Phys.org / JWST reveals most distant red galaxy yet at redshift 11.45
Using the James Webb Space Telescope (JWST), astronomers have discovered a new red galaxy at a redshift of approximately 11.45. The newfound galaxy, which received designation EGS-z11-R0, turns out to be the most distant ...
Phys.org / Hydrogen shell detected around Nova Persei 1901 may be a planetary nebula
Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...
Phys.org / JWST probes emerging young star clusters in nearby spiral galaxy NGC 628
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 628. Results of the observational campaign, published March 10 on the arXiv pre-print server, ...
Phys.org / DESI maps C-19, an extremely metal-poor Milky Way stellar stream
Using the Mayall 4-meter telescope at Kitt Peak National Observatory, an international team of astronomers has observed C-19—an extremely metal-poor stellar stream in the Milky Way's halo. Results of the observational campaign, ...
Phys.org / Astronomers discover long-period radio transient of unknown origin
Using the Australian SKA Pathfinder (ASKAP), astronomers have discovered a new long-period radio transient source, which received the designation ASKAP J142431.2–612611 (ASKAP J1424 for short). The newfound transient has ...
