This week's science news kicked off with a staggering first look at images taken by the newly operational Vera C. Rubin Observatory in Chile. Boasting the world's largest digital camera, Rubin's first photo of the night sky included 10 million galaxies in and around the Virgo cluster, many of which have never been seen before.

The observatory, which will become fully operational by the end of 2025, promises to gather more data than all other existing optical observatories combined in its first year alone, representatives said in a statement. It's hoped that this data will enable scientists to discover the locations of previously unseen asteroids and gain new insights into the properties of dark matter and dark energy, among other things.
