First green source in Tucana
The first green source in Tucana is unknown.

The field of green astronomy is the result of observations and theories about green, or green-ray sources detected in the sky above.

The first astronomical green source discovered may have been the Sun.

But, green rays from the Sun are intermingled with other colors so that the Sun may appear yellow-white rather than green.

The early use of sounding rockets and balloons to carry green, optical, or visual detectors high enough may have detected green-rays from the Sun as early as the 1940s.

This is a lesson in map reading, coordinate matching, and searching. It is also a project in the history of green astronomy looking for the first astronomical green source discovered in the constellation of Tucana.

Nearly all the background you need to participate and learn by doing you've probably already been introduced to at a secondary level and perhaps even a primary education level.

Some of the material and information is at the college or university level, and as you progress in finding green sources, you'll run into concepts and experimental tests that are an actual search.
