An extraordinary new shot from the Hubble Space Telescope shows Messier 90, a spiral galaxy, about 60 million light years from our Milky Way – but we are approaching.
While the image itself is extraordinary, the information found by astronomers is increasingly exciting. According to Hubble, the 90th Messiah is one of several galaxies that enter the Milky Way. Scientists can understand that galaxies approach us because light comes from the Messiah 90.
“Galaxies compress their wavelengths as they move towards us, when pressed at one end,” Hubble said. Under the visible light spectrum, short wavelengths appear blue. While light is condensed from our point of view, Messier 90 shows a phenomenon called “blue arrows” which shows scientists that the Messiah 90 approached us.

Almost all the other galaxies that we can observe move away from us with the expansion of the universe, Hubble said. We see how the light expands to the red end of the visible light spectrum (called redshift).
Messiah 90 is part of the Virgo Group, a group of more than 1,200 galaxies. Astronomers say that Messier 90’s blue shift may be caused by an extraordinary part of the cluster, which speeds up the galaxies in the belt to high speeds and places them in strange orbits. According to Hubble’s statement, strange galaxy paths send them to us and us from time to time.
A group of girls move away from us, said the Hubble representative, but some galaxies in clusters, including Messiah 90, move faster than the whole cluster. From the point of view of the Earth, we see galaxies moving towards us, even though other galaxies in the same group seem to move away at high speed.
This special Hubble image from Messier 90 combines infrared, ultraviolet and visible light. Because the camera of the shooting consists of four light detectors with overlapping fields of view – one with a magnification greater than the other three – the image is placed with a stair shaped opening at the top.
