The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc…

Maggie Aderin-Pocock never imagined she’d become one of the United Kingdom’s most famous scientists. Best known for co-hosting the BBC’s astronomy TV program “The Sky at Night,” the space scientist and broadcaster rose from unlikely circumstances to pursue her dreams. Growing up with dyslexia in government housing in London, Aderin-Pocock went on to study physics…

WASHINGTON — The first satellites of a Chinese broadband constellation are significantly brighter than those of Western systems, posing a new challenge for astronomers. In a paper posted on the arXiv preprint server Sept. 30, a group of observational astronomers reported on observations of a set of 18 Qianfan, or “Thousand Sails,” satellites launched in…

Using the James Webb Space Telescope (JWST), astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface of Pluto’s largest moon, Charon. Detecting these molecules could tell scientists how Charon and other icy bodies at the solar system’s edge were born. Since its discovery in 1978, Charon has been extensively studied — but…

image:  This artist’s impression of a planet-forming disk surrounding a young star shows a swirling “pancake” of hot gas and dust from which planets form. Using the James Webb Space Telescope, the team obtained detailed images showing the layered, conical structure of disk winds – streams of gas blowing out into space. view more  Credit:…

Nested morphology of gas streams confirms a mechanism that helps infant stars to grow by ingesting disk material. Planet-forming disks, maelstroms of gas and dust swirling around young stars, are nurseries that give rise to planetary systems, including our solar system. Astronomers have discovered new details of gas flows that sculpt and shape those disks…

Cosmos, in astronomy, the entire physical universe considered as a unified whole (from the Greek kosmos, meaning “order,” “harmony,” and “the world”). Humanity’s growing understanding of all the objects and phenomena within the cosmic system is explained in the article universe. For a history of the study of the universe as a unified whole, see…

Using the James Webb Space Telescope, astronomers have captured a stunning image of a distant supernova in a galaxy that looks like it’s being stretched like warm taffy. However, the golden smear hiding this gravitationally lensed supernova, which has been nicknamed “supernova Hope,” isn’t just remarkable for its aesthetic value. The supernova, which exploded when…

October is giving Hoosiers a chance to see possibly the brightest comet of 2024, according to NASA, before it fades away into the outer edge of our solar system where it won’t return in our lifetime. A comet named C/2023 A3 Tsuchinshan–ATLAS is making an 80,000-year orbit around the sun. Some have dubbed it the…

Scientists are studying whether future astronauts on deep-space journeys could transform compounds in asteroids into food. Astronauts embarking on long-haul journeys in deep space can’t pack all the calories they will need in the form of freeze-dried food. They also can’t grow everything they’ll need, as onboard garden technology isn’t mature enough to keep them…
