4Vikram Posted January 22, 2016 Report Posted January 22, 2016 Latest News: Resembling an opulent diamond tapestry, this image from NASA's Hubble Space Telescope shows a glittering star cluster that contains a collection of some of the brightest stars seen in our Milky Way galaxy. Called Trumpler 14, it is located 8,000 light-years away in the Carina Nebula, a huge star-formation region. Because the cluster is only 500,000 years old, it has one of the highest concentrations of massive, luminous stars in the entire Milky Way. (The small, dark knot left of center is a nodule of gas laced with dust, and seen in silhouette.) Diamonds are forever, but these blue-white stars are not. They are burning their hydrogen fuel so ferociously they will explode as supernovae in just a few million years. The combination of outflowing stellar "winds" and, ultimately, supernova blast waves will carve out cavities in nearby clouds of gas and dust. These fireworks will kick-start the beginning of a new generation of stars in an ongoing cycle of star birth and death. http://hubblesite.org/newscenter/archive/releases/2016/03/ Single stars are often overlooked in favour of their larger cosmic cousins — but when they join forces, they create truly breathtaking scenes to rival even the most glowing of nebulae or swirling of galaxies. This NASA/ESA Hubble Space Telescope image features the star cluster Trumpler 14. One of the largest gatherings of hot, massive and bright stars in the Milky Way, this cluster houses some of the most luminous stars in our entire galaxy. Around 1100 open clusters have so far been discovered within the Milky Way, although many more are thought to exist. Trumpler 14 is one of these, located some 8000 light-years away towards the centre of the well-known Carina Nebula. Only within the context of Astronomy, can you call an object, that is appx. 300,000 years old, a "newborn." Yet these are, literally, young, "baby stars." Latest pics from the Hubble telescope. The brightest object in this photo, in the center, is a young star, that is 10,000 times as bright as our sun, and a 1000 times the size. Eventually, gravity will squeeze these newbie stars into a smaller size, and possibly, begin to gather dust and gas, to form planetary discs. GRAVITY- the ultimate CREATOR. Hand of God? Or, simply, a normal event in astronomy. Whatever your side of that argument, a wonder none the less. The brightest diamond in our sky: Stunning Hubble image reveals the biggest and most luminous star cluster in the Milky Way. Known as Trumpler 14, the cluster is 8,000 light-years away in the Carina Nebula, a star-formation region. Cluster is thought to be relatively young at around 500,000 years old, and contains around 2,000 stars.

The new Hubble image depicts the star cluster Trumpler 14, a collection of about 2,000 young stars that lies 8,000 light-years from Earth, near the center of the Carina Nebula. You can zoom in on the glittering star cluster in this stunning video showcasing the new images. This NASA/ESA Hubble Space Telescope image features the star cluster Trumpler 14.

(Hubble is a joint mission involving NASA and ESA.) [Quiz: Take the Hubble Space Telescope Challenge] "These stars are rapidly working their way through their vast supplies of hydrogen, and have only a few million years of life left before they meet a dramatic demise and explode as supernovae," ESA officials added in the statement. The Trumpler 14 cluster is just 500,000 years old, ESA officials said, so many of its stars will live fast and die young. Earth's sun, by comparison, is still ticking along at the ripe old age of 4.6 billion years. The brightest star in the new image is a supergiant called HD 93129Aa, which is about 80 times more massive, and 2.5 million times brighter, than the sun, ESA officials said. HD 93129Aa's surface temperature exceeds 90,000 degrees Fahrenheit (50,000 degrees Celsius), making the star one of the hottest of its type in the galaxy. (For comparison, the sun's surface temperature is about 10,000 degrees F, or 5,500 degrees C.)

4Vikram Posted January 22, 2016 Author Report Posted January 22, 2016 HD 93129Aa is actually part of a binary system; it orbits a common center of mass along with its neighbor HD 93129Ab, ESA officials said. The Hubble Space Telescope launched in April 1990, and astronauts fixed a flaw in its primary mirror during a spacewalk in December 1993. Ever since, the famous observatory has been capturing gorgeous images that have captivated the public and helped to reshape researchers' understanding of the cosmos.
