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

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 ...

Just two decades after astronomers discovered the first exoplanet, NASA has confirmed the existence of 6,000 alien worlds. The total will rise even quicker as next-generation telescopes take flight.

A trio of newly discovered exoplanets is defying the expectation that binary systems are hostile to planet formation, according to an international team of researchers.

Three decades ago, in 1995, humankind discovered the first planet beyond the borders of our solar system. It's called 51 Pegasi b, and it spins around its main-sequence star (meaning not unlike our ...

After marking the 30th anniversary of the discovery of the first exoplanet around a sun-like star, we now look forward to what the next 30 years might offer. With the number of exoplanets having ...

Lava planets, which have one face perpetually turned toward their star and heated to temperatures capable of melting rock, offer a unique natural laboratory for exploring the interactions between ...

If you think you've met the wildest exoplanet yet, you haven't learned about TOI-4507 b. This strange world, which sits about 578 light-years from the solar system, breaks almost every known rule for ...
