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
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
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
PIX4606088: Huygens probe lands on Titan. - Huygens probe lands on Titan. - Artist's view of the descent of the European probe Huygens on Titan. 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
PIX4640543: Interstellar ship - Artist's view - starship arrives alpha centauri - An interstellar ship arrives in orbit around an exoplanet, after a 50-year journey to the Alpha star of the Centaurus. The bright star under the exoplanet is our Sun, a distance of 4.3 years of light. A habitat two miles across arrives to orbit a hypothetical earthlike planet orbiting the star Alpha Centauri after a 50 - year voyage. The discarded braking stage of the giant starship drifts in the far background. The bright star below the planet is our sun, 4.3 light years away, Dixon, Don (b.1951) / Bridgeman Images

PIX4645711: Satellite HDST and Starshade - High Definition Space Telescope with starshade: High Definition Space Telescope (HDST) is an observation satellite project. Located at the point of Lagrange 2, this satellite equipped with a 12-metre mirror would offer images of the universe 24 times more accurate than those obtained by the Hubble space telescope. It could be accompanied by a blackout (starshade), places in space a long distance from it to block the light of a star in order to observe its exoplanets. The High Definition Space Telescope is almost twice the size of a tennis court. By using a football-field-sized shade to block the light from distant stars, the HDST could directly observe exoplanets;, Dixon, Don (b.1951) / Bridgeman Images
PIX4593076: The stars of the constellation Orion 3D views - Stars in the constellation Orion 3D representation - The stars of the constellation Orion seen in 3 dimensions. The stars delineating the constellation Orion are dispersed across nearly 2,000 light years in this 3D representation, Dixon, Don (b.1951) / Bridgeman Images
PIX4575244: Eclipse seen from Io - Illustration - Eclipse from Io. Artwork - 1975 illustration showing Jupiter eclipsing the Sun from his satellite Io. Frosts that precipitate on IO's surface while in Jupiter's shadow sublime back into the gaseous state, dated concept, Dixon, Don (b.1951) / Bridgeman Images
PIX4646146: Satellite WMAP - Illustration - Satellite WMAP - Illustration - View of satellite WMAP (Wilkinson Microwave Anisotropy Probe), launched on 30 June 2001 and placed in an orbit located at the second point of Lagrange (L2) about 1.6 million km from Earth. This satellite measured temperature fluctuations in the fossil radiation of the primordial universe, Dixon, Don (b.1951) / Bridgeman Images
