10 202 1 The strangest spatial structure discovered.

The closer we get to the universe, the more beautiful and puzzling it will become.

Hubble Space Telescope runs more than 300 miles (480 kilometers) above the earth, tens of millions of light-years away from many interstellar objects it studies, bringing "teleworking" to a new extreme. In the year when the world below was popular again, strange and wonderful space discoveries poured in from above, and astronomers uncovered the cosmic treasure house of monster black holes, invisible magnetic giant structures and alien planets.

To remind you, the farther away from the earth, the weirder the universe will become. The following is the most awesome, extreme and mysterious spatial structure discovered by 10 202 1.

They say that in space, no one can hear you. Tell Pac-Man that the gas residue of an ancient supernova presents a shape that fans of classic video games can immediately recognize. The celestial body, officially named N 63A, is the product of the collapse of a star in the large magellanic cloud not too far away from the Milky Way 163000 light years. The diffusion of superheated gas occasionally assumes this shape. But the bright "energy projectile" sitting on Pac-Man's path is no coincidence. According to NASA researchers, these particles are young stars forged from the same gas cloud that carried Pac-Man's unfortunate ancestor star a long time ago. It's a pity ... it seems that the star's life has run out.

Cluster of galaxies is the largest known structure in the universe, which is held together by gravity. They may contain thousands of galaxies, huge hot gas clouds, and sometimes there are one or two glowing ghosts of jellyfish. Astronomers found such a jellyfish in the galaxy cluster Yinling 2877 in the southern sky about 300 million light-years away from the Earth. The width of cosmic jelly is over 65.438+0 billion light years, which is only visible in narrow-band radio light.

According to a study published in the Journal of Astrophysics on March 17, such a large structure has never been seen in such a narrow band of light. Perhaps this cosmic jelly is actually a "radio phoenix"-a cosmic structure produced by high-energy explosions (such as black hole explosions). With the expansion of the structure and the loss of electron energy, it gradually disappeared after millions of years, and finally it was revived by another cosmic disaster (such as the collision of two galaxies). The result is a huge structure that emits bright light at some radio frequencies, but quickly darkens at all other frequencies. Ghost, jellyfish, phoenix, three in one!

Stop sneezing, Orion! This year, scientists have found convincing evidence that the rarest planet in the universe-a world orbiting three stars at the same time-lives at the top of the huge gas-filled nose of Hunter.

The star system called GW Orionis (or GW Ori) is about 1 300 light-years away from the earth, which is an attractive research target. Three dusty orange rings are nested with each other, and the system looks like a huge bull's-eye in the sky. At the center of the bull's-eye are three stars-two locked in close binary orbits and the third revolving around the other two. In a paper published in the Monthly Journal of the Royal Astronomical Society on September 17, based on previous data, the researchers showed that the wobble misalignment in the three rings of the star system was almost certainly caused by the existence of a large planet the size of Jupiter in one of the rings. If future research proves that this huge world will be the first planet found in the universe to "orbit", or a planet orbiting three stars-and will make luke skywalker's twin sun star Tatooine really make money.

In 20 19, researchers released the first (and only one so far) photo of a supermassive black hole, which is a huge object with a mass about 6.5 billion times that of the sun, located in messier 87 galaxy about 55 million light years away from the earth. This year, scientists used the Super Array Observatory in New Mexico to observe this behemoth again, and now focus on the huge jet of matter and energy ejected from the center of the black hole. The analysis of the research team shows that this huge jet is not direct, but twisted into a strange "double spiral" structure by a spiral magnetic field, which is ejected from the black hole and goes deep into space for nearly 3300 light years. The researchers said that this is the longest magnetic field detected in the Yinhe jet so far.

The center of the Milky Way is like a giant particle accelerator, emitting a beam of charged matter called cosmic rays to the universe at a speed close to the speed of light. In a study published in Nature Communication on October 9th, 165438/kloc-0, when researchers tried to draw the density map of cosmic rays near the center of the Milky Way, they found a puzzling thing: even if cosmic rays gushed out from the center of the Milky Way, there was still a mysterious "barrier" that prevented most cosmic rays from entering the center. The team can only speculate on the source of this cosmic ray barrier, but think it may be a chaotic magnetic field related to the huge Sagittarius A* in the black hole at the center of our galaxy.

In a study published in Astronomy and Astrophysics on October 26th, 65438/KLOC-0, scientists shared the discovery of a huge "shipyard" where galaxies were built, similar to the place where our Milky Way grew up. This huge structure, called protogalaxy cluster, contains more than 60 galaxies, which are light years away from the earth 1 1 100 million. It is only a part of the 3 billion-year history of the universe. Protogalaxy clusters like this are formed in space, where long gas lines called filaments crisscross, providing a lot of hydrogen for gravity, thus condensing into stars and galaxies. Researchers say that the young galaxies gathered in this "shipyard" seem to be growing at a greedy and almost unrealistic rate. This discovery shows that ancient primitive clusters are much more effective than researchers thought in assembling the foundation of the modern universe.

Two clouds with similar momentum are discharged side by side in a beautiful galaxy. These huge star-forming gas regions are called "molecular clusters", which span the sky and seem to form a bridge between Taurus and Perseus. This is a fable about Starlight Glimmer's love-and, according to recent research, it is also a huge optical illusion.

The new 3D map of the region provided by the Gaia Space Observatory of the European Space Agency shows that these hanging clouds are actually hundreds of light years apart, separated by a huge empty sphere completely free of gas, dust and stars. According to a study published on September 22nd, this newly discovered crack is called Perseus-Taurus Supershell, which is about 500 light years wide. The Astrophysics Journal Express was probably caused by a catastrophic supernova millions of years ago. The good news, the researchers wrote, is that the ancient explosion may have accelerated the formation of stars at the edge of the super shell, which brought a happy ending to this tragedy in Starlight Glimmer.

The earth, as well as other parts of the solar system and some nearby stars, may be trapped in a huge magnetic tunnel-astronomers don't know why. Astronomers proposed in a paper on the preprint database arXiv that a huge magnetized tendril tube 1 0,000 light years long is invisible to the naked eye and may surround the solar system. The team's investigation of the two brightest radio emission gas structures near our Milky Way galaxy-the Arctic tributary and the sector-shows that these two structures may be interrelated, even if they are located on different sides of the sky. The researchers said that the glue connecting these structures is long and twisted tendrils of charged particles and magnetic fields, similar to a "winding tunnel" that surrounds everything between them, including the solar system. The author points out that the source of this magnetic "tunnel" is not clear at present, but tendrils like this may be everywhere in the universe and may be part of an all-encompassing crisscross magnetic field network.

Black holes are messy diners. When unfortunate stars venture too close to these greedy objects, the extreme gravity of black holes will stretch the stars into noodles, a process called "spaghetti". In May this year, researchers first saw this chaotic process directly, when a black hole 750 million light-years away from the earth and 30 million times the mass of the sun trapped a passing star in its clutches. The disastrous encounter produced a bright flash, and the X-ray telescope on the earth could clearly detect radio waves. But it also reveals the unusual absorption line pattern around the pole of the black hole, showing that a long light has wound around the black hole many times, just like a ball of wool. Since most absorption lines usually appear near the equator of black holes, the researchers concluded that they must be witnessing the spaghetti of stars. Now, how do they send huge napkins to another galaxy?

Finally, what about the "mysterious hut" proudly standing on the back of the moon for the celestial bodies closer to home described this year? 10 year 10 On October 29th, China's Yutu No.2 rover discovered the abnormality of this cube shape, and the object protruded above the original even horizon. Is it stanley kubrick 200 1: an alien obelisk in a space odyssey? Or something more boring, such as one of the many boulders on the moon? According to China's National Space Administration, Yutu needs two or three months to observe carefully-and hope to get a satisfactory answer. Until then, we will look up at the sky happily.
