astronomers have combined 7500 single shots of the "Hubble"space telescope to create a panorama image with 265'000 galaxies. The image contains observations from 16 years of age, such as the European "Hubble information centre"in Munich explained.
Some of the galaxies are so far away that their light more than 13 billion years to get to earth. You see in order to a time to when the universe was 0.5 billion years old. Thus, the history of galaxy formation on the basis of the panorama of that time can still be traced today.
"now that we have expanded the view more than in the previous overview images, we harvest much more distant galaxies in the largest such data set ever produced," said the head of the panorama image-team, Garth Illingworth of the University of California in Santa Cruz. "There is no image of this Excel, to future space telescopes such as the James Webb start."
"the Deep Field and Ultra Deep Field"
The Panorama was given the name "Hubble Legacy Field" (about: "Hubble's" legacy section of the Sky) based on three earlier projects in which the space telescope was deeper and deeper into the cosmos looked.
Legendary, the "Hubble Deep Field" – the recording succeeded, in 1995, and shows more than 3000 galaxies. The photographed area is located in a small section of the constellation the Great bear. The edge length corresponds approximately to the angle at which a tennis ball in a hundred meters distance will appear.
in 2004, the "Hubble Ultra Deep Field", which shows 10'000 galaxies, including some of the first created after the big Bang. The exposure time for the shooting amounted to more than eleven days.
can look at 96 percent of the cosmic past
The deeper astronomers into space, the further you can explore the cosmic past. Before the launch of Hubble in 1990, ground-based telescopes would be able to catch a glimpse of galaxies in a maximum of seven billion light-years away, about halfway to the big Bang, explained the information centre. The new "Hubble"-Panorama covers about 96 percent of the cosmic past.
