Using 20 years of data from the Hubble Space Telescope astronomers have discovered that turbulent stars could be corrupting observations of some exoplanets.
By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new giant "planet," plus a new brown dwarf.
WASP-121b is like nothing in the solar system, raining liquid metal and being puffy like a marshmallow. The origins of these "toasted marshmallow" planets could be more complicated than thought.
Located less than 20 light years away, HD 20794d could potentially be one of the most Earth-like planets found so far, despite its extreme climatic variability.
"The planet has complex weather patterns just like Earth and other planets of our own system."
Hot Jupiters may not be the lonely giants scientists once thought they were.
When two giant planets collide, an even bigger world may be born.
Once thought to be 8 billion years old, the star HD 110067 — famous for its six synchronized exoplanets — may be only 2.5 billion years old, new research suggests.
An ancient exoplanet dated at 12.7 billion years old could have formed over a long period in a giant disk of gas, according to new JWST observations.
Investigating a young exoplanet called PDS 70b in its cocoon of natal gas and dust has shown that planets don't always resemble the environments they form in.
