Colliding neutron stars provide a new way to measure the expansion of the Universe

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…

New Ph.D.: Plugging numbers into a formula isn't physics 

When students view physics formulas only as mathematical tools, they fail to understand physics in a meaningful way. We need to teach students to ask why, says new Ph.D.

Galakser der skygger for lyset Hvis en galakse tilfældigvis ligger langs sigtelinjen mod en fjernere, klar lyskilde, vil galaksen “skygge” for lyskilden og absorbere noget af dens lys. Denne absorption skyldes de gas- o…

A galaxy group in the early Universe

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.

Copenhagen’s safest bets for a dry weather bike ride

You have a 25% greater risk of cycling in the rain if you live in Hellerup than if saddling up in Ishøj. Two researchers from the University of Copenhagen and DTU took a closer look at where and when it rains most in an…

Strong art residency: selected artists

Art and science are different ways of expressing our human curiosity and our will to understand the cosmos. This often means dealing with the unknown. The Strong team at the Niels Bohr Institute invited proposals for…
