For example, telescopes are advancing fast with our technology and super scopes to look very far away are being made. Wide-First Infrared Survey Telescope, or WFIST is a high powered infrared ray telescope for looking at far away planets. There is another telescope called the K2 telescope. It can see oceans and skies of other planets, which is very helpful for finding planets with life on them. Light rays can be used to find planets, by using prisms to find dark spots in planets. It means light wavelengths find a change in color, which creates a black gap, indicating gases on a planet. It also finds smog for pollution for ET evidence. Finding evidence of ET is hard, but with our advancing technology, it will be
