Earth and space observation instruments record data from our nearest neighbors in the universe to outer space. The Hubble Space Telescope orbits the Earth more than 480 kilometers away, tens of millions of light-years away from many of the interstellar objects it studies, but it continues to do so well. Now the James Webb Space Telescope is set to take a first look at Cosmic Structures in the coming months to revolutionize astronomical discoveries.

Even a year has passed, and while the universe has struggled with a corona epidemic, strange space discoveries such as the discovery of the mysteries of supermassive black holes and magnetic superstructures The invisibility and discovery of extrasolar planets continued and opened the human eye to more beauties and wonders of the universe. We review the most amazing, intense and mysterious space Structures Discovered in 2021.
1. Star Trek Packman in the Southern Sky
Last year, scientists identified the remains of a star very similar to Peckman, which is well recognizable to fans of this classic video game. Officially named N 63A, it is the remnant of a star that collapsed under its massive mass in the Large Magellanic Cloud 163,000 light-years from the Milky Way.

The scattering of superheated gas accidentally took this form. But the bullets of brilliant power that are in the path of the Cosmic pack are not accidental. According to NASA researchers, these bullets are young stars made of the same gas cloud that formed Peckman's main star long ago. Now, however, its life is over.
2. Spirit-like mermaids from the underworld
Galactic clusters are the largest known Structures in the universe, interconnected by gravity. They can include thousands of galaxies, huge clouds of hot gas, and sometimes glowing spirits of one or two mermaid-like structures. Astronomers have Discovered one of these mermaids in the Abell 2877 galaxy cluster in the southern hemisphere sky, 300 million light-years from Earth. A Cosmic jelly that can only be seen in a narrow band of radio waves and is more than 1 million light-years across.

Based on studies Published in the Astrophysical Journal on March 17, 2016, no structure of this size has ever been seen in such a narrow strip of light. This Cosmic jelly may actually be a "radio phoenix." It is re-energized by another massive Cosmic event (such as the collision of two galaxies). The result is a massive structure that glows brightly on certain radio frequencies but disappears quickly on other radio frequencies. This is a ghost, a mermaid and a Cosmic phoenix!
3. A very rare planet in the nose of a hunter
In 2021, scientists found compelling evidence that the rarest type of planet in the universe, a single universe orbiting three stars simultaneously, is at the tip of the constellation's large, gaseous nose. It is located in Orion.
A star system known as GW Orionis is located 1,300 light-years from Earth. It is a tempting goal to study. With three dusty and orange rings stacked inside each other, the system literally looks like a giant bull's eye in the sky.

There are three stars in the center of this cow's eye, two stars locked together in a tight binary orbit, and a third orbiting the other two stars extensively. In an article published September 17 (September 26) in the Monthly Notices of the Royal Astronomical Society, the researchers found that a vibrating inconsistency in the three rings of a stellar system was approximately equal to Definitely created by the existence of a planet the size of Jupiter inside one of the rings. If confirmed by future research, this vast universe will become the first planet Discovered around a triangle or a planet orbiting three stars.
Black hole energy spiral launch
In 2019, researchers take the first, and only ever, first image of a black hole, a giant structure about 6.5 billion times the mass of the Sun 55 million light-years from Earth in the Messianic Galaxy. Released 87 (M87). In 2021, scientists re-examined the massive mass using the Very Large Array Observatory in New Mexico, this time focusing on the massive streams of matter and energy erupting from the center of the black hole.

5. Invisible barrier protecting the center of the galaxy
The center of the Milky Way galaxy acts as an accelerator of giant particles, spewing rays of charged matter called Cosmic rays into the universe at speeds close to the speed of light. But when researchers tried to map the density of Cosmic rays near the center of the galaxy in a November 9 study in Nature Communications, they found something very puzzling.

Even when Cosmic rays erupted en masse from the center of the galaxy, there was a mysterious barrier against them that prevented a large portion of the Cosmic rays from entering the central regions of the galaxy. The team was only able to speculate about the source of this Cosmic ray barrier, suggesting that it could be a perturbation of the magnetic fields associated with the central black hole of our galaxy, Sagittarius A.
6. In a study published in the journal Astronomy & Astrophysics
on October 26, scientists announced the discovery of a massive
Cosmic shipyard where galaxies are built. , Similar to the
structure in which our Milky Way grew.
This giant structure, called the Protocluster, contains more than 60 galaxies, 11 billion light-years from Earth. This cluster is located in a part of the universe that is only 3 billion years old.

Prepositions like this form in areas of space where long bands of gas, called filaments, collide, providing a set of hydrogen to merge gravity into stars and galaxies.
7. A 500-light-year hole in the Milky Way
Two gas clouds, both similarly located in the Milky Way galaxy. These massive states of stellar gases, known as "molecular clusters," are stretched across the sky and appear to form a bridge between the constellations of Taurus and Bersavus. This is a celestial love story of the stars and according to recent research it is also a huge visual error.

Three-dimensional maps A new study from this region, prepared by the European Space Agency's Gaya Space Observatory, shows that these wavy clouds are actually hundreds of light-years apart and are covered by a huge, completely empty sphere without gas, dust and stars. They are separated.
- A huge mysterious hole 500
light-years across in the Milky Way has been Discovered The
newly Discovered hole, called the Perseus-Taurus Supershell,
is about 500 light-years across. And probably millions of years ago
by a supernova It has been created enormously and catastrophically.
According to researchers, this ancient explosion may have
accelerated the formation of stars at the edges of the superbubble,
ending the stellar collision tragedy.
The Solar System in a Magnetic Tunnel
The Earth, along with other solar system objects and some nearby stars, may be trapped inside a giant magnetic tunnel, but astronomers still do not know why. In an article published in the arXiv preprint database, the researchers suggested that a tube of massive magnetic rotations, 1,000 light-years across, with the naked eye invisible to the solar system.

The team's research on two of the brightest gas Structures that have developed in our galactic neighborhood, the North Polar Spur and the Fan Region, showed that with Although these two Structures are located on two different sides of the sky, they may be related. According to researchers, these Structures are connected by long, twisting cycles of charged particles and magnetic fields that, like a curved tunnel, cover everything in between, including the solar system.
It is not clear. Where did this magnetic tunnel come from, but the authors of the article suggested that torsional Structures like this could exist anywhere in the world and were probably part of a pervasive network of intersecting lines of magnetic fields.
9. A first look at a spaghetti star
Black holes are all-powerful omnivores. When an unlucky star approaches one of these objects, the black hole's intense gravity pulls the star toward it in a long string process called spaghetti. In May, researchers first observed this irregular process directly, during which a black hole 750 million light-years from Earth, 30 million times the mass of the Sun, trapped a passing star in its grip.

This catastrophic encounter of flash (instantaneous light) produced a glow of light in the visible spectrum, X-rays and radio waves that telescopes on Earth could clearly detect. The observations also showed an unusual pattern of absorption emission spectral lines around the black hole poles, in which a strand of light, like a cotton ball, is repeatedly wrapped around the black hole. Because most of the absorption lines usually appear near the equator's black hole, it turns out that scientists are actually watching the spaghetti process of stars.
