Student: Exoplanets are planets that orbit around a star other than our Sun, right? They are not in our solar system. Professor: Right. They have different... what are called "host stars". And the study of exoplanets has been getting more and more exciting. Hundreds of them have been ...

NASA's TESS satellite has discovered a "Second Earth." What's even more exciting is there may be an entire universe full of these possibly habitable exoplanets.
“We have imaged a few exoplanets, but they are splotches of light orbiting a star. We have no technical ability to actually see the surface of exoplanets yet,” Byrne said. “This paper is one of a small but growing number of studies taking a geological or geophysical perspective to try ...
Also, since TRAPPIST-1 is a cool star, liquid water could exist on any of the seven planets.Scientists have been focusing on the three exoplanets in the habitable (可居住的) zone which are most beneficial to life. Planet E even gets the same amount of starlight and is the same size ...
If you had asked anyone just 30 years ago, the answer would have been "we don’t know". But since then we have discovered already more than 5,000 planets orbiting stars other than our sun (so-called exoplanets). And since often we find multiple of them orbiting the same star, we can...
at the core of a planet in a way that we can’t do in our own solar system. There are still big open questions about the nature of Jupiter’s core, for example, so strange and unusual exoplanets like this give us a window into planet formation that we have no other way to explore...
They have different, what're called host stars. The study of exoplanets has been getting more and more exciting; hundreds of them have been discovered so far. This is quite remarkable in view of the fact that the discovery of the first exoplanets was confirmed only in the mid-1990s. Now ...
A rocky planet that could have liquid water at its surface orbits a star 490 light-years away. More resources on exoplanets: Exoplanets: Worlds Beyond Our Solar System Alien Planet Quiz: Are You an Exoplanet Expert? How Habitable Zones for Alien Planets and Stars Work: Infographic ...
