In early July 2025, NASA astronaut Nichole “Vapor” Ayers snapped a rare image of a giant red “sprite” phenomenon erupting above a thunderstorm, as she orbited 250 miles (400 km) above Earth. Sprites are brief, luminous columns caused by powerful lightning discharges far below. Ayers noted that having the ISS vantage makes for a “great view above the clouds” and helps scientists analyze these elusive events. This sprite appeared over storm clouds spanning Mexico and the southern U.S. on July 3, 2025. The sighting coincides with NASA’s Spritacular citizen-science project, which crowdsources photos of sprites and other upper-atmosphere flashes.

Rare ‘Sprite’ Phenomenon Explained

According to NASA, sprites are one of the “least understood” and most visually striking upper-atmosphere phenomena. They are brief columns of red light that flash high above thunderclouds, triggered by powerful lightning strikes. Data show sprites often form around 50 miles (80 km) altitude above Earth. These fleeting bursts take varied shapes – tendrils, plumes or towering columns of red light.

In Ayers’s photo, the sprite looks like an inverted scarlet umbrella extending into the sky. Each sprite flash lasts only a few milliseconds, so every image provides valuable data. Observations from orbit and the ground are steadily building a clearer picture of these mysterious storm-driven events. For example, NASA’s Juno mission even recorded sprite-like flares in Jupiter’s atmosphere, suggesting similar lightning processes on other worlds.

Crowdsourcing Sprites

To gather more data on sprites, NASA launched the Spritacular citizen-science project. Through Spritacular, volunteers with cameras can submit photos of upper-atmosphere flashes for research. The project’s website reports over 800 volunteers from 21 countries have uploaded about 360 sprite sightings since its 2022 launch. Each contribution helps scientists map where and how sprites occur. Ayers’s ISS photo adds a valuable perspective that complements citizen reports.

Space.com notes that multiple ISS crew members have begun photographing sprites from orbit, bolstering the data. Spritacular principal investigator Dr. Burcu Kosar says the project “will bridge the gap” between casual observers and researchers. NASA scientists say many questions about how and why sprites form “remain unanswered”, so more images could soon help decode the mystery.

SpaceX’s Starship rocket has scored a landmark success on its 10th test flight. On Aug. 26, 2025, the 400-foot booster launched flawlessly, completed hot-stage separation, and deployed eight dummy Starlink satellites — its first-ever payload. The upper stage then re-entered Earth’s atmosphere, surviving long enough to reignite an engine and splash down in the In…

Astronomers have captured a groundbreaking sight: WISPIT 2b, a baby gas giant planet forming within a dusty, multi-ring protoplanetary disk around a young Sun-like star 430 light-years away. Infrared images from the Very Large Telescope show the planet carving a dark path in the rings as it feeds on gas and dust. This rare discovery provides the first direct evidence …

New ‘Gambling Carnot Engine’ Challenges 200-Year-Old Thermodynamic Law

Published

By

Almost 200 years after the Carnot limit defined the maximum efficiency of heat engines, scientists have introduced a microscopic design that seems to break the rule. Called the “Gambling Carnot Engine,” it works by monitoring a single trapped particle and stepping in at just the right instant. This clever feedback process allows the engine to convert nearly all ab…
