MICHELLE STARR 25 JAN 2019
A few years ago, the Hubble Space Telescope did something amazing: over the course of 841 orbits and hundreds of exposures, it imaged a tiny region of space in the constellation of Fornax, peeling back the layers of time by 13 billion years, to just a few hundred million years after the Big Bang.
It's called the Hubble Ultra-Deep Field 2014 (HUDF), and it's one of the most breathtaking mosaics the telescope has produced. In it, around 10,000 galaxies gleam - a feast for astronomers exploring the early Universe.
Now a team of astronomers has made the image even better. Over the course of three years, scientists at the Instituto de Astrofísica de Canarias (IAC) developed and applied an image processing technique designed to draw out the unseen light in the HUDF.
They called this complex technique ABYSS, and with it they have recovered the dim light from the outer edges of the largest galaxies in the image.

(1,533 posts)The technique was applied around the largest galaxies, kind of taking away the glare. An actually working technique like the broadcast TV commercials for sunglasses. You know, where the "actual people, not paid actors" are amazed and simply stunned by how well the sunglasses work...

(18,693 posts)Knowing there were so many galaxies found in that small segment of the universe expanded my own view of our incredible existence.
Having read Carl Sagan's book Cosmos twice back in the day I finally had a visual understanding of how there can be "more stars in the universe than there are grains of sand on every beach on Earth". That seemed like so much hyperbole when I first read that line.
It's amazing that the Hubble can hold steady for a time exposure long enough to make these bodies appear like magic. Imagine what the next generation space telescope will do. Or we can waste money on Space Force just so we can plant a flag in geosync orbit.
Thanx for posting!

Thanx for asking.
