The tiny spacecraft will study energetic behavior the galaxy’s most common stars.

Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that denote a distant world. Now NASA has announced the number ...

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is potentially the first Earth-like one that also orbits a sun-like star.

How many planets outside our solar system, known as exoplanets, exist throughout the Milky Way Galaxy? While that might never be determined, NASA recently announced the total number of confirmed exoplanets has reached a historic 6,000, with an additional ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits within a "habitable zone," according to NASA. Astronomers ...

Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one orbiting Earth could potentially form. Using data from NASA’s James Webb Space Telescope, a team of researchers were able to ...

NASA has confirmed 6,000 exoplanets, marking a major milestone in humanity’s quest to understand other worlds. From gas giants hugging their stars to planets covered in lava or clouds of gemstones, the diversity of discoveries is staggering. With ...

Forbes contributors publish independent expert analyses and insights. I cover aerospace, astronomy & hosted The Cosmic Controversy Podcast. Sep 18, 2025, 09:28pm EDT Sep 18, 2025, 09:29pm EDT Four planets locked in a perfect rhythm around a nearby star (HR ...

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of humanity's most fundamental questions: Are we alone in the universe?

(Nanowerk News) The official number of exoplanets — planets outside our solar system — tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no single planet is considered ...

NASA researchers explore a hybrid observatory using a space-based starshade and ground telescopes to improve direct imaging and detect hidden Earth-like exoplanets.
