On July 3, 2025, NASA astronaut Nichole Ayers aboard the International Space Station (ISS) captured an awe-inspiring phenomenon that has fascinated scientists and skywatchers alike: a red sprite. These fleeting, upward-moving electrical discharges—often described as red jellyfish lightning—were observed over a massive thunderstorm system stretching from Mexico to California. The event, which lasted only a few milliseconds, represents the mysterious beauty of Earth’s upper atmosphere and gives us new insights into atmospheric processes that are rarely seen by the naked eye.

The breathtaking red sprite phenomenon, captured by NASA astronaut Nichole Ayers, is more than a mesmerizing image—it’s a heartfelt invitation to marvel at the wonders of Earth’s upper atmosphere and deepen our connection to our planet. These rare and beautiful events offer vital insights into the intricate electrical processes, space weather, and global atmospheric systems that sustain life. By sharing this discovery, we foster a collective sense of awe and responsibility, inspiring communities worldwide to cherish and protect the delicate balance of our shared home.
As technology advances, we’ll continue to explore the relationship between thunderstorms and upper-atmospheric events like red sprites, enhancing our understanding of the natural world and space exploration. Just as the ancestors used the stars to guide them, we too can look to the sky to uncover the secrets hidden in its mysterious light.
What Are Red Sprites?
1. Understanding Red Sprites
Red sprites are a type of transient luminous event (TLE) that occurs high above thunderstorms in the mesosphere, the region of the atmosphere between 30 to 50 miles above Earth’s surface. Unlike typical lightning that strikes downward, red sprites shoot upward, and their glow is often described as looking like a jellyfish with tendrils radiating downward.
These phenomena are usually brief and occur less than 10 milliseconds. Despite their brief appearance, they hold valuable information about Earth’s electrical systems, including the dynamics of lightning and high-altitude electrical discharges.
2. Characteristics of Red Sprites
Red sprites are often red or orange in color due to the excitation of nitrogen molecules in the upper atmosphere. This chemical reaction occurs when high-energy electrical discharges travel through the ionosphere. In addition to their red glow, red sprites may have bright, tendril-like shapes, making them appear somewhat like jellyfish.
Red Sprites and Scientific Significance
1. Studying Earth’s Upper Atmosphere
Red sprites are essential for understanding electrical processes that occur at high altitudes. While most studies focus on thunderstorms and lightning within the lower atmosphere, sprites provide an opportunity to investigate the mesosphere, which is otherwise difficult to access. Their occurrence offers insights into how electrical energy is transferred in Earth’s atmosphere and how it may affect space weather and communications.
2. Space Weather and Communications
Red sprites, along with other TLEs such as blue jets and ELVES, can affect radio communications and satellite operations. The electrical discharges created by these phenomena can impact long-range communication systems, especially those using low-frequency radio waves. As space weather events like these become more understood, scientists can develop more accurate predictive models to mitigate their effects on our modern technologies.
The ISS: A Unique Perspective
1. Capturing the Unseen
The International Space Station provides astronauts with a unique vantage point to observe and capture phenomena like red sprites. From its orbit, astronauts can observe the upper atmosphere of Earth without the interference of the lower layers of the atmosphere. This makes the ISS an ideal platform for studying high-altitude atmospheric events and gaining insights into the behavior of lightning and electrical discharges that are difficult to observe from the ground.
2. NASA’s Role in Scientific Discovery
NASA’s collaboration with astronauts aboard the ISS allows scientists to gather real-time data from space-based platforms. These observations help scientists create models that explain space weather and its impacts on both communication technologies and global weather patterns.
Link to Cultural Significance: Lightning in Indigenous Traditions
In many Native American cultures, lightning and thunder are seen as powerful forces that connect the Earth to the spirit world. Thunderbirds, often depicted as giant birds or eagles, are believed to control lightning and bring storms. Similarly, sprites—with their electric energy and fleeting nature—might be seen as messengers from the spirit world, bringing both destruction and renewal.
For example:
- The Navajo associate lightning with the Thunder Beings, who are integral to creation stories and the natural balance of the world.
- The Lakota view lightning as a sign of spiritual power and renewal, representing both danger and purification.
By studying these phenomena scientifically, we may also gain a deeper spiritual understanding of the forces at work in the natural world.

Astronaut Captures Rare ‘Red Jellyfish’ Lightning Observe Red Sprites
For sky enthusiasts who want to try observing red sprites, here’s a step-by-step guide:
1. The Best Time to Observe
Red sprites are most commonly observed during strong thunderstorms that generate significant lightning activity. The best time to spot them is when thunderstorms are particularly active over areas like mountainous regions or coastal areas, where the upper atmosphere is more likely to exhibit TLEs.
2. What You’ll Need
- A Telescope or Binoculars: Though red sprites are usually not visible with the naked eye, they can be detected with high-speed cameras or telescopes.
- High-Speed Cameras: These are essential for capturing the brief nature of the phenomenon. Professional skywatchers and scientists use high-frame-rate cameras to capture TLEs.
- Knowledge of Thunderstorm Locations: Use websites like EarthSky or NOAA to track thunderstorms in your area or globally.
3. Safety Tips
As red sprites occur in the upper atmosphere, they don’t pose any danger to people on the ground. However, if you are tracking storms, stay safe during lightning by avoiding outdoor activities during thunderstorms.
Red Sprites and Space Research: Beyond Earth
The observation of red sprites is more than a mere scientific curiosity; it holds significant space exploration value. As humanity moves toward sending manned missions to Mars and beyond, understanding space weather—including TLEs like red sprites—becomes crucial.
For future astronauts, high-altitude electrical discharges could pose potential risks to their health and communication systems. Understanding how these phenomena interact with spacecraft will be key to ensuring safe travel and operations beyond Earth.
FAQs
