PIX4632636: Comets have the origin of life on Earth - Comets bring life on Earth - An artist's view of the Earth bombed by comets 4 billion years ago. Comets may have brought the molecules necessary for the appearance of life on Earth. The Moon at that time was much closer to Earth than today. Impacting comets may have brought life to the early Earth. 4 billion years ago, Moon was closer than today / Bridgeman Images
PIX4632660: Life on Earth: the Sun and Comets - Life on Earth: Sun and Comets - All living organisms on Earth are exclusively left amino acids. The origin of life homochiralite, the asymmetry present in amine acids, could be derived from solar radiation distruding the right amino acids accumulated on comets during the formation of the solar system. Life on Earth is made of left handed amino acids, almost exclusively. The origin of biomolecular homochirality could come from the sun light destroying right handed amino acids in comets during the formation of solar system / Bridgeman Images

PIX4632742: The First Life Forms on Earth - Eoarchean Earth - 3.8 billion years ago, 770 million years after the formation of the Earth, the first life forms appeared as a unicellular organism. Bacteries and archeobacteries (archaea) began to populate the Earth's surface while the atmosphere was still filled with volcanic gases and probably without oxygen. In this illustration, these micro-organisms came out of the ocean to attach themselves to the rock remains of a caldera, bringing colour to this monochrome landscape. 770 million years after the formation of the Earth - - 3.8 billion years ago - - the first life may have appeared in the form of simple, single - celled organisms. Bacteria and archaea may have even found a way to populate the otherwise sterile and inhospitable surface. The atmosphere would likely have consisted solely of gases vented by volcanoes: carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen, methane, hydrogen, methane, ammonia, and water vapor. In this image, a variety of single - celled organisms have ventured out of the ocean and onto the rocky remains of two volcanic calderas, adding color to an otherwise bleak and monochromatic landscape. While the lack of breathable oxygen would be anathema to complex life forms like ourselves, this primitive atmosphere was a rich source of sustenance for these terrestrial vanguards / Bridgeman Images
PIX4632781: Ichthyostega & Rhacophyton - An Ichthyostega emerge water 365 million years ago to the upper Devonian. Half-fish, half-terrestrial animal, the Ichthyostega was about 1 metre long. On the left, one of the first species of fern, Rhacophyton ceratangium. A Late Devonian Ichthyostega emerges from waters of a floodplain 365 million years ago in what is today the Canadian Arctic. On the left is a four - foot - tall Rhacophyton ceratangium, an ancient shrub that is thought to be one of the earliest ferns. On the horizon are more Rhacophyton, along with towering Archaeopteris and Lycopsids in various stages of growth / Bridgeman Images
PIX4632814: Ichthyostega - View of an Ichthyostega 365 million years ago at the upper Devonian. Half-fish, half-terrestrial animal, the Ichthyostega was about 1 metre long. On the left, one of the first species of fern, Rhacophyton ceratangium. In the foreground, prehistoric arthropods (diplopods and cockroaches). A close - up of a three foot long Late Devonian Ichthyostega 365 million years ago in what is today the Canadian Arctic. Flanking the Ichthyostega are Rhacophyton ceratangium, ancient shrubs that are thought to be one of the earliest ferns. The reddish fruit - like nodules attached to the fronds on the right are sporangia, enclosures in which spores are formed. The large tree - like trunk on the far left is the base of a young Archaeopteris. In the foreground are prehistoric arthropods - - a millipede on the left and on the right cockroaches on trunk of a decaying Lycopsid. Arthropods had been walking the Earth for 40 million years before vertebrates like Ichthyostega began venturing ashore. Ichthyostega was one of the earliest tetrapods, a descendent of lobe - finned fishes and ancestor of amphibians. Ichthyostega had lungs and seven - toed limbs that allowed it to move about the shallow waters and shores of swamps and floodplains. It was among the first terrestrial vertebrates / Bridgeman Images

PIX4630291: Planets of the solar system -2006 - Our solar system. 2006 - Planets are represented in order of proximity to the sun. From top to bottom: Mercury, Venus, Earth and Moon, its satellite, Mars, Jupiter, Saturn, Uranus, Neptune. Since August 2006, Pluto is now called 134340 Pluto and is no longer considered a planet but designed as a dwarf planet. This is a montage of planetary images taken by spacecraft managed by the Jet Propulsion Laboratory in Pasadena, CA. Included are (from top to bottom) images of Mercury, Venus, Earth (and Moon), Mars, Jupiter, Saturn, Uranus and Neptune. The spacecraft responsible for these images are as follows: the Mercury image was taken by Mariner 10, the Venus image by Magellan, the Earth and Moon images by Galileo, the Mars image by Mars Global Surveyor, the Jupiter image by Cassini, and the Saturn, Uranus and Neptune images by Voyager. Pluto is not shown as no spacecraft has yet visited it. The inner planets (Mercury, Venus, Earth, Moon, and Mars) are roughly to scale to each other; the outer planets (Jupiter, Saturn, Uranus, and Neptune) are roughly to scale to each other / Bridgeman Images
PIX4630295: The formation of the Solar System - Artist view - Forming solar system - Artist view - Artist view of the gas and dust disc (protoplanetary disc) around the Sun.

PIX4630355: La formation du système solaire - Vue d'artiste - Artist's impression of the development of the Solar System - Vue d'artiste de planete en formation dans le disque de gaz et de dusts (disque protoplanetaire) autour de son toile. This artist's impression shows four stages of the development of the inner Solar System over a period of almost five billion years. The top panel shows the earliest stage where the debris disc around the Sun was composed of gas and tiny particles, typically less than one millimetre across. At the second stage the particles have formed large clumps, roughly 100 kilometers across and, similar to the asteroid Lutetia. These bodies in turn formed the rocky planets including the Earth, shown in the third panel down. Over the subsequent four billion years the surface of the Earth developed to what we know now under the influence of meteor bombardment that delivered volatile materials including water, and the evolution of life on its surface / Bridgeman Images

PIX4632872: Carboniferous fauna and flora - Calamites & Meganeura - Meganeura, giant dragonflies whose wingspan could exceed 80 cm, fly among calamites and asterophyllites. Giant Meganeura, resembling and related to present - day dragonflies, flutter between Calamites and Asterophyllites in a Carboniferous scene from over 300 million years ago. Now extinct, Calamites and Asterophyllites are related to today's horsetails, though they grew much larger. The Calamites resembled modern “” Christmas tree”” conifers, while the Asterophyllites looked somewhat like modern Thuja (arborvitae) / Bridgeman Images
