Earth-like exoplanet with volcanoes found by NASA’s TESS and Spitzer telescopes

[ad_1] Scientists using NASA's TESS (Transiting Exoplanet Survey Satellite) and Spitzer Space Telescope have made a remarkable discovery —an Earth sized exoplanet orbiting a star in a neighbouring galaxy. This finding provides the strongest evidence to date of active volcanoes existing beyond our solar system. The observations indicate that this rocky planet has a rugged surface and experiences frequent eruptions, resembling Jupiter's moon Io, which is the most volcanically active body in our solar system. While the volcanism on the exoplanet wasn't directly observed, scientists inferred its presence from the gravitational interaction with the larger of the two planets also orbiting the star. The gravitational pull of the larger planet may cause the newly identified exoplanet to flex a...

NASA Astronomy Picture of the Day 24 January 2023: Webb’s exoplanet discovery generated by AI

[ad_1] NASA’s Astronomy Picture of the Day is a stunning AI-generated picture of an exoplanet named LHS 475 b. Humans have been on the hunt for an Earth-like planet for years. The space race has led mankind to the Moon, Mars and even the outer solar system. Space agencies like NASA, ISRO, CNSA and ESA use their extensive resources to search for potential planets which could support life one day should the need to ever leave Earth arise. Although there are more planets in the Universe than you could ever imagine, only a handful of them have the potential to support life one day.To search for habitable planets which could potentially support life, NASA launched its Transiting Exoplanet Survey Satellite (TESS) on April 18, 2018. TESS is an all-sky survey mission that will discover thousa...

James Webb Telescope reveals exoplanet atmosphere as never seen before

[ad_1] New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet sulfur dioxide among other details. New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet sulfur dioxide among other details.The telescope's array of highly sensitive instruments was trained on the atmosphere of a "hot Saturn" -- a planet about as massive as Saturn orbiting a star some 700 light-years away -- known as WASP-39 b. While JWST and other space telescopes, including Hubble and Spitzer, previously have revealed isolated ingredients of this broiling planet's atmosphere, the new readings provide a full menu of atoms, molecules, and even signs of active chemistry and clouds. "The clarity of the signals from a number of different molecu...
