ESA astronaut Sophie Adenot shared a timelapse video of a vivid green aurora captured from low-Earth orbit during the εpsilon mission [1].

The footage provides a rare perspective of Earth's atmospheric phenomena, highlighting the visual scale of geomagnetic activity as seen from the International Space Station.

Adenot captured the imagery on day 139 [1] of the mission. The recording took place during orbit 2,155 [1]. She said the sight was the most spectacular of the εpsilon mission to date [1].

In a separate report, the display was called "absolutely spectacular" [2]. The astronaut paired the timelapse with specific music to enhance the experience for the public [1].

This release is part of the ongoing effort by the European Space Agency to share the visual beauty of space and the unique vantage point of the ISS [1]. The green hue of the aurora is a result of charged particles colliding with oxygen in the Earth's atmosphere, a process that creates a shimmering light show visible from the station's observation ports.

By documenting these events, astronauts provide both a public service in science communication and a record of atmospheric conditions from orbit [1]. The εpsilon mission continues to document the planet from above, utilizing the station's position to monitor various natural occurrences.

“the most spectacular of the εpsilon mission to date”

The sharing of high-quality orbital imagery by ESA astronauts serves to bridge the gap between complex atmospheric science and public engagement. By documenting specific orbits and mission days, the agency creates a chronological visual record of solar activity and its interaction with Earth's magnetic field.
