Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented ...
Using the Himalayan Chandra Telescope (HCT) and ESA's Gaia satellite, Indian astronomers have conducted a comprehensive study of a young open cluster designated NGC 2345. Results of the study, presented March 7 on the preprint ...
Betelgeuse is the well known red giant star in the corner of Orion the hunter. The name translated in some languages means "armpit of the giant," which, I think of all the star names, is simply the best! Betelgeuse has been ...
