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
PIX4574971: Jupiter's Rings and Satellites - Illustration - Jupiter's Rings and Satellites - Illustration - Jupiter is surrounded by a system of very dark rings composed of dust removed from some of its satellites. This system consists of a main ring, located between the Metis and Adrastee satellites, then rings very held on the orbits of the Amalthee and Thebe satellites., 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
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
