The James Webb Space Telescope (JWST) has captured a truly spectacular view of the 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 a spiral galaxy, a 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 forming.
This dramatic image combines observations from two of the JWST’s powerful instruments: the mid-infrared instrument (MIRI) and the near-infrared instrument (NIRCam). MIRI detects mid-infrared light emitted by warm dust, revealing strands 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 stars. As 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 that material back into space. Massive stars explode into supernovas, scattering elements across hundreds of light-years, while smaller stars like our sun shed their outer layers as they expand into red giants.
By studying galaxies like NGC 5134 in infrared light, astronomers can trace this ongoing cycle of stellar birth, evolution and recycling, helping scientists understand how galaxies grow and change over billions of years.
