Using the Atacama Large Millimeter/submillimeter Array (ALMA), Italian astronomers have investigated an active galaxy known as Markarian 509. Results of the study, presented in a paper published July 14 on arXiv.org, deliver ...
Using the ARO 12-m telescope, astronomers have investigated a young starless core known as Lynds 1521E (or L1521E). The study resulted in the detection of complex organic molecules in this object. The finding is detailed ...
In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios ...
