How long would it take to terraform a planet?
How long would it take to terraform a planet?
Time/setting: Up to 20,000 years in the future, following optimistic peaceful resolution of current self-destructive stupidity on Earth. Technology: Realistic extrapolations of modern science.
Will terraforming ever be possible?
But in 2020, Mars is very much on the agenda. NASA, SpaceX, Virgin Galactic -- they all want to put space boots on the ground, and in some cases as soon as the 2030s. But as scientists work toward blastoff, the concept of terraforming will most likely be a case of "failure to launch."
Can you fly through Jupiter?
A Solid Core In the distant future, engineers may be able to build a spacecraft that can withstand the conditions inside a gas giant like Jupiter, but even if they do, the craft won't be able to fly straight through the planet.
What would you see if you fell into Jupiter?
This is a lot faster than you'd fall from the top of Earth's atmosphere because Jupiter's gravity is much stronger than Earth's. You'll still be able to see the sun, but don't expect it to heat you up. At about 250 km (155 miles) down you'd reach the ammonia clouds and experience -150 C (-240 F) temperatures.
What keeps Jupiter together?
The gas that composes a gas giant "sticks" to the planet the same way that the atmosphere of earth "sticks" to the earth: Gravity. Even if the planet didn't have a solid core, the gasses themselves have mass. This mass is the source of the gravity for the planet.
What is the orange spot on Jupiter?
Jupiter's Great Red Spot is a gigantic storm that's about twice as wide as Earth, circling the planet in its southern hemisphere. At the storm's center, winds are relatively calm, but on its edges, wind speeds reach 270-425 mph (430-680 km/h).
Why Jupiter is not a rocky planet?
Jupiter is primarily composed of hydrogen, but helium comprises one quarter of its mass and one tenth of its volume. It likely has a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface.
What is a fun fact about Jupiter?
Fun Facts about the Planet Jupiter It is the fastest spinning planet in the Solar System. Jupiter has three very faint rings. It has an extremely strong magnetic field that is 14 times stronger than the magnetic field of the Earth. Viewed from the Earth, it is the third brightest object in the night sky.
What is the wind like on Jupiter?
These wind speeds, equivalent to about 1450 kilometres an hour, are more than twice the maximum storm speeds reached in Jupiter's Great Red Spot and over three times the wind speed measured on Earth's strongest tornadoes.
Does Jupiter have rain?
Somewhere deep inside Jupiter it is raining helium. ... The helium rain, which begins in misty clouds of fine drops that grow larger with depth, fall through this ocean of liquid hydrogen the same way oil refuses to mix with water. A slice of the interior of Jupiter.
Is there snow on Jupiter?
'It's Snowing on Jupiter': Stunning Photos Show Clouds High in Gas Giant's Skies. ... The white clouds, which get up to 50 miles (80 kilometers) wide or so, are high up in Jupiter's atmosphere — so high that they're very cold, and the material they shed is therefore almost certainly frozen, Juno team members said.
Which planet is most like Earth Venus or Mars?
In composition, size, in atmosphere, etc? Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
Can we live on Mars?
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.
