Ink from ancient Egyptian papyri contains copper

Until recently, it was assumed that the ink used for writing was primarily carbon-based at least until the fourth and fifth centuries AD. But in a new University of Copenhagen study, analyses of 2,000-year-old papyri…

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.

New generation ESA-satellites capable of revealing future sea level rises

NEGIS, the Northeast Greenland Ice Stream, splits into three gigantic glaciers - holding back ice masses equaling a global sea level rise of approx. one meter. ESA satellites can help reveal future sea increases.
