NGC 1269
The Cosmic Steering Wheel NGC 1269
This Image of the Week of NGC 1269 was taken utilizing the Department of Energy-fabricated Dark Energy Camera (DECam), which is mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at NSF Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. NGC 1269...
Central Molecular Zone
Location of the Central Molecular Zone in the Milky Way
This image shows the location of the Central Molecular Zone (CMZ), a region at the core of our galaxy rich in dense and intricate gas clouds. This zone has been mapped with the Atacama Large Millimeter/submillimeter Array (ALMA), as part of the ALMA CMZ Exploration Survey or ACES. The inset is...
Central Molecular Zone
Largest ALMA image ever shows the molecular gas in the centre of the Milky Way
This image shows the complex distribution of molecular gas in the Central Molecular Zone (CMZ) of the Milky Way. It was obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner. This map is as long as three full Moons side-by-side in the sky, and it is in...
Central Molecular Zone
Different molecules in the centre of the Milky Way observed with ALMA
This montage shows the distribution of different molecules in the Central Molecular Zone (CMZ) of the Milky Way. The observations were made with the Atacama Large Millimeter/submillimeter Array (ALMA), as part of the ALMA CMZ Exploration Survey or ACES. ACES has mapped the distribution of...

Chamaeleon Infrared Nebula
A wide-field view of the area around the Chamaeleon Infrared Nebula.

Two's company
We humans are strongly influenced by the presence of companions over the course of our lives, shaping each other emotionally, culturally, or intellectually. This shaping effect is made literal in the case of stellar companions, which is the topic of today's Picture of the Week. The pair of...
1RXS J052832.5+283824
VLT image of a dead star creating a shock wave as it moves through space
The central square image, taken with the MUSE instrument on ESO’s Very Large Telescope, shows shock waves around the dead star RXJ0528+2838. When a star moves through space it can push away nearby material creating a so-called bow shock, which in this image is glowing in red, green and blue....
1RXS J052832.5+283824
Wide-field view (PanSTARRS) of the area of the sky around the star RXJ0528+2838
This image from the PanSTARRS survey shows the region of the sky around the dead star RXJ0528+2838, which is located at the very centre of the image.
1RXS J052832.5+283824
Wide-field view (DSS) of the area of the sky around the star RXJ0528+2838
This image from the Digitized Sky Survey (DSS) shows the region of the sky around the dead star RXJ0528+2838, which is located at the very centre of the image.

The precious rings of space
Not all rings are forged in fantasy, my precious! For astronomers, they are found in space. The ones in today’s Picture of the Week are debris discs: the leftovers of planet formation around other stars. Even our Solar System has a debris disc, known as the Kuiper Belt, where numerous asteroids...
Ve 7–27
Young or old? — There’s both
Today’s Picture of the Week represents an unexpected full circle moment. The depicted object, known as Ve 7–27, was long believed to be a planetary nebula — the end phase of a sun-like star’s life. But ESO’s Very Large Telescope (VLT) has shown that it’s actually a still-forming baby star. ...
SVS 13
Young stars blow bubbles?
We know that a star’s childhood is turbulent: growing via a disc of gas and dust, the same disc from which planets form. Young stars also experience outbursts, expelling material via fast jets that regulate how much material is left to feed the young stars and form planets around it. Today’s...

3C 321: Galaxy Fires at Neighboring Galaxy
This composite image shows the jet from a black hole at the center of a galaxy striking the edge of another galaxy, the first time such an interaction has been found. In the image, data from several wavelengths have been combined. X-rays from Chandra (colored purple), optical and ultraviolet...
