Big Telescope Gives Best-Ever 3D View Of Deep Space
But if you were wowed by the Hubble Deep Field–and the similar Hubble Deep Field South (HDFS) image of 1998–you should know that a telescope in northern Chile has outdone Hubble. It’s given astronomers what’s being called the best-ever three-dimensional view of the deep universe.
(Story continues below images.)
The background image in this composite shows the Hubble Space Telescope image of the region known as the Hubble Deep Field South. The boxes show distant galaxies that were invisible to Hubble.
In this picture, white star symbols are faint stars in the Milky Way. Everything else is a distant galaxy. Circles show objects that appear in the Hubble Deep Field South image. Triangles represent the newly observed objects: blue objects are comparatively close, green and yellow ones more distant, and purple and pink galaxies are seen when the universe was less than one billion years old.
