When is a double fireball not a double fireball? Astronomers explain the viral meteor videos and the trick of the light behind them

Recently, videos depicting two bright fireballs in the evening sky have gained significant traction on social media, leading many viewers to believe they were witnessing a rare double meteor display. However, experts have clarified that the phenomenon is an optical illusion. The observations were not due to two separate meteors, but rather the reflection of a single meteor caused by light interacting with surfaces such as clouds or camera lenses.

Meteors occur when fragments of rock or space debris enter the Earth’s atmosphere at high speeds, creating a bright flash of light as they burn up. The analyzed videos revealed that the two streaks moved in perfect sync regarding speed and direction, indicating they were reflections rather than distinct objects. Sometimes, observers may have viewed the meteor through glass, contributing to this misperception.

This situation illustrates how easily our perceptions can be deceived by light and reflections, similar to phenomena seen during sunsets or when viewing bright stars.

Why it matters:

• Understanding optical illusions enhances public awareness of astronomical phenomena, potentially leading to greater interest in astronomy.
• Clarifying such events may encourage the public to engage in legitimate skywatching opportunities, such as upcoming meteor showers.

The latest:

• Astronomers are promoting skywatching for the Orionid meteor shower and the imminent Leonids, which promise genuine meteor sightings.
