PIX4580080: The coldest place on Mars - Coolest place on Mars: Detail of the ice cap of the southern pole of Mars, composed mainly of carbon dioxide. This dry ice accumulates on the surface mainly in winter, the temperature of this area can sometimes drop to 130 degrees Celsius below zero. Image obtained on August 29, 2016 by the HIRISE camera on board the Mars Reconnaissance orbiter probe. HIRISE is a 50 cm telescope that observes visible and near infrared. The polar cap is made from carbon dioxide (dry ice), which does not occur naturally on the Earth. The circular pits are holes in this dry ice layer that expand by a few meters each Martian year. New dry ice is constantly being added to this landscape by freezing directly out of the carbon dioxide atmosphere or falling as snow. Freezing out the atmosphere like this limits how cold the surface can get to the frost point at -130 degrees Celsius (-200 F). Nowhere on Mars can ever get any colder this, making this coolest landscape on Earth and Mars combined / Bridgeman Images
PIX4580152: Cluster of stars NGC 299 in Toucan - Open cluster NGC 299 in Tucana: NGC 299 is an open cluster located in the galaxy of the Little Magellan Cloud. Image obtained by the Hubble Space Telescope (HST). NGC 299 is an open star cluster located within the Small Magellanic Cloud just under 200 000 light-years away. Open clusters such as this are collections of stars weakly bound by the shackles of gravity, all of which formed from the same massive molecular cloud of gas and dust. Because of this, all the stars have the same age and composition, but vary in their mass because they formed at different positions within the cloud. This unique property not only ensures a spectacular sight when viewed through a sophisticated instrument attached to a telescope such as Hubble's Advanced Camera for Surveys, but gives astronomers a cosmic laboratory in which to study the formation and evolution of stars - a process that is thought to depend strongly on a star's mass / Bridgeman Images

PIX4615694: March: Rover Spirit - Self Portrait - The Rover Spirit used his panoramic camera to take several images and create this mosaic on August 27, 2005. This self-portrait shows the accumulation of Martian dust on the rover and its solar panels. This dust is less present than a year ago. The Rover Spirit landed on Mars in the Gusev crater area, July 4, 2004 / Bridgeman Images
