If you want to see the “bones” of a galaxy, look no further. For a complete list of images and their descriptions, see the official Webb Gallery, where you’ll also find analysis graphs that explain the properties of distant objects in space, such as Exoplanet 96B’s atmospheric composition. The images here include all of the publicly-released Webb photos and descriptions, plus some edits that amateurs have created from original Webb data. In fact, CEERS-93316 is an astounding 35 billion light-years away. One of the galaxies Webb saw emerged from a fledgling universe, only 235 million years after the Big Bang, making it the oldest galaxy we’ve ever laid eyes on. Let’s nerd out over it together-join Pop Mech Pro. Webb fills in the gaps with infrared instruments, whose data can be combined with previous visible and ultraviolet spectrum imaging, providing the first complete images of planets and galaxies. On July 12, the James Webb Space Telescope’s near-infrared and mid-infrared instruments issued their first clear glimpses of thousands of galaxies in a deep-field view that took advantage of gravitational lensing, when the powerful gravitational field of a huge group of galaxies bends the light rays from more distant galaxies, pulling them into our view. The new findings are published in an article, ‘The Sparkler: Evolved high-redshift globular cluster candidates captured by JWST’, published in The Astrophysical Journal Letters.What’s the oldest galaxy humanity has ever seen? Our vision now extends to astonishingly cosmic distances. But the increased sensitivity of Nasa’s new telescope meant they could be looked at closely enough to understand what they are, and how old they might be. Until now, those the objects around the Sparkler galaxy had been difficult to actually see. We hope the knowledge that globular clusters can be observed at from such great distances with JWST will spur further science and searches for similar objects.” “Since we could observe the sparkles across a range of wavelengths, we could model them and better understand their physical properties, like how old they are and how many stars they contain. Iyer, Dunlap Fellow at the Dunlap Institute for Astronomy & Astrophysics at the University of Toronto and co-lead author of the study, in a statement. “Looking at the first images from JWST and discovering old globular clusters around distant galaxies was an incredible moment, one that wasn’t possible with previous Hubble Space Telescope imaging,” says Kartheik G. ![]() The clusters are so old that they were born almost as soon as possible as it was actually form stars. Scientists looked at 12 of those objects and found that five of them were globular clusters – and some of the oldest ever spotted. Scientists thought that those sparkles could be recently-formed clusters that are creating stars, or older globular clusters, which are ancient collections of stars that formed in the very beginning of a galaxy. That galaxy is 9 billion light years away but can be seen in part because of the “sparkles” that surround it, appearing as orange dots. ![]() And they were lurking, hidden in that early image that delighted the world.įrom that image, researchers looked at the “Sparkler” galaxy. Now it has been used to begin a hunt that could end with the discovery of the oldest stars ever seen. Just in recent days, it has tracked Nasa’s similarly groundbreaking DART mission from afar and given new insights into Neptune. The findings are just the latest breakthrough from the James Webb Space Telescope, which scientists have suggested could change how we do astronomy fundamentally because of the sheer amount of data it is able to give us. “This discovery in Webb’s First Deep Field is already providing a detailed look at the earliest phase of star formation, confirming the incredible power of JWST.”
