PIX4643515: Cassini spacecraft with Enceladus Geysers - Artist's view of the Cassini probe observing geysers on the surface of Enceladus, one of Saturn's satellites. The Cassini-Huygens probe was launched on 15 October 1997 and has been placed in orbit around Saturn since 1 July 2004. Cassini deliberately flies through the enigmatic geysurs of Encaledus, as the slim cresent of Saturn rises above the horizon / Bridgeman Images
PIX4633308: The Earth 600 million years ago - Artist's view - Ediacaran Earth - The Earth seen about 600 million years ago after an important period of glaciation. This is how the Earth may have appeared 600 million years ago following the Cryogenian “” Snowball Earth”” period. The worldwide glaciers have melted and the ocean is largely liquid again. During this, the Ediacaran period, it is hypothesized that all of the Earth's landmasses had merged into a single supercontinent known as Pannotia, also known as the Vendian supercontinent. Surrounding this massive landmass is the vast Panthalassic Ocean, also known as Panthalassa. While the ocean was home to a variety of evolving multicellular life forms including the ubiquitous Dickinsonia costata, it is not believed that life had moved to dry land with possible exception of bacteria and other microbial colonies / Bridgeman Images
PIX4622058: Horsehead Nebula (B33) in Orion - Horsehead Nebula (B33) in Orion - The horse's head nebula, Barnard 33, is a dark nebula located in front of the IC 434 nebula about 1500 years - light from Earth in the constellation Orion. At the bottom left, the nebula NGC 2024 with just above the star Alnitak, a supergeant star belonging to the Orion Baudrier. Towards the center of the image, a reflexion nebula, NGC 2023. The Horsehead Nebula (also known as Barnard 33 in nebula IC 434) is a dark nebula in the Orion constellation at approximately 1,500 light years from Earth. On bottom left of the image is the Flame Nebula (NGC 2024) with star Alnitak which belongs to the Belt of Orion; in the center, the reflection nebula NGC 2023.

PIX4616824: Mars and Deimos - Illustration - Mars and Deimos - Illustration - Artist's view of Deimos, the smallest of Mars's two satellites. This is how Mars and its even smaller satellite Deimos might appear from a distance of about 100 miles from the surface of Deimos. Deimos is 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. Like it's larger companion Phobos, Deimos does not possess enough mass to pull itself into a sphere; its shape instead is oblong with a length of about 10 miles and only 6 miles wide at its smallest dimension. Like Phobos, Deimos may be an asteroid long ago captured by Mars' gravity. Orbiting 14,600 miles above Mars' surface, Deimos completes one revolution every 30 hours / Bridgeman Images
