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 ...

Using the Gran Telescopio Canarias (GTC), astronomers have performed optical imaging observations of an isolated ultra-thin galaxy known as UGC 11859. Results of the observational campaign, published July 12 in The Astrophysical ...
Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers ...
