The James Webb Space Telescope (JWST) has succeeded in observing a whirlpool galaxy in space 27 million light-years away from Earth. / Photo = The James Webb Space Telescope (JWST) of the National Aeronautics and Space Administration (NASA) captured the M51 galaxy from space 27 million light-years from Earth (light years, about 9.46 trillion km, the distance that light travels in a year). M51 is also known as the Whirlpool Galaxy because of its spiral structure. The National Aeronautics and Space Administration (NASA) announced on the 30th that the JWST observed the inside of the M51 galaxy using mid-infrared equipment and a near-infrared camera. The dark red portion of the image is filamentary dust, while the orange and yellow portions are gas ionized by newly formed star clusters. It is a trace created by a strong internal interaction. M51 was first discovered by Charles Messier in 1773, and its spiral structure was confirmed by later scientists in 1845. M51 is made up of two galaxies (NGC 5194 and NGC 5195), and is sometimes referred to as the ‘rich man’ galaxy because it resembles a father and son.

It has 160 billion times the mass of the sun. M51 is gravitating towards NGC 5195. The Hubble Space Telescope captured M51 before the JWST, but it wasn’t quite this sharp. The most powerful technology of JWST is ‘Observation Wavelength’. The Hubble Space Telescope observed celestial bodies in the visible light region that we see with our eyes. However, JWST observes celestial bodies in the infrared region, which has a longer wavelength than visible light. In the same form as a thermal imaging camera, it is possible to shoot farther and darker places. In addition, it is located at the ‘Lagrange Point’, 1.5 million km away from the earth, so you can take clear pictures without distortion of light. For this reason, the JWST is expected to be able to observe even the first stars and galaxies born after the birth of the universe 13.8 billion years ago. In addition, it may be possible to secure data that can solve difficult problems in astronomy and space research, such as black holes and the rate of expansion of the universe. It will be able to unravel the history of the birth of the universe.
