In the future, we might see one million more satellites in Earth's orbit. The consequences to astronomy would be devastating.
Fighting for a fair and sustainable usage of space, for astronomy and humanity — that's Betty Kioko's job as ESO’s Institutional Affairs Officer.

A new solar system in the making?
Last year, astronomers detected a newborn planet orbiting the star WISPIT 2. After another object was identified near the star, ESO’s Very Large Telescope and the VLT Interferometer confirmed that this was another planet.
This is the second time that multiple planets have been directly observed forming around their host star.

The image was taken with the MUSE instrument at the VLT, which captures a spectrum at every single point within its field of view. In other words: it can image extended regions at thousands of different colours or wavelengths simultaneously, allowing astronomers to map the composition and motion of these regions in great detail.

The Triangulum galaxy up close 👀
Located about 3 million light-years away, this nearby galaxy was captured in the festive-looking image below with ourVery Large Telescope (VLT).
The colours represent different elements: blue, green and red indicate the presence of oxygen, hydrogen and sulphur, respectively. But there's more than meets the eye in this image... 1/

Reflect Orbital and SpaceX have filed proposals with the US Federal Communications Commission that threaten ground-based astronomy. We submitted replies and collaborated with the UK Royal Astronomical Society & the International Astronomical Union for their responses. 1/
Reaching for the stars!
Chilean astrophotographer Alexis Trigo captured the VLT Unit Telescope 4, shooting its laser beams to create artificial stars high up in the atmosphere.
This allows astronomers to correct for atmospheric turbulence that blurs data: https://www.eso.org/public/images/potw2611a/
