NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere
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. “This would be the first time that we can directly show through […]
NASA Hubble Observes How an Exoplanet’s Atmosphere Changes (Video)
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. But this result is an important early step in studying […]
