«I believe that scientific knowledge has fractal properties, that no matter how much we learn, whatever is left, however small it may seem, is just as infinitely complex as the whole was to start with» — Isaac Asimov (I Asimov, 1995)

In weightlessness, water can take forms that are not possible under normal gravitational conditions. One example being thin sheets, 500 microns thick, formed in a wire loop like in a soap film but here as pure water with no surfactant.

As air flows around iced wings ✈️🧊 Using NASA’s LAVA framework, engineers created this simulation of air flowing around ice buildup on a Common Research Model wing, helping predict how ice formation could impact aircraft performance.

Small but mighty 💪 Using scientific instruments on a high-altitude plane, @NASA and @NOAA scientists are studying the role that tiny particles — 6 millionths of an inch across or smaller — play in the chemistry of Earth’s atmosphere.

You can't spell discovery without "disco" 50 years ago today, NASA launched a 2-foot (60-cm) ball that transformed studies of Earth’s shape, rotation, and gravity field. It has no sensors, no batteries, no electronics… just 426 retroreflectors that allow scientists to make extremely precise distance measurements using lasers. LAGEOS is still orbiting Earth, and is expected to remain in its very stable orbit for millions of years!

Nice catch, @astro_reid! From our shared legacy of almost 26 years of a continuous human presence conducting science and technology demonstrations on the @Space_Station to the successful return to the Moon with the Artemis II mission, all of us at @NASA are so excited to have entered the @NASAArtemis era. We explore together as one humankind.

Each second, the Sun blasts about 1.5 million tons of matter into space at speeds of hundreds of miles per second, while Earth’s magnetic field shields the planet from this solar wind. 🎥 : NASA Goddard

Annie Easley, born OTD in 1933, began her career at the NACA (NASA's predecessor) in 1955 as a “human computer.” When machines began to replace human computers for performing complex calculations, Easley adapted, becoming an expert computer programmer. Easley's 34-year career at NASA furthered research on alternative power and technology on the Centaur rocket.

Here’s a multi-wavelength view of tonight’s X2.5-class #SolarFlare. This is the strongest flare we’ve seen for 78 days.

Our first rocket has launched! 🚀 Elaine Ho, Associate Administrator for NASA’s Office of STEM Engagement, pressed the ignition button to launch James Madison University’s rocket here at our 2026 Student Launch challenge. Watch here: youtube.com/live/m1yg865Mt…

Flashlights and lasers in space? 💥 During a solar flyby, NASA’s Parker Solar Probe made a surprising discovery about high-speed particles accelerated by explosive events on the Sun: Protons spread out like a flashlight beam 🔦 Heavy ions shoot out straight like a laser ⚡ This unexpected data is hinting at the power source behind solar storms that disrupt tech on Earth.

#ICYMI: @NorthropGrumman’s Cygnus XL cargo craft, packed with quantum physics gear, a new blood stem cell study, an advanced exercise system, and more for the Exp 74 crew, was captured with the Canadarm2 robotic arm at 1:20 p.m. EDT on Monday, April 13, 2026.
