March 24 2019 Astronomy Newsletter

Hi everybody

Here are the two latest articles from the Astronomy site at

Boötes - the Herdsman
This ancient constellation contains black holes as massive as a billion Suns, extrasolar planets and has acquired a meteor shower from an extinct neighbor. Its brightest star, a red giant 25 times the diameter of the Sun, is a sign that spring is here.

Luna - Earth's Daughter
The Moon has always been our celestial companion, lighting the night, its changes serving as a calendar. What is it, where did it come from, why do we only see one side of it, what is our future together?

Boötes has been updated, new information added and links repaired and improved. The Moon article is a new one to replace a sketchier one from many years ago.
