NASA citizen scientists collected thousands of photographs and temperature readings that are being used to study the relationship between total solar eclipses and clouds.
NASA satellites are helping track tiger habitat, offering hope and new insights for conservation as these predators face the consequences of rapid habitat loss.
These maps depict how much hotter or cooler an ocean basin was compared to the long-term average. Temperature anomalies can indicate changes in ocean circulation or the arrival of patterns like El Niño and La Niña.
Net radiation is the balance between incoming and outgoing energy at the top of the atmosphere. It is the total energy available to influence climate after light and heat are reflected, absorbed, or emitted by clouds and land.
These maps depict anomalies in land surface temperatures (LSTs); that is, how much hotter or cooler a region was compared to the long-term average. LST anomalies can indicate heat waves or cold spells.
Satellite images of Earth at night have been a curiosity for the public and a tool of fundamental research for at least 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness.
When fuels such as coal, wood, and oil burn incompletely, they produce carbon monoxide. The gas is spread by winds and circulation. These maps show monthly averages of CO in the lower atmosphere.
Have you ever wondered what it would be like to live in a different part of the world? What would the weather be like? What kinds of animals would you see? Which plants live there? By investigating these questions, you are learning about biomes.
Airborne aerosols can cause or prevent cloud formation and harm human health. These maps depict aerosol concentrations in the air based on how the tiny particles reflect or absorb visible and infrared light.
Sea salt, volcanic ash, dust, wildfire smoke, and industrial pollution are types of airborne aerosols. Natural aerosols tend to be larger than human-made aerosols. These maps show when and where aerosols come from nature, humans, or both.
In honor of our site anniversary, we offer a selection of some of the most beautiful, newsworthy, interesting, and scientifically important images from 23 years online — one image for each day of the calendar year.
