Planetary scientists have found groundbreaking evidence of recent volcanic activity on Venus. Archives from NASA’s Magellan mission show telltale signs that Maat Mons, a 5-mile-high (8 kilometers) volcano on Earth’s hellish twin, was active in 1991. Magellan, launched in May 1989, was the first spacecraft to map the entire surface of Venus. The mission’s radar … Read more
The James Webb Space Telescope (JWST) has captured a dazzling image of a star about to go supernova in a massive explosion. The picture, released by NASA on Tuesday (March 14), shows the star WR 124 in the middle of a spectacular cosmic cloud. As it goes supernova, the star, which is about 30 solar … Read more
The moon crashing into Earth may sound like an unrealistic doomsday scenario or the stuff of sci-fi disasters. But for some planets in other star systems, such catastrophic collisions may be common. New research published in the journal Monthly Notices of the Royal Astronomical Society uses computer simulations to show that collisions between exoplanets and … Read more
Glimpsed only occasionally at the hearts of massive clusters of galaxies, ultramassive black holes are some of the largest and most elusive objects in the universe. These black hole behemoths have masses exceeding that of 10 billion suns, making them far more monstrous than even the supermassive black holes found at the centers of galaxies … Read more
The shredded remnants of the first supernova ever recorded by humans — which appeared in the sky more than 1,800 years ago and vanished within eight months — rise from the cosmic grave in a stunning new image from the National Science Foundation’s NOIRLab. Tinged blood red and swirling around an invisible center of mass, … Read more
For the first time, astronomers have spotted enormous, galaxy-scale shock waves rattling the “cosmic web” that connects nearly all known galaxies. These cosmic waves could reveal clues about how the largest objects in the universe were sculpted. The discovery was made by stitching and stacking thousands of radio telescope images together, which revealed the soft … Read more
The asteroid Ryugu, which orbits the sun between Earth and Mars, contains many of the building blocks for life, a new analysis finds. The study, published Feb. 23 in the journal Science, is one of the first peeks at the samples from Ryugu brought back by Japan’s Hayabusa2 spacecraft in 2020. The mission is only … Read more
Researchers have finally pinpointed the likely origin of mysterious heartbeat-like signals spat out by the sun during solar flares. The findings could help us learn more about how potentially damaging solar storms are unleashed, a new study shows. Solar radio bursts are streams of electromagnetic radiation — made up mainly of radio waves, as well … Read more
If wormholes exist, they could magnify the light of distant objects by up to 100,000 times — and that could be the key to finding them, according to research published Jan. 19 in the journal Physical Review D. Wormholes are theoretical funnel-shaped portals through which matter (or perhaps spacecraft) could travel great distances. To imagine … Read more
Astronomers have spotted a runaway supermassive black hole, seemingly ejected from its home galaxy and racing through space with a chain of stars trailing in its wake. According to the team’s research, which was published April 6 in The Astrophysical Journal Letters (opens in new tab), the discovery offers the first observational evidence that supermassive … Read more
