PIX4623115: Planetary nebula NGC 5189 in the fly - This nebula is located about 3000 light years from Earth in the southern constellation of the fly. Image obtained by the Gemini and Hubble telescopes (HST). NGC 5189 is a planetary nebula. At the end of its life, a star with a mass less than eight times that of the Sun will blow its outer layers away, giving rise to a planetary nebula. Some of these stellar puffballs are almost round, resembling huge soap bubbles or giant planets (hence the name), but others, such as NGC 5189 are more intricate. In particular, this planetary nebula exhibits a curious S” - shaped profile, with a central bar that is most likely the projection of an inner ring of gas discharged by the star, seen edge on. The details of the physical processes producing such a complex symmetry from a simple, spherical star are still the object of astronomical controversy. One possibility is that the star has a very close (but unseen) companion. Over time the orbits drift due to precession and this could result in the complex curves on the opposite sides of the star visible in this image. This image has been taken with the Gemini and Hubble space Telescope. / Bridgeman Images
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

Located on the grounds of the ancient fortifications, the church of Sainte Jeanne de Chantal is conceived in the nnees thirty in Byzantine Romano style, with a wide dome. Bombarded during the war, the church was not completed until 1956. / Bridgeman Images
PIX4621624: Cometary Globula CG30 in the Stern - Cometary Globule CG30 - Cometary cells are small clouds of isolated gases. These, called CG30/31/38, are located about 1300 light years ago in the constellation Pupus. The Cometary Globules CG 30/31/38 are located 1300 light years away in Vela/Puppis constellations; they appear as finger - like extensions extending out in different directions. Bright rimmed globules and their more evolved cousin the cometary globule represent fascinating dynamic structures formed by the interplay of cold molecular clouds and hot ionizing stars. Typically the head of the globule faces a hot O - type star. The blood cells are known to be the birthplace of low mass stars. The globule head of CG 30 contains the Herbig Haro object HH 120, which is the outflow signature of a pre - main sequence star / Bridgeman Images

PIX4621658: Nebula RCW38 in the constellation of sails seen in infrared by the VLT - Three - colour composite image of RCW38, obtained through three near - infrared filters. This is a region in the Milky Way at a distance of about 5,000 light years, where stars which have recently formed in clouds of gas and dust are still heavily obscured and cannot be observed in the visible part of the spectrum. Contrarily, as this image shows, they are very well seen at infrared wavelengths where the obscuration is substantially lower. The diffuse radiation is a mixture of starlight scattered by the dust and gas in the area, and atomic and molecular hydrogen line emission. RCW 38 is at a distance of ~ 1.7 kpc (~ 5500 light years) from us, near the famous Vela supernova remnant and the Gum nebul / Bridgeman Images
