A newly discovered planet in a binary star system located 3,000 light-years from Earth
Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size.
Scientists working with data from NASA’s Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn’s smog-enshrouded moon Titan
In deep space, floating between the stars, lies an abundance of atoms -- carbon, oxygen, hydrogen -- that over millions of years will grow into new stars and new planets.
Astronomers have for the first time managed to detect the rotation of an extrasolar planet, by analysing the way its atmosphere filters light.
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable
Titan, Europa, Io and Phobos are just a few members of our solar system's pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun?
A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars.
NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."
Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water exist throughout the universe.
Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat.
After nearly a decade of development, construction and testing, the world’s most advanced instrument for directly imaging and analyzing planets around other stars is pointing skyward
Washington: Astronomers, who took precise measurements of the closest pair of failed stars to the Sun, have found that the system harbours a third, planetary-mass object.
A long-standing puzzle in the study of exoplanets is the formation of hot Jupiters, gas giant planets that snuggly orbit their host star.
