Torosaurus - Torosaurs were herbivorous dinosaurs of the cretace, of the same family as the triceratops. Here, a five-ton male is drinking a river. A five ton, 25 foot long male Torosaurus drinks from a river bordered by ferns and Bald Cypress in what is today southeastern Wyoming. Torosaurus was a plant-eating dinosaur from the same family as the better known Triceratops. Torosaurus had one of the largest skulls of any known land animal, reaching over 8 feet in length

Zuniceratops and White Rhinoceros - Comparison - Zuniceratops & White Rhinoceros compared - An adult Zuniceratops who lived 90 million years ago is compared to today's adult white rhinoceros (Ceratotherium simum). The Zuniceratops was 90 centimetres high at the withers and weighed 110 kilograms, while the white rhinoceros was 1.8 metres high at the withers and weighed 3.2 tons. An adult Zuniceratops from 90 million years ago is compared to a modern adult White Rhinoceros (Ceratotherium simum). The Zuniceratops is 3 feet tall at the shoulder and weighs 250 pounds*, while the White Rhinoceros is 6 feet tall at the shoulder and weighs 7,000 pounds.* Values are estimates only based upon available paleontological data

Sunrise seen from Triton - Artist view - Sunrise on Triton - Artist view - Sunrise seen from Triton, the largest satellite in Neptune. A diminutive sun rises over Triton's hard and glistening landscape of rock, frozen water, carbon dioxide, nitrogen, and methane. The little warmth that reaches Triton's surface induces a nitrogen and methane haze, forming a very tenuous atmosphere. It is very cold on Triton with temperatures falling as low as minus 391o F. While as much as 25% of Triton may be composed of water ice, it is very unlikely that there is any liquid water, or life, on this world

Saturn view of the surroundings of Dione - Illustration - Saturn from the vicinity of Dione - The planet Saturn seen from the surroundings of its satellite Dione. Dione, visible in the foreground, has a diameter of about 1100 km and is mainly composed of ice. In the background, another Saturn ice satellite is visible, Tethys. This is how Saturn might appear from near Dione, one of Saturn's inner icy satellites. Dione is about 700 miles in diameter and is believed to be composed primarily of water ice along with lesser amounts of silicate rocks. In this image, Dione is in the foreground orbiting about 197 thousand miles above Saturn's cloud tops. Further towards Saturn at a distance of 50 thousand miles from Dione is Tethys, another icy moon, slightly smaller than Dione. Tethys is silhouetted against the “” ring shine”” on Saturn's night side - - reflected sunlight on the cloud tops from Saturn's rings

Saturn - Illustration - Saturn - Illustration - Artist's view of the planet Saturn. The ring system is composed from the closest to Saturn to the furthest by ring D, then C, B, the division of Cassini, A with the division of Encke, F, G and E. The brightest part of the rings is ring B.

Lightning on Titan - Illustration - Lightning on Titan - Lightning lights illuminate the sky of Titan, Saturn's satellite while astronauts are sheltered in their spaceship. A brilliant flash of titanian lightning illuminates towering clouds of methane while human visitors retire to the safety and warmth of their landing craft. In January 2005, the European Space Agency's Huygens probe detected what may have been electrical discharges due to lightning when it descended through Titan's deep atmosphere (the probe also carried a microphone in hopes of recording the sound of thunder, however none was heard). While Titan's atmosphere may indeed host thunder and lightning, there's been no indication (yet) that there are earthlike cumulous clouds like the ones depicted here

In October 2004 the Cassini orbiter revealed for the first time what may be highly reflective (in the infrared at least) methane clouds over Titan's south pole. This image suggests how those clouds may appear from within the cloud deck itself. The Sun is visible immediately above, though from this great distance the Sun appears to be only 1/10th its diameter from Earth

Titan Exploration - Illustration - Titan's low surface gravity - Astronauts on the surface of Titan. On Saturn's satellite, gravity is lower than on the Moon, an astronaut weights ten times less than on Earth. While Titan is one of the largest terrestrial worlds in the Solar System, larger even than any of the known dwarf planets, the pull of gravity at its surface is only 1/10th the Earth's. Titan's surface gravity is lower than even the Moon's (which is 1/6th the Earth's), and yet Titan's diameter is about 50% larger than the Moon's.

India 70 million years ago - Artist's view - Late Cretaceous India - India seen in the upper cretace about 70 million years ago. The north is upstairs. To the west, Madagascar separates from India. This is how the Indian subcontinent may have appeared 70 million years ago during the Late Cretaceous period. Looking north, immediately to India's west is the island continent of Madagascar and further west is the eastern coast of southern Africa. In the distant past India and Madagascar formed a single continent, however India was part of a separate tectonic plate that subsequently began to drift northward. This northward motion (covering about 8 inches per year making it among the fastest on the Earth's lithosphere) split India from Madagascar and carried it north across the Tethys Ocean until it collided with Eurasia about 50 to 35 million years ago. This collision between the Indian and Eurasian plates joined India to South Asia and created the Tibetan Plateau and the Himalaya Mountains

This is how the western hemisphere of the Earth may have appeared 90 million years ago during the Late Cretaceous period. During this period continental drift, driven by the massive forces of plate tectonics, had broken the supercontinent of Pangea into Laurasia in the north and Gondwana in the south. With a climate much warmer than today's there were no frozen polar caps and the resulting high ocean levels submerged a third of today's landmasses under warm shallow seas creating numerous waterways and “” island””” continents. In this image much of the incipient North American continent is divided by the Western Interior Seaway, the Isthmus of Panama is submerged by the Proto - Caribbean Sea, and the Pacific Ocean is making an incursion into South America

A 30-foot-long, 10 ton juvenile titanosaurian sauropod dinosaur of the genus Antarctosaurus is approached from behind by a 25-foot-long, two ton adult abelisaurid theropod dinosaur of the genus Abelisaurus deep in a forest in what is today Argentina. Likely a fierce predator, Abelisaurus resembled the larger Tyrannosaurus Rex that was to roam North America 10 million years later. Antarctosaurus was an herbivore that may have grown to 60 feet long and weighed up to 100 tons. Antarctosaurus had a squarish, blunt head with peg-shaped teeth

Purgatorius and Bistahieversor - The Bistahieversor is a carnivorous dinosaur living in New Mexico at the end of the cretace 75 million years ago. It was about 9 metres long and weighed at least one ton. In the foreground, a Purgatorius tries to hide himself. A rat-sized Purgatorius hides among the undergrowth of a cretaceous forest while a 30 foot long, 2,000 pound tyrannosaur boreages for its next meal in what is today the western United States. Bistahieversor is a genus of tyrannosauroid dinosaur named after Bisti/De-Na-Zin Wilderness where it was found. Purgatorius is the genus for several species of small omnivorous mammals that are believed to be the among the earliest ancestors of modern-day chimps, rhesus monkeys, and humans. The extinction of the larger and more powerful dinosaurs may have been what led to world's domination by mammals today.

A distant relative of the crocodile, and somewhat larger than modern saltwater crocodiles, Kaprosuchus is notable for boar-like tusks that that project above and below its skull (lending it the nickname BoarCroc). With legs longer than modern crocodiles', Kaprosuchus may have roamed Africa's plains in search of prey which likely included dinosaurs. Baobabs, trees of the genus Adansonia from the mallow family, are large, drought-resistant trees with very thick trunks (a much as 40 feet in diameter) and growing as tall as 100 feet.

A protective shield against predators is a possibility, but relatively fragile, it is likely that it was used as an attribute of visual intimidation to rivals or to attract opposing sex. Although no pigment of colour has been preserved in the fossil remains, it is not unreasonable to imagine that these collars may have been very coloured. A colorful Torosaurus wonders a Cretaceous forest 75 million years ago in what is today southeastern Wyoming. Like the better known Triceratops, Torosaurus was a ceratopsid, a family of large four-legged plant-eating dinosaurs characterized by beaks, rows of shearing teeth in the back of the jaw, and elaborate horns and frills.

In many ways, Titan resemble a frozen primordial Earth, though the greatest obstacle to Titan harboring life - - as we know it - - is the extreme cold. Even though all the chemical ingredients are present, Titan simply may not be warm enough to initiate the chemical reactions required for life. Perhaps sometime in the next decades such a mission to Titan will be a reality

Exploration of Titan - Illustration - Looking for life on Titan - An automatic probe explores a hydrocarbon marsh in search of traces of life. A robotic probe explores a frigid ethane lake on Titan.

Surface de Titan - Illustration - Titan surface - Artist's view of the surface of Titan. In the sky, the planet Saturn. It is not known what lies beneath Titan's obscuring haze.* What is known is that Titan's atmosphere is one - and - a - half times as dense as the Earth's at sea level, and its composition is roughly 90% nitrogen and 10% other complex molecules such as methane (compare this to the Earth's atmosphere which is 78% nitrogen and 20% oxygen). Sadly, Titan's thick haze would make it unlikely that a visitor to Titan's surface could look up into the sky and see Saturn itself, but what the heck.

Phobos and Mars - Illustration - Phobos and Mars - Illustration - Artist's view of Phobos, the largest of Mars's two satellites. This is how Mars and its tiny satellite Phobos might appear from a distance of about 100 miles from Phobos' surface. Phobos is over the low martian plains of Syrtis Major. Below the plains extending down to Mars' terminator and beyond is the heavily cratered Terra Sabaea. Clouds of water - ice crystals are forming at the terminator between light and dark. Looking more like a common potato than a celestial body, Phobos is actually the larger of Mars' two satellites, with a length of about 16 miles and about 11 miles across its smallest dimension. Phobos does not have enough mass for gravity to pull it into a uniform sphere like the larger satellites and planets in the Solar System. Phobos may be an asteroid long ago captured by Mars' gravity, orbiting a mere 5,800 miles above Mars' surface, making it the closest satellite to its host planet in the Solar System

Sunrise over Mercury - Artist view - Sunrise over Mercury - Artist view - On Mercury, the solar crown announces for several Earth days the sunrise. In the crepuscular sky, the Earth is represented accompanied by a few stars of the constellation Scorpio. A ghostly coronal light reveals Mercury's rugged and inhospitable surface. High up in the dark sky the bright object at the two o'clock position is the Earth, which is in full - phase due to it being almost behind the Sun in relation to Mercury. The three points of light beneath the Earth are the stars Graffias, Dshubba, and Pi Scorpii in the constellation Scorpius. A visit to Mercury would not be without its aesthetic pleasures. Given Mercury's proximity to the Sun and its lack of atmosphere, just before sunrise and sunset a visitor would be treated to a front row seat to the Sun's dazzling corona. Mercury's leisurely rotation rate* would permit the corona to be observed for as long as several Earth weeks before being either upstaged b

The Dawn probe near Ceres - Artist's view - Dawn approaches Ceres - Artist view of the Dawn probe near the dwarf planet Ceres. In February 2015 the unmanned Dawn spacecraft is scheduled to arrive at the dwarf planet Ceres. The 65 foot long, 2.5 ton probe was launched from the Earth in 2007, passed March in 2009, and went into orbit around the protoplanet Vesta in July 2011 where it stayed until September 2012. Once in orbit around Ceres, Dawn is expected to operate for about a year making observations of this largest object in the asteroid belt. In this image Dawn's three xenon electrostatic ion thrusters can be seen emitting ionized xenon's characteristic blue/magenta glow, gently propelling the probe toward Ceres. While the ion engines have relatively low specific thrust (about equal to the weight of a few sheets of paper), they can operate continuously for long periods making efficient use of the approximately 1,000 pounds of xenon propellant onboard. The wing - like solar arrays pr

Artist's view of the New Horizons probe near Pluto - New Horizons over Pluto and Charon - Artist's view of the New Horizons probe near Pluto and its largest satellite Charon. The New Horizons probe was launched on 19 January 2006 to Jupiter, then Pluto and Charon, which it will reach in 2015 and Kuiper's objects in 2020. Nasa's New Horizons unmanned spacecraft approaches dwarf planet Pluto and its moon Charon. New Horizons has been en route to Pluto since its launch from Earth in 2006 and is scheduled to make its closest approach on 14 July 2015. New Horizons is about the size and shape of a grand piano and weighed 1,054 pounds at launch. The high - gain dish antenna is about 7 feet in diameter and is employed for communication with the Earth. In this image the New Horizons spacecraft is about 15,000 miles from Pluto (upper right), 27,000 miles from its largest moon Charon (lower left) and 2.97 billion miles from the Earth. This side of the spacecraft on the left can be seen the Visibl
