Astronomers have accidentally discovered a new galaxy 11 billion light years away from Earth

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.

Using Hubble, astronomers discovered a new galaxy 11 billion light-years away. They found the galaxy SDSS J223010.47-081017.8 and the exact reflection of the galaxy and its companion.

“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 first saw light from behind a black hole.

What is a Gravity Lens?

Gravitational lensing occurs when light emitted from a distant galaxy is reflected by a larger galaxy or galaxy.

This creates a very detailed image.

This is because massive objects bend around them and light travels in a different direction.

This theory was first proposed by Einstein in his theory of general relativity.

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. “

This study was recently published Monthly Announcements of the Royal Astronomical Society.

Scientists study the atmosphere of distant aliens using large space satellites such as Hubble

Distant stars and the planets that orbit them often have conditions unlike anything we see in our atmosphere.

To understand this new world and its components, scientists need to figure out what is in their atmosphere.

They often do this with a telescope similar to NASA’s Hubble telescope.

These giant satellites scan the sky and trap aliens who think NASA might be interested.

Here, internal sensors perform various analyzes.

One of the most important and effective is called the absorption spectrum.

This analysis measures the light emitted by the planet’s atmosphere.

Each gas absorbs a slightly different wavelength of light, resulting in a black line appearing at full angle.

These lines correspond to a specific molecule, which indicates its presence on the planet.

They are often referred to as the Franhofer Lines, named after the German astronomer and physicist who first discovered them in 1814.

By combining different wavelengths of light, scientists can identify all the chemicals that make up the planet’s atmosphere.

The main thing is that the lost provide clues to find the present.

Since the Earth’s atmosphere is interfering, it is important that this be done using a space telescope.

Absorption from chemicals in the atmosphere will distract the sample, which is why it is important to study it before light has a chance to reach Earth.

It is often used to search for helium, sodium and oxygen in exotic atmospheres.
