Rare Galaxy, Messier 90, Is Getting Closer to The Milky Way

There are millions of galaxies in the Universe, but due to the Universe expansion, only a few of those are moving closer to the Milky Way. According to a new study, Messier 90 is getting closer to the Milky Way, making it one of the rare galaxies that do that. NASA’s Hubble Space Telescope made the observations on the Messier 90 galaxy using its Wide Field and Planetary Camera 2.

Messier 90 is a fantastic spiral galaxy, spotted in 1781 by the renowned astronomer Charles Messier. Located at about 60 million light years away from the Milky Way, Messier 90 is part of the approximately 1,200 galaxies of the so-called Virgo Cluster, and it is the brightest one in that cluster.

However, Messier 90’s trajectory in the Universe is what interests the scientists. According to the latest observations, this rare galaxy is getting closer to the Milky Way, and that makes it quite unique.

Messier 90 galaxy is moving closer to the Milky Way

Because of the Universe expansion, all the galaxies near the Milky Way are moving away for our home galaxy. But Messier 90 is not doing that since it’s getting closer to the Milky Way. The scientists reached that conclusion after observing the light trajectory of this beautiful spiral galaxy.

Blueshift is a phenomenon in which the light wavelengths that come from the galaxy as it gets closer to us. So, the light increases in frequency and look blueish. “Astronomers think that this blueshift is likely caused by the cluster’s colossal mass accelerating its members to high velocities on bizarre and peculiar orbits, sending them whirling around on odd paths that take them both towards and away from us over time,” explained the Hubble Space Telescope’s team in a press release.

Even more impressive is the fact that the Virgo Cluster is moving away from our home galaxy, but there is Messier 90, a member of the cluster, which is getting closer to the Milky Way, a fact that makes it a rare galaxy.
