A novel way of investigating star-forming gas in the early Universe

Combining observations of exploding stars and observations of galaxies, astronomers at the Cosmic Dawn Center have found a novel way to estimate the amount of the otherwise invisible, cold gas in some of the first…

One in five galaxies in the early universe could still be hidden behind cosmic dust

Astronomers at the University of Copenhagen’s Cosmic Dawn Center have discovered two previously invisible galaxies billions of light-years away. Their discovery suggests that up to one in five such distant galaxies…

Reported record-distant explosion turns out to be probably just a piece of space junk

A perspective into how science sometimes operates: Even with the most careful measures taken to ensure the validity of a scientific result, every so often some results are bound to turn out to be mistaken or inaccurate.…

UCPH astronomers find six distant – and mysteriously dead – galaxies

Astronomers from the University of Copenhagen and the Technical University of Denmark (DTU), among others, have peered back 10-12 billion years into the universe and found six galaxies that mysteriously ran out of gas…

Astronomers see the same supernova three times — and predict a fourth to appear in 16 years

The enormous gravitation of a cluster of galaxies warps space to the extent that light from distant galaxies is deflected and brought to us from multiple directions. This effect has enabled astronomers from the…
