A very hungry planet! 🪐
What appears to be a ripple in space is actually a newborn planet, eating its way through its dusty cradle around a younger version of our Sun 🌞

The NASA/ESA/CSA James Webb Space Telescope has found evidence of a cold, Saturn-mass planet around the star TWA 7, seemingly sculpting its disc of debris!
If confirmed, this would be Webb’s first direct image discovery of a planet.

World's darkest and clearest skies at risk from industrial megaproject
On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.

The skies above Paranal are at risk from a proposed industrial megaproject.
This would be located in the vicinity of ESO's Observatory. If constructed, it would irreparably impact astronomical observations.

Using JWST, a team of researchers including scientists from ULiège has succeeded in measuring the isotopes of ammonia in the atmosphere of a cold brown dwarf. This study shows that the isotopic abundance of ammonia can be used to study gas giant formation. www.psilab.uliege.be/cms/c_120604...
