Science in pictures

Look closely at the structures, scales and natural events that scientists observe—from cellular processes and animal behavior to atmospheric systems, ice and nanoscale engineering.

These archive selections pair memorable scientific subjects with short, accessible explanations. Some entries document past image contests; others examine one striking observation in detail.

About this collection

Reading a scientific image

A compelling picture can make an unfamiliar scale or process easier to approach, but the image is only the beginning. Captions, methods and context explain what was recorded and what conclusions the evidence supports.

Notice the scale

Ask whether the view is microscopic, human-sized, landscape-scale or planetary.

Identify the method

Photography, microscopy, satellite sensing and data mapping reveal different kinds of information.

Check the color

Some colors are natural; others are added to distinguish structures or represent measurements.

Read the limits

One image can illustrate an observation without proving every proposed explanation.

Frequently asked questions

What kinds of images are in this archive?

The collection includes scientific photography, microscope imagery, satellite views, maps and visual explanations of natural phenomena.

Are all colors in scientific images natural?

No. Researchers sometimes assign colors to wavelengths, measurements or structures that would otherwise be difficult or impossible for human eyes to distinguish.

Why does scale matter?

Scale determines what an image can show. A cellular view, weather image and satellite landscape each represent very different dimensions and evidence.

Are the image contests still accepting submissions?

No. The contest pages in this collection are retained as historical archive material; their original submission periods have ended.

How should older visual stories be used?

Use them for foundational context and historical perspective. Consult current specialist sources if a decision depends on recent measurements or research.
