Researchers take the ultimate Earth selfie
What we learned:
- Researchers used the Hubble Space Telescope to view Earth as if it were an exoplanet, or a world orbiting a star many lightyears away.
- The group recorded the properties of sunlight that had filtered through the planet's atmosphere, then bounced off the surface of the moon during a total lunar eclipse.
- The researchers were able to detect the signature of the ozone in Earth's atmosphere鈥攁 molecule that is a potential "biosignature" for the presence of life.听
Even outdoors鈥攚hy face coverings are important
What we learned:鈥�
- Face coverings work. Basically, face coverings reduce how many viruses an infected person puts into the air, and they also reduce how many viruses a susceptible person will inhale. They reduce both.
- You don't want to be talking to someone in close proximity without a face covering. The approach that is closest to a silver bullet of prevention is being outdoors, distanced and with face coverings.
- Make sure your face covering fits well.
