Strange and mysterious things in the universe you may not know

Strange galaxies, planets with unknown features, mysterious satellites and unique phenomena.

Mars has the largest volcano: Although Mars seems pretty quiet today, something in the past caused giant volcanoes to form and erupt. Among them is Olympus Mons, the largest volcano ever discovered in the Solar System. Stretching over 602 km, this volcano is the size of the state of Arizona (USA). Its height is 25km - 3 times higher than Everest - the highest mountain on Earth. Volcanoes on Mars are enormous in size because gravity on the Red Planet is much weaker than on Earth. However, how these volcanoes formed remains a mystery.

Mars also has the longest valley: At 4,000 km long, the Valles Marineris valley on Mars is 10 times longer than the Grand Canyon on Earth. Valles Marineris was discovered by the Mariner 9 spacecraft in 1971. The lack of active tectonic plates on Mars makes it difficult to explain how this canyon was formed. Some scientists even think that there is a chain of volcanoes on the other side of the planet, known as the Tharsis Ridge, that somehow bent the crust from the opposite side of Mars and created the valley. Valles Marineris.

Super Winds Venus: Venus is a "hell" planet with high temperatures and high pressures on its surface. Not only that, but the environment here is extremely harsh when scientists discovered that the wind on Venus blows 50 times faster than the planet's rotation speed.

Pinwheel galaxy with a double nucleus: Messier 83 is a large spiral galaxy located 15 million light-years away in the constellation Hydra. It appears to have a central double nucleus, perhaps two supermassive black holes or the effect of a disc of skewed stars orbiting a central black hole. Messier 83 is also home to many supernova explosions. Astronomers have directly observed six of these supernova explosions in this galaxy, along with the remnants of 300 more.

There may be life somewhere in the Solar System: So far, scientists have not found evidence that life exists somewhere in the Solar System. However, our understanding of polar microorganisms living in craters or in frozen environments has opened up the possibility that they could live on other planets. It is possible that no aliens have ever lived on Mars, but microorganisms that exist in the Solar System are likely.

"Tadpoles" in space: 300 million light-years away, there is a "tadpole" galaxy moving through space. This galaxy has a tail 500,000 light years long, 10 times longer than the Milky Way. What causes this galaxy's strange shape? According to researchers discovered in 2018, the cause was a collision between galaxies in the universe.

Wandering Planets: Galactic drifts are wandering planets that have been ejected from their parent star due to gravity. Among these is SIMP J01365663+0933473, a planet-sized object located 200 light-years away with a magnetic field 200 times stronger than that of Jupiter. Its magnetic field is strong enough to produce auroras in the atmosphere and can be seen through radio telescopes.

There are mountains on Pluto: Pluto is a tiny world located at the edge of the Solar System. An interesting discovery is that there are ice mountains up to 3,300 meters high on this planet, suggesting that Pluto was definitely geographically active at least 100 million years ago. Geography requires energy, however, and the source of that energy inside Pluto remains a mystery. The sun is too far away from Pluto to generate enough heat for this geologic activity, and there are no major planets nearby to create such mountains by gravity.

Jellyfish-like galaxy: Located in the constellation Triangulum Australe (Southern Triangle), galaxy ESO 137-001 looks like a jellyfish swimming among the sea of ​​stars. According to NASA, stars are forming inside its "tail" of dust and gas (invisible to the naked eye) and this formation process is still a mystery because the gas in the tail is too hot for formation. become a star.
