(Updated May 24)
A brand new meteor shower occurred in the early morning hours Friday May 23 to Saturday May 24 called the Camelopardalids.
A meteor shower happens when particles from space -- meteors -- pass into the Earth's atmosphere at the same time, or when the Earth passes through a debris trail left behind by a comet. Some people call them "shooting stars." There are several meteor showers every year, like the Perseids pictured here. This meteor shower is predicted to occur again in August.
Orionids. These small chunks of ice, rock, and minerals were left behind by Haley's Comet. We'll see them again on October 21 this year, according to predictions.
Other meteor showers occur regularly, and some can be predicted at certain times of the year. For example, the Lyrids are formed by debris from Comet Thatcher and can be seen in late April. The intensity or brightness and length of meteor showers vary. Websites like Spacedex offer a list of meteor shower predictions to help flag these dates.
Scientists had predicted the new Camelopardalids meteor shower on May 23-24 would be as strong as the Perseids. The radiant or the point from which it radiates is large, so scientists anticipated it would be a strong and bright meteor shower. It's caused by debris from comet 209P/LINEAR located between the constellations of Ursa Major and Cassiopeia, and it's named after the constellation Camelopardalis (the giraffe). Because it had never been seen before, it was difficult to predict exactly when it would appear or how bright it would be, but NASA set up a live feed to view the shower.
As it turned out, the meteor shower disappointed most viewers. One reported seeing about 10 meteors throughout the night. Here is a round-up of links (and I will add more over the weekend):

Twitter followers reported being disappointed, but as one said, it was better to be informed of the event in advance: https://twitter.com/hashtag/camelopardalids?src=hash
