PIX4613953: Active galaxies in collision - Artist view - Active galaxies collide - Artist view - Artist view of a quasar whose jet is powered by the material of a galaxy rentree in collision. Active galaxies collide, feeding matter to the central black holes that power quasars, Dixon, Don (b.1951) / Bridgeman Images
PIX4607482: Project Daedalus - Vue d'artiste - Daedalus project - Artist view - Daedalus was an interstellar space probe project written in the 1970s. The aim was to make a probe capable of examining the Barnard star system in order to study possible planets. A crewed starship based on the British Interplanetary Society's 1970's Daedalus design fires its nuclear pulse engine in interstellar space. The engine, capable of producing 0.01 gravity acceleration, boosts the ship to 10 percent the speed of light after ten years of thrust, Dixon, Don (b.1951) / Bridgeman Images
PIX4573965: Super Terre et Dwarf Rouge - Red Dwarf on the horizon of a Super - Earth - Illustration showing the surface of an extrasolar terrestrial planet, a super Earth, much older than our planet. In the sky, her star, a red dwarf. The exoplanet, too close to its star, knows extreme temperatures making life impossible. Much older than earth and tidally - locked toward its sun, the planet's surface has been eroded by the fierce winds that howl across the twilight zone between eternal day and night, Dixon, Don (b.1951) / Bridgeman Images
PIX4572453: Artist view of Gliese 710 near the cloud of Oort - Gliese 710 near Oort cloud - Artist view - The star Gliese 710 is a red dwarf of our galaxy, located about 63 years ago - light from the Sun. This star has its own movement and is approaching our solar system that it may reach within 1.4 million years. The cloud of Oort could be disturbed. Comets in our solar system's Oort Cloud are disturbed by the passing of a nearby dwarf star, Gliese 710, in the distant future, Dixon, Don (b.1951) / Bridgeman Images
PIX4572673: Vue d'artiste d'une cepheide - Cepheid - artist view - Vue d'artiste d'une cepheide. Cepheides are very bright variable stars that serve as cosmic beacons to measure the distance of nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. A Cepheid variable star pulses in a regular period that is directly related to its intrinsic brightness, allowing astronomers to use such stars as “” standard candles”” to measure distances to other galaxies, Dixon, Don (b.1951) / Bridgeman Images
PIX4571570: In the cloud of Oort - Illustration - Inside the Oort cloud - Illustration - The cloud of Oort is a vast body envelope located well beyond the orbit of the planets of the solar system. Comets would come from that cloud. The Oort Cloud is a huge spherical cloud surrounding our Solar System. Extending about 30 trillion kilometers (18 trillion miles) from the Sun, it was first proposed in 1950 by Dutch astronomer Jan Oort. The vast distance of the Oort cloud is considered to be the outer edge of the Solar System where the Sun's influence ends. It contains billions of icy bodies and seems to be the birth place of comets, Dixon, Don (b.1951) / Bridgeman Images
PIX4583359: Supernova and Planet - Artist's View - Supernova Explosion - Artist view - A planet devastee by the intense radiation emitted by the explosion of a star. Mountain ranges melt on the outer planet of a star that has gone supernova. Even before the wave of ejecta from the exploding star reaches the planet, the unimaginably intense radiation has turned the world's crust molten, Dixon, Don (b.1951) / Bridgeman Images

Huygens landed on the Titan satellite on 14 January 2005. The Cassini-Huygens probe was launched on 15 October 1997 and has been placed in orbit around Saturn since 1 July 200, Dixon, Don (b.1951) / Bridgeman Images
