For a few evenings around 28 February, every planet in the solar system will be visible in the night sky, thanks to a rare great planetary alignment. Here's how to make sure you don't miss this ...

Astronomers have captured direct images of exoplanets in a star system 130 light years away, providing clues on gas giant ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...

The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and ...

Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and ...

The powerful James Webb Space Telescope is revealing the hidden complexities of exoplanets like never before. For the first time, Webb has captured “direct images” of carbon dioxide in an exoplanet ...

Once they are all in place, seven of the eight planets in our solar system will grace our sky. For much of the week, six of the planets may be visible, according to NASA. On Friday, however ...

A planet-size object that possibly once visited the solar system may have permanently changed our cosmic neighborhood by warping the orbits of the four outer planets, a new study suggests.

NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.
