James Webb’s “too massive” galaxies may be even more massive

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.

Nearby galaxies help astronomers understand distant galaxies

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…

First ever asteroid hit by spacecraft could save the Earth from impact

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…

The brightest explosion ever seen

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.

Intergalactic gas brings supermassive black holes at the heart of galaxies to life

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…

Astrophysicists discover the perfect explosion in space

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…

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.
