As scientists refine their methods, exoplanets are becoming easier and easier to detect. The current count is 163 planets orbiting 97 main-sequence stars, of which only one is even remotely Earth-like. All the others are ...
Using the Very Large Telescope (VLT) in Chile, astronomers have observed the halo of a nearby giant elliptical galaxy known as Centaurus A. Results of the observational campaign, published June 1 on the pre-print server arXiv, ...
Chinese astronomers report the discovery of a new high-velocity star about 4,200 light years away. The newfound star, designated J0731+3717, turned out to be ejected from the globular cluster Messier 15 by an intermediate-mass ...
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station, astronomers have observed a distant X-ray binary known as EXO 2030+375. The observational campaign allowed them to explore ...
