It is pretty easy to understand why medical discoveries stole all the spotlight in 2020. After all the entire world was anxiously waiting for one thing, and one thing only: a vaccine. However, other scientists kept working just as hard that year to advance knowledge in their own fields. In fact, astronomers made some big discoveries about the universe last year. Here are some of their best findings that might have gone unnoticed.
Weird Substance on the Moon
Detected in 2019 by the Yutu 2 rover, the substance was only described by Chinese researchers a year later. In the paper published in 2020, the scientists explain that this glassy dark green substance looks like a combination of broken mineral fragments cemented together. They also said that this material may have been formed due to an asteroid impact or volcanic eruption.
