Earthset captured through the Orion spacecraft window at 6:41 p.m. EDT, April 6, 2026, during the Artemis II crew’s flyby of the Moon. A muted blue Earth with bright white clouds sets behind the cratered lunar surface. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region.  In the foreground, Ohm crater has terraced edges and a flat floor interrupted by central peaks. Central peaks form in complex craters when the lunar surface, liquefied on impact, splashes upwards during the crater’s formation.

All the news today caused the major outlets to forget that we are taking the first human flight to the moon tomorrow in >50 years! I think about all the wonder & inspiration that came from the Apollo and Voyager missions & how we are missing that now bc of all the terrible things happening. 🔭🚀

Happy vernal equinox! You may know this as one of 2 dates when the day and night are roughly equal length, or as the beginning of spring in the northern hemisphere and fall in the southern.

But to astronomers, the vernal equinox has an additional fun significance... 🧪🔭 (1/8)

My 1st first-author paper has been submitted to ApJL and is available on arXiv!

We found that elevated water vapor abundances in Mars-like exoplanet atmospheres suppress abiotic oxygen accumulation via CO2 photolysis by an order of magnitude relative to past studies. 🧪🔭🪐
