Low Ice in the Gulf of St. Lawrence

The body of water off eastern Canada is one of the southernmost locations where Arctic sea ice forms, but its extent in winter 2024-2025 was well below normal.

World of Change

NASA satellites document how our world—forests, oceans, human landscapes, even the Sun—changes over months, seasons, and years.

Sea Surface Temperature Anomaly

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.

Total Rainfall

These maps depict monthly total rainfall around the world. Rainfall is the primary source of fresh water for humans, plants, and animals. Rain also moves heat between the atmosphere, oceans, and land.

Earth at Night

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.

How to Interpret a Satellite Image: Five Tips and Strategies

What do you do when presented with a new satellite image? Here's what the Earth Observatory team does to understand the view.

2024 North Atlantic Hurricane Season

Hurricane season in the basin runs from June 1 to November 30.

Renewable and Alternative Energy

People have developed systems to harvest and store energy from sources such as wind, sunlight, and tidal action. Many of these installations are visible from orbit.

Land Human Presence

Snow Cover

Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month.

Land Surface Temperature Anomaly

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.

Chlorophyll

Chlorophyll is used by algae and other phytoplankton--the grass of the sea--to convert sunlight and carbon dioxide into sugars. These maps show chlorophyll concentrations in the ocean, revealing where phytoplankton are thriving.
