@NASA 🔎 If you look even closer, there's even a brief spotting of comet 3I/ATLAS along the way!

Comet SWAN is on the move. ☄️ Captured by @NASA's PUNCH spacecraft, comet 2025 R2 (SWAN) can be seen moving away from the Sun as the solar wind blows its tail away, creating the illusion that the comet is “moving backward.” 🔗: https://t.co/GMmjGjHr1s

BREAKING: Sugars essential for life have been found in pristine asteroid Bennu samples collected by NASA’s OSIRIS-REx spacecraft. Combined with previous detections of amino acids and nucleobases, we see that life’s ingredients were widespread throughout the solar system:
