A collection of educational resources and links to the websites of international research centers and space missions, that teachers and educators may find useful:



NSO Stem Box

Browse and download lessons, activities, and more from these categories: Electromagnetic Spectrum, Optics, Solar science, space weather, and Sun/Earth connections.


The project Sun4All allows students to work with real solar images and accomplish scientific results. Sun4All proposes 7 different activities using digitized solar images, for different ranges of ages - from the simple counting of sunspots to an elaborate determination of the solar rotation period.

Sunspotter Citizen Science Project

The Sunspotter project aims to construct a reliable measure of sunspot group complexity. It is primarily a science project but also offers students a great way to contribute to current cutting-edge research.


NASA Sun as a Star

The Sun As a Star activities teach concepts related to the sun with opportunities for the students to investigate each idea. Most of the nine sequential activities can be completed in about one hour.


Journey to the Sun (NSO)

The JTTS curriculum consists of 6 ready-to-implement lesson packages. Each package contains a slideshow presentation, a teacher's guide, and corresponding activities. (NSO is responsible for DKIST, our sister solar telescope, currently under construction in Hawaii).

NASA Goddard Media Studios: SDO

Pictures, movies, and infographics explaining different aspects of solar physic research can be found in this collection prepared by NASA's Scientific Visualization Studio using SDO observations. 

NASA Goddard Media Studios: Parker Solar Probe

Launched in 2018, Parker Solar Probe is providing new data on solar activity and making critical contributions to our ability to forecast major space-weather events that impact life on Earth.

TRACE Educational Resources

This site offers tools to learn more about the Sun and the TRACE mission. You'll find some basic information here, as well as links to other sites on the web that contain more detailed explanations of solar physics topics.

Stanford Solar Center

History, culture, art and different resources on solar physics and solar research for teachers, students and the general public.

Yohkoh Public Outeach Project

The Yohkoh Movie Theater (YPOP) is designed to bring you images and movies depicting our nearest star, the Sun, as seen by an X-ray telescope that was carried on board the Yohkoh satellite. The YPOP site includes a range of activities for youngsters, parents, teachers and anyone interested in learning more about the Sun.

SOHO Clasroom

Activities and resources for students and teachers, based on the data, history, science and mission of the Solar and Heliospheric Observatory.

The Light Tour (Science Education Gateway)

A self-tutorial that introduces the electromagnetic spectrum through the concepts of wavelength and amplitude. Students learn to associate various wavelength ranges with different spectral bands, and can explore images from space astronomy missions in each band.


Helioviewer is an open-source tool for the visualization of solar and heliospheric data. It is part of the Helioviewer Project, funded by ESA and NASA.



History of Solar Physics

HAO offers interesting resources on the history of solar physics, including 'A History of famous Solar Physicists', 'Solar Physics Historical Timeline', and 'Solar Astronomy in the Prehistoric Southwest'.
