Astronomers get the best look yet at the surface of an exoplanet
WASHINGTON, DC, USA – Astronomers have gotten their clearest look yet at the surface of an exoplanet — a planet beyond our solar system — thanks to NASA’s James Webb Space Telescope. Webb gathered data on a rocky exoplanet with a diameter about 30% larger than Earth that indicates it is a desolate and airless world whose surface may resemble that of Mercury, our solar system’s innermost planet. Its lack of a discernible atmosphere and its extrem…
Astronomers have obtained the clearest perspective on the surface of an exoplanet – a planet located beyond our solar system – thanks to NASA's James Webb Space Telescope, transmits Reuters. Webb has collected data on a rocky exoplanet with a diameter of about 30% greater than Earth's, indicating that it is...
A team of American scientists used the James Webb space telescope to indirectly measure the light emitted by the planet Kua的kua nearly 50 light years away from Earth. A technical feat that allows us to begin to understand the geology of this star, which could look like Mercury.
James Webb Telescope captures clearest-ever view of exoplanet’s surface
Astronomers using NASA’s James Webb Space Telescope have obtained the clearest view yet of the surface of a rocky exoplanet, revealing a scorched, atmosphere-free world that scientists say resembles a giant version of Mercury. The planet, known as LHS 3844 b and nicknamed “Kua’kua,” appears to be a barren, uninhabitable world with extreme temperature swings and no detectable atmosphere, according to a study published this week in Nature Astronom…
The James Webb telescope made a first. For the very first time, astronomers analyzed directly the composition of the surface of a rocky exoplanet, LHS 3844 b. The verdict? An infernal, dark and sterile world, without any atmosphere, whose surface would be covered with basalt, a volcanic rock found on the Moon or Mercury.
