What’s That Blazing Across the Sky?

A brilliant flash of light pierces the sky, capturing the attention of onlookers and flooding social media with videos and hashtags. But what exactly have people witnessed? Was it an ancient Russian probe, a satellite from Elon Musk, or perhaps a meteor? Let’s unravel the mysteries behind these fiery scenes!

Understanding Fireballs: Shooting Stars, Meteors, and Comets

Shooting stars are often spotted on clear, dark nights, streaking across the sky in split-second brilliance. Despite their name, these meteors are not stars at all. They occur when tiny dust and pebble particles collide with our atmosphere, igniting as they burn up at altitudes over 50 kilometers. Interestingly, comets are a major source of this space debris, and Earth experiences meteor showers as it crosses through their trails.

These fleeting lights can display a dazzling array of colors, depending on their chemical makeup—think iron, magnesium, and calcium. While the terms ‘meteors’ and ‘shooting stars’ are often interchangeable, ‘bolides’ refer to larger, more spectacular meteors that can outshine the brightest stars and lead to sonic booms as they crash through the atmosphere.

Space Junk: The Modern Menace

Lately, skywatchers might wonder if what they sighted was space junk. With the surge in rocket launches and satellite deployments, the odds of witnessing a piece of human-made debris re-entering the atmosphere have significantly rose. Just like meteors, this junk burns brightly and can reveal hues corresponding to materials like steel and aluminum as it descends.

However, there are distinct characteristics that set space junk apart from meteors. Unlike meteors that zip through the atmosphere at staggering speeds, space junk usually enters more horizontally and at a slower pace of about 8 kilometers per second, taking several minutes to burn up. This slower trajectory often allows witnesses time to grab their phones for a memorable photo op.
