Webb Telescope Makes 'Baffling' Discovery

Scientists announce discovery of planet-sized objects unexplained by existing theories

(Newser) - The James Webb Space Telescope has shown us the most distant black holes known to exist , new exoplanets , possible planets in the making —and now, planet-sized objects previously unknown and unaccounted for by existing theories. Nearly 150 planet-like "Jupiter Mass Binary Objects," or JuMBOs—far too small...

Possible Sign of Life Detected 120 Light Years Away

Webb telescope makes intriguing find in atmosphere of planet K2-18b

(Newser) - A Hycean planet is a planet with a hydrogen-rich atmosphere and oceans of liquid water—and NASA says the James Webb Space Telescope may have spotted an intriguing one 120 light years away. Researchers say they have detected carbon-bearing molecules including methane and carbon dioxide in the atmosphere of K2-18b,...

NASA Releases Stunning Image of Star Birth

Agency is celebrating a year of images from the James Webb Space Telescope

(Newser) - The Webb Space Telescope is marking one year of cosmic photographs with one of its best yet: the dramatic close-up of dozens of stars at the moment of birth. NASA unveiled the latest snapshot Wednesday, revealing 50 baby stars in a cloud complex 390 light-years away. A light-year is nearly...

Webb Telescope Spots Farthest Black Hole Yet

Other discoveries closer to the Big Bang are under review

(Newser) - Astronomers have discovered the most distant black hole yet using the Webb Space Telescope, but the record isn't expected to last. The black hole is at the center of a galaxy dating to within a mere 570 million years of the Big Bang. That's 100 million years closer...

Webb Space Telescope Spots Its First Exoplanet

'With this telescope, rocky exoplanets are the new frontier'

(Newser) - The James Webb Space Telescope has made a hot new find: LHS 475 b, a rocky planet almost exactly the same size as Earth. The first exoplanet spotted by the telescope has 99% of our planet's diameter and is relatively close, 41 light years away in the Octans constellation,...

NASA Releases Stunning Images of 'Pillars of Creation'

James Webb Space Telescope captured star-forming region in vivid detail

(Newser) - Marvel's cosmic Silver Surfer would not seem out of place in the latest amazing images from the James Webb Space Telescope. The images show the Pillars of Creation, spires of interstellar gas and dust in an active star-forming region of the Eagle Nebula in the Serpens constellation, 6,500...

NASA Releases Staggering Photos of Neptune

Our most distant planet's rings are crisp

(Newser) - If you picture Neptune as a blue ring-less planet, new images released Wednesday from NASA's James Webb Space Telescope are about to set you straight. The images show what CNN refers to as the planet's "crisp, narrow rings." As Heidi Hammel of the Webb project says,...

'We’ve Never Seen Jupiter Like This'

Webb telescope captures stunning images

(Newser) - The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all. Scientists released the shots of the solar system's biggest planet Monday. The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter’s northern and southern lights, and...

Scientists Baffled by Neptune's Temperature Swings

Temps should be 'slowly growing warmer, not colder' amid southern summer

(Newser) - Neptune's southern hemisphere has spent the last 17 years in its summer season, yet global temperatures have plummeted. It's a head-scratching finding that leaves astronomers with more questions than answers. "Since we have been observing Neptune during its early southern summer, we would expect temperatures to be...

Evidence of Alien Life Might Emerge in a Cloud of Methane

The trick will be ruling out nonbiological explanations

(Newser) - Methane—a key ingredient in delightful things like swamp gas, flatulence, and fossil-fuel emissions —could also prove to be a key biosignature, i.e., evidence of extraterrestrial life. Thus, the gas is top-of-mind for scientists preparing to receive an influx of data from the James Webb Space Telescope. According...

$10B Space Telescope Is Beating Expectations

'We are excited about what this means for science'

(Newser) - "All of the sleepless nights I've had and the worries I've had, they're all behind us now," NASA associate administrator Thomas Zurbuchen said after tests confirmed that the James Webb Space Telescope is performing even better than expected. Engineers say the "fine phasing" process,...
