NASA has designed beautiful posters detailing what life could be like outside our solar system.
NASA’s Kepler Space Observatory hasn’t yet found true alien life, but it has identified several extrasolar planets, or Exoplanets. To mark the exciting discovery of a potentially distant habitable exoplanets by Kepler telescope, NASA’s Jet Propulsion Laboratory has created a series of posters advertising imaginary vacations to some of them. The Jet Propulsion Laboratory, which is at the California Institute of Technology, has designed three ‘Exoplanet Travel Bureau’ posters. The posters are done in vintage format and belong to three exoplanets, which are similar to Earth.
David Delgado, one of the designers of the posters, said, “There was a lot of back-and-forth with the scientists, figuring out which exoplanets to choose, then noodling on what it would actually be like to visit them.”
One of the poster that was named ‘Experience the Gravity of a Super Earth’, features the exoplanet HD 403057g . That exoplanets is twice the size of Earth and has eight times its mass. It also has a gravitational punch that is much stronger than Earth’s.
Second poster, which is called ‘Where the Grass is always Redder on the Other Side’ shows life on Kepler-186f. It was the first Earth-size planet found in the potentially ‘habitable zone’ of another star. Astronomers believe that liquid water might exist on the planet’s surface. However, its star is much cooler and redder than our sun. This would make the plant life on that exoplanet very different from the ones found on Earth and they definitely won’t be green.
The third poster was ‘Where your shadow always has a company’, which was about the exoplanet Kepler-16b. This exoplanet orbits a gravitationally bound pair of stars. That would make any object on the exoplanet’s surface cast two shadows.
NASA has added that people who are interested in the posters can download them in high-resolution print from The Jet Propulsion Laboratory’s site.
