One of the properties that make a planet suitable for life is the presence of a weather system. Exoplanets are too far away to directly observe this, but astronomers can search for substances in the atmosphere that make a ...

Astronomers from the University of Chicago and elsewhere report the detection of an outflowing helium from the atmosphere of a nearby mini-Neptune exoplanet known as TOI-2134 b. The finding was detailed in a research paper ...
A new study by McGill University astronomers has found that the temperature on the nightsides of different hot Jupiters is surprisingly uniform, suggesting the dark side of these massive gaseous planets have clouds made of ...

(Phys.org)—A "hot Jupiter" exoplanet transiting a rapidly rotating star has been discovered jointly by WASP and KELT survey, a new study reveals. The newly found alien world, designated WASP-167b/KELT-13b, is several times ...
For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star. The stricken world appears destined to spiral closer and closer to its maturing star until collision ...

Exoplanets, planets that orbit stars other than the sun, are found at distances very far from Earth. For example, the closest exoplanet to us, Proxima Centauri b, is 4.2 light years away, or 265,000 times the distance between ...

Since astronomers discovered the first planet orbiting a star other than the Sun, we have found many worlds that are very unlike the ones in our own Solar System. A large number of these "exoplanets" are large, gaseous planets ...
