This offers a new hope of directly observing individual stars at cosmological distances with JWST."Įarendel, also known under its proper name WHL0137-LS, is located in the constellation of Cetus, but don't expect to see it if you look up at the night sky - even gravitational lensing isn't that powerful.įollow Tereza Pultarova on Twitter at. The ambitious space observatory took off from the European Spaceport launch site near Kourou, in French Guiana, on 25 December 2021 on a European Space Agency (. "But in the past three years, three individual strongly lensed stars have been discovered. Until recently, we assumed that meant populations of stars within the first galaxies," astronomers from the Space Telescope Science Institute in Maryland, which operates Webb and Hubble, wrote in a recent paper discussing the technique. "JWST was designed to study the first stars. James Webb Space Telescope beats its own record with potential most distant galaxies Jupiter glows in new James Webb Space Telescope raw image A better understanding of its atmosphere could help astronomers characterize the planet and others like it.- Dazzling James Webb Space Telescope image prompts science scramble The Webb telescope’s observations also indicated that the exoplanet is a few hundred degrees warmer than Earth.

LHS 475 b is also closer to its star than any planet in our solar system, taking just two days to complete one full orbit, they found. The planet orbits a red dwarf star that is less than half the temperature of the sun, according to the scientists. The exoplanet is just 41 light-years away from Earth, in the constellation Octans. “A pure carbon dioxide atmosphere may be thin like the one on Mars, making it difficult to detect.” “We require very, very precise data to be able to distinguish a pure carbon dioxide atmosphere from no atmosphere at all,” Lustig-Yaeger said in a statement. The James Webb Space Telescope was launched on 25 December 2021 on an Ariane 5 rocket from Kourou, French Guiana, and arrived at the SunEarth L 2 Lagrange point in January 2022. The researchers said it’s possible that LHS 475 b has an atmosphere made up of pure carbon dioxide but added that this would be difficult to confirm even with the Webb telescope’s sophisticated instruments. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs.
“Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started.” The spacecraft launches no earlier than Christmas Day, 2021. “These first observational results from an Earth-size, rocky planet open the door to many future possibilities for studying rocky planet atmospheres with Webb,” Mark Clampin, director of the astrophysics division at NASA headquarters in Washington, D.C., said in a statement. Where is the Webb Telescope Live tracker The James Webb Space Telescope (JWST) is a large telescope that will be positioned in High Earth Orbit, about 1 million miles away. The finding demonstrates how the observatory could be used to search for potentially habitable planets in the cosmos and examine the chemical makeup of their atmospheres. The exoplanet confirmation marks an important milestone for the $10 billion Webb telescope, which launched into space in December 2021 and began science operations less than a year ago. The research was presented Wednesday at the 241st meeting of the American Astronomical Society in Seattle. The planet, called LHS 475 b, is a small and rocky world that is almost the same size as Earth, according to the research team, led by astronomers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.
