PIX4634142: Evolution of the universe: from the dark age to galaxies - In this diagram, the upper left represents the cosmic Dark Age, when the universe was so hot that atoms could not form and photons could not travel freely. The red area represents the de-ionization era, when the universe became transparent. The Cosmic Background Radiation comes from this time, Dixon, Don (b.1951) / Bridgeman Images
PIX4639479: Permanent station project between Mars and the Earth-Vue d'artiste - Mars Cycler - Artist view - Artist view of the Mars Cycler project, four space stations placed in cylindrical orbit between Mars and the Earth; this project defended by Edwin Aldrin will make it possible to make a permanent link between the two planets. Artist's concept of the Buzz Aldrin Mars Cycler. A Mars cycler is a space station project that is on a permanent orbit between the Mars and Earth, 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
PIX4640370: Artist view of a spacecraft and a comet - A spacecraft approaching a comet - Artist view - Artist view of a spacecraft approaching a comet on Earth. Illustration made for the cover of Gregory Benford's novel “Dans l'ocean de la nuit” (in the ocean of night). A spacecraft approaches a comet that is on a collision course with earth, Dixon, Don (b.1951) / Bridgeman Images
PIX4640540: 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
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
PIX4606083: 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
