La brillante tapisserie de jeunes étoiles qui prennent vie ressemble à un feu d'artifice scintillant dans l'25 image du télescope spatial Hubble de la NASA pour commémorer un quart de siècle d'exploration du système solaire et au-delà depuis son lancement le 24 avril 1990.'Hubble a complètement transformé notre vision de l'univers'', a déclaré John Grunsfeld, astronaute et administrateur associé de la Direction de la mission scientifique de la NASA. « Cette vue de feux d'artifice étoilés et de gaz incandescent est une image digne de notre célébration de 25 ans d'étonnante science Hubble.

The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in the 25th anniversary NASA Hubble Space Telescope image to commemorate a quarter century of exploring the solar system and beyond since its launch on April 24, 1990.'Hubble has completely transformed our view of the universe, '' said John Grunsfeld, astronaut and associate administrator of NASA's Science Mission Directorate. 'This vista of starry fireworks and glowing gas is a fitting image for our celebration of 25 years of amazing Hubble science.'The sparkling centerpiece of Hubble's silver anniversary fireworks is a giant cluster of about 3, 000 stars called Westerlund 2, named for Swedish astronomer Bengt Westerlund, who discovered the grouping in the 1960s. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20, 000 light-years away from Earth in the constellation Carina.To capture this image, Hubble's Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery in near-infrared light, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between 6 to 13 light-years across.The giant star cluster is only about 2 million years old and contains some of our galaxy's hottest, brightest, and most massive stars. Some of its heftiest stars unleash torrents of ultraviolet light and hurricane-force winds of charged particles that etch at the enveloping hydrogen gas cloud.The nebula reveals a fantasy landscape of pillars, ridges, and valleys. The pillars, composed of dense gas and thought to be incubators for new stars, are a few light-years tall and point to the central star cluster. Other dense regions surround the pillars, including reddish-brown filaments of gas and dust.The brilliant stars sculpt the gaseous terrain of the nebula and help create a successive generation of baby stars. When the stellar winds hit dense walls of gas, the shockwaves may spark
