PIX4616438: March: Victoria crater. - March: Victoria Crater at Meridiani Planum - View of the Victoria crater obtained by the HIRISE camera on board the Mars Reconnaissance orbiter probe. This crater is 800 meters in diameter. The opportunity rover reached this crater on September 27, 2006. After exploring about a quarter of the crater's edges, the rover descended almost a year later to begin an exploration of the crater's interior. Victoria Crater, about 800 meters (one - half mile) in diameter, has been home ground for Nasa's Mars Exploration Rover Opportunity for more 14 of the rover's first 46 months on Mars. Opportunity first reached the crater's rim on Sept. 27, 2006, during the 951st Martian day, or sol, of the rover's work in the Meridian Planum region of Mars. The rover then explored clockwise about one - fourth of the way around the rim before returning to a point close to its first overlook. On the mission's 1,293rd sol (Sept. 13, 2007), Opportunity began a sustained exploration of the interior of the crater, entering at an alcove called “” Duck Bay””” on the western side of Victoria.

PIX4617526: Nebula NGC 1333 in Persee infrared view - NGC 1333 star - forming region seen in infrared. - NGC 1333 is a nebula located between 700 and 1000 years - light of the Earth. It's a reflexion nebula and a star-forming region. Viewed here in infrared by the Spitzer space telescope, young stars become visible. Jets of matter, in yellow - green, emerge from extremely young embryonic stars. Located between 700 and 1000 light - years from Earth in the constellation Perseus, the reflection nebula called NGC 1333 is seen here in infrared pictured by the Spitzer Space Telescope. The young stars in NGC 1333 do not form a single cluster, but are split between two sub-groups. One group is to the north near the nebula, dominated by the infrared light from warm dust shown as red in the image. The other group is south, where the features shown in yellow and green abound in the densest part of the natal gas cloud. The knotty yellow - green features are glowing shock fronts where jets of material, spewed from extremely young embryonic stars, are plowing into the cold, dense gas nearby / Bridgeman Images

PIX4618093: Nebula M43 in Orion - M43 nebula in Orion - Nebula M43 (NGC 1982) is part of the great Nebula of Orion (M42), a vast region of star formation. This image obtained by the Hubble Space Telescope (HST) shows a detail of the nebula people of bright young stars accompanied by very young stars still surrounded by their cocoon of dust. The NASA/ESA Hubble Space Telescope has taken a close - up view of an outer part of the Orion Nebula's little brother, Messier 43. This nebula, which is sometimes referred to as De Mairan's Nebula after its discoverer, is separated from the famous Orion Nebula (Messier 42) by only a dark lane of dust. Both nebulae are part of the massive stellar nursery called the Orion molecular cloud complex, which includes several other nebulae, such as the Horsehead Nebula (Barnard 33) and the Flame Nebula (NGC 2024). This view shows several of the brilliant hot young stars in this less - studied region and it also reveals many of the curious features around even younger stars that are still cocooned by dust. This picture was created from images taken using the Wide Field Channel of Hubble's Advanced Camera for Surveys. Images through yellow (F555W, coloured blue) and near - infrared (F814W, coloured red) filters were combined. The exposure times were 1000 s per filter and the field of view is about 3.3 arcminutes across / Bridgeman Images

PIX4618722: Nebula of the cone NGC 2264 and S star Monocerotis - NGC 2264 and S Monocerotis - Region H II located about 2600 years - light from Earth. The bright star is S Monocerotis, a star of magnitude 4.7. Image obtained by Siding Spring's 3.9m telescope. 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. Some of the wispy tendrils of nebulosity are Herbig - Haro objects, jets of matter ejected from newly - formed stars still hidden within the nebula. About 250 stars have been recognised as members of NGC 2264 which is at a distance of about 2700 light years / Bridgeman Images

PIX4617509: Nebula NGC 604 in the galaxy M33 - NGC 604 star forming nebula - NGC 604, is a very large star-forming region located in the galaxy M33 of the Triangle. 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 in NGC 604 exceed 120 times the mass of our Sun, and their surface temperatures are as hot as 72,000 degrees Fahrenheit (40,000 Kelvin). Ultraviolet radiation floods out from these hot stars, making the surrounding nebular gas fluoresce. NGC 604 lies in a spiral arm of the nearby galaxy M33, located about 2.7 million light - years away in the direction of the constellation Triangulum. The image is a composite of images taken in X - ray (in blue) by Chandra X - Ray observatory and in optical (red and green) by the Hubble space telescope. It shows a divided neighborhood where some 200 hot, young, massive stars reside. Bubbles in the cooler gas and dust have been generated by powerful stellar winds, which are then filled with hot, X - ray emitting gas. Scientists find the amount of hot gas detected in the bubbles on the right side corresponds to the amount entirely powered by winds from the 200 hot massive stars. The situation is different on th / Bridgeman Images

PIX4618132: Nebula M78 in Orion - M78 nebula in Orion - The nebula M78 (NGC 2068) is located about 1300 years - light from Earth and extends over 4 years - light. M78, (NGC 2068) is part of the Orion complex, a large region of star - forming gas and dust centred around M42 and M43. It is the brightest diffuse reflection nebula in the sky, and fairly easy to see with binoculars (and almost visible to the naked eye, claim some observers). M78 is some 1600 light - years away and around 4 light - years across / Bridgeman Images

PIX4619552: Center of the Trifid Nebula (M20) - Center of the Trifid Nebula - The Trifid Nebula (M20) is located between 5000 and 10,000 years - light of the Earth in the constellation of Sagittarius. This image obtained by the Hubble space telescope shows the center of this nebula. A group of bright stars is visible in the center of the image near the dark bands of interstellar dust. These stars are young, blue, massive and extremely hot stars; they are O-type stars and the radiation they emit influence the evolution and structure of the nebula. Trifid Nebula, also known as Messier 20 and NGC 6514, lies within our own Milky Way Galaxy between 5000 and 10 000 light - years from Earth, in the constellation Sagittarius. This image from the Hubble Space Telescope offers a close - up view of the center of the Trifid Nebula, near the intersection of the dust bands, where a group of recently formed, massive, bright stars is easily visible. These stars, which astronomers classify as belonging to the hottest and bluest types of stars called type “” O,””” are releasing a flood of ultraviolet radiation that dramatically influences the structure and evolution of the surrounding nebula / Bridgeman Images
