The universe that surrounds us is an intriguing and incomprehensibly vast space that spans over the area of 93 billion light-years. To make it easier to imagine, it would take 100,000 years for light to travel to the end of our own galaxy, the Milky Way. In such a vast territory, it is not surprising that scientists have found some extraordinary objects.
KIC 846285: A Star With A Potentiometer?
This star was discovered by an astronomer from Louisiana State University, called Tabetha Boyajian, and is often referred to as Tabby’s star. Boyaijian and her colleagues spotted a space object that behaves strangely. Tabby’s star would decrease its brightness by 22 percent in intervals that had no logical sense.
The first theory of aliens having their hands in this was rejected, and the most plausible theory explaining the dips in brightness tells us how the star is surrounded by rings that cause the star to darken from time to time.
Haumea: The High-Speed Dwarf
Haumea belongs to a dwarf type of planets, and it is located in the Kuiper Belt. The fact that it orbits beyond Neptune is already strange enough. This object continues to dazzle even more with its weird prolonged shape, the fact that it has two moons and that the day cycle lasts only four hours. This is the fastest spinning object in our solar system. One peculiar thing was also noticed in 2017 - it has unusual thin rings that orbit around it, which probably came after Haumea collided with another space object millions of years ago.
Hyperion: Shooting Particles
This object is really not ‘’that’’ far away, and is one of the moons that is orbiting Saturn. The shape of Hyperion is somewhat unusual, as it looks like a spiked-shaped mountain, with many craters diving deep into its surface. However, the weirdest thing about Hyperion is that it basically has a cannon-like character. It is driven by static electricity, which allows the moon to shoot particle beams out into space.
Horologium-Reticulum Supercluster: Space Giant
This space formation, with its closest part around 700 million light-years away from our planet is so big the scientists are not even sure how big exactly. This supercluster contains a staggering amount of 350,000 galaxies. It is estimated that it would take you 550 million light-years to travel across Horologium-Reticulum Supercluster.
One thing that will happen in this structure relatively soon is the creation of even more galaxies. This will primarily affect the Abell 3266 region, because of an enormous cloud of gas that is approaching the territory. When it finally arrives, it will start another era of galaxy formation.
Eridanus: Supervoid Or A Parallel Universe?
Across its 93 billion light-years area, the universe is mostly empty. But, there is always something: gas, any energy, or atomic particles. However, this is not the case with the Eridanus Supervoid. An area that covers approximately 1 billion light-years in the Eridanus constellation does not contain anything.
There are no stars, no planets, no galaxies, and no dark matter. Two theories are explaining this supervoid. First, one argues that the Eridanus supervoid is maybe home to another universe inside a black hole. Another one speculates that the supervoid is a signature of a parallel universe that was once in contact with our own billions of years ago.
How large is the Eridanus Supervoid?
An area that covers approximately 1 billion light-years.
