When it comes to hunting for the explosive deaths of massive stars in the early universe, the James Webb Space Telescope (JWST) is quite the cosmic detective. This celestial Sherlock Holmes has found evidence of 80 new early supernovas in a patch of sky as wide as a grain of rice held at arm’s length. […]

James Webb Space Telescope spots asteroid collision in neighboring star system
The James Webb Space Telescope (JWST) has observed evidence pointing to asteroids colliding in a neighboring star system. Resultant dust kicked up by the collision has a mass equal to around 100,000 times that of the asteroid that killed the dinosaurs. The asteroids were seen smashing together in Beta Pictoris, a star system located about […]
James Webb and Chandra telescopes spot a ‘lighthouse’ pointed at Earth
What it is: The Crab Nebula (also called M1), a supernova remnant Where it is: 6,500 light-years away in the constellation Taurus When it was shared: June 3, 2024 Why it’s so special: This new composite image combines data from both the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory to reveal more […]
Rocky, carbon-rich exoplanets more likely around tiny stars, James Webb Space Telescope reveals
Using the James Webb Space Telescope, astronomers have discovered the richest “menu” of hydrocarbons ever seen in a planet-forming disk. This observation, which involved the protoplanetary disk around a tiny star, also revealed the first detection of ethane outside the solar system. The discovery was made when the Mid-Infrared instrument (MIRI) on the James Webb […]
James Webb telescope discovers the 2 earliest galaxies in the known universe — and 1 is shockingly big
The James Webb Space Telescope (JWST) has done it again. According to new research, astronomers using the powerful infrared telescope have revealed what appears to be the two earliest, most distant galaxies in the known universe, dating to just 300 million years after the Big Bang. The ancient galaxy duo break the records set by […]
Earliest-known galaxy, spotted by Webb telescope, is a beacon to cosmic dawn
By Will Dunham WASHINGTON (Reuters) – NASA’s James Webb Space Telescope has spotted the earliest-known galaxy, one that is surprisingly bright and big considering it formed during the universe’s infancy – at only 2% its current age. Webb, which by peering across vast cosmic distances is looking way back in time, observed the galaxy as […]
James Webb Space Telescope finds a dusty skeleton in this starburst galaxy’s closet
The dwarf galaxy NGC 4449 is the star of the show in the James Webb Space Telescope‘s latest cosmic portrait. Located 12.5 million light-years away in the constellation of Canes Venatici, the Hunting Dogs, NGC 4449 has much in common with our very own Large Magellanic Cloud (LMC), the satellite galaxy orbiting the Milky Way. […]
James Webb Space Telescope spots the 2 earliest galaxies ever seen (image)
The James Webb Space Telescope (JWST) has discovered not one but two of the earliest and most distant galaxies ever seen, continuing to break the records it previously set. The furthest galaxy, JADES-GS-z14-0, is seen as it was around 300 million years after the Big Bang, existing at least 100 million years earlier than the […]
Webb telescope finds most distant galaxy ever observed, again
The James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday. Since coming online in 2022, the Webb telescope has ushered in a new era of scientific breakthroughs, […]
James Webb telescope sees ‘birth’ of 3 of the universe’s earliest galaxies in world-1st observations
For the first time ever, astronomers using the James Webb Space Telescope (JWST) may have detected some of the earliest galaxies in the known universe in the midst of being born. In a new study, published Thursday (May 23) in the journal Science, the researchers report the detection of what appears to be three infant […]
James Webb Space Telescope spots 3 of our universe’s earliest galaxies
Astronomers using the James Webb Space Telescope have found what they say are three of our universe’s earliest galaxies, spotted actively forming when the cosmos was just 400 million to 600 million years old. In the JWST’s images, this galactic trio resembles fuzzy red smudges feeding on nearby helium and hydrogen.Over millions of years, it […]
The James Webb Space Telescope may have solved a puffy planet mystery. Here’s how
A surprisingly low reservoir of methane may explain how a planet around a nearby star grew weirdly puffy, according to new observations from the James Webb Space Telescope (JWST(. The finding shows that planetary atmospheres can inflate to remarkable amounts without employing esoteric theories of planet formation, astronomers say. “The Webb data tells us that […]
