Hubble Uses Earth as a Proxy for Identifying Oxygen on Potentially Habitable Planets Around Other Stars

Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth’s atmosphere. As a result, Hubble detected Earth’s own brand of sunscreen – ozone – in our atmosphere. The technique simulates how scientists will search for evidence of life on planets around other stars.
