Astronomers using data from the Euclid space telescope have discovered an exceptionally faint stellar system near the Fornax dwarf galaxy. Called Fornax-7, it appears to contain only about 170 times the mass of the sun […]

Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole appears to have launched powerful jets on four separate occasions. High-resolution observations with the […]

Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic […]

Could you imagine if pagers made a comeback? Sure, your smartphone would still be your notepad-flashlight-camera-personal assistant-MP3 player-wallet-social media browser. But imagine if pagers made it so easy to do that one important thing—pinging your […]

SKA-Low is a radio telescope under construction in Western Australia. It will operate across a wide frequency range, from 50 to 350 MHz, and will be the most sensitive telescope of its kind ever built. […]

Using the James Webb Space Telescope (JWST), a team of astronomers led by the University of Maryland identified water, methane and ammonia in the atmosphere of HATS-6 b, a giant planet 500 light-years from Earth. […]

The cosmic microwave background (CMB) is the universe’s oldest light, leftover thermal radiation from about 380,000 years after the big bang. Maps of the CMB offer a picture of the “baby universe” as it was […]

As a star nears the end of its life, it faces two very different fates: It can explode as a supernova, leaving behind a neutron star, or collapse and become a black hole. What determines […]

Astronomers have discovered a faint population of young stars extending far beyond the known edge of the nearby spiral galaxy Messier 74. The finding suggests the galaxy is nearly twice as large as previously measured. […]

Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to testing how ultralight, or “fuzzy,” dark matter could […]
