3/ At the centre of the Tarantula Nebula, the VLTI/GRAVITY+ observed the binary star in the inset below.
This object was originally thought to be an extremely massive star. Yet the new observations reveal its true binary nature, showcasing the stunning capabilities of the upgraded VLTI.

2/ As part of the GRAVITY+ commissioning activities, the VLTI observed the Tarantula Nebula.
The four lasers created a bright fake star in the atmosphere, 90 km above Earth’s surface and visible in the image below.

Black hole outflows from Centaurus A detected with APEX
Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimetre wavelengths for the first time. The new data, from the Atacama Pathfinder Experiment (APEX) telescope in Chile, which is operated by ESO, have been combined with visible and X-ray wavelengths to produce this striking new image.

The first test observations (using a technical camera in the device that will align the telescope mirrors) are planned for 2029. The first observations with the scientific instruments themselves are planned for 2030.
