PIX4580204: Circumpolar - Star trails around north celestial pole - Photographic pose around the polar star. Long exposure image; because the earth rotates on it's own axis, during the exposure the stars seem to revolve around a point in the sky very near to Polaris / Bridgeman Images
PIX4582940: Remnants of the supernova Cassiopee A in X-rays - visible and infrared - This stunning picture of the supernova remnant Cassiopeia A (Cas A) is a composite of images taken by three of Nasa's Great Observatories. Infrared data from the Spitzer Space Telescope are colored red; optical data from the Hubble Space Telescope are yellow; and X - ray data from the Chandra X - ray Observatory are green and blue. Cas A is the 300 - year - old remnant created by the supernova explosion of a massive star. Each Great Observatory image highlights different characteristics of the remnant. Spitzer reveals warm dust in the outer shell with temperatures of about 10 degrees Celsius (80 degrees Fahrenheit), and Hubble sees the delicate filamentary structures of warmer gases about 10,000 degrees Celsius. Chandra shows hot gases at about 10 million degrees Celsius. This hot gas was created when ejected material from the supernova smashed into surrounding gas and dust at speeds of about ten million miles per hour. A comparison of the infrared and X - ray images of Cas A should enable astronomers to better understand how relatively cool dust grains can coexist in the superhot gas that produces the X - rays. It should also help to determine whether most of the dust in the supernova remnant came from the massive star before it exploded, or from the rapidly expanding supernova ejecta. The turquoise dot at the center of the shell may be a neutron star created during the supernova. Blue Chandra data were acquired using broadband X - rays (low through high energies); green Chandra data correspond only to intermediate energy X - rays; yellow Hubble data were taken using a 900 nanometer - wavelength filter, and red Spitzer data are from the telescope's 24 - micron detector. Observation Dates 9 pointings between Feb 8 - May 5, 2004 Observation Time 11 days, 14 hours Distance Estimate About 10,000 light year / Bridgeman Images

PIX4584791: Artist view of Cygnus X-1 - Cygnus X-1 is a binary star X and was the first black hole candidate. This system consists of the 226868 HD star, a supergeant star, orbiting around a black hole. A stellar black hole is born from the gravitational collapse of a massive star. The stellar black holes have a mass of some solar masses. A black hole is a region of space whose gravitation is so strong that it will prevent any form of material or radiation from escaping. Cygnus X-1 is an X-ray binary system and the first black hole candidates to be discovered / Bridgeman Images
PIX4590268: Constellation of the Southern Cross - The Southern Cross - The Southern Cross and the Alpha and Beta stars of Centaurus. Crux, the Southern Cross, is the smallest constellation in the sky yet one of the most distinctive, at least to those of us who live in the southern hemisphere. It was once part of Centaurus, where the bright stars Acrux and Mimosa could easly be imagined as the rear hooves of the rearing mythical centaur. However, when Christian sailors began to explore southwards in the 16th century, this memorable asterism took on a new significance. The cross appears on the national flags of several southern hemisphere countries, including Australia, though it can be seen on the southern horizon from the tropic of Cancer, 23.5 degrees north of the equator. Along with the Southern Cross is a very distinctive dark shape known as the Coalsack, much used by southern hemisphere astronomers as an indicator of a dark sky, especially if the sixth magnitude star embedded in it is visible. The long axis of the southern cross points towards the south celestial pole, so the cross itself acts as a very convenient circumpolar clock, compasset and calendar / Bridgeman Images

PIX4608442: Planetary system around Trappist-1 - Artist's impressions of the TRAPPIST-1 planetary system: Artist's view of extrasolar planets around the red dwarf star TRAPPIST-1. At least seven exoplanets the size of the Earth are orbiting this star 40 light years ago in the constellation Aquarius. All could contain water. This artist's impression shows several of the planets orbiting the ultra-cool red dwarf star TRAPPIST-1. New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest that they are rich in volatile materials, probably water / Bridgeman Images
PIX4613932: Leo 1 dwarf galaxy in the Lion - Leo 1 dwarf galaxy - Leo 1 is located about 900,000 light years from Earth. It belongs to the local group, just like our galaxy or Andromede galaxy. It has only been known since the 1950s; it is difficult to observe due to the proximity of the Regulus star, thousands of times brighter. Image obtained from the 3.9m telescope of Siding Spring. The 'Local Group' of galaxies, to which the Milky Way belongs, contains more dwarf galaxies than any other type. The low surface brightness and lack of bright stars makes them difficult to study, even with a large telescope. Leo I presents particular problems because the galaxy appears only 20 arc minutes (less than the apparent diameter of the Moon) from the brilliant star Regulus and special precautions had to be taken to prevent scattered light from the star obliterating its feeble image. The plates from which this picture was made (the first in colour of a dwarf elliptical galaxy) will be used to learn more about the origins of star formation in these light - weight objects / Bridgeman Images

PIX4669145: Earth seen by satellite DSCOVR - Earth seen by satellite DSCOVR: Earth photo obtained by satellite Deep Space Climate Observatory (DSCOVR) on July 6, 2015. This satellite, launched on 11 February 2015, and placed in orbit 1.6 million km, at the point of Lagrange L1 (about 4 times farther than the Moon's orbit), provides views of the Earth as a whole - The journey has been a long one for the Deep Space Climate Observatory (DSCOVR). Once known as Triana, the satellite was conceived in 1998 to provide continuous views of Earth, to monitor the solar wind, and to measure fluctuations in Earth's albedo. The mission was put on hold in 2001, and the part-built satellite ended up in storage for several years with an uncertain future. In 2008, the National Oceanic and Atmospheric Administration (NOAA), NASA, and the U.S. Air Force decided to refurbish and update the spacecraft for launch - On February 11, 2015, DSCOVR was finally lofted into space by a SpaceX Falcon 9 rocket. After journey of about 1.6 million kilometers (1 million miles) to the L1 Lagrange Point, the satellite and its Earth Polychromatic Imaging Camera (EPIC) has returned its first view of the entire sunlit side of Earth. At L1-four times farther than the orbit of the Moon - the gravitational pull of the Sun and Earth cancel out, providing a stable orbit and a continuous view of Earth. The image above was made by combining information from Epic's red, green, and blue bands. (Bands are narrow regions of the electromagnetic spectrum to which a remote sensing instrument responds. When EPIC collects data, it takes a series of 10 images at different bands - from ultraviolet to near infrared.) / Bridgeman Images

PIX4672476: Umnak Island - Aleutian Islands - Alaska - Umnak Island - Aleutian Islands - Alaska: Umnak Island is one of the Fox Islands, belonging to the Aleutian Islands in Alaska, USA. With an area of more than 1,776 km, it is the third largest of the Aleutian Islands. At the top right is the Okmok caldera (erupted in 2008), below the Vsevidof volcano; below the left, the Ile des Quatre Montagnes. Image obtained on 3 May 2014 by the Landsat-8 satellite. On May 3, 2014, the Landsat 8 satellite acquired this natural-color image of Umnak Island and its volcanic neighbors in the Aleutian Island chain. Part of the Fox Islands, Umnak is the third largest in the Aleutian chain and lies just southwest of Unalaska. Umnak is mostly unpopulated, with roughly 40 people living in the village of Nikolski near the southwest tip of the island. Being a volcanic island, Umnak has numerous mud pots, hot springs, and the only geysers in Alaska. The landscape is dominated by volcanoes. On the northern half of the island, Okmok - site of the 2008 eruption - rises 1073 meters (3,520 feet) above sea level as a broad shield volcano with a caldera nestled near the top. A crater lake sits amidst the volcanic ash and debris in the caldera. Mount Vsevidof, a symmetrical stratovolcano, rises 2149 meters (7,050 feet) and dominates the skyline of the southern portion of Umnak Island. The volcanic Islands of the Four Mountains are also visible in the lower left of the wide image / Bridgeman Images
