(Phys.org)—A team of researchers working in France has detected the presence of aldehydes in ice samples in their lab which were created to simulate material found in interstellar molecular clouds. In their paper published ...
(Phys.org) —Astronomers working to estimate the rate of star formation inside murky distant galaxies, those shrouded in dust clouds that make it very difficult to study them, have published data from a brand new instrument, ...
