Galaxies

Rohan Naidu was sitting at home with his girlfriend when he found the galaxy that nearly broke cosmology. As his algorithm dug through early images from the James Webb Space Telescope (JWST) late one night in July, Naidu shot to…

CAPE CANAVERAL, Fla. (AP) — The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all. Scientists released the shots Monday of the solar system’s biggest planet.The James Webb Space Telescopetook…

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious “stuff” permeates the universe. In particular, it exists in halos surrounding most galaxies. The mass of the halo exerts a strong…

Astronomers have created the largest ever 3D map of 1 million distant galaxies otherwise obscured by the Milky Way's dwarf galaxy neighbors, the Magellanic Clouds. The Magellanic Clouds are irregularly shaped galaxies that are a…

A team of astronomers have used the ALMA telescope to find a slowly-rotating galaxy in the early Universe. That galaxy is the youngest ever found with a measured rotation, and it's much slower than present-day galaxies.  All galaxies…

Well, this is the week for distant galaxies, isn’t it? Not only has JWST revealed some of the most distant ones ever seen in infrared, but other observatories are studying them, too. Astronomers at the Cosmic Dawn Center in Copenhagen…

About six months have elapsed since the most powerful space telescope in history bid farewell to Earth and took off into the darkness. In that time, the James Webb Space Telescope has deployed its gold-coated mirrors, turned on its…

Some galaxies, like the Milky Way, have maintained regular star formation for billions of years. Others, like large elliptical galaxies, are “red and dead.” Star formation in those galaxies shut off long ago. Astronomers have long…

Weeks after astronomers released a historic image of the Milky Way's supermassive black hole, Sagittarius A*, a separate study showed how it is probing the evolution of black holes in dwarf galaxies.A new analysis of dwarf galaxy…
