Could our location in space be skewing cosmic measurements? A new study suggests a giant void may explain the Hubble tension.

Observing this distant epoch is notoriously difficult, astronomers say. At that time, the universe was filled with a dense ...

Researchers aim to study the universe’s 'Dark Ages' using a quiet orbit around the Moon. Their small satellite will search ...

A team of astronomers have discovered a curious figure in the universe. It is two distant galaxies colliding with each other ...

A pair of galaxies whose light has traveled for 8.3 billion years contains what astronomers believe is a supermassive black ...

The earliest galaxies in the image appear as they did around 13.5 billion years ago, or approximately 0.3 billion years after the Big Bang, as that's how long their light has taken to reach the JWST.

The universe's age largely hinges on its rate of expansion. Data from the 1990s' Hubble Space Telescope launch saw estimates ranging from 7 billion to 20 billion years. It was only later that a ...

The James Webb Space Telescope, NASA’s biggest, most expensive and powerful telescope to date, was launched in December 2021 with the intention of spending five to 10 years studying a plethora ...
