NASA Science

Astronauts saw flashes on the Moon. So did volunteers on Earth. Now, it’s your turn. 🌙 If you have a telescope, you can help NASA study lunar impacts… and even future moonquakes: go.nasa.gov/4uaqW1r

You don’t have to go to space to help humans thrive there. NASA citizen science volunteers support research on astronaut health, space weather, and even growing food for future missions. No experience needed, just curiosity. Learn more: go.nasa.gov/4sYSuG8

When Typhoon Sinlaku struck the Northern Mariana Islands, the storm destroyed the tools to track it. Data from @NASA and its partners filled in the gap, providing critical rainfall measurements to emergency responders.

🚀 Inspired by Artemis II? The science behind missions like this depends on sharing data, tools, and ideas openly. Learn how to make your own research more transparent, accessible, and impactful with NASA’s free Open Science courses: go.nasa.gov/4uo232D

NISAR sees subtle changes in Earth’s land and ice surfaces. But how does it work? The SAR in NISAR stands for synthetic aperture radar, and it helps scientists “see” through clouds to track changes in cities, forests, and ice.

It’s Citizen Science Month! Citizen scientists, people just like you, have helped @NASA learn more about our universe since the agency began! Ready to do some science? We’ll take you on a tour of some of the projects that have data waiting to be analyzed by volunteers. ⬇️

Happening today ☄️ Join our Do NASA Science Live virtual event: Comets, Clues, and Our Cosmic Story Meet the scientist behind Rubin Comet Catchers and take part in the research live – scanning real observatory images to help identify hidden comets. Live at 6pm and 9pm ET. Register: go.nasa.gov/4mGFnrr

Scientists are studying how the gut microbiome changes in space! 🦠 CBIOMES just wrapped up aboard the space station, and the results could help us improve methods to protect astronaut gut health on future space missions.

Next-generation missions to explore destinations like Mars may need to operate autonomously. An onboard operations agent that can detect events and determine spacecraft actions in real time without human input was demonstrated on NASA’s MMS mission. go.nasa.gov/4tLmBCk

From Hubble discoveries to your screen. 👇 You can do NASA science, too. With Galaxy Zoo, volunteers classify @NASAWebb galaxies – sometimes as the first humans to see them.  👀 Get started: science.nasa.gov/citizen-scienc…

New views of Earth from (s)PACE 🛰️ Artemis II captured stunning views of our home planet, but did you know NASA has a whole fleet of satellites studying Earth ? This view comes from PACE, which studies Earth’s ocean and atmosphere.

Can’t get enough of space? Meet the scientist behind Rubin Comet Catchers and scan real observatory images to help identify hidden comets during our next Do NASA Science Live virtual event. 📆 Wednesday, April 29 🔗 Register: go.nasa.gov/3QM5mSr

The Sun emitted two strong solar flares, the first peaking at 9:07pm ET on April 23 and the second peaking at 4:13am ET on April 24. NASA’s Solar Dynamics Observatory captured images of the events, which were classified as X2.4 and X2.5: go.nasa.gov/4sPr45D Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such space weather may affect Earth, check out @NWSSWPC, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts.

Low-cost sensors can help fill important gaps in air quality monitoring. A new dataset harmonizes ground-based measurements from inexpensive sensor networks around the world, helping researchers compare, validate, and expand pollution studies: go.nasa.gov/3QgWapb

Fly along with @NASAEarth's missions...right from your browser. Eyes on the Earth brings satellites, data, and global events together in an interactive 3D view of our planet. go.nasa.gov/4cSVWNE

Our oasis in space 🌎💙 Seeing Earth from this unique perspective reminds us how special our home planet is. Download the 2026 Earth Day poster for a daily dose of inspiration: go.nasa.gov/3QVD5ZG

Calling all Earth data users! 🌎 Join NASA’s Satellite Needs Working Group Implementation Team (NSITE) May 12-13 for a virtual Harmonized Landsat and Sentinel-2 (HLS) workshop. Explore applications, recent updates, and future plans for HLS. Details: go.nasa.gov/4tPiC79

From the first awe-inspiring views of Earth from lunar orbit in 1968 to today’s cutting-edge satellite technology, and Artemis II, we’ve never stopped expanding how we see our home planet. With every mission, we’re discovering something new about the planet we call home and our place within the universe.

The next delivery of NASA science and equipment to the @Space_Station is set for no earlier than May 12. In addition to experiments, these resupply missions also bring supplies that allow the crew aboard to continue living and working in low Earth orbit: go.nasa.gov/3Qe8wyp

This #EarthDay we're inviting you to do science with us! 🌍🐾 Join today’s Do NASA Science Live: Earth Day Animal Spot‑a‑Thon! Explore trail camera images and help identify wildlife, supporting real research on how animal populations are changing. 🔗 Register: go.nasa.gov/4sE6BAk
