Using the radial velocity (RV) method, an international team of astronomers has discovered two new exoplanets transiting a nearby M-dwarf star known as GJ 1002. The newfound alien worlds have masses similar to that of our ...
Thanks to the James Webb Space Telescope's first images of galaxy clusters, researchers have, for the very first time, been able to examine very compact structures of star clusters inside galaxies, so-called clumps. In a ...

An international team of astronomers reports the detection of a rare eclipsing Be/X-ray binary system as part of the Swift Small Magellanic Cloud (SMC) Survey (S-CUBED). The finding was detailed in a research paper published ...
Despite their ancient ages, some stars orbiting the Milky Way's central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these ...
