The “curved” galaxies, according to researchers, have the usual shape. And they become curved due to distorted light.
Researchers captured an image of a large number of “curved” galaxies taken by the Hubble telescope and published the image on the device’s observatory website.
It is reported that in this way scientists have demonstrated the concept of a phenomenon called gravitational lensing.
In amongst the tiny dots, spirals, and ovals that are the galaxies that belong to the cluster, there are several distinct crescent shapes. Crescent-shaped arc curves are examples of gravitational lensing. According to the researchers, these are light arcs.

The gravitational phenomenon occurs when an object’s mass causes light to bend.
“The curved crescents and s-shapes of light in this image are not curved galaxies, but are light from galaxies that actually lie beyond Abell 2813,” the message said.
It is emphasized that galaxies cluster into a large mass and then act like a gravitational lens. Thus, they force the light from distant galaxies to bend around it. Distortion takes many forms.
