Astronomers have discovered 41 new alien planets in one sweep by analyzing how each world gravitationally yanks on its neighbors. The newly confirmed exoplanets were spotted by NASA's prolific Kepler ...

An international team, including researchers from Penn State, has unveiled the discovery of a potentially habitable "super-Earth" less than 20 light-years from our solar system, marking a significant ...

In a secluded corner of the Lynx constellation, just 18 light-years from our planet, astronomers have found a stunning jewel—a planet around a tiny red dwarf star that may have the right conditions to ...

A newly discovered “super-Earth” planet could allow us to finally see alien life, researchers say. The world – named GJ 251 c and lying less than 20 light years away – is thought to be a “super Earth” ...

Scientists using NASA’s James Webb Space Telescope have found a unique planet in another star system that’s shaped like a lemon. The lopsided Jupiter-style planet is so bizarre that it may blur the ...

For the first time in years, astronomers are seriously talking about adding a new member to the solar system’s planetary family. I’m not talking about reviving Pluto’s status, but about a potential ...

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 ...

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 ...

Alien solar systems that are home to so-called "hot Jupiters" — gas giants circling sizzlingly close to their stars — are unlikely homes for Earth-like planets, researchers say. Hot Jupiters get their ...

A recent conundrum about a star 1,500 light years away discovered by the Kepler Space Telescope has extraterrestrial enthusiasts crying "alien" as an explanation, but scientists studying the star are ...

Since the Kepler Space Telescope began its prowl for exoplanets in 2009, it has uncovered a strange pattern among these alien worlds: their orbits follow a consistent rhythm. If one planet in a system ...

The Penn State-led Habitable Zone Planet Finder (HPF) provides the highest precision measurements to date of infrared signals from nearby stars. Pictured: The HPF instrument during installation in its ...
