Stunning star nursery is latest JWST image to amaze astronomers

July 13, 2023838 Views

The stunning picture of the star-forming region closest to Earth is the latest to be released by the James Webb Space Telescope (JWST). NASA unveiled the image to mark one year since the landmark telescope released its first photograph. The first anniversary image from NASA’s James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. It shows an area in the Rho Ophiuchi cloud complex, 120 parsecs (390 light years) away, that contains roughly 50 young stars — most of which have masses similar to, or less than, that of the Sun. It is the closest star-forming region to Earth. The vertical and horizontal red streaks on the upper and right-hand side of the image are molecular hydrogen illuminated by jets of material produce...

Compact galaxy’s discovery shows Webb telescope’s ‘amazing’ power

The detection of a highly compact galaxy that formed relatively soon after the Big Bang and displayed an impressive rate of star formation is the latest example of how the James Webb Space Telescope is reshaping our understanding of the early universe. Scientists said the galaxy, dating to 13.3 billion years ago, has a diameter of approximately 100 light-years - about 1,000 times smaller than the Milky Way - but forms new stars at a rate very similar to that of our much-larger present-day galaxy. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). It existed about 510 million years after the Big Bang event marking the universe's origin. The universe at the time was less than 4% of its current age. Using first-of-their-kind observations from...

The messy death of a star

A global forensic team of astronomers led by Australia’s Macquarie University reconstructs using stunning James Webb Space Telescope images Around 2500 years ago, a star ejected most of its gas, forming the beautiful Southern Ring Nebula, NGC 3132, chosen as one of the first five image packages from the James Webb Space Telescope (JWST). A team of nearly 70 astronomers from 66 organisations across Europe, North, South and Central America, and Asia have used the JWST images to piece together the messy death of this star. “It was nearly three times the size of our Sun, but much younger, about 500 million years old. It created shrouds of gas that have expanded out from the ejection site, and left a remnant dense white dwarf star, with about half the mass of the Sun, but approximat...

Webb Space Telescope spots early galaxies hidden from Hubble

NASA’s Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million years after the cosmic-creating Big Bang. Astronomers said Thursday that if the results are verified, this newly discovered throng of stars would beat the most distant galaxy identified by the Hubble Space Telescope, a record-holder that formed 400 million years after the universe began. “Everything we see is new. Webb is showing us that there's a very rich universe beyond what we imagined,” said Tommaso Treu of the University of California at Los Angeles, principal investigator on one of the Webb programs. “Once again the universe has surprised us. These early galaxies are very unusual in many ways.” Launched last December as a...

Webb’s NIRCam Instrument Shows the Beginning of Protostar Evolution NASA’s James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb's Near-Infrared Camera (NIRCam). The protostar within the dark cloud L1527, shown in this image from NASA’s James Webb Space Telescope, is embedded within a cloud of material feeding its growth. Ejections from the star have cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. The upper central region displays bubble-like shapes due to stellar “burps,” or sporadic ejections...

NASA’s Webb takes star-filled portrait of Pillars of Creation

October 25, 2022849 Views

Near-infrared light uncovers vast populations of forming stars, many still encased in dust NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light. This image of the Pillars of Creation, captured by Webb’s Near-Infrared Camera (NIRCam), shows compass arrows, scale bar, and color key for reference. It lies within the Eagle Nebula, which is also known as Messier 16 (M16). The north and east compass arrows show the orientation of the image on the s...

The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all. Scientists released the shots Monday of the solar system’s biggest planet. The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter’s northern and southern lights, and swirling polar haze. Jupiter’s Great Red Spot, a storm big enough to swallow Earth, stands out brightly alongside countless smaller storms. One wide-field picture is particularly dramatic, showing the faint rings around the planet, as well as two tiny moons against a glittering background of galaxies. This image provided by NASA shows a false color composite image of Jupiter obtained by the James Webb Space Telescope on July 27, 2022. The planet’s rings and some of its small...

A sparkling landscape of baby stars. A foamy blue and orange view of a dying star. Five galaxies in a cosmic dance. The splendors of the universe glowed in a new batch of images released Tuesday from NASA’s powerful new telescope. The unveiling from the James Webb Space Telescope began Monday at the White House with a sneak peek of the first shot — a jumble of distant galaxies that went deeper into the cosmos than humanity has ever seen.
