New observational data from the James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to understand how planets and planetary systems form.

To date, more than 5000 exoplanets have been confirmed around stars other than the Sun.

Many exoplanets are unlike any of the planets in the Solar System, making it difficult to guess their true natures.

One of the most common types of exoplanets falls in a size range between Earth and Neptune.

Astronomers have debated whether these planets are Earth-like rocky planets with thick hydrogen-rich atmospheres, or Neptune-like icy planets surrounded by water-rich atmospheres, called water worlds.

Previous studies have been ...

A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

The planet hunters spotted the Neptune-like planet as it crossed in front of its host star, temporarily dimming the star’s light in a way akin to a solar eclipse on Earth...

Astronomers have discovered a third planet in the Kepler-47 system, securing the system’s title as the most interesting of the binary-star worlds. Using data from NASA’s Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets.

With its three planets orbiting two suns, Kepler-47 is the only known multi-planet circumbinary system. Circumbinary planets are those that orbit two stars.

The planets in the Kepler-47 system were detected via the “transit method...
