Purple galactic whirlpool spotted in space
(ORDO NEWS) — The image shows the galaxy NGC 628 in the mid-infrared. Spiral arms, star formation nodes, supernova explosions and dust clouds stand out in this cosmic dance of chaos.
According to scientist Gabriel Brammer (Gabriel Brammer) from the University of Copenhagen in Denmark, a distant galaxy resembles ours – some even call it a twin of the Milky Way.
The unusual purple hue is due to the unique chemical composition of NGC 628’s dust clouds. They are made up of molecules called polycyclic aromatic hydrocarbons.
Recall that the latest James Webb telescope, launched into space on December 25, 2021, is equipped with many scientific instruments for studying space objects, including:
- Near-Infrared Camera (Near-Infrared Camera);
- Device for working in the middle range of infrared radiation (English Mid-Infrared Instrument, MIRI);
- Near-Infrared Spectrograph (NIRSpec);
- Fine Guidance Sensor (FGS), as well as an imaging device in the near infrared range and a slitless spectrograph (Near InfraRed Imager and Slitless Spectrograph, NIRISS).
