One of the most iconic images of the Hubble Space Telescope is the Hubble Ultra Deep Field, a view of thousands of galaxies in all shapes, sizes and colors. The Hubble team released a deeper version in 2012 . What's next? Going deeper.

On Thursday, a research team from Spain's Instituto de Astrofísica de Canarias published what they call "the deepest image of the universe ever taken out of space". It looks very different from previous Hubble shots.

This new take on Hubble's deep image draws new light from dark galaxies.

The original Ultra-Deep-Field image from 2004 is described as a "deep" core sample of the universe that goes through billions of light-years.

Image processing technology enhancements helped researchers create the new, more detailed look that shows masses of gray areas that were previously dark in the Hubble version of 2012. This deeper viewing highlights distant areas of space that were previously invisible.

The team worked from hundreds of original Hubble observations, working the combined views to recover a large amount of light [emitted by stars] from the outer zones of the largest galaxies. " The senior researcher Alejandro Borlaff tweeted that the team discovered thousands of millions of hidden stars.

The work of the Instituto de Astrofísica de Canarias is discussed in an article published in the journal Astronomy & Astrophysics. The researchers provide their findings and data to other scientists online via a website called ABYSS HUDF WFC3 / IR Project.

For the casual observer, the new Ultra Deep Field looks like a mess, but Instituto de Astrofísica de Canarias says the recovered light has already shown that some of the galaxies in the image are nearly twice the diameter of those measured previously.

Hubble is a joint project of NASA and the European Space Agency. The telescope had some technical difficulties during its lifetime but the space agencies hope that will continue until 2025 .

NASA turns 60: The space agency has conquered humanity further than anyone else, and there are plans to go further.

It goes to extremes: mix insane situations – erupting volcanoes, meltdowns, 30-foot waves – with everyday technology. The following happens:
