Stunning Southern Lights timelapse filmed by NASA astronaut from onboard SpaceX Dragon shuttle | Watch | Hindustan Times – Hindustan Times
A NASA astronaut serving as the SpaceX Crew-12 commander captured a timelapse video of the Southern Lights, or Aurora Australis, from a SpaceX Dragon spacecraft. The footage shows “snake-like” auroras triggered by a solar flare, according to reports from Space.com and Inshorts, with NDTV describing the visual effect as “ethereal.”
How was the Southern Lights timelapse captured from the SpaceX Dragon?
The footage was recorded by the commander of the SpaceX Crew-12 mission using a timelapse photography technique from the observation windows of the SpaceX Dragon shuttle. According to reports from The Times of India and Hindustan Times, the astronaut filmed the shimmering lights as the spacecraft orbited the Earth, providing a high-altitude perspective of the atmospheric phenomenon.
The SpaceX Dragon is designed with specific viewing ports that allow crew members to observe the Earth and space. By using a timelapse setting, the astronaut was able to compress hours of geomagnetic activity into a short video, revealing the fluid, undulating motion of the lights that is often too slow for the human eye to perceive in real-time. Space.com noted that the resulting images displayed “snake-like” patterns, a characteristic often seen when high-energy particles interact with the Earth’s magnetic field at high velocities.
Key details of the capture include:
- Platform: SpaceX Dragon spacecraft.
- Personnel: SpaceX Crew-12 Commander (NASA astronaut).
- Visual Style: Timelapse video.
- Target: Aurora Australis (Southern Lights).
What caused the rare Southern aurora seen in the footage?
The appearance of these lights was the direct result of a solar flare, according to Inshorts. Solar flares are intense bursts of radiation coming from the release of magnetic energy associated with sunspots. When these flares are accompanied by Coronal Mass Ejections (CMEs), they send a stream of charged particles—mostly electrons and protons—hurling toward Earth at millions of miles per hour.
According to the scientific context provided by Space.com, these particles collide with the Earth’s magnetosphere. The magnetic field deflects most of these particles, but some are funneled toward the north and south poles. When these charged particles enter the upper atmosphere, they collide with oxygen and nitrogen atoms. These collisions excite the atoms, which then release energy in the form of light, creating the auroras.
The “rare” nature of the event mentioned by Inshorts refers to the intensity and visibility of the Aurora Australis. While the Northern Lights (Aurora Borealis) are more frequently documented due to the higher population density in the northern hemisphere, the Southern Lights are often more difficult to observe from the ground. Capturing them from a SpaceX Dragon provides a vantage point that bypasses terrestrial obstructions and atmospheric haze.
How do different news outlets describe the visual nature of the aurora?
Different media organizations have characterized the astronaut’s footage using varying descriptors, highlighting the subjective impact of the imagery. A comparison of the reporting shows a range from technical to emotive language.
| Source | Primary Descriptor | Focus of Report |
|---|---|---|
| NDTV | “Ethereal” | The atmospheric and ghostly quality of the lights. |
| Space.com | “Snake-like” | The physical shape and movement of the aurora. |
| Inshorts | “Rare” | The scarcity and timing following a solar flare. |
| Hindustan Times | “Stunning” | The overall visual impact of the timelapse. |
This contrast in framing shows that while the scientific community (via Space.com) focuses on the morphology of the lights, general news outlets emphasize the aesthetic and rarity of the event.
Why is space-based aurora footage different from ground observations?
Observation from a SpaceX Dragon shuttle offers a perspective that is physically impossible from the Earth’s surface. Ground-based observers see the aurora as “curtains” or “arcs” stretching across the sky, viewed from underneath. In contrast, the Crew-12 commander’s footage captures the aurora from above, looking down through the atmosphere.
According to the perspective provided by the timelapse, several factors differentiate this footage:
- Field of View: Astronauts can see the entire oval of the aurora surrounding the pole, whereas ground observers only see a small slice of the phenomenon.
- Atmospheric Interference: Space-based cameras operate above the thickest parts of the atmosphere, reducing the scattering of light and providing sharper contrast.
- Orbital Velocity: The SpaceX Dragon travels at approximately 17,500 miles per hour. This speed, combined with the timelapse technique, allows the astronaut to capture the evolution of the aurora across different geographic regions in a single sequence.

What are the implications of the solar flares that triggered this event?
While the resulting aurora is visually appealing, the solar flares that cause them can have significant technical implications for Earth. According to the context of solar activity reported by Inshorts and Space.com, high-energy solar events can interfere with various human technologies.

The same particles that create the “snake-like” lights can disrupt satellite communications and GPS signals. Because the SpaceX Dragon and the International Space Station (ISS) operate in the thermosphere and exosphere, they are more directly exposed to these solar particles than people on the ground. NASA and SpaceX monitor solar weather constantly to ensure the safety of the crew, as intense solar radiation can pose health risks to astronauts during periods of high solar activity.
The solar cycle, which lasts approximately 11 years, dictates the frequency of these flares. As the sun approaches “solar maximum,” the number of sunspots increases, leading to more frequent and intense flares. This makes the capture of such timelapses more likely as the cycle peaks.
Common misconceptions about the Southern Lights
The reporting on the “stunning” footage often leads to common misunderstandings about how auroras work. Based on the data from Space.com and the nature of the Crew-12 mission, the following clarifications are necessary:
Do auroras only happen at the poles?
While the most intense activity occurs in the “auroral ovals” around the North and South poles, strong solar flares can push the aurora toward the equator. However, the footage from the SpaceX Dragon specifically highlights the Southern Lights, which are concentrated around the Antarctic region.
Is the color always green?
Green is the most common color because it is produced by oxygen atoms at lower altitudes (around 60 to 150 miles). However, depending on the altitude and the type of gas involved, auroras can appear red, blue, or purple. The “ethereal” quality mentioned by NDTV often refers to these shifting color gradients captured in the timelapse.
Does the spacecraft’s speed affect the colors?
No. The colors are a result of chemical reactions in the atmosphere. The speed of the SpaceX Dragon affects the framing and the timing of the footage, but not the actual wavelength of the light emitted by the atoms.
Understanding the role of SpaceX in NASA missions
The fact that this footage was captured from a SpaceX Dragon highlights the shift in how NASA accesses space. The Crew-12 mission was part of the Commercial Crew Program, which utilizes private spacecraft to transport astronauts to and from the International Space Station.
The Dragon shuttle serves as both a transport vehicle and a temporary habitat. Its capacity for high-quality observation has turned it into a platform for both scientific data collection and public outreach. By sharing these timelapses, NASA and SpaceX provide the public with a visual connection to the physics of our solar system, transforming a scientific event (a solar flare) into a global visual experience.
