The Sun and Our Lives
On a clear night, you might see thousands of stars in the sky. Most of these stars are dozens or hundreds of light years away from us. A light year is the distance a beam of light travels in a year: about 5.88 trillion miles (9.46 trillion kilometers). This means that for those stars we see at night, it takes their light, which travels at about 186,000 miles per second (or about 300 thousand kilometers per second), dozens or hundreds of years to reach us.
But in the daytime, we only see one star: the Sun. It dominates the daytime sky because it is so close – about 93 million miles (or 150 million kilometers) away. That distance is also called one astronomical unit, and its another unit of measurement astronomers use to record distance in space. But even if 1 astronomical unit seems like a long way, it’s still about 270 thousand times closer than Alpha Centauri, the next nearest star system.
The Sun isn’t just close – it’s also gigantic! The Sun is large enough to fit more than a million Earths inside it, and has more mass than 330 thousand Earths put together. Its light also provides the energy which allows life as we know it to flourish. For these reasons, the Sun is a powerful presence in our lives. We all have a relationship with the Sun, so knowing about it, and about the benefits and hazards of its presence, is essential.
Teaching About the Sun
Autumn is when most students in the United States return for a new school year after summer vacation. This back-to-school time offers a wonderful opportunity to reach students fresh off of a few months of fun in the Sun and capture their imaginations with new information about how our native star works and how it impacts their lives.
To that end, NASA conducts efforts to educate and inform students and educators about the Sun, its features, and the ways it impacts our lives. NASA’s Heliophysics Education Activation Team (HEAT) teaches people of all ages about the Sun, covering everything from how to safely view an eclipse to how to mitigate the effects of geomagnetic storms.

This often means tailoring lesson plans for educators. By connecting NASA scientists who study Heliophysics with education specialists who align the material to K-12 content standards, HEAT gets Heliophysics out of the lab and into the classroom. Making Sun science accessible lets learners of all ages and backgrounds get involved in and excited about the discovery, and instills a lifelong thirst for knowledge that builds the next generation of scientists.
Since 2007, NASA’s Living With a Star (LWS) program and the University Corporation for Atmospheric Research’s Cooperative Programs for the Advancement of Earth System Science (CPAESS) have cooperated to offer the Heliophysics Summer School program for doctoral students and postdoctoral scholars. This program aims to foster heliophysics as an integrated science, teaching a new generation of researchers to engage in cross-disciplinary communication while they are still in the early days of their career.
One Way to Get Involved
As part of its efforts to increase awareness of the scientific and social importance of heliophysics, and to both inspire future scientists and spark breakthroughs in heliophysics as a discipline, the NASA Heliophysics Education Activation Team (NASA HEAT) is working on a slate of educational materials designed to get students involved with real-world mission data.
My NASA Data, in collaboration with NASA HEAT, has released a new set of resources for educators centered around space weather. My NASA Data supports the use of authentic NASA data as part of classroom learning materials. These materials include lesson plans, mini-lessons (shorter activities for quick engagement), student-facing web-based interactives, and a longer “story map,” which deepens the investigation of the phenomenon over multiple class periods.
These resources are designed to engage learners with data and observations collected during both past and ongoing missions, including the European Space Agency’s Solar Orbiter, NASA’s Parker Solar Probe and Solar Dynamics Observatory (SDO), and more.
One example of this is the educational material published to support outreach efforts focusing on the 2023 and 2024 American solar eclipses. These materials allowed learners to collect their own data on cloud and temperature observations during the eclipses with the GLOBE Observer Eclipse tool. This gave them the chance to participate in the scientific process by contributing meaningfully to our understanding of the Earth system and global environment.
New Ways to Engage
Groups like HEAT don’t just spark interest in science for the sake of inspiring the next generation of heliophysicists. Just like amateur astronomers can bring in a lot more data than their professional counterparts, citizen scientists can do a lot to support the same institutions that may have inspired them to take up the practice of citizen science. This can mean anything from helping to track sunspots to reporting on the effects of space weather events.
These enthusiasts are also adept at sharing knowledge of heliophysics. Even just one person inspired to buy a telescope with the right solar filter (international standard ISO 12312-2), set it up in a park, and teach their neighbors about the Sun can do amazing work, and there are a lot more of them than there are professional scientists. That means these amateur heliophysicists can reach farther than even the best official outreach.
Whether they take place in the classroom, at conferences, or in online lectures, the efforts of science communicators are a vital part of the work done at NASA. Just as scientists make new discoveries, these writers, teachers, audio and video producers, and outreach specialists are passionate about making those discoveries accessible to the public.
All of this work helps to inspire the scientists of tomorrow, and to instill wonder in the citizen scientists of today. The Sun is a constant and magnificent presence in our lives, and it offers plenty of reasons to be inspired, both now and in the future.
