Sun, 28 Aug 2016 - A new arrival at the Zoo

You may be already familiar with the Zooniverse via projects such as Galaxy Zoo or via Alice Sheppard's regular Citizen Science articles in  Popular Astronomy magazine.

The Zooniverse is based around the recognition that ordinary members of the public with no scientific background can often outperform automated software when it comes to classifying objects (such as different types of galaxy).

The latest addition is the Radio Meteor Zoo, organised by the Belgian BRAMS team, who regularly monitor for the reflection (echo) of radio signals by the ionisation trails of meteors in the upper atmosphere.

To take part you don't need to know anything about "underdense echoes" or "overdense echoes" or the strange "epsilon echoes".

You also don't need to know anything about radio signals ... or even anything about meteors.

All you need to be able to do is to look at a series of images and draw rectangles around those that contain shapes that look like meteor radio echoes.

... and to get you started, there is a helpful tutorial that tells you what a meteor radio echo looks like.

If you would like to know more about meteor radio astronomy, there is also this helpful overview , which explains how radio forward scatter works and also includes this informative diagram
