James Webb Telescope

The James Webb Space Telescope (JWST) is a space telescope currently conducting infrared astronomy. As the largest optical telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars, the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.

James Webb Space Telescope Images Challenge Theories of How Universe Evolved

“AUSTIN, Texas — The James Webb Space Telescope (JWST) appears to be finding multiple galaxies that grew too massive too soon after the Big Bang, if the standard model of cosmology is to be believed. In a study published in Nature …

NASA’s Webb Telescope Captures Rarely Seen Prelude to Supernova

“A massive star on the cusp of death ejected huge volumes of hot gas into space. Webb’s Mid-Infrared Instrument revealed the structure of the material now surrounding the star. The rare sight of a Wolf-Rayet star – among the most …

NASA’s Webb Reveals Intricate Networks of Gas, Dust in Nearby Galaxies

“Peering through obscuring clouds of dust, the MIRI instrument has revealed networks of giant cavities and blown-out bubbles in the gaseous arms of distant galaxies. Researchers using NASA’s James Webb Space Telescope are getting their first look at star …

Webb Detects Extremely Small Main Belt Asteroid

“NASA’s newest astrophysics observatory wasn’t designed to look for small objects in our solar system, but scientists using its Mid-Infrared Instrument may have done just that. An asteroid roughly the size of Rome’s Colosseum – between 300 to …

James Webb reveals the atmospheric secrets of an exoplanet

“Thanks to the James Webb Space Telescope, an international team including UNIGE scientists is building a complete picture of the atmosphere of the planet WASP-39b. The James Webb Space Telescope (JWST) and its unparalleled images of our Universe offer …

James Webb Space Telescope Uncovers Massive Galaxy Cluster Surrounding a Powerful Red Quasar

“UMD astronomer Sylvain Veilleux served as co-principal investigator of this latest glimpse into the early universe Astronomers peering into the early Universe have made a surprising new discovery thanks to the world’s most powerful space telescope. The James Webb …

Star Duo Forms ‘Fingerprint’ in Space, NASA’s Webb Finds

“A new image shows at least 17 dust rings created by a rare type of star and its companion locked in a celestial dance. A new image from NASA’s James Webb Space Telescope reveals a remarkable cosmic sight: at …

New Webb Image Captures Clearest View of Neptune’s Rings in Decades

“NASA’s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet’s rings in more than 30 years, but its …

A Cosmic Tarantula, Caught by NASA’s Webb

“The cycle of star formation is on display in this nearby nebula. Webb’s MIRI instrument captures protostars nestled deep in clouds of gas and dust, still gathering mass. Once upon a space-time, a cosmic creation story unfolded: thousands of …

Carbon dioxide in an exoplanet atmosphere

“The James-Webb-Telescope provides insights into the composition and formation of planets outside our solar system. Using the James Webb Space Telescope, an international collaboration of astronomers with Laura Kreidberg of the Max Planck Institute for Astronomy has captured infrared light …
