A meteoroid streaking through the sky is always a spectacular sight, and it's rare to capture one on video. Yet, according to a story on Norway's NRK.no, skydiver Anders Helstrup managed to do the next-to-impossible: he caught one on video in broad daylight, after it had burned out.
When a meteoroid enters Earth's atmosphere, it's travelling so fast that it compresses the air in front of it, heating the air until it glows in the bright streak of light that we call a meteor. The friction with the atmosphere causes the meteoroid to slow down, so that it eventually enters its 'dark flight' — the point where it's still falling through the sky, but it's not moving fast enough to produce the meteor trail. Essentially, it just becomes a rock that's free-falling towards the ground, going about 300 kilometres per hour, tops. Also, the rock itself is so cold to its core from being in the depths of space that, although the outer layers can heat up as the air around it heats up, as soon as itRead More »from Skydiver records incredibly rare event as falling meteoroid nearly hits him
