Hubble reports a record number of 265,000 galaxies in one image | NOW

Astronomers have captured a record 265,000 galaxies in one image. The picture was drawn using observations made by the Hubble space telescope over the last sixteen years. Dutch astronomers Rychard Bouwens and Marijn Franx from Leiden University also contributed to the creation of the picture.

The Hubble Legacy Field includes galaxies of up to 500 million years after the Big Bang. The weakest and brightest systems have a brilliance of ten billion of what the human eye can see.

The picture contains nearly 7,500 individual shots. Previously, Hubble's view focused on a small area in the air for a total of 250 days.

According to Bouwens, who also works at Leiden Observatory, Hubble can observe so many galaxies through the "number of sensitive color channels that are now available to observe distant galaxies, especially in the ultraviolet part of the spectrum".

This means that astronomers can differ better with old and new stars.

The project relies on earlier Hubble observations

In the past, astronomers have already produced an image of this kind of galaxies many times, and each time the Hubble looked deeper into the universe, and with it further into the past. .

It began in 1995 with the Hubble Deep Field project, where thousands of previously unknown were captured in one image.

Hubble Ultra Deep Field continued in 2004 with a photograph taken in 1995 and managed to capture some ten thousand systems in one image. Hubble Field then took Deep eXtreme over in 2012, and the Hubble stayed in the same area in the universe for ten years.

The new picture of the Legacy Field Hubble contains the above images again. The team is now working on a second image, which will include more than 5,200 Hubble images.
