Webb reveals dynamic panorama of star formation, including smallest known brown dwarfs
This starry view of the nearby star-forming region IC 348 is one of the largest images released to date from NASA's James Webb Space Telescope. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered brown dwarfs just twice the mass of Jupiter, bringing the study of these curious objects into a new mass range and revealing new insights about the star-formation process.
Researchers of the James Webb Space Telescope (JWST) identified new candidates for brown dwarfs in the star formation region IC 348, located about 1,000 light-years from Earth. The study, published in The Astrophysical Journal Letters, brings new evidence about the formation and characteristics of these celestial objects. Analysis of the formation of brown dwarfs The brown dwarfs are astronomical objects that lie between stars and gaseous planet…
James Webb Discovers Brown Dwarfs of Just Two Masses of Jupiter in Their Greatest Panorama of IC 348
The James Webb detects two-mass brown dwarfs of Jupiter in the IC 348 region and challenges the models of stellar formation. The entry James Webb discovers brown dwarfs of just two masses of Jupiter in its greatest panorama of IC 348 aparece primero en Merca2.
The James Webb Space Telescope has confirmed 348 brown dwarfs with estimated masses of only about two Jupiter masses in the young star cluster IC. NIRCam images and NIRSpec spectra identified nine new substellar members, including the most massive brown dwarfs with spectral classification so far. The findings move the observation boundary deep into the planet's mass range, with the masses based on unsafe development models. Greenbelt (U.S.A.). […
Stars Embedded within Nebula IC 348 in Perseus | James Webb Space Telescope
Stars Embedded within Nebula IC 348 in Perseus | James Webb Space TelescopeThis image showcases a portion of the larger IC 348 field to highlight two stars embedded within a cloud of gas and dust. The central star, despite being brighter and appearing larger than its companion to the lower-right, is in fact more deeply wrapped in the clouds of gas and dust. These clouds block more of the shorter-wavelength infrared light that the star emits, lea…
