Hail yes! 🌧️🧊 See hail in your backyard? Report it and help NASA study how hail melts. Your observations make real science possible! Join: go.nasa.gov/41hpgqu

When severe storms hit, every minute matters. 🌩️🌍 After last year’s Southeast storms (100+ tornado reports), NASA used AI to detect key storm features, helping map impacts and support response efforts. Learn how NASA is turning satellite data into action: go.nasa.gov/4byDjg1

Some regions on the Sun stay active for months... and they may produce far more solar flares than expected. Using data from this citizen science project, researchers found these long-lived regions are 3–6× more likely to produce the Sun’s most powerful flares: go.nasa.gov/4sSx9yw

#MeteorSighting: A very bright daylight fireball was observed by witnesses from the northeast U.S. and Canada this morning, March 17. An analysis of currently available data places first visibility of the meteor above Lake Erie. The fireball - caused by a small asteroid nearly 6 feet in diameter and weighing about 7 tons - moved southeast at 45,000 mph before fragmenting over Valley City. The fragments continued on to the south, producing meteorites in the vicinity of Medina County, Ohio. 🔗 go.nasa.gov/4bcMwMg Eyewitness accounts supplied by the American Meteor Society

When OSIRIS-REx reached the asteroid Bennu in 2018, scientists expected to find a smooth, beach-like surface. Instead, they encountered a jagged, rugged world. Samples of the asteroid, brought back to Earth in 2023, are helping untangle the mystery: go.nasa.gov/4cMGBPb

NASA’s Parker Solar Probe just did it again. ☀️ On March 11th, it completed its 27th close approach to the Sun, flying just 3.8 million miles from the solar surface at a blistering and record-matching 430,000 mph. New data drops March 18: go.nasa.gov/474BFBH

What happens when microscopic life goes to space? NASA volunteers studied biofilms, layers of microbes that live together on surfaces, to see how they adapt to spaceflight. The results could help support astronaut and plant health on future missions: go.nasa.gov/4rDrMSX

@AsleepThe84357 Well said! 🤝

@NASAScience_ This is the power of Citizen Science! It’s so inspiring to see how professional researchers and volunteer astronomers can team up to track planetary defense. Science truly belongs to everyone.

NASA used a spacecraft to hit an asteroid. Now scientists have discovered the impact altered the orbit of that entire asteroid system around the Sun. Discover how they measured this tiny change with help from volunteer astronomers around the world: go.nasa.gov/4uqwl5w

Galaxies leave clues when they collide. Tails, shells, and faint streams of stars reveal past encounters, and Euclid telescope images are uncovering them in stunning detail. You can help scientists spot these cosmic signatures with Galaxy Zoo: Tidal Tales: go.nasa.gov/4b9QvcA

Our Eye on Mars 🔴 As it marks 20 years at the Red Planet, here are five ways @NASA's Mars Reconnaissance Orbiter (MRO) is mapping the future of exploration. 🛰 ➠ 👩‍🚀 🧵 1/6

NASA‑sponsored researchers have created new electronics that can survive extreme radiation and temperatures. This breakthrough could enable the next generation of robotic explorers and support sustainable human outposts on the Moon and Mars. 🔗 go.nasa.gov/4liI9Tc

Everyone is buzzing about the Moon! This month’s featured image is a breathtaking view from the Lunar Reconnaissance Orbiter: the western wall of an unnamed lunar crater glowing in morning sunlight, casting long, dramatic shadows across the surface: go.nasa.gov/46RqxIa

How much do rivers rise and fall during a year? New data from the joint NASA and CNES SWOT mission suggests that Earth's rivers don't change as much over the course of a year as previously thought. Read more: go.nasa.gov/3Noo4hL

Allow us to reintroduce ourselves… The Nancy Grace Roman Space Telescope is @NASA’s next space observatory, set to launch as early as fall 2026. Named after NASA’s first chief astronomer, #NASARoman will have a field of view at least 100 times larger than @NASAHubble. This field of view will help us better understand many cosmic mysteries including dark matter and dark energy. It will revolutionize our understanding of the universe by revealing countless cosmic objects, from stars and planets to galaxies and black holes. The telescope will be heading a million miles away to Lagrange point 2 along with fellow telescope, @NASAWebb. Check out nasa.gov/roman to stay up to date on the mission!

What's up for March? The Moon will appear red during a total lunar eclipse on March 3. On the 8th, Venus and Saturn snuggle close in the night sky. Plus, March 20 is the first day of spring in the Northern Hemisphere. More: science.nasa.gov/solar-system/w…

New skill unlocked! 🔓 NASA’s PACE satellite, known for measuring tiny ocean organisms and particles in the atmosphere, has a new ability: it can track nitrogen dioxide, a harmful air pollutant. go.nasa.gov/3ZZ9U9B

Giant tortoises are returning to the wild on Floreana Island in the Galápagos for the first time in over 150 years. Conservation teams used @NASA satellite data to help choose release sites where the animals can find food, water, and nesting areas. go.nasa.gov/3MDcK11
