Strongest hints yet of biological activity outside the solar system
17 April 2025Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

Astronomers have identified a bright hydrogen emission from a galaxy in the very early Universe. ̽»¨Ö±²¥surprise finding is challenging researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time.
Scientists have spotted a massive black hole in the early universe that is ‘napping’ after stuffing itself with too much food.
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the ‘inside-out’ growth of a galaxy in the early universe, only 700 million years after the Big Bang.
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars.
Astronomers have detected carbon in a galaxy just 350 million years after the Big Bang, the earliest detection of any element in the universe other than hydrogen.
̽»¨Ö±²¥two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the Big Bang, have been discovered using NASA’s James Webb Space Telescope (JWST), an international team of astronomers today announced.
An international team of astronomers, led by the ̽»¨Ö±²¥ of Cambridge, has used the James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the Universe was only 740 million years old. This marks the most distant detection of a black hole merger ever obtained and the first time that this phenomenon has been detected so early in the Universe.
A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers.
A team of astronomers, led by the ̽»¨Ö±²¥ of Cambridge, has used the NASA/ESA/CSA James Webb Space Telescope to reveal, for the first time, what lies in the local environment of galaxies in the very early Universe.
