Attention star gazers!

Alert Museum staffer Angi Burgess let us know about this cool thing coming up tomorrow night, Thursday, Aug 27!


SEE ANTARES
At nightfall on August 27, the first-quarter Moon is very near a brilliant bright star at nightfall. This star is the famous red star Antares A. Antares is the brightest star in the constellation of Scorpius—a red glow at the scorpion’s heart.

Antares is commonly mistaken for Mars because of its reddish hue, a fact shown by its name “Ant-Ares,” which means “like Mars,” with “Ares” being the Greek name for the god of war.

Antares is a true red supergiant, which means that it has consumed all of its hydrogen. This huge star is about 700 times the diameter of our own Sun and 10,000 times brighter.

Here is how the earth compares to the sun....




and how our sun compares to Antares. WOW!

Visit SPACE ADVENTURES, the exhibit, before it closes THIS SUNDAY August 30!
