Water Found On A Habitable Alien Planet, NASA Future Interstellar Ship Can Get There In 52 Weeks

Astronomers have finally disclosed the discovery of water vapor in the atmosphere of a super-Earth exoplanet orbiting within the habitable zone of its star. The find means that liquid water could also exist on the rocky world's surface, potentially even forming a global ocean.

The system also contains another exoplanet sitting closer to the star, but it lies inside of the star's habitable zone. Right: NASA 3D model of an interstellar ship powered by warp drive.
The discovery, made with NASA's Hubble Space Telescope, serves as the first detection of water vapor in the atmosphere of such a planet. And because the planet, dubbed K2-18 b, likely sports a temperature similar to Earth, the newfound water vapor makes the world one of the most promising candidates for follow-up studies with next-generation space telescopes.

"This is the only planet right now that we know outside the solar system that has the correct temperature to support water, it has an atmosphere, and it has water in it, making this planet the best candidate for habitability that we know right now," lead author Angelos Tsiaras, an astronomer at University College London, said in a press conference.

Planet K2-18 b sits some 110 light-years away in the constellation Leo, and it orbits a rather small red dwarf star that's roughly one-third the mass of our own Sun. Red dwarfs are infamous for being active stars that emit powerful flares, but the researchers point out that this particular star appears to be surprisingly docile.

This bodes well for the water-bearing planet, as its 33-day orbit brings it about twice as close to its star as Mercury is to the Sun. "Given that the star is much cooler than the Sun, in the end, the planet is receiving similar radiation to the Earth," said Tsiaras. "And based on calculations, the temperature of the planet is also similar to the temperature of the Earth."


Specifically, the paper suggests K2-18 b has a temperature between about –100 °F (–73 °C) and 116 °F (47 °C). For reference, temperatures on Earth can span from below –120 °F (–84 °C) in regions like Antarctica to above 120 °F (49 °C) in regions like Africa, Australia, and the Southwestern United States.

Although K2-18 b flaunts some of the most Earth-like features observed in an exoplanet so far — water, habitable temperatures, and a rocky surface — the researchers point out the world is still far from Earth-like. First off, K2-18 b is roughly twice the diameter of Earth, which makes it about eight times as massive. This puts K2-18 b near the upper limit of what we call a super-Earth — which typically refers to planets between about one and 10 Earth masses.

But the density of K2-18 b is what really cements it as a rocky planet. With a density about twice that of Neptune, K2-18 b has a composition most similar to Mars or the Moon. So, because the planet is believed to have a solid surface, and it's known to have an extended atmosphere with at least some water vapor, researchers say it's feasible that K2-18 b could actually be a water world with a global ocean covering its entire surface.

Dr. Harold "Sonny" White is still working on a warp drive at NASA's Johnson Space Center. Dr. Harold White's work at the Advanced Propulsion Theme Lead for the NASA Engineering Directorate.

Concept 3D artist Mark Rademaker told io9 that "he worked with White to create the updated model, which includes a sleek ship nestled at the center of two enormous rings, which create the warp bubble."

Dr. White—whose daily life is working in future propulsion solutions for interplanetary travel in the near future, like ion and plasma thrusters—developed new theoretical work that solved the problems of the Alcubierre Drive concept, a theory that allowed faster-than-light travel based on Einstein's field equations in general relativity, developed by theoretical physicist Miguel Alcubierre.

A spaceship equipped with a warp drive would allow faster-than-light travel by bending the space around it, making distances shorter. At the local level, however, the spaceship wouldn't be moving faster than light. Therefore, warp drive travel doesn't violate the first Einstein commandment: Thou shall not travel faster than light.

You can watch the fascinating talk that Dr. White gave at the SpaceVision 2013 conference here:



If his work is successful, he says that we would be able to create an engine that will get us to Alpha Centauri which is 4.3 light years away "in two weeks as measured by clocks here on Earth." The time will be the same in the spaceship and on Earth, he claims, and there will not be "tidal forces inside the bubble, no undue issues, and the proper acceleration is zero.

Planet K2-18 b is 110 light-years away which means it will take spaceship approx 52 weeks to get there.
