Bullseye! Galaxy with nine rings may also reveal dark matter secrets

A team of international researchers recently discovered a galaxy with nine rings. They called it a “serendipitous discovery” because previous ringed galaxies have only displayed two or three rings at best. Using the Hubble space telescope, the team confirmed the presence of eight rings, while data from the W.M. Keck Observatory in Hawaii confirmed the … Read more

Scientists find green way to recycle toxic perovskite solar cells

Using solar energy may be better for the environment than burning through fossil fuels, but the process still isn’t exactly perfect. Making silicon-based solar panels is energetically expensive and we still don’t know what to do with the silicon once the panels are done being used. There is a cheaper way to make solar panels, … Read more
