It is about 52 million light-years away in the direction of “Virgo”Spiral Galaxy “M61”This is a close – up of. The M61 is almost in front of the earth, gleaming in the centerGalactic bulgeAnd spread around itSwirl armHe is in a positional relationship that facilitates observation. In this image, which uses not only visible light to the human eye but also almost infrared and ultraviolet observation data,Young and warm blue starsThe vortex arm to whereIt looks like it’s redPainted.

That red partArea HIIIt is called by the ultraviolet rays emitted by young stars.Hydrogenated hydrogen gasShinesExhaust NebulaIt is a collection of gas and dustHigh density molecular cloudBA new star is bornBecause it’s also a place to doStar formation fieldAlso known as the M61, which has many HII regions, has intense star-forming activity.Starburst’s GalaxyIt is also classified as.

Also, although not captured in the image, it is also in the center of the M61, like many other galaxies.Super massive black holeIt is believed to exist. According to the European Space Agency (ESA), the M61The mass is 5 million times that of the sunIt is believed that there is a black hole. By the way, a massive black hole lurks in the center of the Milky Way galaxy“Sagittarius A * (Aster)”The mass of the M61 is about 4 million times that of the Sun, so the supermassive black hole of the M61 appears to be about one size larger than that of the Milky Way galaxy.

The picture at the beginning isHubble Space Telescope“Wide Field Camera 3 (WFC3)” and the Southern Observatory in Europe at the Paranel Observatory in Chile“Very Large Telescope (VLT)”It was created from the observation data of the “FORS2” observation device, and was released by ESA on April 5, 2021 as the “spiral image” of the Hubble Space Telescope this week.
