10 Mysterious Things We Have Discovered In Space

Space is unbelievably large and mysterious. It is unlikely that we will completely explore it before the end of humanity. Every once in a while, we discover some mysterious celestial body or observe some unexplainable anomalies.

We rarely have answers to these mysteries. All we do is brainstorm over what they could or could not be. Nevertheless, some are so weird that we have considered them as evidence of the existence of some intelligent life out there.

Oumuamua

In October 2017, astronomers detected a mysterious object floating through our solar system. They named it Oumuamua. It flew close to the Sun—reaching one-fourth the distance between the Sun and the Earth—before suddenly accelerating and escaping from our solar system.

Astronomers do not know what Oumuamua is or the cause of its sudden acceleration. Some astronomers have suggested that it is an abnormal comet. Others think it is an asteroid, a less than fully formed planet, a solar sail, or a large body of ice that broke off from a destroyed planet.

Shmuel Bialy and Avi Loeb of Harvard University suspect that Oumuamua is a solar sail, which is a solar-powered spacecraft. Bialy and Loeb think that the sail was built by aliens to explore our solar system.

However, other astronomers disagree. Zdenek Sekanina of NASA believes that Oumuamua is an icy comet without a tail. He suggested that Oumuamua lost the water and gases that would have formed its tail when it strayed too close to the Sun.

Gregory Laughlin and his team at Yale University agree that Oumuamua is made of ice even though they do not think it is a comet. They believe that it used to be part of an icy planet that was destroyed after straying close to a larger planet.

Amaya Moro-Martin of the Space Telescope Science Institute thinks that Oumuamua is the remnant of a partly formed planet. He and his team suspect that the planet was still forming at the time it was flung out of its star system. If this is true, Oumuamua is the first less than fully formed planet we have found. space space science space physics science space space science space physics science

Tabby’s Star

In 2011, scientists studying data captured by NASA’s Kepler spacecraft discovered that a star named KIC 8462852 frequently dimmed before brightening up again. The star is also known as Boyajian’s star or Tabby’s star.

Scientists proposed several causes for this bizarre behavior. Some suggested that the dimming was caused by a group of comets orbiting the star or some other unconfirmed materials in our solar system. Others think that it is caused by the dust around a black hole between Tabby’s star and Earth.

One group of astronomers believed that this effect was generated by a megastructure built by some intelligent life. They think that the star dimmed when the orbiting megastructure passed between the star and the Kepler space telescope. This suggestion generated the most curiosity, causing other scientists to try to determine the real cause of the dimming event.

Dozens of telescopes observed the star when it dimmed again in May 2017. Scientists soon discovered that this was not caused by a megastructure because such an object would block all colors of the star’s light from reaching the telescopes rather than simply dimming it. Scientists concluded that the dimming effect happened due to space dust orbiting the star.

However, they could not decide on the origin of the dust or confirm whether it is really dust. It also seems like the dust is being blown away from the star. This is why some scientists think that an undiscovered celestial body is creating more dust to orbit the star.

In 2016, Brian Metzger of Columbia University suggested that the dust was released from a planet or moon destroyed after straying too close to Tabby’s star.
