According to the space agency, the Hubble program has observed that the planet GJ 9827d during 11 transits were spaced out over a span of three years.
In a breakthrough, NASA astronomers have identified the smallest exoplanet using a Hubble Space Telescope where water vapour has been detected in the atmosphere. The planet GJ 9827d, at only approximately twice Earth's diameter, could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.
The newly discovered exoplanet is as hot as Venus, at 800 degrees Fahrenheit, according to NASA.
GJ 9827d was discovered by NASA's Kepler Space Telescope in 2017 and it completes an orbit around a red dwarf star every 6.2 days. The star, GJ 9827, lies 97 light years from Earth in the constellation Pisces, according to NASA.
