Big "scary" asteroid flying between Earth and Moon tonight, 5/15/18
An asteroid about the size of a New York City block is flying between the Earth and the Moon today. How close, though?
An asteroid about the size of a New York City block is flying between the Earth (you may have heard of it) and the Moon (you may have seen it) at about 6pm EST today. That's "pretty damn close" by aeronautic standards.
The moon is about 252,088 miles (405,696 km) away — so about 30 planet Earth's could fit between here and the moon. The asteroid will pass at almost the exact halfway point between the moon and here, about 126,000 miles away. You won't be able to see it with the naked eye. But a hobbyist telescope, pointed in the right direction at the right time, should be able to see it.
The asteroid that wiped out the dinosaurs was 6 miles wide, so in the grand scheme of things this isn't a world-ending space rock — it's worth reiterating that asteroid happened to hit at the "worst possible" place it could have, as only 13% of the land on Earth could create that much dust which is what ultimately wiped out the dinosaurs by effectively forcing a nuclear winter. But while the asteroid that's zinging past us today is only 900ft long, it's still too close for comfort. Consider this: the meteorite that created the Barringer Crater was only 160ft long and created this:
Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
At least he wasn't burned at the stake, right?
- The letter suggests Galileo censored himself a bit in order to fly more under the radar. It didn't work, though.
- The Royal Society Journal will publish the variants of the letters shortly, and scholars will begin to analyze the results.
- The letter was in obscurity for hundreds of years in Royal Society Library in London.
