Research shows that during total solar eclipses, some animals change their behavior to match their nighttime activities.

Solar eclipses are a cosmic coincidence because the moon is 400 times smaller than the sun but about 400 times closer to Earth, allowing it to block sunlight for those on Earth within its shadow.

Visualize the path of every solar eclipse from 1900 to 2099 and see what each looks like when observed from different locations on Earth.

Aurora-related activities drive significant tourism in regions near the Arctic Circle

As the peak solar cycle approached from late 2024 to early 2026, airlines serving countries such as Iceland, Finland, and Canada increased their scheduled flights, with direct flights to Tromsø, Norway, doubling since 2018. The northern lights tourism market has grown about 10% per year and is expected to increase from $941.9M in 2024 to $1.648B in 2030.

In 2024, 332 million visitors to America's national parks spent an estimated $29B in local surrounding economies.

Electric grids that rely on solar power must compensate for reduced electricity generation during solar eclipses.

Some maps may incorrectly identify the boundaries of a solar eclipse's totality because they assume the Earth is a smooth surface.

Every eclipse is preceded or followed by another eclipse, separated by about two weeks and alternating between solar and lunar types.

Eclipse glasses protect the eyes from overexposure to the sun's ultraviolet, blue, and infrared light, as a person's instinct to look away from the sun is diminished when it's partly blocked.

Because the half of Earth that faces the sun is larger than the area of the shadow cast by the moon during a solar eclipse, observers may experience a total, annular, or partial eclipse.

The Lunar New Year is a major driver in China's economy

The annual festival brings in billions of dollars in both foreign and domestic tourism. The 2026 holiday includes an additional day, something Chinese officials hope will provide an even bigger boost to the country's somewhat stubborn national retail sales.

Over thousands of years, the frequency of solar eclipses is greatest around the Arctic and Antarctic Circles and lowest near the equator.

Rare chance for US states to see Northern Lights

A solar storm in July 2023 offered people in 17 American states, as well as Canada, an unusual chance to witness the Northern Lights, or aurora borealis. The 11-year solar cycle, reaching its peak in 2024, made the lights visible in places further south than usual. Read up on the announcement from the Geophysical Institute at the University of Alaska at Fairbanks here.

The Eras Tour generated $2B in ticket sales, but $5B in consumer spending

Taylor Swift has achieved such high-profile status, her music and tours influence a broad swath of industries, communities, and economies. “Swiftonomics” is the term used to describe how Taylor’s tours, merchandise sales, and brand boost everything from local business receipts to tourism in a community.

Just as directly observing a solar eclipse without protective glasses can cause permanent eye damage, photographing an eclipse requires a specialized filter to prevent damaging your camera.

Taylor Swift's Eras tour was the first tour ever to gross over $1B, and caused the Federal Reserve to acknowledge its impact on regional economies.

While the sun, moon, and stars rise and set from east to west due to Earth's rotation, the moon's eastward revolution around the Earth causes its shadow to move from west to east during a solar eclipse.

The first scientifically useful photograph of a total solar eclipse was taken in Königsberg, Prussia, on July 28, 1851, using a silver-coated copper plate with a light-sensitive chemical layer.

Americans spent nearly $150B in sports-related bets in 2024

These bets ranged from who would win the World Series to what color clothes famous celebrities would wear to the Super Bowl. Experts believe the industry will continue to grow.

Because the retina lacks pain receptors, during a solar eclipse, those watching without protective eyewear may suffer from permanent damage without realizing it.

NASA economic impact (and budget history)

It's estimated that for every dollar NASA spends on its programs, $8 is produced in US economic growth. With a 2023 budget of roughly $25 billion, that means NASA helped create $200 billion in economic value. The administration's investments pay off so massively due to the technologies it develops, many of which become commercially appealing. Dive into the economic impact of NASA's development here.

In 2025, the European Space Agency created the first artificial solar eclipse in space when one spacecraft cast a shadow onto another spacecraft to enable observations of the sun's outermost atmosphere.

Enough sunlight hits Earth in just 90 minutes to power the planet for an entire year

Despite this, in 2023, only 5.1% of electricity in the US came from solar energy. Solar panel technology has nonetheless made significant advancements since the 19th century, largely due to NASA's efforts in the space race.

Although the moon passes between the sun and Earth each month, its orbit is tilted by five degrees, preventing Earth from experiencing a solar eclipse each month.

View US solar energy industry trends and trajectories, tracked by SEIA

The Solar Energy Industries Association provides charts summarizing the state of solar energy in the US, including cumulative solar installations, solar jobs, photovoltaic pricing and deployment, and inflation and supply chain constraints within the market.

Scientists validated Albert Einstein's theory of gravity by measuring the apparent positions of stars via their starlight as it traveled near the sun on its way to Earth during a total solar eclipse.

Blood moons only occur during total lunar eclipses, when the Earth blocks the sun, but its atmosphere lets redder parts of sunlight through to reflect off the lunar surface.

A solar eclipse viewer can be made from everyday objects, such as a cereal box, aluminum foil, tape, and paper, to safely view the cosmic event.

Explore global solar resources with this interactive map

One of the biggest challenges to deploying solar panels is whether electricity can be generated reliably when needed, day after day. This detailed interactive map calculates the solar power output potential of regions worldwide and provides a visual comparison between locations such as North Africa and the US Midwest.

CES has brought more than $6B in economic impact to Las Vegas since 1978

Since moving to Las Vegas in 1978, CES has attracted nearly 5 million attendees and generated more than $6B in local economic impact—boosting hotels, restaurants, transportation, and the city’s global profile.

The impacts of the solar maximum on Earth, from telecommunications to auroras

During the peak of the sun's 11-year cycle, plasma emissions stronger than the average stream of particles from the sun can compress and distort the Earth's magnetic field, allowing auroras to be seen farther from the poles. Distortions in the ionized layer of Earth's atmosphere can also alter the path of communication transmissions through the air. (Some readers may experience a paywall.)

Comic-Con generates over $165M for the San Diego economy each year

San Diego’s community gets a significant boost from Comic‑Con, which draws around 135,000 attendees annually. It generates over $165M in regional spending—with more than $90M coming directly from visitors—and adds approximately $3.2M in city tax revenue.

The majority of exoplanets—planets outside the solar system—have been discovered through mini-eclipses created when they pass in front of their host star and block some of its light from reaching Earth.

US holiday retail sales reached $973B in 2024

In 2024, US holiday retail sales reached $973B—nearly one-fifth of annual sales. Many companies depend on this season to bolster revenues.
