The "Bone" Structure of a Galaxy

The latest photo of the James Webb Space Telescope has photographed the hidden gaseous  "bone" structure of a galaxy, which is definitely glorious. It is an enormous victory for astronomers.

The captured stars, the cosmic knot of gas, dust, and everything belong to the spiral galaxy IC 5332 also known as PGC 71775. The IC 5332 galaxy is located in the constellation sculptor more than 29 light years from earth. Light year means the distance the light can travel in a year. Nearly It is 9.46 trillion kilometers. So, this galaxy is located more than 274.34 trillion kilometers away from earth. The fastest speed by a spacecraft is 163km/s (586,800 km/h; 364,660 mph), which was achieved by the Parker Solar Probe at 21:25:24 UTC on 20 November 2021. With that speed, we should travel 21,347 years to approach this galaxy.

This is not the first time the telescope captured this galaxy. Hubble telescope also captures this 66,000 light-years long wide galaxy. This galaxy is roughly two-thirds the size of our Milky Way Galaxy. This time, the photograph is clear than the early one and can identify most hidden things in the galaxy. 

The Hubble Telescope can't see the infrared region of the electromagnetic spectrum. But, with the latest technology powered James Webb Telescope can see the infrared region. Therefore, the new image of this galaxy contains more details than the old image.
