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
PIX4571550: A laser shot attempts to deflect a comet nucleus - Illustration - High - powered laser to deflect a comet nucleus - Illustration - A powerful laser pulls from Earth's orbit, tries to deflect a threatening comet. A high - powered laser in earth orbit blasts surface material from an approaching comet nucleus in an effort to deflect it, Dixon, Don (b.1951) / Bridgeman Images
PIX4633495: The Moon barely formed seen from the Earth - Illustration - The Moon barely formed seen from the Earth - Illustration - The Moon would be born from the impact of a big asteroid on Earth. The material ejected during this collision would have combined to form the Earth's satellite. This artist's view shows the Moon seen from Earth with a ring of ejectees in its orbit, Dixon, Don (b.1951) / Bridgeman Images

The universe is shown when it was only 10 centimeters in diameter, 10 ^ -32 seconds after the Big Bang., Dixon, Don (b.1951) / Bridgeman Images
PIX4630295: The formation of the Solar System - Artist view - Forming solar system - Artist view - Artist view of the gas and dust disc (protoplanetary disc) around the Sun. Little by little rocks will gather, accrete, to form planets. Planetesimals - the seeds of planets crash together in the solar nebula, gradually growing larger, Dixon, Don (b.1951) / Bridgeman Images
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
PIX4605677: Pioneer 11 and Saturn - Artist's View - Pioneer 11 Saturn flyby - Artist view - Pioneer 11 was launched on April 5, 1973 with as its first destination the planet Jupiter, which it flew over in December 1974; it was the first probe to fly over Saturn in September 1979. 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.
