Could an alien mothership be hovering around the solar system, sending out tiny probes to explore planets? According to a Harvard scientist and a Pentagon official, it’s possible. In a draft paper, the pair said it is feasible an extraterrestrial spaceship could be in our galactic neighborhood, exploring the region by the means of “dandelion … Read more
The universe could, in fact, be a giant doughnut, despite all of the evidence suggesting it’s as flat as a pancake, new research suggests. Strange patterns found in echoes of the Big Bang could be explained by a universe with a more complicated shape, and astronomers have not fully tested the universe’s flatness, the study … 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
Astronomers studying a remote baby star have found a “missing link” that could finally explain the origins of water on Earth, a new study suggests. By training a powerful radio telescope at V883 Orionis, a protostar 1,300 light-years away from Earth in the constellation Orion, astronomers have spotted gaseous water with a chemical composition close … 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
The first stars in the cosmos may have topped out at over 10,000 times the mass of the sun, roughly 1,000 times bigger than the biggest stars alive today, a new study has found. Nowadays, the biggest stars are 100 solar masses. But the early universe was a far more exotic place, filled with mega-giant … 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
