Object Messier 51, or Ngc 5194 the known Swirl Galaxy, is a spiral type, is in full collision interacting with another galaxy by the force of gravity attracted among each other.

It is located about 23 million light years from Earth 🌏 in the constellation Canes Venatici.

Image Description and Details :

The Whirlpool Galaxy is a classic spiral galaxy. Known as M51 and NGC 5194, this galaxy may have been the first galaxy for that identified spiral structure. It is located at a distance of 30 million light years from the Sun. Measuring 60,000 light-years across, it is one of the brightest and most beautiful galaxies in the sky. The Whirlpool Galaxy can be seen with good binoculars in the constellation Canes Venatici. The M51 galaxy belongs to the Sc type spiral galaxies and is the main member of a whole group of galaxies. Astronomers suggest that the appearance of the spiral structure of the galaxy M51 is mainly due to the gravitational influence of a small satellite galaxy NGC 5195.

Also in the picture, next to M51, you can see the galaxies IC4277, IC4278 plus many small galaxies in the background.

This image was originally intended to capture an extragalactic hydrogen cloud near M51. However even 22 hours of exposure through the Ha filter gave no hint of it.
