Using the Hubble Space Telescope (HST) and the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have performed a multiwavelength study of a symbiotic binary known as HM Sagittae. Results of the study, ...
Using the United Kingdom Infrared Telescope (UKIRT) and NASA's Spitzer Space Telescope, astronomers have conducted photometric observations of a nearby star-forming galaxy known as NGC 6822. They have identified nearly 3,000 ...
(Phys.org)—Astronomers have detected a new metal-poor, luminous post-asymptotic giant branch star in the Small Magellanic Cloud. The newly found object, designated J005252.87-722842.9, appears to have undergone an unusual ...
Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve ...
