Hubble Observes Atmospheres of TRAPPIST-1 Exoplanets in the Habitable Zone
Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system's habitable zone. Hubble reveals that at least the inner five planets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. This means the atmospheres may be more shallow and rich in heavier gases like carbon dioxide, methane, and oxygen.

Hubble Finds Water Vapor On Distant Exoplanet
Read moreWith data from the Hubble Space Telescope, water vapor has been detected in the atmosphere of a super-Earth within the habitable zone of its host star.K2-18b, which is eight times the mass of Earth, is the only planet orbiting a star outside the solar system (or “exoplanet”) within the habitable zone.For more information, visit https://nasa.gov/hubble.

Hubble Evidence of Possible Exomoon
Read moreAstronomers Find First Evidence of Possible Moon Outside Our Solar SystemNeptune-Sized Satellite Orbits A Giant Jupiter Around a Sunlike StarOur solar system has eight major planets, and nearly 200 moons. Though astronomers have to date found nearly 4,000 planets orbiting other stars, no moons have yet been found. That hasn’t been for any lack of looking, it’s just that moons are smaller than planets and therefore harder to detect.The Hubble and Kepler space telescopes found evidence for what could be a giant moon accompanying a gas-giant planet that orbits the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. The moon may be as big as Neptune and it orbits a planet several times more massive than Jupiter.Read the NASA press release at https://nasa.gov/press-release/astronomers-find-first-evidence-of-possible-moon-outside-our-solar-systemFind the science paper at advances.sciencemag.org/Visuals are also available at HubbleSite.org.Watch the scientists explain their research - https://youtu.be/eGjgD27Dtpc, https://youtu.be/vlcc2MdYaik ||
