Astronomers have accidentally discovered a new galaxy 11 billion light-years away from Earth, thanks to the Hubble Space Telescope.

Astronomers were looking at another galaxy, SDSS J223010.47-081017.8, which they thought was a perfect reflection of the galaxy and its companion.

This discovery was made due to the gravitational lensing first predicted by Albert Einstein’s theory of general relativity.

This occurs when a large object such as a group of galaxies generates a gravitational force that distorts light from the galaxies behind it, but at the same time, NASA.

The effect is similar to that seen in a magnifying glass and allows researchers to detect never-before-seen galaxies using modern technology.

“We were very shocked,” said Timothy Hamilton, an astronomer at Shawney State University in Portsmouth, Ohio. A statement.

The reflected images are now called Hamilton’s subject, after Hamilton.

“My first thought was that they could contact the galaxies with clean, outstretched hands,” Hamilton added. “It doesn’t fit exactly, but I don’t know what to think.”

Hubble looked at the centers of active galaxies called quasars, which appeared to be a reflection of one of the two brightest images.

“Show the patterns of bright light at the bottom of the pool considering the wavy surface of the swimming pool on a sunny day,” Richard Griffiths, the study’s lead author, said in a statement.

These bright shapes below are caused by an effect similar to gravitational lenses. The ripples on the surface act like partial lenses and focus sunlight on the bright navigation patterns below.

The double body with a strange object nearby looked like the swelling of a galaxy.

The linear objects were actually determined to be rectangular shapes of distant galaxies.

Gravity lensing was predicted by Albert Einstein’s general theory of relativity.

Einstein’s theory was demonstrated in July, when scientists were able to see light for the first time from behind a black hole.

This phenomenon is caused by the gravitational pull of a dense dark matter, which forms the bulk of the mass of the universe.

Scientists cannot see the dark object (yet), but when light from a distant galaxy exits through the cluster, it forms two vitreous images and a third.

“This gravitational lens is very different from most lenses Hubble has read before, especially in the Hubble Frontier Fields survey of clusters,” Griffith explained.

You do not have to look at these groups for a long time to find many lenses. In that sense, it is the only lens we have. We didn’t know about the group at first. “

Gravity lens expert Jenny Wagner at the University of Heidelberg and Nicholas Tesser, another expert on gravitational lenses, have developed a plan to understand unique lenses and show that dark color should be “evenly distributed” around stretched images.

“It is very good that we only need two pictures of glass to measure how bitter or dark the material is under these conditions,” Wagner said.

“Here, we do not use any lens models. We can take notes from multiple photos and share them with each other. We can fold it together in our own way. It really gives us an idea of ​​how soft the dark material is in these two stages.”

However, 100 years after Griffiths’ discovery, the dark object remains a mystery.

We know this is a kind of thing, but we do not know what that particle is. So we have no idea how it works. We know that it has mass and is subject to gravity.

The importance of size limits over tumor or softness gives us some clues as to what a particle is.

The smaller the dark material, the larger the particles should be. “
