Spiral galaxy captured in “unprecedented detail” by the James Webb Telescope

The stunning image shows the spiral arms of IC 5332.

New Delhi:

NASA’s James Webb Space Telescope has captured an image of a spiral galaxy in unprecedented detail. The galaxyLocated 29 million light-years away, it is slightly larger than the Milky Way.

Great movie I took Middle infrared device (MIRI)IC 5332 has the spiral arms of the galaxy. The galaxy was previously observed by the Hubble Space Telescope. Although the Hubble telescope also provided an impressive image of IC 5332, its “mirrors weren’t cold enough” to observe the mid-infrared regions of the electromagnetic spectrum.

That’s why the scientists used MIRI, the only JWST instrument sensitive to the mid-infrared region. MIRI is able to provide sharp infrared images and can operate at temperatures as cold as -266°C, which is 33°C lower than other observatories and only 7°C warmer than absolute zero.

MIRI helped capture details in the spiral galaxy that the Hubble Space Telescope mightn’t. IC 5332 is 66,000 light-years across, which makes it larger than our galaxy. In addition, the galaxy is strategically located as it is “almost directly facing Earth”. This allows astronomers to observe “symmetric scanning of its spiral arms”.

The image captured by JWST shows a series of interlocking structures that reflect the shape of the galaxy’s spiral arm. The Hubble Telescope image of the same galaxy shows dark areas separating the two arms.

According to the European Space Agency (ESA), this difference is due to the dusty regions of IC 5332, through which most visible and ultraviolet light fail to pass through and this results in dark gaps as shown in the Hubble image. But mid-infrared light can penetrate these areas, which is why the JWST image contains no dark gaps.

The two images are of different stars, with some stars appearing brighter in the ultraviolet, visible, and infrared, respectively.
