(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, ...
(Phys.org)—Before there were lasers, there were masers—devices that operate in the microwave regime and other wavelengths that are longer than those of visible light. But while the first masers were built back in the ...
(Phys.org) —This new Hubble image is centered on NGC 5793, a spiral galaxy over 150 million light-years away in the constellation of Libra. This galaxy has two particularly striking features: a beautiful dust lane and an ...
