A small galaxy bursts with star formation in a dazzling new image from the James Webb Space Telescope. The galaxy, called I Zwicky 18 (I Zw 18), is located roughly 59 million light-years from Earth. It is classified as a dwarf irregular galaxy, meaning it’s much smaller and less structured than our Milky Way galaxy. […]
NASA’s James Webb Space Telescope (JWST) is known for capturing our universe with unprecedented precision and sensitivity. Its images aren’t only scientifically useful but also beautiful. From the blue and gold of the Southern Ring Nebula to the pink, orange and purple of Cassiopeia A, JWST images render the universe in brilliant color. The images […]
The James Webb Space Telescope (JWST) is set to begin investigating the spectacular light shows of solar system giants Uranus and Saturn. Two separate teams of astronomers at the University of Leicester will use the $10-billion space telescope to study auroras over the gas giant Saturn and the frigid ice giant Uranus. The aim will […]
What was little more than a speck of light for the Hubble Space Telescope has been revealed as one of the oldest galaxies ever discovered — and the finding owes itself to none other than Hubble’s younger sibling: The James Webb Space Telescope. The James Webb Space Telescope international “Glass” Collaboration made detailed observations of […]
Using the James Webb Space Telescope, astronomers have identified several of the icy building blocks of life in the gas and dust swirling around two infant stars, or “protostars.” The molecules spotted range from relatively simple molecules like methane to complex compounds like acetic acid and ethanol. Complex organic molecules (COMs) in solid, icy form had […]
The James Webb Space Telescope (JWST) has double checked the work of its older sibling, the Hubble Space Telescope. Hubble’s measurements of the expansion rate of the universe are exemplary, the trailblazing observatory found, further ratcheting up the so-called “Hubble tension.” Putting it simply, measurements of the expansion rate of the universe, defined by a […]
Two spectacular new images from the James Webb Space Telescope (JWST) reveal the stunning and intricate details of a star-birthing region in the Triangulum Galaxy. The James Webb Space Telescope imaged the star-forming region NGC 604, located some 2.7 million light years from Earth, using its Near-Infrared Camera (NIRCam), and its Mid-Infrared Instrument (MIRI). The Triangulum […]
A stellar nursery filled with hundreds of blistering-hot and massive newborn stars is captured in two new images by the James Webb Space Telescope, which showcase the uniquely dense region of outer space in stunning detail. The images were produced by the Webb telescope’s Near-Infrared Camera and Mid-Infrared Instrument, or NIRCam and MIRI, giving complementary […]
In examining a pair of icy asteroids at the edge of the solar system, the James Webb Space Telescope is helping scientists understand the evolution of an ice giant: Neptune. These findings could also help reveal how ancient Earth grew saturated with water, the ingredient that ultimately led to the emergence of life. The binary […]
NASA’s James Webb Space Telescope, the agency’s successor to the famous Hubble telescope, launched on Dec. 25, 2021 on a mission to study the earliest stars and peer back farther into the universe’s past than ever before. Webb is currently at its observing spot, Lagrange point 2 (L2), nearly 1 million miles (1.6 million km). […]
Usually, the most thrilling black-hole news surrounds the biggest, baddest and most violent voids we can imagine. I’m talking about the supermassive black holes boasting billions of times the mass of the sun; the ones called quasars that eat up surrounding matter and spew out the excess so aggressively they create light patterns that outshine […]
By Will Dunham WASHINGTON (Reuters) – The James Webb Space Telescope since becoming operational in 2022 has uncovered numerous surprises about what things were like in the universe’s early stages. We now can add one more – observations of a galaxy that was already “dead” when the universe was only 5% of its current age. […]
