The first direct mass measurement from the early universe weighs in on the debate over the origins of supermassive black holes.

Scientists using data from the James Webb Space Telescope have made one of the most detailed high-resolution maps of dark matter ever produced. It shows how the invisible, ghostly material overlaps and intertwines with ‘regular’ matter, the stuff that makes up stars, galaxies, and everything we can see.

Astronomers have spotted one of the oldest ‘dead’ galaxies yet identified, and found that a growing supermassive black hole can slowly starve a galaxy rather than tear it apart.

Astronomers using the James Webb Space Telescope (JWST) have captured the most detailed look yet at how galaxies formed just a few hundred million years after the Big Bang – and found they were far more chaotic and messy than those we see today.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just four light-years away from Earth, the Alpha Centauri triple star system has long been a target in the search for worlds beyond our solar system.

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

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.
