Webb observes the glowing embers of colliding neutron stars

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.

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…

Astronomers discover newborn galaxies with the James Webb Space Telescope

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.

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.
