This cosmic optical illusion was first predicted by Albert Einstein.
The object GAL-CLUS-022058s in the constellation Fornax the Furnace is far more elegant and intriguing than its namesake. This an. is one of the largest and most complete examples ofever seen in the universe.
Now, since the original release of this image in 2020, scientists have determined that it is also a window into an early period of the early universe, when new stars were rapidly forming in the region, like a cosmic assembly line. was in operation.
Einstein’s ring is an example of an optical phenomenon first theorized by Albert Einstein called. The basic idea is that light from a distant object into deep space is distorted by the gravity of an object that lies between the distant object and the observer.
Here, the light from the background galaxy is not only distorted, but also magnified by a factor of 20. This allows astronomers to get a better look at the Milky Way than can be provided by currently available technology. In fact, the effect is comparable to that seen through a telescope with a 157-foot (48 m) wide aperture.
NASA breaks down exactly what we see in the image in this video:
Astronomers analyzed the image and built a model that determined the effects of gravitational warfare to accurately determine what they were seeing.
“Such a model can only be achieved with Hubble imaging,” explained principal investigator Anastasio Díaz-Sánchez of Spain’s Universidad Politecnica de Cartagena in a statement. “Specifically, Hubble helped us identify four duplicate images and stellar clumps of the lensed galaxy.”
The analysis allowed the team to determine that the background galaxy is 9.4 billion light-years from Earth, placing it in a region of space and time where peak formation is occurring a thousand times faster than what we see in the Milky Way. Was. Way.
This insight could help scientists explain why giant elliptical galaxies in the universe appear to form as we see it today. Plus, it’s fun to discover what is one of the largest natural funhouse mirrors in the universe.
