New telescopes to study the aftermath of the Big Bang

Astronomers are currently pushing the frontiers of astronomy. At this very moment, observatories like the James Webb Space Telescope (JWST) are visualizing the earliest stars and galaxies in the universe, which formed during ...

Billion-light-year-wide 'bubble of galaxies' discovered

Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard.

How could we detect atom-sized primordial black holes?

One of the most intriguing predictions of Einstein's general theory of relativity is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can escape them.
