The center of the Milky Way is already crowded with stars. But in a few million years, tens of thousands more could flare to life in a region known as the Brick. It’s a vast cloud of cold, dark gas and dust that’s shaped like a brick.
One of the first items on almost any amateur astronomer’s “to-do” list is completing the Messier marathon — looking at all 110 objects cataloged by Charles Messier. Messier himself began the first marathon 250 years ago.

A bright star and a brighter planet are staging a beautiful encounter in the evening sky. They’re quite close together tonight, and will pass even closer over the next few nights.
Over the decades, when astronomers wanted a subject for testing new techniques for studying the stars, they frequently turned to Vega, the brightest star of Lyra, the harp.
