This week on Looking Up we learn about a distant star that sure could use a leg up on finding another supply of hydrogen for its core.

If you have been thinking that these Looking Up segments are increasingly going to the dogs, I must agree, at least about today, because I want to tell you about a neat star in the constellation Canis Major, or the big dog, that follows Orion the Hunter across the Colorado night sky right now. The special star is Mirzam, the right front leg of the big dog, below and to the right of the brightest star in the sky, Sirius.
