James Web Space Telescope (JWST) has captured a stunning image of a bizarre celestial optical illusion.
This is called “rare cosmic event”, An Einstein RingThe darkness of space appears as a single eye -like orb, but in fact the constellation hydrus has a distorted view of two distance galaxies.
The bright center of this cosmic spectacle has a galaxy, while the orange and blue color spread around it is light from another galaxy located behind it. The light from a more distant galaxy looks like a ring because it is distorted by gravity lensing.
Gravity launching occurs when the gravity of a huge object – such as a galaxy or a black hole – bends the light from a far -fetched object. This effect is the direct result of Einstein Theory of relativityWhich suggests that the mass attacks the space-time fabric, allowing the light to follow the winding paths, such as a ball rolls a curved slope.
Representative of ESA “This effect is very subtle to be seen locally, but it sometimes becomes clearly viewable.” It is written in a statement.
This latest image was released by ESA and Canadian Space Agency today (March 27) as their march. Month photo, This was captured by JWST-infrared camera instrument and also includes data for the wide field camera 3 data and advanced camera for survey equipment on the Hubble Space Telescope.

Einstein rings Such as a distant light source, large -scale lensing objects, and the observer are fully aligned, resulting in a full ring wrapped around the light lensing object. As a result, they are rare.
In this case, the elliptical galaxy in the foreground-which is part of a galaxy cluster called smacsj0028.2-7537-so much is so big that it is bending the light of the spiral galaxy located behind it.
According to the statement, “Even though its image has been seen as a trip around the galaxy in his way, but according to the statement, individual star clusters and gas structures are clearly visible.”
The attractive event of gravity lensing also allows astronomers to better understand the universe.
The light emitted from distant galaxies, which was present in the past long ago, is often very unconscious to be seen directly from Earth. Strong gravitational lenses increase these galaxies, allowing them to look large and bright, and allow astronomers to study the galaxies before the big bang.
The ESA statement said, “Such items are ideal laboratory in which it is very unconscious and away to research galaxies.”
Additionally, because black hole And dark matter Do not emit light, scientists can use gravitational lensing to detect and study these events, measuring how they bend and enhance the background stars.
