It seems that 6 galaxies can be seen in the image. Actually, it’s different.
–
which one Hubble Telescope He has a great image for someone Einstein ring made. This effect occurs when galaxies act as gravitational lenses. Because Einstein predicted this effect through his theory of relativity, this phenomenon is called Einstein’s ring.
In the picture, you can see a near -perfect circle, with 2 luminous galaxies are in the center and 4 more galaxies can be found in the circle. In fact, there are only three galaxies depicted here. In fact, to be precise, they just 2 distant galaxies and quasars.
–
The quasar in the center looks like two dots. The two galaxies are in a circle and they look like 4 galaxies in the picture. Because the masses of these two galaxies in the foreground are very large, one of them has been created Bending in the continuum of space and time. Then this light traveling through this succession of space-time reaches our telescope in a distorted, but at the same time amplified, way. In this case, the Hubble Space Telescope.
–
This effect is not only beautiful to look at, but can also be used consciously by astronomers. Then the gravitational lens acts as a kind of magnifying glass to see into the depths of space. In addition, the size of the distortion can be used to calculate the mass of the galaxy.
–
But gravitational lenses could also be useful in our galaxy, for example black hole track and around Explore the outer planets To find those who broke away from their star system.
