Mystery of dwarf galaxy could be ejected black hole

Astronomers have observed a mysterious phenomenon, which could be a massive black hole that has been ejected into space in connection with two galaxies colliding. This may be due to gravitational waves from the…

The first telescope in the Danish led telescope network will be officially opened on 25 October, 2014 on Tenerife. This will launch a worldwide stellar research project that will bring us even closer to the stars and…

Comet headed for Mars

On Sunday evening, 19 October 2014 at 20:30, a comet will come closer to colliding with Mars than we have ever seen. When the comet, Siding Spring, was discovered in January 2013 it initially appeared that it might be o…

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…

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.
