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.

Satellite photos reveal gigantic outburst floods

The lake has been the source of four major outburst floods over the last 50 years - each representing an astounding mass of energy, equaling up to 240 Hiroshima-bombs. The next may happen as soon as 2018-19.

Smart atomic cloud solves Heisenberg's observation problem

One of the most fundamental principles of physics, "Quantum Back Action", has been challenged by researchers from the Niels Bohr Institute, which has used laser light to link a vibrating membrane with cesium atoms.

Iron secrets behind superconductors unlocked

Due to magnetism iron should - theoretically - be a poor superconductor. Nevertheless certain ironbased materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron...

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…
