Up Mauna Kea with on a comet mission. The green glow of C/2025 R2 (SWAN) cutting through the Milky Way. Discovered just last month by the SWAN instrument aboard SOHO, this comet made its closest pass to Earth in mid October, about 39 million km away. The emerald color comes from diatomic carbon gas glowing under solar radiation a signature of comets born far beyond the planets.

Lava islands in the middle of a raging lava river! What a sight to see multiple still islands of hardened lava rock surrounded by fast flowing molten lava.

What an absolute pleasure it was to go behind the scenes at the Keck Observatory and learn about the incredible technology that powers this world class telescope. Seeing its sodium wavelength lasers in action was nothing short of awe inspiring, and it was fascinating to witness how all the systems work together to capture data that helps astrophysicists unlock new insights about our universe.
