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....
“This result was only possible because we believed that, when combining space and ground-based facilities to directly image exoplanets, the whole is greater than the sum of its parts. We hope that this will be the start of a new era of synergy between different instruments and detection meth...
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...
Astronomers have discovered a whole new class of alien planet: a vast population of Jupiter-mass worlds that float through space without any discernible host star, a new study finds. While some of these exoplanets could potentially be orbiting a star from very far away, the majority of them ...
In the study, researchers first trained the neural network they developed to identify exoplanets using 15,000 signals from Kepler data that have already been examined previously. It turned out the neural network correctly identified true planets and false positives 96 percent of the time. ...
