Super-bright supernova with extreme burst of gamma radiation

Astronomers from NBI have observed a super-bright supernova association with a very unusual long lasting gamma-ray burst. Gamma-ray bursts are in rare cases observed in connection with supernovae, which are the

Mars might have liquid water

Researchers have long known that there was water in the form of ice on Mars. Now, new research from NASA’s Mars rover Curiosity shows that it is possible that there is liquid water close to the surface of Mars.

Anja Andersen gives this year's Rosseland Lecture

April 8th 2015, Anja Andersen gave this year's Rosseland lecture about her research at DARK about cosmic dust in the interstellar medium. The Rosseland Lecture is held annually by the Institute of Theoretical…

Mars has belts of glaciers consisting of frozen water

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the…

Planets in the habitable zone around most stars, calculate researchers

Astronomers have discovered thousands of exoplanets in our galaxy, the Milky Way. By analysing these planetary systems, researchers from the Australian National University and the Niels Bohr Institute in Copenhagen have…

Astronomers observe four images of the same supernova using a cosmic lens

Astronomers have for the first time observed a supernova multiply-imaged due to gravitational lensing. The light from the supernova is seen in four different images due to a cosmic phenomenon that causes light to be…

Astronomers have for the first time observed a supernova multiply-imaged due to gravitational lensing. It is published in the scientific magazine Science in a special issue celebrating the centenary of Einstein’s Theory…

Astronomers find dust in the early universe

Dust plays an extremely important role in the universe – both in the formation of planets and new stars. But the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from…

Two researchers at the Niels Bohr Institute receive large ERC grants

Two researchers in astrophysics - Sune Toft, associate professor at the Dark Cosmology Centre and Jes Jørgensen, associate professor in Astrophysics and Planetary Science have each received 15 million kroner (approx. 2…

Snapshot of cosmic burst of radio waves

A strange phenomenon has been observed by astronomers right as it was happening – a ‘fast radio burst’. The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe.

Using supermassive black holes to measure cosmic distances

One of the major problems in astronomy is measuring very large distances in the universe. Research from DARK shows that precise distances can be measured using supermassive black holes. The results are now published in…

Using supermassive black holes to measure cosmic distances

One of the major problems in astronomy is measuring very large distances in the universe. The current most common methods measure relative distances, but now research from the Niels Bohr Institute demonstrates that…
