Most elliptical galaxies are usually found in galaxy clusters. However, a new picture of the galaxy NGC 474 captured by Hubble shows an interesting image. NGC 474 is in a relatively empty space rather than surrounded by a galaxy cluster. Next, the galaxy is surrounded by shells.
NASA says NGC 474 may be the result of absorbing smaller galaxies. Many believe that this must have happened billions of years ago. After all, no one is sure how this tidal shield formed around the Milky Way.
NASA’s Hubble Space Telescope has discovered some strange things. For starters, his nearly 30 years of observation have taught us a great deal about how the universe expanded. In addition, the telescope recently captured images of two galaxies locked in the dance. Now, however, a new photo gives us a glimpse of the Milky Way galaxy.
The galaxy in question is NGC 474 and is an elliptical galaxy. Hubble recently captured an image of the Milky Way galaxy and gave more information about its size. Scientists estimate that the galaxy is 2.5 times larger than our own galaxy. But, as I mentioned above, this size is not the only interesting feature.
Because the Milky Way galaxy has many layers of shields. Scientists are not sure what caused the conch. However, he believes that it may have been due to a galactic merger. Such mergers may result in the formation of different layered shells. NASA says that throwing pebbles into a lake creates waves throughout the water.
As I mentioned above, NGC 474 is located in a mostly empty space. In total, it is approximately 100 million light-years from Earth. It also counts approximately 250,000 light-years.
Because of its interesting features, scientists have studied the tides around the galaxy. Although many studies have been conducted on how the shell formed, the general consensus seems to be that NGC 474 absorbed another galaxy billions of years ago. This shell-enclosed galaxy makes it even more interesting, however, as it moves away from the sun.
Scientists believe that the galaxy is moving away at a speed of 2412 kilometers per second due to dark energy. So it can move farther away from the sun. Astronomers also discovered a supernova in the galaxy. When it was discovered in 2017, they named it SN 2017fgc.
