But, when you see a photo of a spiral galaxy, a good guess is that the arms trail the direction of rotation. Right of the Whirlpool Galaxy is NGC5195. It’s fairly bright and I’ve seen it in binoculars in a reasonably dark sky. The galaxy was discovered in 1773 by Charles Messier. The only way to be sure of the rotational direction is to measure the motions of stars or gas in a galaxy, which requires more than just an image. M51 is the galaxy in which spiral structure was first seen, by Lord Rosse in 1845 using a 72-inch telescope known as the Leviathan of Parsonstown. Galaxies that have recently merged with or been disturbed by another galaxy can sometimes rotate with their spiral arms leading. But there have been some recent observations that suggest not all galaxies rotate with their arms trailing. In most cases, spiral galaxies spin with their arms trailing the direction of rotation. This finding was recently confirmed by a group of citizen scientists who looked at thousands of images of spiral galaxies and determined that half looked to be rotating clockwise and the other half counterclockwise. By extension, galaxies shouldn’t have a preferred direction of spin from our perspective. This stems from the idea that we live in an “isotropic” universe, which means that the universe looks roughly the same in every direction. But if viewed from the other side, it looks to be spinning counterclockwise.Īstronomers have long thought that about half of all galaxies should be rotating in one direction, and half in the other. When you look at a spinning wheel from one side, it looks like it’s spinning clockwise. As an analogy, consider a spinning bicycle wheel. The direction a galaxy rotates depends on your perspective. The Whirlpool galaxy's wonderful face-on view and proximity to Earth allow astrophysicists to study the structure and star-forming procedures of a classic spiral galaxy.About half of all spiral galaxies appear to be rotating clockwise and the other half counterclockwise. It has an apparent magnitude of 8.4 and is best seen with a powerful telescope in May. M51 is found in the cluster Canes Venatici, 31 million light-years from Earth.

The red in Hubble's stunning image of M51 signifies infrared light as well as hydrogen within massive star-forming regions. The image is currently causing a stir on the internet, with over 8,000 likes and over a thousand retweets. The Whirlpool Galaxy, true to its name, has spiral galaxy characteristics such as magnificently looping arms, pink star-forming regions, and beautiful blue strands of star clusters. Hubble's Advanced Camera for Surveys caught this soporific spiral galaxy in visible light. The awe-inspiring M51 galaxy is also known as the 'Whirlpool' galaxy. NASA captioned the image "Round and round we go." on its official Twitter account. Svalhalla, the Greek Viking May 22, 2022 This is supernatural! So real! Reminds me War of the Worlds veins near the end of the film The US space agency has released dazzling images taken by Hubble Telescope One of their most latest shares is an image that appears to be a majestic spiral staircase enveloping through space.

The galaxy is literally a feast for the eyes you can't take your eyes away from it. When you think you've seen it all, NASA always surprises you.
