Astronomers using NASA’s Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.

In a system with two known planets, astronomers spotted something new: a small object transiting across the Sun-sized star. This turned out to be another planet: extra hot and Earth-sized.

Experts will discuss new research from NASA missions at the 243rd meeting of the American Astronomical Society (AAS), on topics ranging from planets outside our solar system to fleeting, high-energy explosions in the universe. The meeting will take place Jan. 7-11 at the New Orleans Ernest N. Morial Convention Center in New Orleans. In press […]

By combining several years of observations from NASA’s Hubble Space Telescope along with conducting computer modelling, astronomers have found evidence for massive cyclones and other dynamic weather activity swirling on a hot, Jupiter-sized planet 880 light-years away. The planet, called WASP-121 b, is not habitable.

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable […]
