“We’ll see a couple of examples from the lifecycle of stars, starting from the birth of stars, where Webb can reveal new young stars emerging from a cloud of gas and dust, to the death of stars, like a dying star, seeding the galaxy with new elements and new dust that may one day become part of new planetary systems.” “We'll also see an example of how galaxies interact and grow and how these cataclysmic collisions between galaxies drive the process of star formation process that happens in the universe to this day,” said Pontoppidan. “Each of them will reveal a different aspects of the infrared Universe in unprecedented detail and sensitivity.” “We will have a package that will consist of a number of full color images,” said Klaus Pontoppidan, Webb project scientist, Space Telescope Science Institute. SMACS 0723: an extremely distant and intrinsically faint cluster of ancient galaxies imaged using gravitational lensing. Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is a group of galaxies located in the constellation Pegasus. Southern Ring Nebula: The Southern Ring planetary nebula – an expanding cloud of gas surrounding a dying star - is 2,000 light-years away from Earth. It has about half the mass of Jupiter, and its discovery was announced in 2014. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. WASP-96b (spectrum): a giant planet outside our solar system, composed mainly of gas. Yesterday NASA confirmed these five objects will feature in Webb’s first images:Ĭarina Nebula: one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. No-that was its alignment images in late April 2022, which showed how sharp Webb’s optics were, but didn’t contain much in the way of exciting targets. NASA/STScI Didn’t we already see Webb’s first images? This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast. At this stage of Webb’s mirror alignment, known as “fine phasing,” each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. This galaxy more stars forming in its outskirts than in its centre.Ħ) The cosmic rose: As per details, the galaxy lie at varying distances encompassing redshifts from 2.5 to 3.9.While the purpose of this image was to focus on the bright star at the center for alignment. It is surprisingly bright at just 430 million years after the Big Bang.Ĥ) The big clumpy one: At a redshift of 8, this galaxy lies around 300 million years later than the record holder.ĥ) The inside-out one: It was 700 million years after the Big Bang. As per Brant Robertson, an astronomer at the University of California, It is pumping out new stars at a rate comparable to the Milky Way today.Ģ) The glowing dog bone: This dog-bone-shaped object is at a redshift of 11.3, though its distance still needs to be confirmed.ģ) GN-z11: It was first spotted with Hubble and at a redshift of 10.6. Here are 6 distant galaxies captured by JWST that are wowing astronomers:ġ) The record holder (JADES-GS-z13-0): JWST discovered the galaxy, which lies at a redshift of 13.2 and is physically small, just a few hundred light-years across. But JADES identified a whopping 717 galaxies that are probably in this range. It is through redshift - the higher the redshift, the more distant the object, and the astronomers measure distance in space.īefore JSWT launch in 2021, only a few dozen galaxies had been spotted at redshifts greater than 8.
