Astronauts Capture Stunning Image of Comet Lemmon Amid Auroras
Recent solar activity has captivated skywatchers, scientists, and astronauts aboard the International Space Station (ISS). On November 20, 2025, the sun unleashed its most significant eruptions of the year, resulting in spectacular auroras that extended into areas as far south as Mexico. During this celestial event, astronauts on the ISS managed to photograph comet Lemmon against the backdrop of these vibrant auroras.
Understanding Comet Lemmon
Comet Lemmon, officially known as C/2012 F6 (Lemmon), was discovered in 2012 by the Mount Lemmon Survey in Arizona. This long-period comet, which originates from the distant Oort Cloud, takes approximately 1,350 years to complete its orbit around the sun. As it approaches the sun, the comet warms, releasing gas and dust that create its characteristic glowing tail.
The image captured from the ISS showcases the comet’s white tail as it appears to glide near the stunning auroras visible from Earth. The ISS orbits the planet at an average altitude of about 250 miles (400 kilometers), providing a unique vantage point for such astronomical phenomena.
The Significance of the Event
Comets are relatively rare in the night sky due to their long orbits, making this sighting particularly noteworthy. The juxtaposition of comet Lemmon against the backdrop of the brilliant auroras is a rare occurrence, and this photograph serves as a reminder of the dynamic and interconnected nature of our universe.
The interaction between solar activity and cometary bodies emphasizes the complexities of our solar system. As the sun continues to influence space weather, events like this highlight the beauty and wonder of astronomical phenomena.
