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
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
PIX4634248: The Universe in a Hand - Artist's View - Universe in Hand: Artist's view representing the universe measuring only 10 centimetres in diameter before inflation. 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
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
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
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
PIX4623968: Neptune and its rings - Illustration - Neptune and its rings - Illustration - Neptune has a system of several rings; the farthest from Neptune is called Adams and contains the bows Liberte, Egalite, Fraternity and Courage. In this artist's view, the small satellites of Neptune are also represented; from the closest to the farthest from the planet, we find: Naiade, Thalassa, Despina, Galatee, Larissa and Protee, Dixon, Don (b.1951) / Bridgeman Images
PIX4626297: Saturn seen from his satellite Japet - Saturn as seen from Iapetus - Artist's view of the surface of the satellite Japet and the planet Saturn eclipsing the Sun. Saturn as seen from Iapetus Saturn produces a “” diamond ring”” effect as it eclipses the sun in this perspective from the satellite Iapetus. Artist view, Dixon, Don (b.1951) / Bridgeman Images
