The James Webb Telescope shows the hidden bones of this spiral galaxy

Hubble Y james webb they came together again for a new mission. Although a few months ago they provided an impressive view of a phantom galaxy, now each one is dedicated to a different task.

On this occasion, they have come together to take another photograph which was published on the website of the POT and also in the European Space Agency. In this you can see IC 5332, a galaxy smaller than the Milky Way with a spiral structure.

IC 5332 is a galaxy located about 29 million light-years from Earth and 66,000 light-years across, just over half the diameter of the Milky Way. Of course, thanks to the near-infrared cameras on board James Webb, ESA was able to observe this celestial formation even by photographing its “bones”.

Hubble, on the other hand, was responsible for capturing it using more traditional technology. So the image of IC 5332 in visible light and, to some extent, in ultraviolet light shows us the skin of the galaxy. So we have two images that complement each other and reveal more information than ever before.

What can be seen in the images of the galaxy IC 5332

As it cannot be otherwise, readers have already seen one of the images of IC 5332 captured by Hubble on the cover of this article. But, first it is important to talk about photography where you can see all the galaxy.

This was created thanks to the telescope’s special cameras, which record visible light (what can be seen with the eyes) and ultraviolet light. This reveals the way people are used to seeing images of galaxies.

Its spiral arms are fairly well defined, with bright star-filled regions and dark lanes, which are just patches of dust blocking the light of other stars within or behind them.

Fortunately, the James Webb Telescope allows you to see beyond even massive dust formations. Thanks to the MIRI (Mid-InfraRed Instrument) camera, this veil of dust in which the galaxy is embedded has been lifted, revealing its purest and most impressive internal structure. An interconnected network of orbits composed primarily of gas and stars.

Although both images are of the same celestial body, James Webb makes it easy to see the depths of galaxies. Therefore, scientists can find out much more about its formation, origin, and possible fate billions of years from now.

Thanks to the James Webb you can see details of galaxies like never before

Before the existence of the James Webb Space Telescope, the study of the universe was not as detailed as it is today. In fact, taking infrared images was, and still is, infinitely difficult. For example, this is impossible for ground-based telescopes because the atmosphere absorbs most of this light spectrum.

Hubble also made it almost impossible to obtain images at this frequency. This is because the mirrors of this technology they emit light in the mid-infrared, so any image in that spectrum would make the telescope much brighter than any other cosmic object, leaving the human eye unable to see what it really wants.

James Webb is equipped with mirrors and mid infrared cameras (MIRI) and near infrared (NIRCam, NIRSpec and NIRISS) that facilitate this type of images. Of course, making these catches is still not that easy.

To process such images without abysmal noise, the space telescope’s MIRI camera must be kept at a temperature of -266 degrees Celsius. Only in this cold environment can the detectors function properly and provide accurate readings.
