The high-resolution Hubble Space Telescope shows spiral arms that contain millions of stars from the galaxy NGC 2775.
Galaxy NGC 2775 is 67 million light-years from Earth in the constellation Cancer, according to Sci-News on June 29. This galaxy was discovered by English astronomer William Herschel on December 19, 1783. It is classified as a clustered spiral galaxy . The shape of this type of galaxy is in contrast to the perfect spiral galaxy, the spiral arms are clearly separated and easily identifiable.

In the photo, the spiral arms of NGC 2775 contain millions of glowing blue young stars, interspersed with dark dust bands.
An unusual feature of galaxy NGC 2775 is the bulge. Most spiral galaxies have a bulge in the center, where many stars cluster. In spiral arms, the stars are more sparsely distributed. Spiral arms also tend to spread across a plane while bulges protrude above and below the galaxy.
With NGC 2775, the bulge is not only larger than normal but also relatively hollow, almost no newly formed stars. The bulge contains a small amount of gas. According to scientists, this may be evidence that in the past, this place has occurred many supernova explosions.
The Hubble Space Telescope is operated by NASA and the European Space Agency (ESA). Hubble launched into space in 1990 and continues to operate.
