PIX4620650: Nebula NGC 7635 in Cassiopee - North is at top. Seemingly adrift in a cosmic sea of stars and glowing gas, the delicate, floating apparition near the center (next to a blue tinted star) of this widefield view is cataloged as NGC 7635 - The Bubble Nebula. A mere 10 light - years wide, the tiny Bubble Nebula and the larger complex of interstellar gas and dust clouds are found about 11,000 light - years distant, straddling the boundary between the parental constellations Cepheus and Cassiopeia. Also included in the vista is open star cluster M52 (upper left), some 5,000 light - years away. The image spans about 2.7 degrees on the sky corresponding to a width of just over 500 light - years at the estimated distance of the Bubble Nebula. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory / Bridgeman Images
PIX4620665: Nebula NGC 7635 in Cassiopee - This nebula is located about 7800 light years 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. Image obtained by Isaac Newton 2.5m telescope from La Palma / Bridgeman Images
PIX4620728: Nebula NGC 7635 in Cassiopee - The Bubble Nebula: This nebula is located about 8000 light years from Earth. A star 40 times more massive than our Sun, called Wolf-Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522. Image obtained by the space telescope Hubble - The Bubble Nebula, also known as NGC 7635, is an emission nebula located 8 000 light-years away - This complete view of the Bubble Nebula allows us to fully appreciate the almost perfectly symmetrical shell which gives the nebula its name. This shell is the result of a powerful flow of gas - known as a stellar wind - from the bright star visible just to the left of centre in this image. The star, SAO 20575, is between ten and twenty times the mass of the Sun and the pressure created by its stellar wind forces the surrounding interstellar material outwards into this bubble-like form - The giant molecular cloud that surrounds the star - glowing in the star's intense ultraviolet radiation - tries to stop the expansion of the bubble. However, although the sphere already measures around ten light-years in diameter, it is still growing, owing to the constant pressure of the stellar wind - currently at more than 100,000 kilometers per hour! - This stunning new image was observed by the NASA/ESA Hubble Space Telescope / Bridgeman Images

PIX4620709: Nebula NGC 7635 in Cassiopee - The Bubble Nebula (NGC 7635) in Cassiopeia - This nebula is located about 7100 years - light from Earth. A star 40 times more massive than our Sun, 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

PIX4621115: Star Formation in the DR21 Region - Star Formation in the DR21 Region - This star formation region is about 6200 years old - light. Hidden in light visible by interstellar dust, this region rises in infrared light. Gas filaments appear in red; they emphasize the presence of aromatic polycyclic hydrocarbons (PAH); they are organic molecules composed of carbon atoms and hydrogen that could be the germs on which the first bricks of life appeared. Composite image in different wavelengths obtained by the Spitzer space telescope; in blue the visible light, in yellow and red the infrared light. Hidden behind a shroud of dust in the constellation Cygnus is a stellar nursery called DR21, which is giving birth to some of the most massive stars in our galaxy. Visible light images reveal no trace of this interstellar cauldron because of heavy dust obscuration. This image from Nasa's Spitzer Space Telescope allow us to peek behind the cosmic veil and pinpoint one of the most massive natal stars yet seen in our Milky Way galaxy. The never - before - seen star is 100,000 times as bright as the Sun. Also revealed for the first time is a powerful outflow of hot gas emanating from this star and bursting through a giant molecular cloud. This colorful image is a large - scale composite mosaic assembled from data collected at a variety of different wavelengths. Views at visible wavelengths appear blue, near - infrared light is depicted as green, and mid - infrared data is portrayed as red. The result is a contrast between structures seen in visible light (blue) and those observed in the infrared (yellow and red). The image covers an area about two times that of a full moon. The red filaments stretching across the Spitzer image denote the presence of polycyclic aromatic hydrocarbons. These organic molecules, comprised of carbon and hydrogen, are excited by surrounding i / Bridgeman Images
PIX4621162: Dark nebula and globular cluster NGC 4372 - Dark nebula and globular cluster NGC 4372 - HMSTG 436 is a molecular cloud visible near the globular cluster NGC 4372 (on the right, above the bright star Gamma Musca) in the southern constellation of the Fly. HMSTG 436 is a linear molecular cloud in the southern constellation Musca, the fly. It is easily found by targeting the globular cluster NGC 4372, visible at right, above the bright star gamma Musca / Bridgeman Images
PIX4621239: Nebulae B175 and VDB 152 in Cephee - Dark nebula B175 and reflection nebula VDB 152 - In the center of the image, a large dust trail leads to a blue nebula. This is the dark nebula, Barnard 175, which coaches the nebula by reflexion VDB 152 (Ced 201). In the center of the image a large dust band, B175; above is the reflection nebula VDB 152 (or Ced 201). These objects are located in Cepheus constellation / Bridgeman Images
