PIX4577406: Earth and Moon - Apollo 8 - Dec. 1968 - Earthrise from Apollo 8 spacecraft - Earthrise seen from the control module of Apollo 8 on 22/12/1968. This view of the rising Earth greeted the Apollo 8 astronauts as they came from behind the Moon after the lunar orbit insertion burn. Earth is about five degrees above the horizon in the photo. The unnamed surface features in the foreground are near the eastern limb of the Moon as viewed from Earth. The lunar horizon is approximately 780 kilometers from the spacecraft. Width of the photographed area at the horizon is about 175 kilometers. December 22 1968 / Bridgeman Images

PIX4632784: Ichthyostega - Devonian tetrapods - View of atist depicting two Ichthyostega, tetrapods, 385 million years ago, to the upper Devonian. Half-fish, half-terrestrial animal, the Ichthyostega was about 1 metre long. Between them are represented in the water several trilobites and in the background a Bothriolepis. The vegetation consists mainly of ferns and archaeopteris, considered the first trees. A pair of four - limbed, Upper Devonian vertebrate animals of the genus Ichthyostega confront one another 365 million years ago at the edge of a freshwater pond. Basically half fish, half land animal, these tetrapods are each about three feet long. Between them in the water are several marine arthropods known as trilobites. Further beyond in the water is a 12 inch long Bothriolepis. Most of the plant life is varieties of fern, including the tall trees known as Archaeopteris / Bridgeman Images
PIX4662900: Psittacosaurus and pond - The psittacosaur (Psittacosaurus) is a ceratopsian dinosaur from the early Cretace that lived in Asia about 130 to 100 million years ago. A Jurassic Psittacosaurus prepares to dine on a scrubland cycad 130 million years ago in what is today central Asia. Psittacosaurus was one of the earliest known ceratopsians, a family of horned, frilled dinosaurs that includes the better known Triceratops. Psittacosaurus was about 3 to 6 feet long and weighed 50 to 175 pounds, depending on species. At least one species had long, quill-like structures on its tail and lower back. With a parrot-like beak it is believed that Psittacosaurus was a plant-eater / Bridgeman Images
PIX4633209: 100m ocean level rise - Europe - Europe with sea level+100m - Artist's view showing Europe as it would appear if the ocean level increased by 100 metres. This would happen if all glaciers on Earth melt. This is how Europe, North Africa and the Middle East may appear with mean sea level about 100 meters (330 feet) above today's. Such a dramatic rise in sea level could occur if all of the Earth's glaciers were to melt.In this image almost every European country has been flooded with sea water to some extent. Much of the United Kingdom and France have become part of the Atlantic Ocean while Denmark and The Netherlands are completely submerged as are Estonia, Latvia, and Lithuania. The Black Sea has grown to include much of Bulgaria and Ukraine.The Mediterranean Sea now covers parts of Egypt (including all of the Nile delta), Libya and Tunisia and all of western Israel. The Persian Gulf has completely submerged Kuwait, Bahrain, Qatar, and much of Iraq and United Arab Emirates. To the west some of Mauritania and all of Senegal have become part of the Atlantic Ocean / Bridgeman Images

PIX4643170: Galileo satellites - Artist view - Galileo Satellites - Artist view - Artist view of four Galileo In - Orbit Validation (IOV) satellites intended to validate the Galileo positioning system. The Galileo network of European satellites will consist of 30 satellites at approximately 24,000 km of altitude (27 operationals, 3 reserve). Artist view of the four Galileo In - Orbit Validation satellites. The operational Galileo system will consist of 30 satellites (27 operational+3 active spares), deployed in circular Medium Earth Orbit (MEO) at an altitude of 23,616 km altitude / Bridgeman Images

The satellite was launched on 8 May 1985 and its mission ended in 1988. English satellite Telecom - 1B was launched on May 8 1985 and its mission ended in 1988 / Bridgeman Images
PIX4607171: The Rosetta spacecraft releases a lander onto a comet nucleus - The Rosetta spacecraft releases a lander onto a comet nucleus - The Rosetta probe was launched on 2 March 2004 to study comet 67P/Churyumov - Gerasimenko. Artist's view of the Philae probe and lander near the nucleus of the comet. The size scales are not respected, the probe measures 32 meters with its panels deployed, the core of the comet about 4 km. Artist's impression of the Rosetta orbiter deploying the Philae lander to comet 67P/Churyumov - Gerasimenko. The image is not to scale; the Rosetta spacecraft measures 32 m across including the solar arrays, while the comet nucleus is thought to be about 4 km wide / Bridgeman Images
PIX4661625: Pteraspis Backlight - View of Pteraspis artist swimming in the sea 410 million years ago. Two jawless fish of the genus Pteraspis feed near the ocean's surface 410 million years ago during the Early Devonian. Pteraspis grew to a length of about 8 inches and is believed to have dined on shoals of plankton. A hard shell and spikes may have helped protect Pteraspis from larger predators / Bridgeman Images
