PIX4609403: Spiral galaxy M74 in Pisces - Spiral galaxy M74 in Pisces - Image of the spiral galaxy M74 (NGC 628). This galaxy is about 80,000 light years and is 30 million light years apart. Viewed face on, as it appeared about 30 million years ago, M74 is considered to be one of the most photogenic spiral galaxies in the sky. The galaxy is rich in young bright blue stars and glowing red regions of dust and molecular hydrogen where new stars are being created. M74, however, is quite camera shy - it has a low surface brightness that makes it challenging for both visual observers and astrophotographers to see it's entire form. The Chandra X - Ray observatory, discovered M74 to be the home of a super massive black hole, tucked away in one of it's outer arms. This black hole is one of the largest ever discovered and has the mass of over 10,000 suns. Thirty six, fifteen minute photographs were combined to create this picture, with a total exposure time of almost nine hours. The images were taken with a 20 inch Ritchey - Chretien telescope and an eleven mega - pixel camera at f/8 from high in the south central mountains of New Mexico / Bridgeman Images
PIX4630355: La formation du système solaire - Vue d'artiste - Artist's impression of the development of the Solar System - Vue d'artiste de planete en formation dans le disque de gaz et de dusts (disque protoplanetaire) autour de son toile. This artist's impression shows four stages of the development of the inner Solar System over a period of almost five billion years. The top panel shows the earliest stage where the debris disc around the Sun was composed of gas and tiny particles, typically less than one millimetre across. At the second stage the particles have formed large clumps, roughly 100 kilometers across and, similar to the asteroid Lutetia. These bodies in turn formed the rocky planets including the Earth, shown in the third panel down. Over the subsequent four billion years the surface of the Earth developed to what we know now under the influence of meteor bombardment that delivered volatile materials including water, and the evolution of life on its surface / 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
PIX4610684: Spiral galaxy NGC 3370 in the Lion - Spiral galaxy NGC 3370 in Leo - The spiral galaxy NGC 3370 is located about 100 million years away - light from Earth. In November 1994, light emitting from a supernova type Ia, SN 1994ae, part of this galaxy, reached Earth. In this image taken by the Hubble space telescope in May 2003, this supernova is no longer detectable. On the other hand, the telescope was able to observe in this galaxy cepheides, variable stars used to accurately measure distances in the universe and calculate the rate of expansion of the universe. Many galaxies are visible in the background. The majestic dusty spiral, NGC 3370, looms in the foreground in this NASA Hubble Space Telescope image. Recent observations taken with the Advanced Camera for Surveys show intricate spiral arm structure spotted with hot areas of new star formation. In November 1994, the light of a supernova in nearby NGC 3370 reached Earth. This stellar outburst briefly outshone all of the tens of billions of other stars in its galaxy. Although supernovae are common, with one exploding every few seconds somewhere in the universe, this one was special. Designated SN 1994ae, this supernova was one of the nearest and best observed supernovae since the advent of modern, digital detectors. It resides 98 million light - years (30 megaparsecs) from Earth. The supernova was also a member of a special subclass of supernovae, the type Ia, the best tool astronomers have to chart the growth rate of the expanding universe. Other, fainter stars of known brightness can be observed in the same galaxy. These stellar “” standard candles”” are the Cepheid variable stars, which vary regularly in brightness with periods that are directly related to their intrinsic brightness, and thus allow the distance to the galaxy””” and the supernova””” to be determined directly / Bridgeman Images
PIX4610701: Galaxies M105, NGC 3384 and NGC 3389 in the Lion - Galaxies M105, NGC 3384 and NGC 3389 in Leo - These galaxies belong to the group of Leo 1 galaxies. Below is the elliptical galaxy M105, type E1, located about 40 million years ago - light from Earth; above, NGC 3384, at the top NGC 3389, a galaxy in the background. M105 (bottom) is a type E1 elliptical galaxy and the brightest member of the Leo I galaxy grouping. The entire group is about 40 million light - years away. Also visble are galaxies NGC 3384 (above and right of center), which is part of the Leo I group, and NGC 3389 (top left), which is a more distant background galaxy / Bridgeman Images
PIX4610775: Spiral galaxy NGC 3621 in Hydra - Galaxy NGC 3621 in Hydra - The spiral galaxy NGC 3621 is located about 22 million light years away from Earth in the southern constellation of Hydra. Image obtained from the 2.2 meter MPG/ESO telescope of the La Silla Observatory. Spiral galaxy NGC 3621 is located in the southern constellation Hydra at 22 million light years from the sun. Image taken with the Wide Field Imager on the MPG/ESO 2.2 - metre telescope at Eso's La Silla Observatory in Chile. This galaxy appears to be a fine example of a classical spiral but it is in fact rather unusual: it does not have a central bulge and is therefore described as a pure - disc galaxy / Bridgeman Images

TEC4602580: Stained glass windows of the Cathedrale de Chartres (Eure and Loire). Built partly from 1145, and rebuilt in twenty-six years after the fire of 1194, it is the monument par excellence of French Gothic art. Its vast nave of the purest ogival style, its porches with admirable mid-12th century sculptures, its shimmering set of stained glass windows from the 12th and 13th centuries make it an exceptional masterpiece and remarkably well preserved. The Cathedrale de Chartres has been listed as a UNESCO World Heritage Site since 1979. Photography 30/06/05. / 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
