the Niels Bohr Institute at the University of Copenhagen and Aarhus University shows that not only can grains of dust form in gigantic supernova explosions, they can also survive the subsequent shockwaves they are

New insights into gamma-ray Burst afterglows

30. april 2014

New insights into gamma-ray Burst afterglowsGamma-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 that can be

Cosmic collision creates mini-planet with rings

26. marts 2014

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 the first

Stream of stars in Andromeda satellite galaxy shows cosmic collision

23. februar 2014

Stream of stars in Andromeda satellite galaxy shows cosmic collisionThe 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.

Explosive growth of young star

04. december 2013

New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now

Monster gamma-ray burst in our cosmic neighbourhood

21. november 2013

Gamma-ray bursts are violent bursts of gamma radiation associated with exploding massive stars. For the first time ever, researchers from the Niels Bohr Institute, among others, have observed an unusually powerful gamma-ray

Quasar observed in 6 separate light reflections

07. august 2013

Using a special method where you observe light that has been bent by gravity on its way through the universe, a group of physics students from NBI have observed a quasar whose light has been deflected and reflected in
