Cattail: A giant arm still hidden in the galaxy? Chinese scientists saw mysterious figure
The universe is so vast that solving each puzzle is a huge challenge. The recent discovery in our Milky Way galaxy is a prime example of this. To this day, large quantities of gas are still hidden from scientists and today when they are discovered, everyone is amazed. Even questions have arisen as to whether it is the arm of the Galaxy itself.
The thing, called Cattail, is believed to be the largest gas filament in existence. The study, published in the Astrophysical Journal Letters, states that it appears to be the longest and largest cable on our Galaxy. Scientists from Nanjing University of China conducted the study. The question is, how did it happen? Astronomer Chong Lee with the help of the Aperture Spherical Radio Telescope (500 meters) wanted to find a neutral atomic hydrogen (HI) that is often found in the rings of galaxies.
According to the Science Alert report, the number and shape of galaxy arms can be determined by the difference in hydrogen light. In August 2019, researchers detected the release of HI radio with the help of FAST and found a larger status in the data. When calculating the speed of the stir, scientists were amazed. Its speed was 71,750 light years away from the center of the Galaxy. This area is just outside the Galaxy. No arm has been found yet.
The size of this large cord is believed to be 3,590 light-years long and 675 light-years wide. Interestingly, its size was found to be high while the data was integrated with the HI4PI All-Sky HI Survey. Its length is probably 16,300 light years. The discovery of this Cattail has stand many questions. Most of the gas is located near the center of the Phylamint Galaxy and is associated with the spiral arm. If this figure is filamentous, then how it was formed and how it stayed away from the spiral arms, these questions have been raised.
