NASA\'s most powerful James Webb Space Telescope has made an amazing discovery. Scientists have found two galaxies 8 and 10 billion years old. The second galaxy is 19 billion light years away. The color of both is red. It is a spiral galaxy like our Milky Way Galaxy.
What is a spiral galaxy?
Spiral galaxies are the most common type of galaxy in the universe. It is always active and stars are being formed in it. The color of such a galaxy appears blue because new stars shine in ultraviolet light. However, some galaxies are also red. Their stars are old and they are surrounded by a huge amount of gas.
James Webb\'s telescope took a clear picture
Researchers say that both these galaxies named RS13 and RS14 have been discovered earlier also. Earlier, Hubble Space Telescope and Spitzer Space Telescope had achieved this success. However, due to their limited resolution range and sensitivity, it was impossible to study the size and properties of the galaxy. Now the James Webb telescope has solved this problem.
Very rare red spiral galaxy
Scientists told that it is very rare to see a red-colored spiral galaxy. This is because they are only 2% of spiral galaxies. Surprisingly, the galaxies RS13 and RS14 are captured in the same picture. Scientists were studying SMACS J0723.3-7327 Galaxy.
The farthest away is the RS14 Galaxy
According to researchers, the RS14 Galaxy started forming more than 10 billion years ago. Today it is 19 billion light-years away from us due to the expansion of the universe. According to research, the discovery of such galaxies tells us about the secrets hidden in the universe and its expansion over the centuries. This research has been published in The Astrophysical Journal Letters.
