Placed on Earth, it would stretch from Washington DC to New York to Detroit. Larger than the Grand Canyon, wider and deeper than East Africa’s Great Rift Valley, Mercury’s newly-discovered “Great Valley” boggles the imagination. But it’s more than size that makes this geologic feature remarkable. The Great Valley may be our best evidence that Mercury’s entire crust is contracting.
This is a nice vid but there are two things to note.
1. he does not mention Callisto in place of Europa. Europa gets enough radiation to kill you in a day where on Callisto you would not even get the radiation you get here on Earth.
2. It might be possible to puff up a given asteroid by creating a cylinder within as he points out, but filling it with water and then heating it from outside and once it’s molten the water will expand and blow the asteroid to a larger size. It may be possible to turn a 1 mile wide asteroid into a ten mile wide habitat. I do not know how well it scales up to larger asteroids.
This episode continues our team up with Fraser Cain to look at Colonizing the Solar System, we move from the inner solar system to the Asteroid Belt and beyond, all the way out to the Oort Cloud.
Part 1: The Inner Solar System, can be watched here:
“Finding the first planet like Earth beyond our solar system would transform how we think about our place in the universe.”
This could cause earthquakes because of the moons mass pulls of the mass of our planet.
There’s a rare supermoon coming this weekend, and no matter how devastated or thrilled you are by the latest election results, you don’t want to miss it.
In the wee hours of Sunday night and Monday morning, the moon will come closer to the Earth than it has in nearly 70 years.
Everyone from astronomers to tech companies wants to know what it would be like to live on Mars.
From growing vegetables in Martian soil, to claims that leaving Earth could save the human species, scientists are constantly making advances in this field.
Now, astronomers from the Royal Observatory in London and Stephen Petranek — author of “How We’ll Live on Mars” — have designed a Martian Show Home to demonstrate what life could be like on the Red Planet.
If you were to compare yourself to a neutron star, you probably wouldn’t find very many things in common. After all, neutron stars – celestial bodies with super strong magnetic fields – are made from collapsed star cores, lie light-years away from Earth, and don’t even watch Netflix.
But, according to new research, we share at least one similarity: the geometry of the matter that makes us.
Researchers have found that the ‘crust’ (or outer layers) of a neutron star has the same shape as our cellular membranes. This could mean that, despite being fundamentally different, both humans and neutron stars are constrained by the same geometry.
In Brief:
To measure the level of a civilization’s advancement, the Kardashev scale focuses on the amount of energy that a civilization is able to harness. Obviously, the amount of power available to a civilization is linked to how widespread the civilization is (you can’t harness the power of a star if you are confined to your home planet, and you certainly can’t harness the power of a galaxy if you can’t even get out of your solar system).
Here’s something to think about — physicists have proposed that the Universe could have a ‘self destruct’ mechanism, whereby everything in existence could disappear forever at any time, without warning.
Yep, as the video by Kurzgesagt — In a Nutshell above explains, if this self-destruct button turns out to be a real thing, it means we could be here one second, and gone the next, and we’d never even see it coming.
To understand this horrifying scenario, we first have to go through two of the fundamental principles of the Universe, the first being energy levels.
Everyone’s talking about private industry getting humans on Mars. Mars trips! Mars houses! Mars colonies! But no one’s going anywhere without the help of one brilliant, peculiar, fantastical space center—NASA’s Jet Propulsion Lab, which is behind almost every amazing feat in the history of space travel. August 2012.
At 2:00 a.m. in the blond hills of La Cañada Flintridge, California, one house stands lit among the others—an open eye in a sleeping town. Bryn Oh, the woman who lives in the house, helps her son Devyn, eight, walk his bike to the parking lot of the high school across the street. Devyn, who just learned to ride, wobbles for a few minutes before pedaling furiously out into the darkness, letting off a whoop as he gets going. Bryn’s older children, Ashlyn, ten, and Braden, thirteen, watch as he goes. David Oh, Bryn’s husband and the reason they’re all up at this uncivilized hour, isn’t there to see it. He’ll arrive home around 3:00 a.m., when he gets off work. Tomorrow will probably be closer to 3:40. Bryn has it all worked out on a spreadsheet.
