NASA astronauts capture images of Southern Lights from space station

NASA astronauts aboard the International Space Station (ISS) have shared spectacular images of the Southern Lights, also known as the aurora australis. The celestial display was visible over the southern hemisphere during the past weekend, offering a breathtaking view from orbit.

Astronaut Jessica Meir, part of the SpaceX Crew-12 mission, posted on social media platform X, describing the event. "There is a lot of activity right now on the Space Station, but fortunately we are all safe and yesterday we witnessed a spectacular display of southern lights thanks to a recent solar event," she wrote. Meir accompanied her post with several photographs and a video clearly showing the aurora's vibrant green hues illuminating Earth's atmosphere in a river-like flow.

The phenomenon of auroras, both austral and boreal, occurs when solar particles collide with Earth's magnetic field. While these events do not pose a significant danger to the ISS crew, they do result in slightly higher radiation exposure than usual. The primary distinction between the two is their geographical location: auroras australes appear in the southern sky, while auroras boreales are visible from northern latitudes.

Observing the aurora australis from the ground can be challenging due to the limited population centers in the southern hemisphere, which is largely comprised of Antarctica and oceans. The optimal viewing period for the Southern Lights is between March and September, coinciding with the winter months in the southern hemisphere.
