PIX4620579: Nebula NGC 7129 in Cephee - Reflection nebula NGC 7129 in Cepheus - Nebula by reflexion located 3300 years - light of the Earth. This nebula houses very young stars, aged less than a million years old. NGC 7129 is a star forming region located in Cepheus constellation, 3300 light years from us. Several Herbig Haro objects are visible in this nebula. Herbig - Haro objects are small emission nebulae found around young developing stars (protostars) and which are believed to be transient in their nature, for they only exist for a few thousand years / Bridgeman Images
PIX4620626: Nebula NGC 7635 and M52 clusters in Cassiopee - Nebula NGC 7635 and M52 clusters in Cassiopee - Nebula NGC 7635 is located about 7800 years - light from Earth. A massive star, called Wolf - Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522, 40 times more massive than our Sun. M52, top left, is an open cluster containing about 200 stars / Bridgeman Images
PIX4620681: Nebula NGC 7635 in Cassiopee - Bubble Nebula (NGC 7635) in Cassiopeia - This nebula is located about 7100 years - light from Earth. A massive star, called Wolf - Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522. The Bubble Nebula in Cassiopeia is one of the most dramatic emission nebulae visible in the northern hemisphere. Lying at a distance of about 7,000 light - years away and spanning six light - years in diameter, NGC 7635 is quite bright with a magnitude of 7.0. The star in the middle of the bubble, BD+602522, is responsible for this stunning site, for this very hot star emits so much UV radiation that it is able to also heat and excite the surrounding dust and gas, thus emitting its own radiation. It is a Wolf - Rayet star, a very luminous star and also very short - lived. This Wolf - Rayet star is 40 times as massive than our sun / Bridgeman Images
PIX4626158: Astronauts on Titan - Illustration - First steps on Titan - Astronauts explore Titan's surface. Perhaps some day in the far future humans will set foot on Saturn's mysterious moon Titan, one of the most interesting worlds in the Solar System. Larger than the planet Mercury, Earth's moon, and the dwarf planet Pluto, and second only in size to Jupiter's satellite Ganymede, Titan is the only known extraterrestrial world with a dense atmosphere that realistically could be visited by humans. A visit to Titan would require a space journey of a year or more and traverse over 700 million miles. Beneath Titan's 350 miles of atmosphere, intrepid explorers would likely find a dark, forbidding landscape of rock, ice, and possibly tarry layers of hydrocarbons and lakes of liquid ethane and/or methane (AKA natural gas). The Surface temperature would be around minus 300* F, cold enough to freeze exposed human tissue within seconds. There would be no oxygen to breathe, and any water to be found would be as hard and dense as granite. Despite these harsh conditions, Titan could yet yield secrets regarding the origin of life itself as it is believed that, with the exception of the extreme cold, Titan resemble the primordial Earth at the time living organisms first appeared. In this image, Titan's first human visitors are protected by thick suits and helmets to shield them from the extreme cold - - and possibly toxic compounds such as hydrogen cyanide. They carry their own oxygen as Titan's atmosphere is primarily nitrogen with lesser amounts of argon, methane and other gases. Each explorer also carries “” head”” lights attached to their helmets to help them navigate a terrain that receives only 1/1000th the Sun's illumination on the Earth; while this means that noon on Titan would appear relatively dim, it would yet be over 300 times brighter than the Earth under a full moon / Bridgeman Images
PIX4626499: Crab Nebula seen in different wavelength - The Crab Nebula in multi wavelength: M1, the Crab Nebula, is the rest of a supernova that exploded on July 4, 1054. It is located about 6500 light years from Earth in the constellation Taurus. At the heart of this nebula is a pulsar. To obtain this photo, different observatories and telescopes combined their observations; the VLA provided the radio image (in red), the Spitzer telescope the infrared image (in yellow), the Hubble telescope for the visible part (here in green), XMM-Newton the ultraviolet image (in blue) and the Chandra telescope for X-ray data (purple). The pulsar is the bright spot in the center of the image. The unusual image was produced by combining data from telescopes spanning almost the entire electromagnetic spectrum, from radio waves to X-rays. The Karl G. Jansky Very Large Array (VLA) provided information about the nebula gathered in the radio regime (colored in red). Nasa's Spitzer Space Telescope took images in the infrared (yellow). The NASA/ESA Hubble Space Telescope provided the images made in optical wavelengths (colored in green). ESA's XMM-Newton telescope observed the Crab Nebula in the ultraviolet (blue) and Nasa's Chandra X-ray Observatory provided the data for X-ray radiation (purple). The Crab Nebula, located 6500 light-years from Earth in the constellation of Taurus, is the result of a supernova explosion which was observed by Chinese and other astronomers in 1054. At its centre is a pulsar: a super-dense neutron star, spinning once every 33 milliseconds, shooting out rotating light-like beams of radio waves and visible light. Surrounding the pulsar lies a mix of material; some of it was originally expelled from the star before it went supernova, and the rest was ejected during the explosion itself. Fast-moving winds of particles fly off from the neutron star, energising the dust and gas around it. / Bridgeman Images

PIX4628063: Total Eclipse of Sun. 01/08/2008 - Total Solar Eclipse of 2008 august 01 - Composite of images showing the solar crown, the ash light (the Moon lit by the Earth) the stars around the Sun (with the cluster of stars M44 at the top right) and the planet Mercury (bright dot on the left). 01/08/2008, Mongolia. Data from two different cameras were used for this image creation. The open cluster M 44 Praesepae (NGC 2632) dominates the star field. The bright object in the left part of the image is Mercury. The solar corona is traceable up to the distance of 20 solar radii. The position of the Moon represents the situation 62 seconds after the second contact (18:04:37 mongolia local time). Display of the solar corona, lunar surface and stars in the resulting image are highly beyond the ability of human vision during the eclipse / Bridgeman Images
TEC4628196: Entrepots de Bercy, Paris 12th arondissement. Louis XIV (1638-1715) built the first wine warehouses in Bercy because Paris was home to one of the largest vineyards in Europe. These warehouses reached their peak in the 19th century, becoming the world's largest centre for wine and spirits trade. The activities of the warehouses began to declinate in the 20th century with the destruction of the fortifications of Thiers, 1920-1929, the success of the railway and the evolution of storage techniques. It is now Bercy Village and Bercy Park that settled on the old warehouses. The surrounding area still resonate with the memory of old activities: rue de Pommard, rue de Chablis, rue de Macon... / Bridgeman Images
