"Unprecedented Discovery: Vast Water Reservoir Found in Distant Solar System"

Scientists using the ALMA observatory have discovered an immense volume of water vapour surrounding the young star HL Tauri, located 450 light-years away, which amounts to three times the volume of Earth's oceans. This finding could enhance the potential habitability of planets forming in this region, as it mirrors the conditions present during Earth's formation. The discovery sheds light on the role of water in planetary formation and its significance in the search for extraterrestrial life.

Hubble Telescope Discovers Water Vapor in Small Exoplanet's Atmosphere

NASA's Hubble Space Telescope has detected water vapour on exoplanet GJ9827d, located 97 light years away from Earth. The planet, approximately twice the size of Earth, has the potential for a water-rich atmosphere, although its high temperature of 800 degrees Fahrenheit makes it inhospitable. This discovery marks a significant step in identifying Earth-like worlds and understanding the prevalence and diversity of atmospheres on rocky planets.

NASA's Hubble Telescope Discovers Water Vapor on Small Exoplanet

NASA's Hubble Space Telescope has detected water vapour in the atmosphere of the exoplanet GJ 9827d, which is approximately twice the size of Earth and as hot as Venus. This discovery could indicate the presence of water-rich atmospheres on other planets in our galaxy. The planet, located 97 light years from Earth, completes an orbit around a red dwarf star every 6.2 days. Scientists are considering whether the planet could be a mini-Neptune with a hydrogen-rich envelope or a warmer version of Jupiter's moon Europa. NASA's focus now turns to understanding the total inventory of elements on the planet to compare with its host star and comprehend its formation.
