New radio transients discovered with MeerKAT
Using the MeerKAT telescope in South Africa, an international team of astronomers has detected 26 new Galactic radio transients. Most of them turned out to be rotating radio transients (RRATs). The finding is detailed in ...
M87* observations catch the black hole's turbulent accretion flow
Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the supermassive black hole at the center of Messier 87 (M87*). This study marks a significant step ...

X-ray observations uncover merger process in a nearby low-mass galaxy cluster
Using NASA's Chandra and ESA's XMM-Newton spacecraft, an international team of astronomers have performed X-ray observations of a nearby low-mass galaxy cluster designated PSZ2 G181.06+48.47. The observational campaign, detailed ...
Extreme supersonic winds measured on a planet outside our solar system
Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet stream of its kind ever measured on a planet. ...
