Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and ...
Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way's disk. Results of the study, detailed in a research paper published October 16 on the preprint server arXiv, yield ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted molecular line observations of a protostellar system known as VLA 1623. Results of the observational campaign, published June 18 on ...
An international team of astronomers has observed a high-redshift massive star-forming galaxy known as REBELS-25. They found that REBELS-25 is a dynamically cold disk galaxy. This finding was presented in a research paper ...
Kyushu University researchers have shed new light into a critical question on how baby stars develop. Using the ALMA radio telescope in Chile, the team found that in its infancy, the protostellar disk that surrounds a baby ...
