The Hubble Space Telescope, known for its ability to look into a deeper universe, has witnessed the outer part of our galaxy. The spacecraft has created a beautiful image of a galaxy that is almost 2.5 times larger than the Milky Way. The Hubble Space Telescope has captured the central part of NGC 474, a galaxy 100 million light-years from Earth that is vast, almost 250,000 light-years wide, and 2.5 times larger than in the Milky Way.
According to NASA, NGC 474 consists of a series of complex layers of envelopes that surround a spherical core. The origin of these shells is unknown, but astronomers believe they are the result of a giant galaxy sucking up small galaxies, for example. It is said to be like a small stone that wrinkles in a pond when it falls into the water. Similar shells are made of waves created by absorbable galaxies.
Most elliptical galaxies consist of clusters of galaxies and elliptical shells and are usually located in space. However, nearly 10% of elliptical galaxies have envelope structures, which may indicate cannibalization of their neighbors. Data from an advanced Hubble camera was used to create an image of this galaxy, where it represents visible blue light and red light that is close to infrared light. NASA also uses data from the Hubble Wide Field and Planetary Camera 2 and Wide Field Camera 3. Hubble is an engaging word for scientists outside of Earth who look at the vastness of space and discover planets, stars, and celestial phenomena. Three decades after its launch and several repair missions later, the spacecraft remains healthy and continues to observe space while waiting for the James Webb telescope.
With the James Webb Space Telescope ready to go, Hubble will remain a critical asset for astronomers around the world. Launched on April 25, 1990, Hubble has been providing us with stunning scientific discoveries and imaginative images of the universe for more than three decades.
