One of the most exciting things about meteor showers is their sheer unpredictability. Just when astronomers think they
know all about a particular shower, something happens to spring a surprise. One of the least predictable of the annual
meteor showers is the Leonids, which appears each year around 16-18 November.

Although this year’s shower is not expected to reach storm proportions, ESA scientists are continuing their efforts to
learn more about the cosmic debris that is incinerated as it enters Earth’s upper atmosphere.
