Astronomers have discovered three new tiny moons orbiting the far-off planets Neptune and Uranus of the outer solar system.

The James Webb Space Telescope recently imaged two potential exoplanets orbiting around small, cold cores of dead stars called white dwarfs.

Astronomers have discovered a type of exoplanet called a "super-Earth" located in the habitable zone of its small star - and it's right in our cosmic backyard.

Hubble recently identified water vapor in the atmosphere of a small, hot exoplanet.

An Earth-sized orbits a star similar to our sun, but much, much closer - meaning it has surface temperatures of nearly 2,300 degrees Fahrenheit.

Planet WASP-121 b has a surface temperature of 5,000 degrees Fahrenheit, which researchers predict would lead to some wild weather phenomena.

Scientists using the James Webb Space Telescope recently announced they had made a rare detection of methane in an exoplanet atmosphere.

One of the least dense exoplanets known was recently investigated using James Webb, and the planet's weather seems is as strange as its puffiness.

Astronomers have created a video of an exoplanet called Beta Pictoris b, located 63 light-years away in the constellation Pictor, orbiting its star.

A Neptune-sized planet orbits close enough to its star that it is bombarded by dramatic flares which cook the planet with radiation and strip its atmosphere.
