10 Mysterious Finds That Will Boggle Your Mind!

4. Oumuamua

Found Year: 2017 It was discovered by Dr. Robert Weryk. Where: Solar System Umuamua, which was discovered by Dr. Robert Weryk in 2017, has the appearance of a "giant space cucumber," is twice as reflective as a comet, and travels through space apart from the Sun's orbit. This is most likely because the comet's frozen gas, which is warmed by the Sun, gets an additional boost from the Sun.

The comet is thought to have entered our Solar System sometime during the Victorian era. Whether a probe or not, Umuamua has already orbited Jupiter and is moving slowly in the direction of the next star system.

5. The Star of Tabby

Found Year: 1890 It was discovered by Teresa Boyajian. Where: Cygnus Tabby's Star, which is located in the constellation Cygnus 1,500 light-years from Earth and is resting in its proper place, has been the subject of numerous discussions over the years. The majority of these have to do with the reason behind the star's occasional 22% brightness decrease, as opposed to the average planet's yearly brightness drop of less than 1%.

In any case, for years to come, astronomers will be baffled by the star that bears the name of Tabetha Boyajian.
