NASA's Hubble Space Telescope will study Venus's atmosphere during an upcoming opportunity where Venus is passing in front of the Sun. Hubble cannot look at the Sun directly, so astronomers are planning to point the telescope at the Moon, using it as a mirror. The next time Venus will pass in front of the Sun will be in the year 2117.
