Behold! New Images From Webb Telescope Show Rivers of Stars and Dust
https://www.inverse.com/science/jwst-sees-the-ianes-of-dust-gas-in-spiral-galaxiesThe James Webb Space Telescope (JWST) continues to mesmerize with its latest views of the Universe.
Scientists caught unprecedented sights of star-making material when they directed a JWST instrument to look at a handful of nearby galaxies. Their data revealed billowing strands of dust too faint to see with other telescopes, as well as clusters of stars near galactic hearts and ‘spurs’ where the dusty cocoons gestate new stars. These pretty visuals provide astronomers with the first steps to charting how stellar nurseries may influence the much grander shapes of their home galaxies.
Astronomers with the PHANGS survey (short for Physics at High Angular resolution in Nearby Galaxies) looked at a handful of face-on galaxies. With this imagery, astronomers are peering into stellar formation in galaxies located millions of light-years away.
They include this view of NGC 1365, a barred spiral galaxy located roughly 60 million light-years away. The bar acts like a road for the star-making material, which can make its way to the center of the galaxy and boost ongoing star formation at its core. JWST’s Mid-Infrared Instrument (MIRI) collected the data for this image.
To see the flow of dusty trails, astronomers needed next-generation instruments tuned in to infrared, a segment of the electromagnetic spectrum where the dust’s subtle heat could be detected.
“JWST allows us to precisely pinpoint the youngest stars still within their birth clouds in nearby galaxies. This capability enables us to look inside the gas and dust in gas-rich galaxy [centers] to study where and how inflowing gas is converted into stars, like in NGC 1365, and compare those results to the Milky Way,” Eva Schinnerer, PHANGS collaborator, states in a description of the images published on Thursday by the Max Planck Institute for Astronomy (MPIA). (Schinnerer is a research group leader at MPIA.)

JWST captured this view of NGC 1365, a barred spiral galaxy located roughly 60 million light-years away in the constellation of Fornax (the Furnace).

JWST captured this view of NGC 628, a grand-design spiral galaxy located 32 million light-years from Earth.
