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
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
PIX4572699: Artist's view of an eruptive star - Flare star. Artwork - An eruptive star is a variable star that can manifest a dramatic and imforeseeable increase in luminosite from a few minutes to a few hours. From X-rays to radios, the spectrum increases in intensity. Eruptive stars are red dwarves, although recent research indicates that brown dwarves may also be capable of eruptions. A flare star is a variable star which can undergo unpredictable dramatic increases in brightness for a few minutes or a few hours. The brightness increase is across the spectrum, from X - rays to radio waves. Flare stars are dim red dwarfs, although recent research indicates that brown dwarfs might also be capable of flaring, Dixon, Don (b.1951) / Bridgeman Images
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
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
