ESOs GIGAGALAXY ZOOM: The Sky, from the Eye to the Telescope
Through three giant images, the GIGAGALAXY ZOOM project reveals the full sky as it appears with the unaided eye from one of the darkest deserts on Earth, then zooms in on a rich region of the Milky Way using a hobby telescope, and finally uses the power of a professional telescope to reveal the details of an iconic nebula.
In the framework of the International Year of Astronomy 2009 (IYA2009), ESO has launched a new project aimed at connecting the sky as seen by the unaided eye with that seen by hobby and professional astronomers. The project, called GIGAGALAXY ZOOM, reveals three amazing, ultra-high-resolution images of the night sky that online stargazers can zoom in on and explore in an incredible level of detail.
The GIGAGALAXY ZOOM project thus illustrates the vision of IYA2009, which is to help people rediscover their place in the Universe through the day- and night-time sky.
