In the pre-merger hotline, astronomers first discovered the "wave bridge" between the two clusters.

We know that there are actually a series of "bridges" connected between the various galaxies and clusters of the universe. They are composed of dark matter, dust and gas, forming an orderly universe. Recently, astronomers have for the first time discovered a special "radio wave bridge" between two clusters of galaxies, stretching over 10 million light years and carrying magnetic fields, allowing scientists to learn more about the large-scale structure of the universe. In cosmic physics, fibrous structures are the largest known structures. These "fibers" are assumed to be composed of invisible dark matter and visible dust and gas. You can imagine that the structure of the universe is like a net, and those lines are thin. And the fibrous structure that is difficult to observe, the point where the line intersects the line is a galaxies or clusters of galaxies. As for the one-frame-shaped holes between the lines, we call them "Voids". These areas (in…

Japanese astronomers discovered more than 1,800 supernovas in six months

After Japanese researchers gathered data, they discovered about 1,800 new supernovas or exploding stars in half a year. These studies have helped to measure the speed of the expansion of the universe, which is a very surprising discovery. According to comprehensive media reports, supernovae are extremely rare. Only a few telescopes in the world can capture clear images. Even with the Hubble Space Telescope, it takes 10 years to discover 50 supernovas that are more than 8 billion light-years away from Earth. Researchers at the Kafiri Mathematical Cosmology Research Institute (Kavli IPMU) at the University of Tokyo, Japan, combined with the observations of the new generation of super wide-angle cameras (HSC) and the Pleiades telescope (also known as the Subaru Telescope), found 1,800 supernovae. Among them, 58 are type Ia supernovas 8 billion light-years away from the Earth.
Supernova is a violent explosion that some stars experience as they approach the end of the evolution. These explos…

Astronomers capture images of this binary system as the asteroid 1999 KW4 flies across the Earth

The 1999 KW4 asteroid passed the Earth at a safe distance of about 3.2 million miles. Space rock is far from enough to pose a threat to our planet, but this distance is enough for astronomers to capture the image of this "special visitor." Asteroid 1999 The KW4, unlike many other space rocks, is actually a binary system consisting of two separate space rocks: an asteroid about a mile in diameter and a small satellite that orbits it. The satellite is about 0.25 miles in diameter.
The European Southern Observatory has released an image of a binary system taken by the Very Large Telescope (VLT). The image of the dragonfly is the actual photograph taken by the scientist, and the image on the right is the artist's imagination of the artist about what they might look like.
"These data, combined with all the data obtained through the International Asteroids Early Warning Network (IAWN) activities on other telescopes, are critical to assessing effective deflection strategies w…

Astronomers say that the water found in the "Christmas Comet" is very similar to the water in the Earth.

Where does the water on the planet come from? This problem has been plaguing scientists for many years. An international team of astronomers tried to answer this question by studying the water found in the comet 46P / Wirtanen.
We have identified a huge reservoir on the periphery of the solar system, where the water is very similar to the water on Earth. "The first author of the study, Darek Lis, said in a statement.The study was published in the journal Astronomy and Astrophysics on May 20, and astronomers used NASA's Stratospheric Infrared Astronomical Observatory (SOFIA) to study the so-called "Christmas Comet" in 2018. Flying in the earth in December. The SOFIA Air Observatory was converted from a Boeing 747.A long-standing theory holds that the earth's water is from ice comets outside the solar system. The theory holds that when a comet collides with the early Earth, the impact brings water into the Earth's environment. To determine if the water in this …

Astronomers discover dozens of stars that have been "expelled from their homes"

According to foreign media BGR reports, astronomers used NASA's powerful Chandra X-ray Observatory to observe that some stars are often "expelled from their homes." Astronomers have discovered several binary systems. These binary stars consist of two stars that orbit around a common center. When a giant star explodes into a supernova and its core collapses into a dense neutron star, under certain conditions, these huge explosions that produce neutron stars are not symmetrical. "Asymmetric forces" may cause a star to be thrown at its intended location. And their companion stars will also be forced to leave the galaxy.
“It’s like a guest being invited to a party with a noisy friend,” Xiangyu Jin, the first author of the study, said in a statement. "The companion star in this case was dragged out of the galaxy just because it was in orbit with the supernova's star."
Researchers using Chandra data have discovered about 30 pairs of stars from the Fornax c…

Astronomers discover rare new galaxies on the verge of death

For the first time, an astrophysicist at the University of Kansas discovered an extremely rare galaxy that fundamentally changed the understanding of galaxies' deaths. At the 234th meeting of the American Astronomical Society on Thursday, Allison Kirkpatrick showed off her "cold quasar", a very bright, dying galaxy.

The center of the quasar is basically a huge supermassive black hole surrounded by a large amount of gas and dust. The surrounding material releases huge energy in the process of rapidly falling into the black hole in a way similar to "friction heat generation", making them super bright. - Brighter than ordinary galaxies. They can be generated when two galaxies are merged.Eventually, gas and dust will begin to fall into the center of the quasar and be blown into space. Astronomers speculate that this is basically the end of a galaxy's life, it has lost the ability to form new stars, and become "passive", but Kirkpatrick and her research…
