NOAA One year ago, solar storms lit up the night sky. Why?
The Sun is 93 million miles away from Earth, on average. Even though it’s far away, we can still see and feel its effects here. One of the most beautiful effects are the auroras – colorful lights that dance across the sky near the North and South Poles. These are also called the Northern and Southern Lights. They happen when tiny particles from the Sun hit gas molecules in our atmosphere and give off energy.
Sometimes the Sun becomes very active and sends out a lot more energy than normal. When this happens, we can see auroras in places much farther from the poles than normal. In May 2024, around Mother’s Day, the Sun sent powerful solar storms in the direction of Earth. These storms were also called the Gannon Storms, named after Jennifer Gannon, a scientist who studied space weather. The Northern Lights could be seen as far south as Puerto Rico, Hawaii, Mexico, Jamaica, and the Bahamas. The Southern Lights were also visible as far north as South Africa and New Zealand.

Their studies of the Sun have shown that it goes through cycles of being more active and less active. Each one of these cycles lasts about 11 years, but can be anywhere from 8 to 14 years long. This is called the Solar Cycle.
The middle of each cycle is called Solar Maximum. During this time, the Sun has more dark spots (called sunspots) and creates more space weather events. The big storms in May 2024 happened during the Solar Maximum for Solar Cycle 25.
On May 8 and 9, 2024, an active area on the Sun called AR3664 shot out powerful solar flares and several huge bursts of energy called coronal mass ejections (CMEs). These CMEs headed straight for Earth. The first CME pushed aside the normal solar wind, making a clear path for the others to reach us faster. When all this energy hit our atmosphere, it created auroras much farther from the poles than usual. It was like the Sun gave the auroras a huge power boost!

These types of eruptions often come just before a larger Coronal Mass Ejection (CME), including the ones which caused the Mother’s Day solar storms. NASA/SDO Auroras are beautiful to watch, but the space weather that creates them can also cause problems. Space weather can mess up radio signals, power grids, GPS systems, and satellites. During the May 2024 storms, GPS systems used by farmers were disrupted. Many farmers use GPS to guide their self-driving tractors. Since this happened during peak planting season, it may have cost billions of dollars in lost profit.
Because space weather can cause so many problems, scientists at NASA and around the world watch the Sun closely to predict when these events will happen. You can help too! Join local science projects at schools, teach others about the Sun, and help make observations in your area. All of this helps us to learn more about the Sun and how it affects our planet.
Here are some resources to connect you to the Sun and auroras
Lesson Plans & Educator Guides
Magnetic Mysteries: Sun-Earth Interactions
A 5E lesson for high school students to investigate the question of what causes aurora by using Helioviewer to examine solar activity.

Former Johnson Director Jefferson Howell July 3, 2025
Jefferson Davis Howell, Jr., former director of NASA’s Johnson Space Center in Houston, died July 2, in Bee Cave, Texas. He was 85 years old.
Howell was a champion of the construction of the International Space Station, working on a deadline to complete the orbiting lab by 2004. He oversaw four space shuttle crews delivering equipment and hardware to reach that goal. He also served as director during a pivotal moment for the agency: the loss of STS-107 and the crew of space shuttle Columbia. He made it his personal responsibility to meet with the families, look after them, and attend memorial services, all while keeping the families informed of the accident investigation as it unfolded.
“Gen. Howell led NASA Johnson through one of the most difficult chapters in our history, following the loss of Columbia and her crew,” said acting associate administrator Vanessa Wyche. “He brought strength and steady direction, guiding the workforce with clarity and compassion. He cared deeply for the people behind the mission and shared his leadership skills generously with the team. We extend our heartfelt condolences to his family and all who knew and loved him.”
At the time of his selection as director, he was serving as senior vice president with Science Applications International Corporation (SAIC) as the program manager for the safety, reliability, and quality assurance contract at Johnson. Following the accident, he made it his mission to improve the relationship between the civil servant and contractor workforce. He left his position and the agency, in October 2005, shortly after the Return-to-Flight mission of STS-114.
“General Howell stepped into leadership at Johnson during a pivotal time, as the International Space Station was just beginning to take shape. He led and supported NASA’s successes not only in space but here on the ground — helping to strengthen the center’s culture and offering guidance through both triumph and tragedy,” said Steve Koerner, Johnson Space Center’s acting director. “On behalf of NASA’s Johnson Space Center, we offer our deepest sympathies to his family, friends, and all those who had the privilege of working alongside him. The impact of his legacy will continue to shape Johnson for decades to come.”
The Victoria, Texas, native was a retired lieutenant general in the U.S. Marine Corps with a decorated military career prior to his service at NASA. He flew more than 300 combat missions in Vietnam and Thailand.
Howell is survived by his wife Janel and two children. A tree dedication will be held at NASA Johnson’s memorial grove in the coming year.

Astronomers using the European Space Agency’s Cheops mission have caught an exoplanet that seems to be triggering flares of radiation from the star it orbits. These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year.
This is the first-ever evidence for a ‘planet with a death wish’. Though it was theorised to be possible since the nineties, the flares seen in this research are around 100 times more energetic than expected.
