Space and astronomy news
In the Fall of 1989, the Galileo spacecraft was launched into space, bound for Jupiter and its family of moons. Given the great distance to the king of planets, Galileo had to take a roundabout tour through the inner solar system, making a flyby of Venus in 1990 and Earth in 1990 and 1992 just to gain enough speed to reach Jupiter. During the flybys of Earth Galileo took several images of our planet, which astronomers have used to discover life on Earth.

That was somewhat expected since the Galileo cameras were optimized for Jupiter, which is much more distant from the Sun and therefore much dimmer. However, the team was able to detect an oxygen absorption line, verifying that our planet has an oxygen-rich atmosphere.
