From deep under the Antartica-surface: IceCube has collected new knowledge about high-energy neutrino physics

High-energy neutrinos ‘caught’ in Antarctica Scientists from NBI were part of an international team measuring neutrino interaction at energy levels 1000 times higher than what can be attained in man-made particle…

Anja C. Andersen has been awarded the Danish Authors' Society Literary Prize 2017

The prize has previously been awarded, among others, to Ebbe Kløvedal Reich, Tor Nørretranders, Jørn Lund, Peter Øvig Knudsen, Jens Andersen, Ulrik Langen and Søren Ryge. This year, the prize is shared between Anja C.…

New discovery: Supernova explodes several times

Astronomers have for the first time discovered a star that exploded multiple times over a period of more than fifty years. These observations are challenging existing theories on cosmic catastrophes.

Neutron star smash shakes universe

Scientists have, for the first time, captured gravitational waves as well as light, from two neutron stars that orbited each other ever closer to eventually collide. The groundbreaking discovery begins a...

Neutronstjerners sammenstød rystede universet

For første gang er det lykkedes at opfange tyngdebølger såvel som lys fra to kolliderende neutronstjerner. Den banebrydende opdagelse indleder en helt ny æra inden for astronomien.

Astronomerne har fået en ekstra sans

Nu er det for første gang lykkedes at detektere tyngdebølger såvel som elektromagnetiske stråling fra det samme objekt. Vi har fået en ny sans, så vi nu også kan opfatte tyngdeverdenen, vi kan både se og høre universet.

Now we can find out where the heavy elements come from

The discovery of a kilonova produced by the collision of two neutron stars brings researchers a big step closer to the explanation of one of the great puzzles of science: how the heaviest elements in the universe were…

Nu er det bevist: Her kommer de tunge grundstoffer fra

Opdagelsen af en kilonova fremkommet ved sammenstødet mellem to neutronstjerner bringer forskerne et stort skridt nærmere opklaringen af en af videnskabens store gåder: Hvordan de tungeste grundstoffer i universet er…

Sådan gjorde de: Den største astronomiske opdagelse i nyere tid

En videnskabelig sensation kom i hus, da tusindvis af forskere samarbejdede om at måle tyngdebølger og lys fra sammenstødet mellem to neutronstjerner 140 millioner lysår væk.

ALMA and Rosetta Detect Freon-40 in Space

Observations made with ALMA and ESA’s Rosetta mission by an international team, including researchers from NBI, have revealed the presence of the organohalogen Freon-40 in gas around both an infant star and a comet.

Star formation influenced by local environmental conditions

Three scientists at Niels Bohr Institute (NBI), University of Copenhagen, have carried out extensive computer simulations related to star formation, and they conclude that the present ‘standard explanatory model’ is…

At the age of 85-year old, Erik Høg is planning a satellite to be launched in 20 years

Erik Høg, who celebrated his 85th birthday earlier this year, has just had his fourth major astrometry project approved, a project that he started in 2013 and one that ESA is now joining. A satellite that will be…

ALMA Finds Ingredient of Life Around Infant Sun-like Stars

Astronomers, including researchers from the Niels Bohr Institute, have used ALMA to observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate — a chemical building block…

Newly formed stars shoot out powerful whirlwinds

Researchers from the Niels Bohr Institute have used the ALMA telescopes to observe the early stages in the formation of a new solar system. For the first time they have seen how a powerful whirlwind shoot out from...

Mystery of ultra-diffuse faint galaxies solved

Over the last year, researchers have observed some very faint, diffuse galaxies. The galaxies are as faint as dwarf galaxies, but are distributed over an area just as large as the Milky Way.
