Galaxies

The James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday.

Astronomers identified the largest stellar black hole yet discovered in the Milky Way, with a mass 33 times that of the Sun, according to a study published on Tuesday.

For astronomers peering into the depths of the universe, Christmas came a little early this year.

Astronomers have discovered the most distant black hole yet using the Webb Space Telescope, but that record isn't expected to last.

The black hole is at the center of a galaxy dating to within a mere 570 million years of the Big Bang. That's 100 million years closer to the beginning of the cosmos than a black hole identified in 2021 by a Chinese team using a telescope in Chile.

On Wednesday evening, an international consortium of research collaborations revealed compelling evidence for the existence of a low-pitch hum of gravitational waves reverberating across the universe.

Astronomers said on April 26 that for the first time they have confirmed what ignites quasars, the brightest and most powerful objects in the universe, which put galaxies in their "death throes."

These celestial behemoths form when two galaxies smash into each other, the astronomers said, warning that this could be the Milky Way's fate in a few billion years.

One of the largest black holes ever recorded has been discovered using a new technique that could spot thousands more of the insatiable celestial monsters in the coming years, according to astronomers.

The ultramassive black hole, one of just four ever observed, is more than 30 billion times the mass of the Sun, a new study said.

A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect
