Which of these scientific discoveries was confirmed in 1758? Halley's Comet, gravity, Bernoulli's Principle or penicillin. Even though Edmond Halley died in 1742, his prediction that the famous comet would return came true in 1758.
Scientists say that back in October 2017, the first interstellar object that's ever been observed flew through our solar system. They estimated it was traveling at 196,000 miles per hour and since then it has disappeared but they've continued to study and try to understand it ever since.
At first, researchers thought it could have been a comet but in comparing it to another interstellar comet, this one, they found that the new object had a mysterious tumbling motion as it flew and that it didn't have a commentary tail. Now there's a new theory that the pancake shaped object was part of a dwarf planet like Pluto that somehow broke off from another solar system and traveled near ours.
