Two massive clouds of dust in orbit around the Earth have been discussed for years and finally proven to exist.
- Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
- These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
- The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
We may not find Klingons, but what we do find will blow our terrestrial minds.
- Want to place a bet on when we'll discover alien life? NASA's Michelle Thaller thinks it'll be within the next 50 years.
- "I actually have a bottle of champagne chilling because I think it could happen almost any day, when some of our rovers or some of our satellites around other planets come back with really interesting data," says Thaller.
- What will our first proof of alien life be like? Most likely microbial, but even those microbes will reveal so much: Does it have DNA? Is it similar to us? Is it different from us? How else can life evolve? These questions—and answers—will change our view of the universe forever.
A young star and a belt of gasses give the game away.
- Scientists have provided the first confirmation that what's at the center of the Milky Way is a supermassive black hole.
- The discovery caught the interaction of gasses and a small star spinning around the mysterious object.
- This is thought to be compelling proof of the black hole's central role in a galaxy.
From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.
- While it's one of the best on Earth, the human brain has a lot of trouble accounting for certain problems.
- We've evolved to think of reality in a very specific way, but there are plenty of paradoxes out there to suggest that reality doesn't work quite the way we think it does.
- Considering these paradoxes is a great way to come to grips with how incomplete our understanding of the universe really is.
Famous physicists like Richard Feynman think 137 holds the answers to the Universe.
- The fine structure constant has mystified scientists since the 1800s.
- The number 1/137 might hold the clues to the Grand Unified Theory.
- Relativity, electromagnetism and quantum mechanics are unified by the number.
