NASA's Hubble Telescope Catches Stunning Sight of Dying Galaxy --Sputnik International

The Hubble Space Telescope captured a galaxy called NGC 1947 , which is about 45.4 million light-years away from Earth. NGC 1947 was discovered in 1826 by astronomer James Dunlop. Unlike other galaxies, NGC 1947 is classified as a 'lenticular galaxy ' in that it has few components such as gas and dust and no spiral arms can be seen.
Below is a photo of NGC 1947 that emits a faint light.
Galaxyes that have not created new stars for billions of years are considered 'dead.' NGC 1947 used to have a spiral arm like other galaxies and used gas etc. to create new stars, but now it runs out of star material and only faintly emits light in the center. It will take a long time for NGC 1947 to die completely, but it is expected that it will continue to decline without creating new stars. For this reason, the photograph of NGC 1947 attracted attention as a 'photograph of a dying galaxy'.
On the other hand, the Milky Way galaxy, to which the solar system belongs, died once 7 billion years ago and is thought to have regenerated 2 billion years later. At the time of writing the article, the Milky Way galaxy is thought to be far from the end, although star formation is relatively slow.
The high resolution image of NGC 1947 can be downloaded from the following.
