Apr. 4, 2025 Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing 10 times brighter than the ...
Apr. 2, 2025 For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery ...
Apr. 2, 2025 In new images, scientists have gotten the closest look yet at Sagittarius C -- a 'stellar nursery' where clouds of gas and dust have collapsed to form thousands of new ...
Mar. 13, 2025 At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts -- caused by the death of a massive star -- may ...

Mar. 10, 2025 Astronomers have peered back to a time when the universe was just less than 300 million years old. The research team, using JWST revealed something ...
Mar. 10, 2025 A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark ...
Feb. 27, 2025 Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don't ...
Feb. 20, 2025 Researchers have found that stars in the early universe may have formed from 'fluffy' molecular clouds. Using the ALMA telescope to observe the Small Magellanic Cloud -- whose environment is similar ...
Feb. 19, 2025 Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and ...

Feb. 4, 2025 NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf ...
Jan. 29, 2025 Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...
Jan. 21, 2025 Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young ...
Jan. 21, 2025 Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old ...
Jan. 17, 2025 In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby ...
Jan. 16, 2025 Leo P, a small galaxy and a distant neighbor of the Milky Way, is lighting the way for astronomers to better understand star formation and how a galaxy grows. Scientists have reported finding that ...
Jan. 16, 2025 Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same ...
Jan. 15, 2025 For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 ...
Jan. 15, 2025 By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from ...

Jan. 6, 2025 Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present ...
Jan. 6, 2025 Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky ...
Jan. 3, 2025 Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that ...
Dec. 20, 2024 Researchers have found evidence of magnetic fields associated with a disc of gas and dust a few hundred light-years across deep inside a system of two merging galaxies known as Arp220. They say these ...
Dec. 18, 2024 Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut ...
Dec. 17, 2024 An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...
Dec. 13, 2024 The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the ...
