A a team of researchers including astronomers from the Niels Bohr Institute has used the James Webb Space Telescope to study a gamma-ray burst, which turned out to be the second-brightest ever seen.

In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now…

With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created.

Contrary to typical observations, the galaxy was discovered not by the light it emits, but by the light it absorbs. The galaxy itself evades observations, but has at least one nearby companion.

The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the Universe.

In a newly published study researchers show how the amount of light that escapes from a galaxy is connected to its physical properties. The result has implication for how we interpret observations of galaxies in the…

Humanity’s first attempt to re-direct asteroids that could collide with Earth, the NASA Double Asteroid Redirection Test satellite (DART), successfully impacted the 150 meter large moon Dimorphos orbiting the 760 m…

A particularly bright Gamma-ray burst was recently detected by several space telescopes, and a team of scientists led by astronomers at the Cosmic Dawn Center measured the exact distance to the burst.

Black holes become active and grow by consuming gas captured from other galaxies. This is the finding of a new study from University of Copenhagen researchers, and shows a clear connection between the evolution of…

When neutron stars collide they produce an explosion that, contrary to what was believed until recently, is shaped like a perfect sphere. Although how this is possible is still a mystery, the discovery may provide a new…

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…

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.
