If this new image from Webbs mid-infrared instrument (MIRI) looks dark and moody, that's because things look different in mid-infrared light than in visible, ultraviolet, or near-infrared light the wavelengths you may be more used to seeing from Hubble, Webb and other space telescopes.

These are the "bones of galaxy IC 5332, usually hidden by dust. In mid-infrared light, Webb is able to peer through that dust and see the patterns of gas spread throughout the galaxy.

Webb only has one instrument thats able to see in mid-infrared, making MIRI cool in more ways than one. MIRIs cryocooler, a special refrigerator, helps keep it just a few degrees shy of absolute zero, the lowest possible temperature!

[Image description: Image of galaxy IC 5332 as taken by the Webb telescopes MIRI instrument, resembling gray cobwebs in the shape of a spiral. These cobwebs are patterns of gas spread throughout the galaxy. The core of the galaxy glows a dark blue. Stars, seen as tiny blue dots, are scattered throughout the image. There are also sparser, larger red dots spread out among the spiral arms. The background of the image is dark.]

Objekt navn : Webb Inspects the Heart of the Phantom Galaxy
Bildetekst : This image from the NASA/ESA/CSA James Webb Space Telescope shows the heart of M74, otherwise known as the Phantom Galaxy. Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the centre of this image. A lack of gas in the nuclear region also provides an unobscured view of the nuclear star cluster at the galaxy's centre. M74 is a particular class of spiral galaxy known as a ‘grand design spiral’, meaning that its spiral arms are prominent and well-defined, unlike the patchy and ragged structure seen in some spiral galaxies. The Phantom Galaxy is around 32 million light-years away from Earth in the constellation Pisces, and lies almost face-on to Earth. This, coupled with its well-defined spiral arms, makes it a favourite target for astronomers studying the origin and structure of galactic spirals. Webb gazed into M74 with its Mid-InfraRed Instrument (MIRI) in order to learn more about the earliest phases of star formation in the local Universe. These observations are part of a larger effort to chart 19 nearby star-forming galaxies in the infrared by the international PHANGS collaboration. Those galaxies have already been observed using the NASA/ESA Hubble Space Telescope and ground-based observatories. The addition of crystal-clear Webb observations at longer wavelengths will allow astronomers to pinpoint star-forming regions in the galaxies, accurately measure the masses and ages of star clusters, and gain insights into the nature of the small grains of dust drifting in interstellar space.Hubble observations of M74 have revealed particularly bright areas of star formation known as HII regions. Hubble’s sharp vision at ultraviolet and visible wavelengths complements Webb’s unparalleled sensitivity at infrared wavelengths, as do observations from ground-based radio telescopes such as the Atacama Large Millimeter/submillimeter Array, ALMA.
