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.

PIX4623214: Planetary nebula NGC 6537 in Sagittarius - Hubble observations have revealed huge waves sculpted in the Red Spider nebula. This warm and windy planetary nebula harbours one of the hottest stars in the Universe and its powerful stellar winds generate waves 100 billion kilometers high - intimidating for even the bravest space surfers. The Red Spider Nebula, NGC 6537, is a striking 'butterfly' or bipolar (two - lobed) planetary nebula. Planetary nebulae are the glowing embers of ordinary stars, such as our Sun. At the end of their lives these stars expel most of their material into space, often forming a two - lobed structure as in the case of the Red Spider. These waves are driven by stellar winds radiating from the hot central star, much as a wind passing over a lake can generate waves on the water. The waves reach peaks 100 billion kilometers high and must have been produced by a powerful wind blowing with a speed of 2000 - 4500 kilometers per second (about 7 - 16 million km/hr). The waves themselves move outwards at a slower rate of 300 km/s (about 1 million km/hr). To add to these challenging climatic conditions, this nebula is not only windy, but also hot. The temperature of the gas waves is a scorching 10,000 K Detailed investigations of the Hubble image have shown that the central white dwarf, the remaining compact core of the original star, must have a temperature of at least half a million degrees, making it one of the hottest stars known. It is so hot that it is invisible to Hubble's eye and emits primarily in X - rays. The waves are generated by supersonic shocks formed when the local gas is compressed and heated in front of the rapidly expanding lobes. Atoms caught in the shocks radiate the visible light seen in this image. The process appears to have been underway long enough to make the edges of the lobe walls look as if they have started to fracture into wave crests. The Red Spider Nebula is located about 3000 light - years away in the constell / Bridgeman Images

PIX4623563: Helix planetary nebula (NGC 7293) in Aquarius by HST - Helice's planetary nebula, located in Aquarius, is one of the closest to Earth (650 years - light) and is also one of the most extended. Its apparent diameter is about half of the full moon. It was obtained from two clicks taken by the ACS panoramic camera of the Hubble Space Telescope and from the 90 cm telescope of Kitt Peak in Arizona. It reveals unseen details of the filamentary structure of the blue and red gas ring that surrounds the starred star (in the centre of the nebula). In the center of the image, the star that expelled its material became a white dwarf / Bridgeman Images
