Researchers are studying eccentric warm Jupiters, giant exoplanets that follow odd, elongated orbits unlike anything in our solar system.

Ultra-hot Jupiters — named as such because of their physical similarities to the planet Jupiter — are exoplanets that orbit stars other than the sun with temperatures so high that the molecules in ...

In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely hospitable to life. And as technology advances, astronomers only expect to ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger ...

"The complexity of the exo-Neptunian landscape provides offers a unique window onto the processes involved in the formation and evolution of planetary systems." Astronomers have launched a new program ...

Worlds upon worlds await us in the cosmos and we’re finding more all the time. Before 1992, we weren’t even completely certain planets existed outside of our solar system. Now, astronomers are finding ...

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...
