Intrigue in the universe.. not thanks to James Webb but instead our old friend the Hubble!!
The planet, named GJ 9827d, is about twice Earth’s diameter, and it’s the smallest exoplanet found to have water vapor in its atmosphere, according to a new study.
“Water on a planet this small is a landmark discovery,” said study coauthor Laura Kreidberg, managing director of the atmospheric physics of exoplanets department at the Max Planck Institute for Astronomy in Heidelberg, Germany, in a statement. “It pushes closer than ever to characterizing truly Earth-like worlds.”
Yet the planet reaches temperatures of 800 degrees Fahrenheit (427 degrees Celsius), making it a steamy, inhospitable world that’s as hot as Venus.
Astronomers using the Hubble Space Telescope have detected water molecules in the atmosphere of a small, blazing-hot exoplanet 97 light-years from Earth.
