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
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
PIX4584082: Collision de deux asteroides- Vue d'artiste - Asteroid collision - Artist view - A large asteroid is struck by a smaller one. Since both bodies are porous, most of the energy is absorbed as heat, rather than dispersed with ejecta, thus explaining the internal melting of asteroids, Dixon, Don (b.1951) / Bridgeman Images
PIX4584542: Black hole in the center of the galaxy - Artist view - Black hole in the galaxy's center - Artist view - Artist view from the black hole in the center of the galaxy. Clouds of gas and dust swirl into the black hole at the core of the Milky Way galaxy, Dixon, Don (b.1951) / Bridgeman Images
PIX4634481: The first galaxies - The first galaxies - Artist's view of the appearance of giant stars at the intersection of hydrogen filaments, which will form the nuclei of the first galaxies. Giant stars form at the intersections of great filaments of primordial hydrogen, forming the nuclei of the first galaxies, Dixon, Don (b.1951) / Bridgeman Images
