Wolk Just when astronomers think they're starting to understand stellar activity , something strange grabs their attention . That's the case with a newly discovered stellar object called ASKAP J1832-0911. It lies about 15,000 light-years from Earth and belongs to a class of stellar objects called long-period radio transients . quot That means it emits radio waves that vary in their

A team of geophysicists from the University of Chicago showed how clouds on exoplanets could enhance the search for biosignatures. Their findings could have significant implications for the Habitable Worlds Observatory (HWO) and other next-generation telescopes that will study exoplanets via direct imaging.

The galaxy cluster Abell S1063 dominates the center of this JWST image. It's a massive cluster of galaxies about 4.5 billion light-years away. While it dominates the picture, it's not the primary target. It serves as a gravitational lens that magnifies even more distant galaxies that appear as glowing streaks of light around its circular edges.

Modern ground-based telescopes rely on adaptive optics (AO) to deliver clear images. By correcting for atmospheric distortion, they give us exceptional pictures of planets, stars, and other celestial objects. Now, a team at the National Solar Observatory is using AO to examine the Sun's corona in unprecedented detail.

System By Mark Thompson May 27, 2025 Illustration of the strange system Binary star systems are pairs of stars held together by gravity , orbiting a common center of mass . More than half of all stars in our Galaxy are part of a binary or multiple-star system making them surprisingly common . The stars in a binary can vary widely in mass , size , and brightness , and their interactions often shape their evolution in dramatic ways . In some cases , the gravity from one star can drag material from its companion , leading to explosive events like novae or even supernovae . Studying binary systems not only helps us to understand the life cycle of stars but also

Astronomers with the Event Horizon Telescope have developed a new way to observe the radio sky at multiple frequencies, and it means we will soon be able to capture color images of supermassive black holes.

Credit ESA ASI University of Melbourne Multi-messenger astronomy has been all the rage lately . It involves capturing data on the gravitational and electromagnetic signals from catastrophic cosmic events . However , with that newfound interest comes required updates to infrastructure . Gravitational wave detectors have been upgraded and will be even more sensitive soon . But to realize the promise of multi-messenger astronomy , scientists must have a fleet of spacecraft watching the entire sky for high-energy signals indicative of the events that cause gravitational waves .
