PIX4583616: Artist view of the fall of a meteorite in Greenland - Fire over ice - Artist view - Artist view of the fall of a meteorite in Greenland. On December 9, 1997, a huge fireball was observed by several witnesses. The impact on Earth was detected by satellite; the object reportedly broke into four pieces before touching the ground.

PIX4572829: Artist view of a magnetar - Magnetar - Artist view - Artist view of an eruption of X-rays and gamma from a magnetar, a neutron star endowed with a powerful magnetic field. Artist's concept of a burst of X - rays and gamma released by a magnetar, a neutron star with an extremely powerful magnetic field, Dixon, Don (b.1951) / Bridgeman Images
PIX4583634: Artist view of the fall of a meteorite in Saudi Arabia - Saudi Meteor - Artist view - Artist view of the fall of a meteorite in Saudi Arabia. In the middle of the 19th century, a mass of iron would have been seen falling from the sky... Visualization of a meteor impact in the empty quarter of the Saudi Desert in the 19th century, Dixon, Don (b.1951) / Bridgeman Images
PIX4640148: Space elevator - Artist view - Space elevator - Artist view - Elevator project connects to a space station in geostationary orbit. An elevator made of unimaginably strong materials rises 22,000 miles above the equator, providing easy access to space, 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
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
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
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
