Photo of the day: NASA showed the most detailed photo of the universe
NASA needed 16 years to do this photo. It took so long to collect data from the Hubble Space Telescope to create his greatest work: the most accurate photo of the universe ever created.
There is a type of night pictures that have always affected my imagination more than others. These are photographs with the visible Milky Way. Such a picture can be taken only at a large distance from cities where there is no so-called light pollution .
A magnificent strip of stars showing the cross-section of our galaxy shows that we all live on the outskirts of the galaxy, far from the center.
A photo showing a part of our galaxy can amaze you. Meanwhile, the latest NASA photograph shows ... 265 thousand. galaxies on one shot.
Hubble Legacy Field is a photography that was created for 16 years and consists of 7500 individual photos taken by the Hubble telescope. As we see objects from different distances in one photo, photography is also the most complete history of the universe we have ever been able to portray.
The oldest galaxies visible in the photo are in fact a picture from before 13.3 billion years, so we observe them in the state in which they occurred only 500 million years after the big explosion.
The farthest galaxies are completely invisible to humans. They reach in the sky a brightness of only one ten-billion level of brightness that an unarmored human eye can catch.
The NASA picture is so complex that it is difficult to assess its resolution.
The resolution of this photo is not uniform. In the picture there are areas more deeply examined by the Hubble telescope, and in them there is an area in which the telescope has bitten in the deepest way, ie XDF (eXtreme Deep Field). The level of complexity is shown by the animation prepared by NASA.

This huge amount of data is just a very narrow section of the universe.
Number 265 thousand The galaxies sound completely unimaginable, but the most shocking is the information about what part of the sky we are actually watching.
The entire Hubble Legacy Field image includes a slice comparable to the size of the Moon seen from the surface of the Earth. If we realize how small the object is the Moon in the background of the whole sky, we can quickly conclude that we do not really know anything about our universe.
