Thanks to the discovery of five twinkling galaxies in a rare alignment, astronomers have been able to calculate — for the first time — the properties and geometry of an invisible gas cloud in space.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
