PIX4614822: Moon: Formation of the Seas - Ancient Moon Formation of the mare: For millions of years lava flows covered the surface of the Moon. These lava plains are today's lunar seas - Millions of years of giant lava flows, created as asteroids puncture the lunar crust, result in the flat lava plains we see today as the lunar mare, Miller, Ron (b.1947) / Bridgeman Images
FLO4612630: Lesser pettychaps, hippolay motacilla. Handcoloured copperplate drawn and engraved by Edward Donovan from his own “Natural History of British Birds,” London, 1794-1819. Edward Donovan (1768-1837) was an Anglo-Irish amateur zoologist, writer, artist and engraver. He wrote and illustrated a series of volumes on birds, fish, shells and insects, opened his own museum of natural history in London, but later he fell on hard times and died penniless., Donovan, Edward (1768-1837) / Bridgeman Images

PIX4612662: Spiral galaxy M101 in the Great Bear - Spiral galaxy M101 in Ursa Major - The galaxy M101 (NGC 5457) is located about 27 million years away from Earth. Image obtained with a 40 cm telescope, composite of several images, 2h30 pose. M101 (NGC 5457) is about 27 Mly away. Composite image obtained with a RC 16”” telescope / Bridgeman Images
PIX4612686: Spiral galaxy M101 in the Great Bear - Spiral galaxy M101 in Ursa Major - The galaxy M101 (NGC 5457) is located about 27 million years away from Earth. It spans more than 170,000 light years, almost double the size of our galaxy. We think that of the trillion stars in it, 100 billion stars could be similar to our Sun. Composite image obtained from 51 different clicks made by the Hubble space telescope from March 1994 to January 2003 and from ground photos at Kitt Peak and CFHT in Hawaii. Spiral galaxy M101 is a beautiful, large, face - on spiral galaxy located about 27 million light - years away in the constellation Ursa Major. This galaxy's portrait is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground - based photos. The giant spiral disk of stars, dust, and gas is 170,000 light - years across or almost twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. Approximately 100 billion of these stars could be like our Sun in terms of temperature and lifetime. The galaxy's spiral arms are sprinkled with large regions of star - forming nebulae. These nebulae are areas of intense star formation within giant molecular hydrogen clouds. Brilliant young clusters of hot, blue, newborn stars trace out the spiral arms. The disk of M101 is so thin that Hubble easily sees many more distant galaxies lying behind the galaxy / Bridgeman Images

PIX4616893: Mars with water - Artist's view - Martian Waterfall - Artwork: More than three billion years ago, water flowed on Mars. The water is now evaporated. This illustration can also illustrate the terraformation of Mars - 3.5 billion years ago Mars had water. This artwork could also show terraforming of a future March, Miller, Ron (b.1947) / Bridgeman Images
