Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?

If you want to build a habitable planet, ice, carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as…

Early galaxy formation caught in the act with James Webb

Astronomers from the Cosmic Dawn Center have unveiled the nature of the densest region of galaxies seen with the James Webb Space telescope in the early Universe.

Master student discovers a group of galaxies clustered together in the early Universe

While developing and testing astronomical software on existing data, a master student in astronomy fortuitously discovered a group of galaxies in the very early Universe.

Astronomers discover a swarm of galaxies orbiting a hyper-luminous galaxy

Using the Very Large Telescope and the radio telescope ALMA in Chile, a team of astronomers including researchers from the Niels Bohr Institute has discovered a swarm of galaxies orbiting the surroundings of a…

Martian oxygen factory passes first major test

New results from the red and rocky surface of Mars have shown that MOXIE, an oxygen generator that Danish researchers from the University of Copenhagen and fellow institutions have been deeply involved with, has passed…

New method to map the surface of the moon increases accuracy to unprecedented levels

This new method uses a much more direct and precise calculation, it doesn’t rely on a whole set of parameters to be fed into the computer, and it can even calculate the uncertainties and the accuracy.

Compact, massive triple star system detected for the first time

How this unique combination of a binary set of stars and a revolving bigger star can form, is now the focus in a collaboration between two young researchers at the Niels Bohr Institute.

Radio- and microwaves reveal true nature of dark galaxies in the early Universe

Utilizing multiple radio telescopes across the world, a team of astronomers from the Cosmic Dawn Center, have discovered several galaxies in the early Universe that, due to massive amounts of dust, were hidden from our…

Free roaming black hole detected in our galaxy for the first time

Astronomers estimate that there should be 100 million black holes roaming among the 100 billion stars in our galaxy. They are the remnants of supernova explosions that happened throughout the 10 billion years of the…

Black holes helped quenching star formation in the early Universe

While some galaxies form stars at a continuous rate, others die out and lead a more passive life. What made these galaxies stop forming stars at an early age is not well established, not the least because they are so…
