It is possible to take advantage of the ability of gravity (gravitational force) to bend space-time, which keeps everything in the cosmos in the middle, to see distant objects, which are very difficult to see in the ordinary. predicted by Einstein and gravitational lensing
This effect, named , is detailed in a new image from the Hubble Space Telescope.
In the middle of the photograph, a bright, face-like structure is seen, surrounded by four bright spots. In the middle of these dots, there are two more glowing golden dots. It is called the Einstein ring and there are three galaxies in the photo, not six; While two of them are in the middle of the ring, a quasar (stellar celestial body) is behind it. The light of the back galaxy is the light of the two foreground galaxies. distorts and enlarges as it passes through the gravitational field.
Gravitational curvature magnifies the view reaching the telescopes
Because the mass of the two foreground galaxies is very high, a cultivating curvature in space-time is occurring. A random light passing through this space-time follows this curvature and reaches the telescopes in a distorted but just-in-time magnified form.
It is indeed a useful tool for investigating both the far and near points of the universe. have enough mass everything can act as a gravitational lens. This could mean one or two galaxies, as we see here, or massive galaxy clusters that produce a gorgeous light spot from many objects behind them.
Distant galaxies can be viewed in much greater detail
Astronomers probing the depths of space need to see distant galaxies lensed in this state in much finer detail. can reconstruct these light spots and copied images. But that’s not all gravitational lensing can do. The strength of a lens is due to the curvature of its gravitational field, which is directly related to the mass around which it revolves.
In this way, gravitational lenses can help weigh galaxies and clusters of galaxies; which can then help locate and map the dark element. Gravitational lensing is another way around the Milky Way, such as stellar-mass black holes. helps us find objects that are too dark for us to see. might help.
Astronomers have identified cold and lonely rogue exoplanets that roam the galaxy independently of a host star, formed as Earth and distant stars pass midway through. they were able to detect it thanks to magnification. They even used gravitational lensing to detect exoplanets in other galaxies.
