Spooky universe: 5 scariest objects are besieging Earth

A tunnel that swallows the entire solar system, a "bomb crater" in the middle of a galaxy containing Earth or a jellyfish "returned from the dead" suddenly appeared in the sky . are the most shocking discoveries of the astronomer world. in the last year.

Live Science has reviewed the "unbelievable" objects from the universe that have just been revealed in 2021.

1. "Ghost jellyfish" from the dead

Not visible to the naked eye, but radio telescopes have captured a shocking image of one or two bright, transparent "jellyfish" appearing in the sky, from the galaxy cluster Abell 2877 miles away. us 300 million light years.

Like ghostly jellyfish or jelly cubes, the structure is aptly named "radio phoenix", believed to be the result of a black hole explosion.

2. The Great Wall of the "heart" of the Milky Way

Research published in November in Nature Communications has shown that an invisible wall wraps around the center of the galaxy containing the Earth's Milky Way (the Milky Way), making it impossible for fierce cosmic rays to strike. Most likely this wall is related to the monster black hole located in the center of the galaxy.

3. The galaxy containing the Earth has a hole in it

A 500 light-year wide cavity called Perseus - Taurus Supershell, like a giant ball with absolutely nothing inside, has been discovered right in our own galaxy.

The hole, observed by the European Space Agency's (ESA) Gaia space observatory, is believed to be the remnant of a catastrophic supernova explosion. Supernova explosions are the final death of a star.

4. Magnetic tunnels surround the whole solar system

Studying the two brightest radio-emitting gas structures in the sky, the North Polar Spur and the Fan Region, scientists found they appeared to be linked together by long, twisted strings of charged particles. , which generates a strong magnetic field. These strings stick together to form a giant tube, or can be said to be a terrifying magnetic tunnel in which the whole solar system and many surrounding stars are nestled.

5. Mysterious hut on. the moon

An inexplicable structure of China's Yutu 2 rover probe, operating on the moon, captured on October 29. The object juts out just above the horizon and is completely unnatural, leading many to suspect evidence of an extraterrestrial civilization.

China's National Space Administration (CNSA) said Yutu 2 will need at least three months for a clearer review.
