New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole ...

A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the ...

Chinese astronomers have spotted a hidden supermassive black hole in the background of a peculiar gravitational wave event from a black hole merger, hinting that all three singularities were locked in ...

And although it has the highest radius of all the stars, it is not actually the most massive, as UY Scuti is about 30 times the weight of our sun, a stark reminder that you can't judge a star entirely ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

For the first time, scientists measured a newborn black hole that "kicked" off into space after 2 larger black holes merged together.

Some astronomers think one set of measurements or the other will turn out to be wrong. Others believe that the tension is a hint of deeper problems with the scientific description of the universe, ...

Astronomers have discovered what is claimed to be the oldest confirmed black hole in the universe, providing a glimpse into the early stages of cosmic history when the universe was only 3% of its ...

Just 500 million years after the Big Bang, a colossal black hole, 300 million times the mass of the Sun, was already blazing at the heart of a tiny, brilliant galaxy. Found with JWST, this discovery ...
