Those are just fabulously cringe in all ways.
Best use of tax dollars.
Has someone at the Chinese space agency been watching too much Star Trek...?
Check out the top right corner of the image.
The United Federation of Planets's headquarter will not be in San Fransisco, but in Beijing.
Olympus Mons on Mars, from the ISRO Mars Orbiter.
To put that into perspective...
Weird Star System's Planet-Forming Disk Goes Vertical Like a Ferris Wheel
Still waiting for a Planet or Star to be named ABC12345
Out of curiosity, presumably at some point the Moon will leave our orbit and become just another rock in our solar system, be it's own orbit around the sun or it'll just drift off into the abyss.
What happens to Earth at this point? No more tides? No more Werewolves?
Apparently not. Though the Moon is currently receding, this will stop in about 50 billion years. And in this more “stable” configuration, both the rotation of the Earth and the orbit of the Moon will take 47 days. Meaning: only one side of the Earth will ever see the Moon, and ocean tides will be “frozen” in place.
At least… that’s what could happen theoretically.
Long before then, most life will be dead (due to the cessation of photosynthesis - ~500 million years from now); and the Sun will expand and consume the Earth (~5 billion years from now).
IOW, certain other issues will present themselves before we have to worry about the Moon being too far way.
We've got ~500 million years to colonise and terraform the Moon then?
Thank You for the reply. I had assumed it would just drift off, though instead, it'll have burnt up - along with Earth long before it even attempts it's great escape.
Not the moon, because that'll be consumed with the Earth. Need to get into Mars and beyond.
It is sometimes disturbing to think about (although we'll all be long dead and not have to worry about anyways) how life is in its twilight years on Earth. The vast majority of the history of life on this planet has already happened. Roughly 87-90% is in the rearview mirror.
It's scary, isn't it? To think how much life has preceded humanity, and yet here we are, ultimately still in our infancy. I don't think a lot of people quite comprehend just how long ago the Jurassic, Triassic and Cretaceous (and before) periods actually were.
More bad news for Krypton:
HubbleSite: News - Young Planets Orbiting Red Dwarfs May Lack Ingredients for Life
As part of their natural (and volatile) formation, red dwarf star systems may blast away their supply of water. This means that Earth-sized planets in such systems (even if they’re in the “Goldilocks zone”) could be dry and lifeless.
As it happens, red dwarfs make up about three-quarters of all the stars in the Milky Way. So the hypothetical estimates for extraterrestrial life may have to be drastically reduced.
Carbon based life may be at a disadvantage, but who knows what else is out there.
Watched a little youtube doc about Apollo 13 last night really makes you stand back in awe at the level of ingenuity people have.
And then you watch a video of Trump and begin to question said ingenuity.
Well, sort of. That still makes up A LOT of potential habitable planets out there. The next most common type of star (K Class) is thought to be the most likely to produce life.
For sure, and even the whole Phanerozoic Eon is just a small part of the history of Earth. And it is especially difficult to picture when you start comparing two different points in time. Tyrannosaurus rex was closer in time to US than it was to animals like Stegosaurus and Apatosaurus. The Cretaceous Period on its own was longer than the whole Cenozoic Era so far.
To get some perspective. If Earth's history were a year, then Homo Sapiens would have appeared 23:36 on December 31
Earth’s Calendar Year: 4.5 billion years compressed into 12 months - Biomimicry 3.8
Life appears on the 25th of February. Dinosaurs appear in mid-December. Complex life in any form doesn't appear until Thanksgiving. Human history (as opposed to prehistory) begins about 30 seconds to New Year's. That about says it all really.
This is a variation of the “cosmic calendar” made famous by Carl Sagan. But in that model, the age of the entire Universe - rather than the age of the Earth - is compressed into a calendar year. As such, the dates and times of milestones are shifted slightly (as per the difference between 13.8 and 4.5 billion years).
Overlooked (or simply irrelevant) to so many people. It truly is astonishing when you think about it - and frightening too. In all that time, we're the only (known) species to have developed a sense of sentience in not only life on Earth, but (as we know it) life in the entire universe. Not that I believe we're alone in the universe for one minute, but when you factor things like this in, and the time scale of it, it truly does make you wonder what else is out there, or more specifically, what could have been a long, long time ago - and what may still come.
