NASA's Hubble telescope photographed a galaxy 78 million light-years from Earth in incredible colors. About this the NASA.
The image shows the stellar spiral arms of NGC 6951. This galaxy is located in the constellation Cepheus.
It was discovered separately in 1878 and 1877 by the American and French astronomers Louis Sweet and Jerome Koja.
"NGC 6951 intrigues scientists with its stellar history. The galaxy had its highest rate of star formation about 800 million years ago, and then went quiet for 300 million years before stars began to be born again." - they write in NASA
Astronomers classify NGC 6951 as a type II Seyfert galaxy, which emits a large amount of infrared radiation and has a moving gaseous substance near its center.
Others attribute it to galaxies with low ionization of the nuclear emission region (LINER), which are similar to the previous one, but have a cooler core. It emits weakly ionized or neutral atoms, such as oxygen, nitrogen, and sulfur.
At the center of the galaxy is a supermassive black hole surrounded by a ring of stars, gas, and dust. It is assumed that the ring is between 1 and 1,5 billion years old.
In addition, some stars have exploded and gone supernova. Scientists continue to study the galaxy to better understand the environment of their formation.
