Research background:
Space is incredibly large and mysterious. We are unlikely to fully explore it before the end of humanity.
Every once in a while,We will discover some mysterious celestial bodies or observe some unexplained anomalies.
We rarely find answers to these mysteries.
What we do is brainstorm and think about what they can or cannot do.
However, some are so strange that we see them as evidence of the existence of some intelligent life.
Research purpose:
The background for studying these mysterious things has always been human curiosity and exploratory desire.
Scientists hope to understand the formation and essence of these phenomena,This will help us better understand the essence and evolution of the universe, as well as the universe we are in and the position of the Earth in the universe.
Omo
In October 2017, astronomers detected a mysterious object floating in our solar system.
They named it Aomo Mo. It flew very close to the sun - reaching a quarter of the distance between the sun and the earth - and then suddenly accelerated and fled our solar system.
Astronomers do not know what Omomo is, nor do they know the reason for its sudden acceleration.
Some astronomers believe that this is an abnormal comet. Others believe it is an asteroid, an incompletely formed planet, a solar sail, or a large ice block detached from a destroyed planet.
Shmuel Biali and Ivy Laueber from Harvard University suspect that Omomo is a solar sail, also known as a solar powered spacecraft.
Biali and Biali believe that sails were built by aliens to explore our solar system.
However, other astronomers do not agree. NASA'sZdenek Sekanina Believing that Omomo is an ice comet without a tail.
He believed that Omo lost the water and gas that formed its tail when it was too close to the sun.
Gregory Laughlin and his team at Yale University unanimously believe that Omomo is made of ice, although they do not consider it a comet.
They believe that,It was once part of a cold planet that was destroyed when it approached a larger planet.
Amaya Moro Martin of the Space Telescope Science Research Institute believes that Omomo is a remnant of a partially formed planet.
He and his team suspect that the planet was still forming when it was thrown out of the star system.
If this is true, then Omomo is the first incompletely formed planet we have discovered.
Tiger Spot Star
In 2011, scientists studying data captured by NASA's Johannes Kepler spacecraft found that a star named KIC8462852 often darkened before brightening again.
This star is also known as the star of Boyagian or the star of Tabi.
Scientists have proposed several reasons for this strange behavior.
Some people believe that dimming is caused by a group of comets orbiting stars or other unproven substances in our solar system.
Others believe that it is caused by the dust surrounding the black hole between Tabby and Earth.
A group of astronomers believe that,This effect is generated by giant structures built by certain intelligent beings.
They believe that,
This suggestion aroused great curiosity,Encouraging other scientists to attempt to determine the true cause of the dimming event.
In May 2017, dozens of telescopes observed the star as it darkened again.
Scientists quickly discovered that this was not caused by giant structures, as such objects would block all colors of constellar light from reaching the telescope, rather than simply darkening it.
Scientists have come to the conclusion that,The darkening effect is caused by the space dust orbiting the star.
However, they are unable to determine the source of the dust or confirm whether it is truly dust.
It seems that the dust has also been blown away from the star. That's why some scientists believe that an undiscovered celestial body is producing more dust to orbit the star.
In 2016, Brian Metzger of Columbia University proposed that dust was released from a planet or satellite that was destroyed too close to Tabby.
Rapid radio burst 121102
Rapid radio bursts are strong radio signals that we rarely receive from space.
Although scientists cannot confirm the source of these signals, researchers believe that they are sent by exploding stars or neutron star swallowed by black holes. Rapid radio bursts usually disappear as soon as they appear.
However, it is not a rapid radio burst 121102.
Since they received their first signal on November 2, 2012,Scientists have received over 150 signals from the rapid radio burst 121102.
Although they cannot confirm the exact source, scientists have traced these rapid radio bursts to distant galaxies 3 billion light years away.According to one theory, the signal comes from a neutron star.
However, another theory suggests that rapid radio bursts may have been launched by technology used by aliens to power their spacecraft.
Scientists do not believe that aliens intentionally sent these signals to contact us, as they were released three billion years ago.
At that time, human beings did not exist, and the earth was full of unicellular organism.
Undercurrent
Astronomers have identified a group of distant galaxies traveling at speeds exceeding 1.6 million kilometers per hour (1 million miles per hour).They don't know how or why galaxies move so fast, nor do they know where they are heading.
Nevertheless, they decided to call this mysterious movement the 'undercurrent'.
Astronomers suspect that dark currents are caused by large but undiscovered celestial bodies pulling galaxy clusters towards themselves.
The galaxy is currently moving away from Earth, but scientists do not rule out the possibility of this phenomenon reversing its direction and moving towards Earth in the future.
AT2018cow: N
In June 2018, a bright flash suddenly appeared somewhere in the constellation of Hercules, 200 million light-years away.
The flash is very bright, equivalent to the light emitted by 10-100 supernovae.
Scientists call it AT2018cow or "cow".
It remained bright for two weeks before it began to fade.
Scientists analyzed the X-ray and ultraviolet rays emitted by the flash and concluded that it was caused by the black hole devouring white dwarf.
However,Others believe that cattle are actually caused by black holes or neutron star formed after the death of stars
Mysterious signals from sun like stars
On May 15, 2015, astronomers operating the Russian telescope RATAN-600 detected a strange radio signal from a sunlike star 94 light-years away.
This star is called HD164595, almost like our sun.
Two stars have similar chemical properties and temperatures.
However,HD164595 1%1
Some astronomers suspect that this mysterious signal is released by aliens, because the star system containing HD164595 also has a Neptune like planet named HD164595b.
Scientists believe that this star system may contain other undiscovered planets, including an Earth like planet.
However,
Firstly, the astronomer who detected the signal did not notify anyone for a whole year.
In addition, the construction mode of the RATAN-600 telescope makes it difficult to accurately locate the exact position of the signal.
Therefore, the HD164595 satellite system may not even be a signal source.
In addition,Aliens need at least 50 trillion watts of energy to transmit signals to Earth.
This is more than the entire human race has ever used, and it is unlikely that aliens will gather such massive energy just to send us signals.
A mysterious super void
The space is filled with blank areas called gaps. Some voids are very large and are called supercavities.
On average, a supercavity can contain 10000 galaxies.
However, they do not, as they are usually not dense enough. One of the supercavities is one of the largest celestial bodies discovered in space.
The supercavity located 3 billion light-years away is very large, and even if an object travels at the speed of light, it takes hundreds of millions of years to pass through it.
Scientists need a three-dimensional map to locate and study this supercavity.
Strangely, scientists have discovered that supercavities can also absorb energy from the light passing through them.
As the universe expands, it will also continue to grow.
Mysterious Radio Signal of M82 Galaxy
In May 2009, British astronomers detected strange radio signals while monitoring an exploding sidereal time in M82 galaxy.
Radio signals from space usually become stronger within a few weeks before they begin to weaken.
However, M82
Some scientists believe that radio signals are emitted by a supermassive black hole in the M82 galaxy.
This makes sense because most galaxies have supermassive black holes, which emit radio waves right at their centers.
However, M82
Other scientists believe that,Radio waves are actually emitted by Microquasar, which are black holes formed when giant stars explode.
Microquasar are much smaller than supermassive black holes at the center of galaxies, although their masses are still 10 to 20 times the mass of the solar mass.
Some scientists believe that mysterious waves without X-rays cannot be emitted by Microquasar that emit both radio waves and X-rays.
However,There are indications that Microquasar may be located in an unusual environment that eliminates X-rays.
Zombie Star
A supernova is a large-scale explosion that occurs when a star runs out of fuel. It usually represents the beginning of the end of stellar life.
However,
In 1954, astronomers observed a massive iPTF14hls 500 million light-years awayThe star exploded into a bright supernova.
In 2014, they observed the same iPTF14hls star exploding again into a supernova.
Initially, astronomer Al Alcavi believed that the 2014 supernova was caused by a different star that somehow managed to reach the location of the star that exploded in 1954.
However,
Later, iPTF14hls was nicknamedZombie StarBecause it seems to be resurrecting from the dead.
Although iPTF14hls is still the only star observed with two explosions,But scientists believe that multiple explosions are common in stars with a mass of at least 100 suns.
Nevertheless, astronomers believe that iPTF14hls has died forever this time.
However, they may be wrong. A supernova shines brightly for three months, then gradually darkens.
The iPTF14hls has been shining for over two years.We may need to wait for decades before it erupts again.
Summary:
These studies will not only help us better understand the origin and evolution of the universe and life.
It will also provide valuable information for our future research and exploration.
