M51 is a grand-design spiral galaxy about 25 million light-years away from Earth and boasts very well-developed arms.
, the dark red regions trace the filamentary warm dust permeating the medium of the galaxy. These rosy regions show the reprocessed light from complex molecules forming on dust grains. The orange and yellow portions show areas of ionized gas created by recently formed star clusters.
Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like M51. CREDIT: ESA/Webb, NASA & CSA, A. Adamo and the FEAST JWST team.Atacama Large Millimetre Array in the Chilean desert and the Hubble Telescope gave astronomers a glimpse of star formation. These observations occurred at either the onset, when the dense gas and dust clouds where stars will form, or after the stars have been destroyed with their energy their natal gas and dust clouds. JWST is opening up a new observational window to the earlier stages of star formation and stellar light.
“Scientists are seeing star clusters emerging from their natal cloud in galaxies beyond our local group for the first time. They will also be able to measure how long it takes for these stars to pollute with newly formed metals and to clean out the gas ,” wrote the ESA.More observations and study of these processes is expected to lead to a better understanding of how the whole

JWST is the Perfect Machine to Resolve the Hubble TensionOver the last decade, various measurements have disagreed over the rate that the Universe is expanding. Astronomers use Cepheid variables as standard candles to measure relatively nearby galaxies and then use them to calibrate more distant candles like Type 1a supernovae. The most accurate measurements have been done with the Hubble Space Telescope, but a new survey of 330 Cepheid variables has been done with JWST, narrowing down the error bars even more and building a perfect distance ladder to Type 1a supernovae.
