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...
While for now this approach is mostly limited to signatures from brown dwarf and stellar companions, future phases of the Gaia mission will push these methods to lower masses and allow for the discovery of new giant exoplanets. Clémence Fontanive adds: “On top of having so many new discoverie...
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 ...
By measuring this drop, NASA’S Kepler space telescope has discovered many exoplanets.(当一颗系外行星在它的恒星和我们之间移动时,它会导致恒星亮度的小幅度下降。通过测量这种下降,美国宇航局的开普勒太空望远镜发现了许多系外行星)”可知,上文提到了一种发现行星的方法,后文则说美国宇航局通过这种办法发现了...
