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
PIX4581074: Circumpolar - South Hemisphere - Star trails around the south celestial pole - 10h30 photographic installation on 400 ISO film around the south celeste pole. Siding Spring's 3.9m telescope dome in the foreground. By pointing a camera towards the south (or to the north in the northern hemisphere) at night, we can record the paths of stars which never set. They appear to circle the apparent position of the Earth's axis of rotation projected on the sky. The elevation of this position above the local horizon indicates our local geographical latitude, about 30 degrees south at Siding Spring. The angle swept out by the arcs is an indication of the exposure time, which was about 10.5 hours on 400 ISO colour film. This kind of exposure is only possible from an extremely dark site / Bridgeman Images
PIX4581560: The zodiacal light - The zodiacal light - The zodiacal light during astronomical dusk rises above the western horizon at the time of the spring equinox. It extends to the Pleiades. It comes from the reflection of the Sun's light on the countless interplanetary dust and draws the plane of the Solar System. Gers - France, 18/03/2009. The faint cone of light extending from the horizon along the ecliptic is known as zodiacal light. It comes from the reflexion of the sun's light off tiny interplanetary dust particles in the plane of the solar system. One can see it here from the bottom right of the image to beyond the Pleiades cluster near the center of the image. Gers, France. March 18, 2009 / Bridgeman Images

PIX4574126: Kepler - 186f, the first Earth - size Planet in the Habitable Zone - Kepler - 186f is the first Earth-sized planet in the habitable zone of its star to be discovered. It orbits Kepler - 186, a red dwarf located in the constellation of Swan, between 490 and 500 years of light from the Earth. The artist's concept depicts Kepler - 186f, the first validated Earth - size planet to orbit a distant star in the habitable zone - - a range of distance from a star where liquid water might pool on the planet's surface. The discovery of Kepler - 186f confirms that Earth - size planets exist in the habitable zones of other stars and signals a significant step closer to finding a world similar to Earth. The size of Kepler - 186f is known to be less than ten percent larger than Earth, but its mass, composition and density are not known. Previous research suggests that a planet the size of Kepler - 186f is likely to be rocky. Prior to this discovery, the “” record holder”” for the most “” Earth - like”” planet went to Kepler - 62f, which is 40 percent larger than the size of Earth and orbits in its star's habitable zone. Kepler - 186f orbits its star once every 130 days and receives one - third the energy that Earth does from the sun, placing it near the outer edge of the habitable zone. If you could stand on the surface of Kepler - 186f, the brightness of its star at high noon would appear as bright as our sun is about an hour before sunset on Earth. Kepler - 186f resides in the Kepler - 186 system about 500 light - years from Earth in the constellation Cygnus. The system is also home to four inner planets, seen lined up in orbit around a host star that is half the size and mass of the sun. The artistic concept of Kepler - 186f is the result of scientists and artists collaborating to imagine the appearance of these distant worlds / 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

PIX4633290: Meduses - Artist's view - A smack of jellyfish - Illustration of jellyfish swimming in the Panthalassic Ocean, about 500 million years ago in the Cambrian. A smack, or swarm, of jellyfish swim the Panthalassic Ocean 500 million years ago during the Cambrian Period. Jellyfish, AKA sea jellies, are free - swimming organisms from the phylum Cnidaria and may have been among the first mobile macro life forms to evolve on Earth. Their distinguishing feature is specialized cells that they use mainly for capturing prey. Their bodies consist of a non - living jelly - like substance, sandwiched between two layers of tissue that are mostly one cell thick. There are approximately 9,000 species of Cnidaria today / Bridgeman Images
