James Webb discovers earliest sign of the Universe becoming transparent

The first galaxies in the Universe were born enshrouded in a “foggy” gas, and could not be seen clearly until they had cleared up this fog. Using the James Webb Space Telescope, a team of researchers led by astronomers…

Galaxies do not affect black hole spectroscopy

When a black hole is disturbed, it “rings” like a bell before settling down - a phenomenon known as black hole ringdown. The study of the vibration modes of black holes is called spectroscopy, in analogy with atomic…

European Research Award to Johan Samsing

Johan Samsing receives the European MERAC award 2025 for "Best Early Career Researcher" from the European Astronomical Society for his groundbreaking contribution to Gravitational Wave Astrophysics.

“Super-Earth” in planetary system shedding new light on planetary evolution

An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, including an ultra-short period planet with one of the highest densities ever measured.

New insights into galaxy growth and dark matter from James Webb

An international team of researchers, led by astronomers at the Cosmic Dawn Center in Copenhagen, has released a comprehensive study on how galaxies and their dark matter have evolved across most of the history of the…

Webb provides a new detailed look into the formation of the first galaxies

An international team of researchers, led by astronomers at the Cosmic Dawn Center in Copenhagen, have published the first, large-scale study of more than 600 galaxies observed within the first billion years after the…

Dance of electrons measured in the glow from exploding neutron-stars

The temperature of elementary particles have been observed in the radioactive afterglow following the collision of two neutron stars and the birth of a black hole, and for the first time, made it possible to measure the…

"Islands" of Regularity Discovered in the Famously Chaotic Three-Body Problem

When three massive objects meet in space, they influence each other through gravity in ways that evolve unpredictably. In a word: Chaos. That is the conventional understanding. Now, a researcher from the University of…

Black Hole Week at NBI

This August we are celebrating black holes in Copenhagen! There are many reasons to be excited. We celebrate 50 years of Hawking radiation, and since that seminal work, so much has happened.
