Hot Jupiters—giant gas planets that race around their host stars in extremely tight orbits—have become a little bit less mysterious thanks to a new study combining theoretical modeling with observations by the Hubble ...

An international team of astronomers has detected a new ultra-hot Jupiter extrasolar planet using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world is nearly two times larger than Jupiter and has ...
The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star. What did ...

An international team of astronomers has detected four new "hot Jupiter" exoplanets as part of the Next Generation Transit Survey (NGTS). The newly found alien worlds are at least 10% larger than Jupiter but less massive ...
For most of human history our understanding of how planets form and evolve was based on the eight (or nine) planets in our solar system. But over the last 25 years, the discovery of more than 4,000 exoplanets, or planets ...

Earth is doomed—but not for 5 billion years. Our planet will be roasted as our sun expands and becomes a red giant, but the exoplanet WASP-12b, located 600 light-years away in the constellation Auriga, has less than a thousandth ...

An international team of astronomers reports the discovery of a new "warm Jupiter" alien world transiting a main sequence late F-type star on an eccentric orbit. The newfound exoplanet, designated TOI-677 b, is about 20 percent ...
As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller planets should be more susceptible ...
