PIX4604915: Launch of the Dnepr - Dnepr rocket launch - Launch of the Cryosat - 2 satellite on board a Dnepr rocket, 8 April 2010. Successful launch for ESA's CryoSat - 2 ice satellite Europe's first mission dedicated to studying the Earth's ice was launched on April 8 2010 from Kazakhstan. From its polar orbit, CryoSat - 2 will send back data leading to new insights into how ice is responding to climate change and the role it plays in our 'Earth system'. The CryoSat - 2 satellite was launched at 15:57 CEST (13:57 UTC) on a Dnepr rocket provided by the International Space Company Kosmotras from the Baikonur Cosmodrome in Kazakhstan. The signal confirming that it had separated from the launcher came 17 minutes later from the Malindi ground station in Kenya / 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
PIX4611429: M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is located about 60 million years ago - light from Earth, in the heart of the Virgin's cluster. M87 is the brightest radio source in the constellation, it is also called Virgo A. Image made with Siding Spring's 3.9m telescope. Messier 87 (NGC 4486) is at the heart of the Virgo cluster and has a mass many times that of the Milky Way, itself no lightweight. Unlike our galaxy however, M87 is an elliptical galaxy. Though it appears more - or - less spherical on this photograph, a deep image shows it to be markedly elongated. Also unlike the Milky Way, M87 contains relatively little gas and dust. It is composed mainly of cool stars, which gives it a yellowish colour, in contrast to the blue of spiral galaxies. Despite the lack of star - forming materials, M87 is not a quiescent backwater. It is a powerful source of radio waves and the orbits of stars near its nucleus suggest they are held by a very massive, extremely compact core. Also, from the nucleus (but not seen here) extends a curious jet, all of which suggests that a massive black hole is hidden in the bright core of the galaxy / Bridgeman Images
