The color of a star is a function of... its surface temperatureshow more

This #FullDiskFriday, we’re showcasing Earth’s land surface temperatures (LSTs)... captured by NOAA's #GOESEast (#GOES19) 🛰️ following a week of extreme heat. GOES-19 used infrared observations to measure LST, but clouds can block its view of the surface. Areas shown in gray indicate where temperature data was unavailable.show more

Robert Kennedy Jr mic drop: "Trusting the experts is... not a function of science. It is not a function of democracy. It is a function of religion and totalitarianism, and it does not make for a healthier population."show more

Differentiation is the study of change. The faster a... function rises or falls, the larger its derivative. As the tangent line flattens, the derivative approaches 0, meaning the function stops changing for an instant. A tangent line follows the direction of the curve. Its slope tells you how the function changes, that slope is the derivative. A new face to my most famous visualization, this time, made with Umbra Beta.show more

🚨: A pulsar spins 716 times per second—its surface... moving at 24% the speed of light. This is a real translation of signals captured by NASA.show more

In 2025, the European ocean region experienced its highest... annual sea surface temperature on record, the 4th consecutive year of record warmth. 36% experienced ‘severe’ or ‘extreme’ conditions. Read the European State of Climate #ESOTC2025:show more

How is it possible that a black hole’s surface... tells us about its interior volume? This finding is a critical clue towards our understanding of the quantum nature of space-time.show more

the inside of the Surface Laptop Ultra is a... work of art 🖼️show more

The Helix Nebula is a planetary nebula formed by... a dying star and is often called the Eye of God because of its striking appearance. 📹 NASAshow more

Stokes' Theorem is a classic result from vector calculus.... It tells us that the line integral of a vector field over a loop is equal to the surface integral of the curl of the vector field over some enclosed surface.show more

Jensen's inequality gives the difference between the average value... of a convex function φ, and its value at the center, where both “average” and “center” are defined in terms of some distribution p_X. When the function φ is flat, or the distribution is narrow, they agree.show more

Alumina aerogel maintains a back surface temperature of just... 39°C (102°F) under dual blowtorches at 1000°C (1832°F) due to its ultra-low thermal conductivity and highly porous, nanostructured aluminum oxide composition.show more

It feels kind of bananas that we can watch... an El Niño forming live as it happens. This is sea surface temperature anomaly data. Keep your eye on the west coast of South America, and how the current on the equator starts by flowing away, but then reverses and flows towards land and builds a bank of hot surface water (yellow).show more

This is a bit freaky. A mysterious light traveling... above the surface of the water.show more

A series of heat waves broke records and is... taking a toll in Europe this summer. This animation shows the daily max surface air temperature across Western Europe from May 1 to Aug. 19, 2026 using the NASA Goddard GEOS model.show more
