Exoplanet Travel Series – NASA spielt Reisebüro in dreiteiliger Poster-Serie

Die NASA als Reisebüro. Das Angebot umfasst (momentan) drei Poster mit Exoplaneten, die ihr euch in HighRes runterladen könnt. Ich schwanke zwischen Kepler-186f und Kepler-16b – vielleicht hänge ich mir aber auch alle drei auf.

Relax on Kepler-16b – Where your shadow always has company

Like Luke Skywalker’s planet „Tatooine“ in Star Wars, Kepler-16b orbits a pair of stars. Depicted here as a terrestrial planet, Kepler-16b might also be a gas giant like Saturn.

Where the Grass is Always Redder on the Other Side

Kepler-186f is the first Earth-size planet discovered in the potentially ‚habitable zone‘ around another star, where liquid water could exist on the planet’s surface. Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star’s red-wavelength photons, making for a color palette that’s very different than the greens on Earth. This discovery was made by Kepler, NASA’s planet hunting telescope.

Experience the Gravity of a Super Earth

Twice as big in volume as the Earth, HD 40307g straddles the line between „Super-Earth“ and „mini-Neptune“ and scientists aren’t sure if it has a rocky surface or one that’s buried beneath thick layers of gas and ice. One thing is certain though: at eight time the Earth’s mass, its gravitational pull is much, much stronger.
