Hurt, K. Miller (Caltech/IPAC) It’s rare that 3 million years old would be considered young, but that’s the case for a recently discovered exoplanet. The study of planets outside our solar ...

A few decades ago, astronomers were just entering a new frontier of exoplanet discovery. Exoplanets are planets located outside our solar system. They orbit distant stars and represent mysterious ...

And that’s exactly what scientists have been doing for decades: searching for exoplanets, worlds orbiting faraway stars. They’ve had tremendous success: So far, NASA’s official count of ...

Data from the massive telescope also suggests the exoplanet, the name for a planet outside the solar system, may also have a surface covered in water and an atmosphere rich with hydrogen.

These exoplanets (planets orbiting a star other than our sun) orbit close to red dwarf stars that are smaller and cooler than the sun, and which make up over 75% of the 200 billion stars in the ...

One way to find water worlds beyond our solar system could be to look for minerals — or more specifically, to study minerals mixed with cool lava on exoplanet surfaces. This is because if water ...

Astronomers using the James Webb Space Telescope have detected possible signs of gases released by volcanic activity on a distant exoplanet. Today, we know of more than 5,000 exoplanets ...

When the first exoplanet was discovered in 1995, Sara Seager and Dave Charbonneau were graduate students at Harvard. Both were studying topics totally unrelated to planets orbiting distant stars.
