3/1/2024 0 Comments Hubble pictures*The higher resolution, black & white Hubble image and the lower resolution, color CTIO images were combined using a technique that takes luminosity (brightness) information from the black and white ACS image and color information from the composite CTIO image. The color results from assigning different hues (colors) to each monochromatic image. In total, three filters were used to sample narrow wavelength emission. This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope along with ground-based observations. HST>ACS, CTIO>4m Blanco Telescope and CTIO>MOSAIC2 Walawender (Institute for Astronomy/University of Hawaii). Bally (University of Colorado at Boulder), and J. Smith (University of California, Berkeley), J. *A small area of the Hubble ACS image that was saturated around the brightest star in the field, Eta Carinae, was replaced with images from previous shorter exposures from Hubble's Wide Field Planetary Camera 2. Bally (University of Colorado at Boulder), N. The ACS data was from the HST proposal 10241 : N. This color image combines many exposures from Hubble Space Telescope's Advanced Camera for Surveys (ACS)* and NOAO/AURA/NSF Cerro-Tololo Interamerican Observatory's (CTIO) 4m Blanco Telescope and MOSAIC2 camera. This image is roughy 25 arcminutes (53 light-years or 16 parsecs) wide.

Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.ĬreditsHubble Image: NASA, ESA, N. Color information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. The Hubble images were taken in the light of neutral hydrogen. This image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology). In looking at the Carina Nebula we are seeing the genesis of star making as it commonly occurs along the dense spiral arms of a galaxy. Our Sun and our solar system may have been born inside such a cosmic crucible 4.6 billion years ago. This is triggering a second stage of new star formation. The hurricane blast of stellar winds and blistering ultraviolet radiation within the cavity is now compressing the surrounding walls of cold hydrogen. The island-like clumps of dark clouds scattered across the nebula are nodules of dust and gas that are resisting being eaten away by photoionization. Radiation from these stars carved out an expanding bubble of hot gas. The fireworks in the Carina region started three million years ago when the nebula's first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen. Eta Carinae is in the final stages of its brief and eruptive lifespan, as evidenced by two billowing lobes of gas and dust that presage its upcoming explosion as a titanic supernova. The most unique and opulent inhabitant is the star Eta Carinae, at far left. The immense nebula contains at least a dozen brilliant stars that are roughly estimated to be at least 50 to 100 times the mass of our Sun. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. Hubble's view of the nebula shows star birth in a new level of detail. It is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth - and death - is taking place. In celebration of the 17th anniversary of the launch and deployment of NASA's Hubble Space Telescope, a team of astronomers is releasing one of the largest panoramic images ever taken with Hubble's cameras.
