What Are Gigantic Jets? Understanding the Phenomenon
Defining Gigantic Jets
Gigantic jets are a rare type of transient luminous event (TLE), a family of electrical discharges that occur high above thunderstorms. Unlike typical lightning, which strikes between clouds or to the ground, gigantic jets extend vertically from the tops of thunderclouds, reaching altitudes of 70 kilometers or more into the ionosphere—the electrically charged layer of Earth’s upper atmosphere. These jets are characterized by a bright blue base transitioning to red tendrils at higher altitudes, a result of excited nitrogen and oxygen molecules emitting light at different wavelengths.
The phenomenon begins with intense electrical activity within a thunderstorm, where positive charges accumulate at the cloud top. When this charge overcomes the insulating effect of the lower atmosphere, a powerful discharge surges upward, creating a plasma channel. This process can last mere milliseconds, making gigantic jets challenging to observe without advanced technology. Their rarity—estimated to occur once per thousand thunderstorms—adds to their mystique and scientific value.
How Gigantic Jets Differ from Other TLEs
Gigantic jets belong to a broader category of TLEs, which include sprites, blue jets, and elves. Sprites, the most common TLE, appear as red, jellyfish-like flashes above storms, typically reaching 50–90 kilometers. Blue jets, shorter than gigantic jets, extend up to 40 kilometers and are blue due to nitrogen ionization. Elves, or Emission of Light and Very Low Frequency perturbations, are expansive, ring-shaped glows at 80–100 kilometers. Gigantic jets stand out for their height and the continuous discharge from cloud to ionosphere, distinguishing them as a unique atmospheric event.
The first documented gigantic jet occurred on September 14, 2001, observed by scientists at the Arecibo Observatory in Puerto Rico. Since then, only a few hundred have been recorded, often by chance or with specialized equipment. The July 2025 ISS image marks a significant advancement, capturing the event in unprecedented detail due to recent upgrades to the station’s observation systems.
The Science Behind the Display
The formation of gigantic jets involves complex interactions between thunderstorm electrification and upper-atmospheric physics. Thunderstorms generate electric fields, with positive charges at the top and negative charges below. When the field strength exceeds a critical threshold—often triggered by a strong lightning strike to the ground—a gigantic jet can erupt. This discharge travels at speeds up to 50–100 kilometers per second, ionizing the air and creating a glowing plasma channel.
The blue base of a gigantic jet results from nitrogen molecules emitting light as they lose energy, while the red upper tendrils come from excited oxygen. This color transition reflects the changing atmospheric composition with altitude. Recent research suggests these jets may carry significant electrical energy, potentially influencing the ionosphere’s charge balance—a hypothesis gaining traction after solar storms in May 2025 disrupted satellite signals.
The ISS Capture: A Technological Triumph
The Ax-4 Mission and Observation Upgrades
The image of the gigantic jet was captured by an astronaut from the Ax-4 mission, which launched in June 2025 to study Earth’s atmospheric dynamics from orbit.

These enhancements allow the ISS to detect events like gigantic jets in real-time, transmitting data to ground stations for immediate analysis. The Ax-4 crew, equipped with advanced training in atmospheric observation, played a crucial role in identifying and photographing the jet over the Mexico-U.S. region on July 3, 2025. This marks a significant leap from earlier observations, which relied on sporadic ground-based detections or luck.
The Significance of Space-Based Observation
Observing gigantic jets from space offers advantages over ground-based methods. The ISS’s orbit allows continuous monitoring of storm systems across the globe, capturing events that might otherwise go unnoticed. The July 2025 image, showing the jet’s full extent from cloud top to ionosphere, provides a clearer picture of its structure and energy than previous ground observations, which often missed the upper portions due to atmospheric interference.
Space-based data also enables scientists to correlate gigantic jets with other atmospheric and space weather events, such as solar storms. The May 2025 solar activity, which affected satellite communications, has heightened interest in how TLEs might interact with the ionosphere, a layer critical for GPS and telecommunications. The ISS’s role in this research underscores its value as a platform for Earth science beyond its traditional focus on microgravity experiments.
Challenges in Capturing the Event
Despite technological advances, capturing gigantic jets remains challenging. Their brief duration—lasting only milliseconds—requires precise timing and fast shutter speeds. The ISS’s orbit also means it passes over a given region for just a few minutes, necessitating real-time detection systems to trigger observations. Additionally, the station’s position relative to the Sun and Earth can create glare, complicating imaging during daylight hours. The success of the July 2025 capture highlights the effectiveness of the recent upgrades and the crew’s expertise.
The Connection to Japan’s Megaquake Advisory
The August 2024 Megaquake Warning
In August 2024, Japan’s Meteorological Agency (JMA) issued its first-ever megaquake advisory following a 7.1-magnitude earthquake off Miyazaki Prefecture. This warning, based on seismic data suggesting a potential Nankai Trough megaquake, prompted widespread interest in atmospheric phenomena that might precede or accompany such events.

The advisory highlighted a 75–82% probability of a magnitude 8 or higher quake within 30 years, raising public awareness of natural hazards. This context has fueled speculation about connections between upper-atmospheric lightning and tectonic stress, a theory gaining attention after the July 2025 ISS observation.
Potential Links Between Gigantic Jets and Earthquakes
While no definitive evidence ties gigantic jets to earthquakes, some researchers propose a correlation. Thunderstorms, which spawn gigantic jets, are influenced by atmospheric pressure and temperature changes that might also affect tectonic plates. The electrical energy released by these jets could, in theory, interact with the ionosphere, where changes have been observed before major quakes. The May 2025 solar storms, which disrupted ionospheric conditions, have added urgency to this investigation.
Historical data from the 2011 Tōhoku earthquake, which preceded unusual atmospheric activity, supports this hypothesis. However, the relationship remains speculative, requiring further study. The July 2025 image provides a new dataset to analyze these potential links, bridging atmospheric and seismic research.
