New image from the James Webb Space Telescope shows thousands upon thousands of stars in a galaxy 17 million light years away – Yahoo Canada
The James Webb Space Telescope snapped a new image of a galaxy 17 million light-years away.
Thousands upon thousands of stars are visible, many of which are concentrated in the galaxy’s heart.
JWST is peering into the hearts of many galaxies to help scientists better understand star formation.
With the power of the James Webb Space Telescope, we can peer into the mysterious hearts of galaxies. And that’s exactly what you’re seeing here, in this new image from Webb of the galaxy NGC 5068.
NGC 5068 is located about 17 million light-years from Earth. For perspective, the Milky Way’s neighborhood of galaxies called the Local Group, is 5 million light-years away. So, this galaxy is beyond what we might consider close.
Each individual dot of white light you can see is a star, per Mashable. NASA said there are thousands upon thousands of stars in this image. And many of them are hanging out at the galaxy’s center, which you can see in the upper left as a bright bar of white light.
This region appears so bright because that’s where most of the stars are concentrated. That’s also where all the action is.
James Webb peers into the hearts of many galaxies to uncover their secrets
Most galaxies have an ultra-bright center due to warm dust that’s heated by massive bursts of star formation, according to the Harvard Smithsonian. And it’s this star formation that astronomers are interested in studying more with the help of JWST.
In fact, NGC 5068 is just one in a series of other galaxies Webb is observing for a project to help us better understand star formation. Webb has also taken images of the spiral galaxy IC 5332:
And the heart of galaxy M74, aka the “Phantom Galaxy”:
The James Webb Space Telescope has the advantage of seeing in the infrared.
Infrared wavelengths are too long for the human eye to detect. But they’re especially important for studying in space because they allow JWST to peer past obstructive visual light that would otherwise block our ability to see into the hearts of galaxies and their bustling environments of star formation.
“By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb,” NASA said.

Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions, such as unique spacecraft technologies.
In this first video, Nicolas recalls how he and his team had to think outside the box to find a solution for ESA to communicate with Ulysses. The spacecraft was flying around the north pole of the Sun, which is much farther in deep space than satellites had been launched up to that point.
The success of this solution motivated the decision to build ESA’s first deep-space communications antennas in New Norcia, in Australia, thus enabling many ESA scientific firsts in deep-space exploration.
The antennas would, some decades after, be critically important receivers for the messages sent by the very distant Rosetta probe, on its quest to find and land on the comet 67P/Churyumov–Gerasimenko, and other ESA science and exploration missions such as Mars Express, Venus Express and Cassini-Huygens.
With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.
In four episodes of this new series of ESA Masterclass, Nicolas takes us through major events in his career at ESA, covering cornerstone missions, first attempts, overcoming technical challenges, leading diverse teams and solving the unexpected problems that are part of any space endeavour.

Behind Galactic Bars: Webb Telescope Unlocks Secrets of Star Formation

” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>James Webb Space Telescope has captured a detailed image of the barred spiral galaxy NGC 5068. Part of a project to record star formation in nearby galaxies, this initiative provides significant insights into various astronomical fields. The telescope’s ability to see through gas and dust, typically hiding star formation processes, offers unique views into this crucial aspect of galactic evolution.
A delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image – a composite from two of Webb’s instruments. NASA Administrator Bill Nelson revealed the image on June 2 during an event with students at the Copernicus Science Centre in Warsaw, Poland.
NGC 5068 lies around 20 million light-years from Earth in the constellation Virgo. This image of the central, bright star-forming regions of the galaxy is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. Previous gems from this collection can be seen here (IC 5332) and here (M74). These observations are particularly valuable to astronomers for two reasons. The first is because star formation underpins so many fields in astronomy, from the physics of the tenuous <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>plasma that lies between stars to the evolution of entire galaxies. By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb.
The second reason is that Webb’s observations build on other studies using telescopes including the Hubble Space Telescope and ground-based observatories. Webb collected images of 19 nearby star-forming galaxies which astronomers could then combine with Hubble images of 10,000 star clusters, spectroscopic mapping of 20,000 star-forming emission nebulae from the <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>Very Large Telescope (VLT), and observations of 12,000 dark, dense molecular clouds identified by the Atacama Large Millimeter/submillimeter Array (ALMA). These observations span the electromagnetic spectrum and give astronomers an unprecedented opportunity to piece together the minutiae of star formation.
With its ability to peer through the gas and dust enshrouding newborn stars, Webb is particularly well-suited to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.
The James Webb Space Telescope stands as the apex of space science observatories worldwide. Tasked with demystifying enigmas within our own solar system, Webb will also extend its gaze beyond, seeking to observe distant worlds orbiting other stars. In addition to this, it aims to delve into the cryptic structures and the origins of our universe, thereby facilitating a deeper understanding of our position within the cosmic expanse. The Webb project is an international endeavor spearheaded by NASA, conducted in close partnership with the <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
