The James Webb Space Telescope (JWST) has captured a truly spectacular view of spiral galaxy NGC 5134, revealing glowing dust clouds, newborn stars and the ongoing cycle of stellar life and death.
What is it?
NGC 5134 is one spiral galaxya type of galaxy characterized by a bright central core surrounded by sweeping arms filled with stars, gas and dust. These arms act as cosmic nurseries where new stars are constantly being formed.
This dramatic image combines observations from two of JWST’s powerful instruments: the Mid-Infrared Instrument (MIRI) and the Near-Infrared Instrument (NIRCam). MIRI detects mid-infrared light emitted by hot dust, revealing filaments and clumps of gas scattered throughout the galaxy. NIRCam captures shorter-wavelength infrared light that highlights the stars and star clusters embedded deep within the spiral arms.
Why is it amazing?
The glowing dust clouds visible throughout the galaxy are the raw material for new ones stars. Seam gravity pulls this gas together, new stars ignite – gradually using up all the galaxy’s star-forming fuel. When stars die, they return some of their material back into space. Massive stars explode in supernovaescatters elements across hundreds of light-years, while smaller stars like our Sun shed the outer layers as they expand to red giants.
By studying galaxies like NGC 5134 in infrared light, astronomers can track this ongoing cycle of star birth, evolution and recycling, helping scientists understand how galaxies grow and change over billions of years.
