Their assumption was that multiple-planet systems would be the best places to look for more exoplanets. As a result, they found weak signals from a previously-missed eighth planet orbiting Kepler-90, a Sun-like star 2,545 light years from Earth in the constellation Draco and the first seven...
Peering into distant exoplanets: The Webb telescope carries specialized equipment called spectrometers that will revolutionize our understanding of these far-off worlds. The instruments can decipher what molecules (such as water, carbon dioxide, and methane) exist in the atmospheres of distant exoplanets...

Measuring these slight changes is another method of discovering planets. 4 When an exoplanet moves between its star and us, it causes a small drop in the star's brightness. By measuring this drop, NASA's Kepler space telescope has discovered many exoplanets....

Rogue planets have historically been difficult to detect. Astronomers discovered planets outside Earth's solar system in the 1990s. Those planets, called exoplanets, range from extremely hot balls of gas to rocky, dusty worlds. Many of them circle their own stars, the way Earth circles the sun...
