Using ESA's Herschel telescope a team of Chinese researchers has performed analysis of the interstellar medium in the early-type galaxy NGC 3665. The study offers insights into physical properties of the matter between its ...
Sirius is not a single star at all, but a binary system of two stars. Polaris, the north star, is actually a system of three stars. And Castor, in the constellation of Gemini, actually consists of a whopping six stars. Current ...
