At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up. Some of the waves - if they have just the right wavelength - combine, increasing in strength, to create a repeating atmospheric heartbeat known as Schumann resonance. This resonance provides a useful tool to analyze Earth's weath...| NASA Scientific Visualization Studio
This page contains equirectangular versions of Perpetual Ocean 2's 'beauty version'.| NASA Scientific Visualization Studio
This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.This visualization was produced using model output from the joint MIT/JPL project: Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2. ECCO2 uses the MIT general circulation model (MITgcm) to synthesize satellite and ...| NASA Scientific Visualization Studio

This is the 'beauty shot version' of Perpetual Ocean 2: Western Boundary Currents. The visualization starts with a rotating globe showing ocean currents. The camera then zooms into the Kuroshio current, moves over the Indian Ocean to the Agulhas Current, then over to the Gulf Stream. The flows from the surface down to 600 meters deep are all white. Flows below 600 meters depth use the blue-cyan-white color table below.| NASA Scientific Visualization Studio
Set to Claude Debussy's Clair de Lune, this visualization uses Lunar Reconnaissance Orbiter data to show the stark beauty of evolving light and shadow near sunrise and sunset on the rugged lunar surface.

A nova is a sudden, short-lived explosion from a compact star not much larger than Earth. The outburst comes from a collapsed star known as a white dwarf, which circles so close to a normal star that a stream of gas flows between them. This gas piles up into a layer on the white dwarf's surface until it reaches a flash point and detonates in a runaway thermonuclear explosion. Astronomers estimate that between 20 and 50 novae occur each year in our galaxy, but despite their power most go undis...| NASA Scientific Visualization Studio
