4+ day, 1+ hour ago   (231+ words) Astronomers have reconstructed a massive protostellar encounter that could reveal an unexpected route to building close binary stars. Astronomers have reconstructed the turbulent assembly of two massive young stars, finding evidence that they may have formed separately before a close…...

5+ day, 40+ min ago   (522+ words) This strange cosmic structure looks like a giant eye in space, but astronomers discovered that the Helix Nebula is actually a massive cylinder of glowing gas pointing toward Earth. A new portrait of the Helix Nebula offers one of the…...

1+ week, 22+ hour ago   (166+ words) New ALMA images expose persistent hot spots in Betelgeuse's changing atmosphere, and a nearby companion may help explain their unusual alignment. New high-resolution observations of Betelgeuse reveal an increasingly patchy and asymmetric inner atmosphere, with a persistent pattern that may…...

1+ week, 1+ day ago   (508+ words) Giant planets do not have unlimited time to take shape. New JWST observations reveal what is happening around young stars while these massive worlds are still forming. Gas giants may have far less time to form than their enormous size…...

1+ week, 2+ day ago   (654+ words) Astronomers have identified the violent merger that launched a supermassive black hole out of its galaxy and into intergalactic space. In 2022, astronomers detected an unusual structure extending from a distant galaxy located about 7.5 billion light-years from Earth. The feature appeared…...

1+ week, 2+ day ago   (507+ words) NASA’s latest rocket mission reveals the hidden complexity of atmospheric clouds that can disrupt radio signals and GPS accuracy. NASA has captured the first multi-point view inside sporadic E layers, revealing that these mysterious ionospheric clouds have complex structures that…...

1+ week, 3+ day ago   (345+ words) A telescope’s biggest enemy may soon be defeated. This new camera copies the human eye to spot satellites before they ruin stunning deep-space images. As more spacecraft are launched into low Earth orbit, they increasingly pass through the same patches…...

1+ week, 5+ day ago   (710+ words) James Webb observations may have revealed the distant galaxy behind a mysterious gamma-ray burst that puzzled astronomers for nearly 20 years. A nearly 20-year-old mystery surrounding the unusual gamma-ray burst GRB 061201 may have been resolved after observations from the James Webb…...

1+ week, 5+ day ago   (632+ words) JWST has found evidence of a cosmic race happening around young stars, but the full impact on planet formation remains a mystery. NASA’s James Webb Space Telescope (JWST) has revealed that young planetary systems lose their gas through different processes…...

2+ week, 17+ hour ago   (312+ words) Astronomers may have identified the strongest candidate yet for a galaxy made almost entirely of gas with no stars. Team leader Ignacio Trujillo of the Instituto de Astrofísica de Canarias in Spain described the significance of the observation to Space....
