(Phys.org)—Using the Australia Telescope Compact Array (ATCA), a team of astronomers has detected methanol emission toward a nearby galaxy known as NGC 4945. The finding, reported Aug. 18 in a paper published on arXiv.org, ...
Our Milky Way galaxy produces on average a few new stars every year across the entire system. Massive young stars emit large amounts of ultraviolet radiation which heats the local dust, and so the star formation process results ...
