nor too far away. Because of this position, Kepler-22b might have water, one of the main things needed for life. The newly-discovered planet is about two and a half times larger than the Earth. It is closer to its star than we are to the Sun, but 22b’s sun is smaller than ours...
a planet about six hundred light years away.It is the first planet in a"habitable zone"outside the solar system.That means the planet orbits a star like our Sun,but it is not too close to it,nor too far away.Because of this position,scientists say Kepler22b might have water,one of ...
In 2011, the planet Kepler-22b was discovered 600 light years from Earth and in the habitable zone of its star. But the reality is that finding life in such remote locations is going to be hugely more difficult than in the cosmic backyard of our solar system....
It turns out that measuring the distance to a star is an interesting problem! Astronomers have come up with two different techniques to estimate how far away any given star is. The first technique uses triangulation (a.k.a. parallax). The Earth's orbit around the sun has a diameter of ...
Simulate lunar free-return trajectory for satellite scenario A lunar free-return trajectory is a transfer trajectory that takes a spacecraft from Earth orbit to the Moon and back without any additional maneuvers. The new example demonstrates how to simulate a lunar free-return in a satellite ...
An artist's concept of Kepler-186f, an Earth-size planet found orbiting in the habitable zone of its parent star. A planet like Kepler-186f with a smaller orbit than Earth's could be at risk of having only one hemisphere face toward the star, with the other hemisphere always facing away...
carried by winds that built up over time until it eventually couldn’t generate enough power to keep operating. Or a spacecraft that’s in orbit might run out of propellant, so it’s no longer able to orient itself and return information to Earth, as happened with theKepler Space ...
Among the exoplanets catalogued so far, a few could match this water world. One such discovery is Kepler-22b. Kepler-22b, at 2.4 times Earth's radius and orbiting within its star's habitable zone, could be a water-covered planet. Credit: NASA...
earth. You may thinksolar poweris futuristic and impractical, but in fact the world has been solar powered ever since it was created. Playing the energy game reveals something else as well: we can never actually create energy or destroy it. Instead, all we can do is convert it from one ...
The researchers were also able to prove that the discrepancy between observational data and model calculations disappears if the star’s magnetic field is included in the computations. To this end, the team turned to selected data from NASA’s Kepler Space Telescope, which captured the light of ...
