Dusty Belts Provide Clearer Insights into Exoplanet Formation - Eos Millimeter-wavelength observations of dust and pebbles in 74 star systems hint that planetary migrations might be more common than we realized.

74 exocomet belts were found orbiting nearby stars in landmark survey. The observations were made using microwave/millimeter wave telescopes; the resulting images show the belts as bright rings circling the stars at various angles.

A reminder that humans are capable of great acts of wonder when we work together & embrace knowledge.

An international team of astronomers has discovered swarms of cold comets circling 74 nearby stars -- and got clear pictures of these "exocomet belts." 🧪🔭

Astrophysicists led by a team from @tcddublin.bsky.social have imaged a large number of exocomet belts around nearby stars, observing where ice reservoirs of planetary systems are located. Read on @siliconrepublic.bsky.social here: siliconrepublic.com/innovation/reasons-trinity-exocomets-research

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.

A nearly terrestrial D/H for comet 67P/Churyumov-Gerasimenko Analysis of Rosetta measurements suggests that Jupiter family comets could have delivered much of Earth’s water.
