A1689-zD1: Astronomers Find Highly Evolved Galaxy in Early Universe

This spectacular view from the Hubble Space Telescope shows the galaxy cluster Abell 1689. The galaxy A1689-zD1 is located in the box, although it is still so faint that it is barely seen in this picture. Image credit: NASA / ESA / L. Bradley, Johns Hopkins University / R.

An international team of scientists, headed by Dr Darach Watson of the University of Copenhagen in Denmark, has used the X-ray instrument on ESO’s Very Large Telescope along with the Atacama Large Millimeter/submillimeter Array to observe A1689-zD1 – one of the youngest and most distant galaxies ever found. The extremely distant galaxy A1689-zD1 appears on this picture as the elongated reddish object; its light has been magnified by a factor...

The background image in this composite shows the Hubble image of the region known as the Hubble Deep Field South. New observations using VLT’s MUSE instrument have detected remote galaxies that are not visible to Hubble; two examples are highlighted in this composite view; these objects are completely invisible in the Hubble picture but show up strongly in the appropriate parts of the three-dimensional MUSE data.

Comparing Hubble images of the gas-and-dust disk encircling the young star Beta Pictoris taken in 1997 and 2012, astronomers find that the dust distribution has barely changed over 15 years despite the fact that the entire structure is orbiting the star like a carousel.

Resembling looming rain clouds on a stormy day, dark lanes of dust crisscross the giant elliptical galaxy NGC 5128, also known as Centaurus A. The warped shape of NGC 5128’s disk of gas and dust is evidence for a past collision and merger with another galaxy. The resulting shockwaves cause hydrogen gas clouds to compress, triggering a firestorm of new star formation. At a distance of just over 11 million light-years, NGC 5128 contains the closest active galactic nucleus to Earth. The center is home for a supermassive black hole that ejects jets of high-speed gas into space, but neither the supermassive black hole or the jets are visible in this image.
