The Hubble telescope offers an even deeper view of the universe.



  The depth image of the Hubble telescope is even more amazing!

One of the Hubble Space Telescope's most famous images peered deeper into the cosmos than the scientists had imagined.

That The photo is the Hubble Ultra-Deep Field (HUDF), which combines hundreds of images taken by the Space Telescope over several years into the deepest view of the universe. The composite image of a small patch of sky contains a whopping 10,000 galaxies, astronomers have estimated. (The HUDF also refers to this sky, not just pictures.)

Now the researchers have painstakingly processed the iconic image and gained much extra light, a new study reports. [The Most Amazing Hubble Space Telescope Discoveries!]

"What we have done is to enhance the archive of the original images, which is directly observed by the HST, and to improve the combination process, whereby the best image quality is not only aimed for the distant smaller galaxies, but also for the extended regions of the largest galaxies, "said study leader Alejandro Borlaff from the Instituto de Astrofísica de Canarias (IAC) in the Canary Islands in a statement.

The new work revealed that some of the galaxies in the HUDF view are almost twice as large as previously assumed, said members of the study team.

The Hubble Space Telescope launched into orbit in April 1990 aboard the NASA Space Shuttle Discovery. The scope had an unfavorable start; The first images were blurry, a problem that led the members of the mission team back to a small flaw in Hubble's main mirror.

Spacewalk astronauts resolved this issue in December 1993, giving Hubble the sharp focus for which he is known today.

The most recent of them, which took place in May 2009, installed Hubble's current focus on the Universe, an instrument known as the Wide Field Camera 3 (WFC3).

The HUDF image has been in the works for a long time. The first version combines the data collected by Hubble from the end of 2003 to the beginning of 2004. later updates include additional images in different wavelengths of light.

The new study, published this month in the journal Astronomy & Astrophysics, looked at the incarnation of the 2012 HUDF, which relied heavily on the WFC3 data.
