O Hubble Space Telescope took a picture containing approximately 5,000 galaxies, the vast majority of which are 11 billion years old. The formation of this “photo” will help astronomers understand the formation of galaxies and the process of their “aging” due to the capture of ultraviolet light.

Class of the year 4 billion photos

It is estimated that age Universe approximately 15.5 billion years, with the first galaxies formed 13 billion years ago – or 2 billion years after birth Universe. To understand the formation of these “old” galaxies, it is necessary to observe the ultraviolet rays emitted by them. However, this “original” radiation is absorbed before it reaches us. And how to get around this problem? searching for galaxies who are also in the “third age”.

With the famous and reliable Hubble Space Telescopeastronomers Mr. Caltech (California Institute of Technology) observed over a period equivalent to 10 days, 140,000 galaxies of various types. Most of them are in the image below, released by a project called UFKANDEL.

“O UFKANDEL gives unique knowledge about learning galaxies near and far [da Terra]”, – said Xin Wang, an astronomer from Caltech responsible for presenting the results of the study at the American Astronomical Society meeting held June 14 in California.

The project is a research sequence

O UFKANDEL is a sequence CANDLES, a project that explored infrared light and the visible spectrum of red. O CANDLES also used Hubble for your comments. Images from the two projects have been combined to form the image featured in this post. This is another study that aims to understand the origin of the universe and the formation of the first stars and galaxies.
