Artist's concept of an Earth buried by layers of cities built by a hundred million generations of our descendants. The Earth as it may appear 500 million years from now. By this time the Sun will have grown considerably hotter due to its natural evolution as a type G5V star, making the Earth a hotter place as well. While it is unlikely that beings that look or think anything like us would still populate the Earth 500 million years from now (humans would have evolved on to other forms; evidence 500 million years ago the most highly evolved life forms on the Earth were fish), if we were still here in our present form, we would likely find the Earth very inhospitable.
Artist's concept showing how the surface of the Earth may have appeared beneath its clouds about 500 million years after its birth, also known as the Hadean eon. Massive volcanoes and lava fields still dominate the landscape. In a few million years rain will begin falling, further cooling the crust. In about another 200 million years the first living microbes will call the Earth home.
A full Neptune washes Triton's frozen surface with an indigo light, the only source of illumination on this now Triton's dark side. Fortuitous alignment of the Sun, Triton and Neptune causes this satellite's shadow to fall on Neptune's distant cloud tops 220 thousand miles away. This view is from within a deep, crater-like depression on Triton's northern hemisphere. There are many such crater-like depressions on Triton's northern hemisphere. While these depressions look like impact craters, their similar size and spacing suggest that they were created by some other process. Their origin is still unknown, but may involve local melting and collapse of the icy surface. The scarcity of impact craters suggest that this surface is relatively young by solar system standards, probably less than a few billion years old. The depression in this image is about 15 miles in diameter; the ridge on the horizon is approximately seven miles from the mesa in the foreground.
Artist' concept showing Mars and its even smaller satellite Deimos might appear from a distance of about 100 miles from the surface of Deimos. Deimos is seen passing over Acidalia Planitia, an albedo feature that has been observed by Earth-bound astronomers since the 19th century. To the southwest are the fog-filled canyons of Valles Marineris, the westernmost of which are still in darkness. Beyond Mars, immediately to the left of its night side, is Phobos at a distance of 20,000 miles. The two bright objects in the lower left are the stars Beta Gruis and Al Nair in the southern constellation Grus. Deimos does not possess enough mass to pull itself into a sphere. Its shape is oblong with a length of about 10 miles and only 6 miles wide at its smallest dimension. Orbiting 14,600 miles above Mars' surface, Deimos completes one revolution every 30 hours.
The northwest side of Olympus Mons' 20,000 foot scarps cast long shadows into the water mist and dust-filled atmosphere over the plains of the Tharsis Bulge. In the sky immediately above Olympus Mons' caldera are, left to right, Mars' satellites Deimos and Phobos. Nearly as large as the state of Arizona and three times the height of Mount Everest, Olympus Mons is the largest volcano, and mountain, in the Solar System. It is thought to be very old, though its last eruption may have been as (geologically) recent as 40 million years ago. Olympus Mons may yet still be an active volcano.
