4 events that dazzled skygazers in 2024, from total solar eclipse to northern lights (2025)

Every year, anything from dazzling meteor showers to bright, full moons reliably give stargazers plenty of reasons to regularly look up at the cosmos.

But in 2024, observers were treated to their fair share of celestial shows that were anything but ordinary. This year was one filled with astral displays that defied expectations and filled us here on Earth with a sense of wonder and awe about the universe that surrounds us.

And thanks to the power of modern cell phones, that cosmic majesty is becoming easier to see and appreciate – even for those unable to witness the sights in person.

Here's a recap of some of the most notable celestial events of the year, from the total solar eclipse to the proliferating northern lights.

Total solar eclipse dazzles millions across North America

When you think about celestial events in 2024, no other cosmic display will come as close to defining the year as the total solar eclipse.

The eclipse, a once-in-a-lifetime event, completely put to shame its North American predecessor from 2017 when it charted a 115-mile-wide path across Mexico, the United States and Canada.

Why? The sun's outermost layer, the elusive corona, was brighter, the moon appeared larger and the uncharacteristic darkness known as totality lasted just a bit longer. What's more, millions of spectators in 13 states had a front row seat to witness the eclipse's majesty.

Few celestial events have the ability to capture our collective attention. But for a few brief minutes when totality reached various cities across the U.S., schools let out, work came to a pause and people across the nation took a moment to take in the sight.

The awe-inspiring spectacle is a rarity – and will become even more so in the years ahead. While only seven years passed between total solar eclipses in North America, the next one visible in the continent won't be until 2044.

'Devil Comet' makes itself visible to naked eye

The total solar eclipse is a tough act to follow, but later in the same month, the recognizable "devil comet" did its best.

The horned comet with a demonic nickname made itself visible in April to ground observers without telescopes.

The famed "devil comet," officially known as12P/Pons-Brooks, on April 21 made it closest approach to the sun in its 71-year orbit of the massive star.

Earning its nickname from its distinctive tail that resembles horns, the comet has also been likened to the Millennium Falcon spaceshipfrom "Star Wars." While "the Devil Comet" is typically visible to only those with the strongest of telescopes, on the day it's closest to the sun, its brightness increased so much that astronomers predicted it would be visible to the naked eye.

Harvest supermoon combines with partial lunar eclipse

Aspectacular lunar eventdazzled skygazers Sept. 17 across the United States and the entire Northern Hemisphere.

The Harvest Moon, which has inspired no shortage of cultural touchstones – froma Nintendo gameto Neil Young’sBillboard hit– occurs annually around the start of fall at a time when Earth's only natural satellite is especially close to our planet. But this year's full Harvest Moon, which also just so happened to be an exceptionally large and bright supermoon, another phenomenon occurred: a partial lunar eclipse.

On that night, the orange-huedHarvest supermoon rose in the skyat a time when Earth's only natural satellite was unusually close to our planet on its elliptical orbit. Then, hours later, the moon waspartly covered by Earth's shadowas our planet moved between it and the sun.

Striking images from across the world captured the spectacular sight, including not only the Harvest supermoon, but also the moment whenthe partial lunar eclipseoccurred.

Northern lights activity on rise amid solar maximum

The aurora borealis, a natural light display in Earth's sky famously best seen near our planet's poles, spent 2024 cropping up in a wider swath of the northern hemisphere.

The phenomenon, better known as the northern lights, surfaced with increased frequency amid the approach of the solar maximum.

That was most evidentin May when apowerful geomagnetic stormunleashedspectacular viewsof the northern lightsin parts of the country where auroras are not often visible. On the downside, that solar storm was also responsible for some reports of power gridirregularities and interference with GPS signals – evenfarming equipment.

That particularstorm watchwas the first NOAA released in 19 years for a geomagnetic storm classified as a G4 – a single level away from being the most severe solar storm possible. Amid the solar activity, the sun even emittedan explosive burst of radiationthat became thelargest solar flaredetected since 2017, according tothe NOAA.

The auroras were alsonotably visible again in Augustduring thePerseids, considered among astronomers to bethe best meteor shower of the year.

Then in October, Americans from the northern U.S. and even as far south as Alabama once againhad a chance to witnessthestriking rays, spirals and flickers of the northern lights, which was amplified when a solar coronal mass ejection of plasma clouds and charged particles drove a geomagnetic storm toward Earth. The storm was so strong that it prompted NOAA toissue another rare G4 geomagnetic storm watch.

Now thatthe sun is officially at the height of its 11-year cycle, the increase in solar activity will more frequently fuel "space weather"that produces the right conditions for northern lightsto flourish.

That means, in the months ahead, the famed celestial display could be coming to asky near you– if it hasn't already.
