PIX4607486: Interstellar nuclear propulsion ship - Artist's view - Starship nuclear pulsed - Artist view - A spaceship declines its nuclear propulsion mode as it passes the hidden face of the Moon. This huge ship is essentially food and fuel reserves could reach the nearest star, Alpha of the Centaur, in less than 50 years. Inspired by the Daedalus project. An interstellar ship ignites its nuclear pulse rocket engine over the farside of the moon. The 10 - kilometer - long vessel consists mostly of fuel and other consumables. After 10 years, it will have achieved 10 percent the speed of light, making possible a voyage to the nearest star, Alpha Centauri, in 50 years, when some of the original voyagers might still be alive, Dixon, Don (b.1951) / Bridgeman Images
PIX4607548: Object of Thorne-Zytkow - Artist's view - Thorne-Zytkow object - Artwork: An object of Thorne-Zytkow is a star shaped like a red supergiant star whose heart is occupied by a neutron star. A Thorne- ytkow object is a conjectured type of star wherein a red giant or supergiant contains a neutron star at its core, formed from the collision of the giant with the neutron star. Such objects were hypothesized by Kip Thorne and Anna ytkow in 1977, Dixon, Don (b.1951) / Bridgeman Images

The Pioneer 10 and Pioneer 11 probes have embarked on a plate, called the Pioneer plate, containing a message intended for potential aliens. The Pioneer 11 probe flys past Satur, Dixon, Don (b.1951) / Bridgeman Images

PIX4583616: Artist view of the fall of a meteorite in Greenland - Fire over ice - Artist view - Artist view of the fall of a meteorite in Greenland. On December 9, 1997, a huge fireball was observed by several witnesses. The impact on Earth was detected by satellite; the object reportedly broke into four pieces before touching the ground.

PIX4573686: Artist's view of the exoplanet Gliese 581c. - Artist's view of the exoplanet Gliese 581c. Gliese 581c, with a radius of 1.5 times that of the Earth, is the first exoplanet gathering the necessary elements to imagine the existence of a possible extra-terrestrial life. With a mass of 5 times that of the Earth, an average temperature between 0 and 40* C, this exoplanet rotates around its star in just thirteen days and is located 14 times closer to its star than the Earth is to the Sun. But this star, Gliese 581, is a red dwarf, a star much smaller and less luminous than the Sun, so the position of this exoplanet is ideal for allowing the presence of water in liquid form on its surface, Dixon, Don (b.1951) / Bridgeman Images
