Our next guest for #AskAstrobio is Dr. Penny Boston, a pioneer in astrobiology exploration of unique and diverse cave systems all over the world. What type of cave system do YOU think is most important for informing our search for life beyond Earth? Vote: youtube.com/channel/UC14eJ…

NASA science, but make it EXTREME 🤯 As part of the PACE-PAX field campaign, pilots flew the NASA Armstrong ER-2 upwards of 63,000 feet high to help calibrate and validate data from the PACE satellite. To do so, they wear pressurized suits and eat and drink through a tube!

A new NASA study shows ferns may help plants and animals recover in damaged landscapes, playing a key role in ecosystem recovery after major disasters. First appearing 360 million years ago, ferns were once Earth's most common vascular plants. go.nasa.gov/3BHC2FI

Asteroid Bennu’s parent body was likely a salty, wet environment – one surprisingly like a lakebed on Earth. NASA scientists drew similarities between a sample collected from Bennu by the #OSIRISREx mission & minerals from Searles Lake, a dry lake in California’s Mojave Desert.

Where is air pollution most potent? What is the electromagnetic charge of thunder clouds? How do ecosystems recover after a wildfire? These are some questions scientists have explored through our Airborne Science Program.✈️ Happy National Science Day! airbornescience.nasa.gov

The dinosaurs went extinct because they didn't have a space program. But we do. Our newest documentary, "Planetary Defenders," shows how we find, track, and mitigate asteroids. Available now in its entirety on X.

The Moon's Gruithuisen Domes, shown here, are comparable to volcanic formations in Katmai National Park. This same region on Earth is also home to Mars-like terrain. Many geologic features & processes are common throughout our solar system. Compare worlds: go.nasa.gov/3BtmpPh

To confirm the correlation between tree leaf color and CO2 from volcanic magma, scientists measured CO2 levels and collected leaf samples near an active volcano in Costa Rica. 🌴🌳 The research was with AVUELO, a joint NASA and Smithsonian field campaign, in March 2025.
