Last month in this column, I began an exploration of Canis Major
, the Big Dog.
The star Mirzam or beta ([beta]) Canis Major
, was often combined by the Arabs with the star beta ([beta]) Canis Minor (Gomeisa) and these two beta stars together were called The Announcers, heralding the coming of Sirius, the biggest star in the sky.
30 with an instrument capable of seeing ultraviolet light - Dual-channel Extreme Ultraviolet Continuum Experiment, or DEUCE - that will "measure starlight from a pair of nearby hot stars in the constellation Canis Major
, aiming to help researchers understand how the IGM got to its current state," the space agency said in a statement Saturday.
Remaining visible through the next few months, this star cluster will eventually be joined in the sky by Taurus, Orion, Gemini and Canis Major

You can catch Canis Major
, the great dog, Orion the hunter easily identified by Orion's belt (three bright stars in a straight line), the twins of Gemini, Perseus the hero and many deep sky objects such as globular clusters, bright nebulae and galaxies.
Andromeda is having a tough time since Canis Major
ran off with Lyra - cut her some slack.

Since ancient times Sirius has been "the Dog Star," the outstanding light of Canis Major
, the Big Dog.
The Triangle is composed of Betelgeuse, the supergiant red star and the prominent star of the famous constellation Orion (the Mighty Hunter); Sirius, the brightest star in the constellation Canis Major
(the Big Dog), and Procyon, the brightest star in the constellation Canis Minor (the Little Dog).
For example, they spotted an area near Canis Major
with 30 or more young stars sprouting jets of material, an early phase in their lives.
