Nebula N159 in the Great Magellan Cloud - N159 star forming region in Large Magellanic Cloud (LMC): N159 is a star-forming region located in the galaxy of the Great Magellan Cloud. Image obtained by the Hubble Space Telescope (HST) - This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud (LMC). This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star form

Galaxy NGC 660 in Pisces - Galaxy NGC 660 in Pisces - The galaxy NGC 660 is located about 20 million light years ago in the constellation Pisces. It is a polar ring galaxy, a fairly rare type of galaxy that features a ring of gas and dust almost perpendicular to the main galactic plane. Image of the central part of the galaxy obtained by the Hubble Space Telescope (HST). NGC 660 is described as being a “” polar ring””” galaxy. The central region of this galaxy is considered a “” starburst”” due to the extreme amount of luminous star formation.This galaxy is estimated to be 24 million light years away. Image taken with the Hubble space telescope (HST)

Colliding galaxies NGC 4676 in Berenice's Hair - Colliding galaxies NGC 4676 - The galaxy NGC 4676 is located about 300 million years away - light from Earth. It is a system of two spiral galaxies that collide and eventually become one galaxy. This image was obtained by the Hubble Space Telescope in April 2002. Located 300 million light - years away in the constellation Coma Berenices, the colliding galaxies have been nicknamed “” The Mice”” because of the long tails of stars and gas emanating from each galaxy. Otherwise known as NGC 4676, the pair will eventually merge into a single giant galaxy. Image obtained by the Hubble space telescope in April 2002

Composite of images obtained in August 2003 and May 2004; cumulative poses of 6 hours 30 minutes - Visible-light images from the Hubble telescope's Advanced Camera for Surveys reveal where the supernova shock wave is slamming into the densest regions of surrounding gas. The bright glowing knots are dense clumps from instabilities that form behind the shock wave. The Hubble data also show thin filaments of gas that look like rippled sheets seen edge-on. These filaments reveal where the shock wave is encountering low-density, more uniform interstellar material.

The nebula is a cloud of glowing gas composed mostly of hydrogen. It excited by ultrviolet light from the embedded stars. This dostictive emission radiation is responsible for the red colour. About a quarter of the nebula is made of helium gas, the second most abundant element in the universe after hydrogen, and all the other chemical elements account for only a few percent of the total mass.

Planetary nebula IC 418 dans le Lievre/HST - IC 418: The “” Spirograph” Nebula Glowing like a multi - faceted jewel, the planetary nebula IC 418 lies about 2,000 light - years from Earth in the direction of the constellation Lepus. This photograph is from Nasa's Hubble Space Telescope, obtained with the Wide Field Planetary Camera 2. A planetary nebula represents the final stage in the evolution of a star similar to our Sun. The star at the center of IC 418 was a red giant a few thousand years ago, but then ejected its outer layers into space to form the nebula, which has now expanded to a diameter of about 0.1 light - year. The stellar remnant at the center is the hot core of the red giant, from which ultraviolet radiation floods out into the surrounding gas, causing it to fluoresce. Over the next several thousand years, the nebula will gradually disperse into space, and then the star will cool and fade away for billions of years as a white dwarf.

Image in false colors obtained with a telescope measuring 40 cm in diameter through various filters that highlight the oxygen (in blue), and the hydrogen (in red). This image shows a faint portion of the eastern veil nebula in Cygnus, a large, almost spherical glowing shell of gas, the expanding remains of a star that exploded between 5,000 and 8,000 years ago. The nebula (and thus its precursor star) is about 1900 light years distant and about 100 light years across. It is the result of the shockwave from the explosion exciting the tenuous interstellar medium and making it glow.

The region around the 4.7 magnitude star S Mon is a fascinating mixture of red fluorescent hydrogen and dark, obscuring dust lanes. Some dust patches are close enough to bright stars to reflect light from them; these appear blue for the same reason that the day - time sky is blue - because some of the interstellar particles preferentially scatter blue light. The dust is mixed with gas and this affects the appearance of the emission nebulae, giving some of the faintest a curious 'fox fur' texture in this enhanced photograph.

Omega nebula (M17) in Sagittarius - The Omega nebula (M17) in Sagittarius - View of the Omega nebula (M17/NGC 6618) located in the constellation Sagittarius at a distance of 5700 light years. This object derives its name from its looped shape reminiscent of the Greek letter when the nebula is seen in a telescope. The gas cloud is unusual in that it does not appear to be illuminated by the bright stars that commonly found in emission nebulae such as this.

This one, called CG4 (left middle of the image), is located about 1300 light years away in the constellation Pupus. Its head is 1.5 years light and its tail extends for 8 years. This cloud is a star-forming region. A spiral galaxy seen by the slice (ESO 257 - 19) is visible to the left of the blood cell. It is located 100 million years later. At the bottom left of the image, another galaxy is visible, NGC 2427. This region of the southern sky has numerous colorful faint gaseous nebulae that are very difficult to image due to thier very low surface brightness. CG4 is a ruptured cometary globule that appears to be ready to “” eat””” the distant galaxy ESO257 - 019.

Interacting galaxies NGC 454 - Interacting galaxies NGC 454 - NGC 454 is located about 164 million light years away from Earth in the southern constellation of Phenix. This pair of interacting galaxies consists of a large elliptical galaxy and an irregular galaxy. The fusion process between the two galaxies is still in its early stages and no sign of star formation caused by this interaction has been detected. Image obtained by the Hubble Space Telescope on 6 March 1997. NGC 454 is galaxy pair comprising a large red elliptical galaxy and an irregular gas - rich blue galaxy. The system is in the early stages of an interaction that has severely distorted both components. The three bright blue knots of very young stars to the left of the two main components are probably part of the irregular blue galaxy. Although the dust lanes that stretch all the way to the center of the elliptical galaxy suggest that gas has penetrated that far, no signs of star formation or nuclear activity are visibl

This image is a composite of X-ray images (blue) obtained by the Chandra Space Telescope and visible (green and red) by the Hubble Space Telescope. The study of very hot gas observed in X-ray allows us to better understand the star formation activity within this nebula. NGC 604, is one of the largest known seething cauldrons of star birth in a nearby galaxy. NGC 604 is similar to familiar star - birth regions in our Milky Way galaxy, such as the Orion Nebula, but it is vastly larger in extent and contains many more recently formed stars. This monstrous star - birth region contains more than 200 brilliant blue stars within a cloud of glowing gases some 1,300 light - years across, nearly 100 times the size of the Orion Nebula. The bright stars in NGC 604 are extremely young having formed a mere 3 million years ago. The most massive stars
