The Physics Teacher
Volume 59 Issue 3
This month's cover is a blue-light image of one of the oldest stars in our galaxy, taken by the Anglo-Australian Observatory (AAO) UK Schmidt telescope. (Note that the “plus sign” centered on the star is not part of the star itself but rather a diffraction effect due to the mirror supports.) This star is also known as the Methuselah star, and its precise age is a matter of special interest since upon casual inspection, one might conclude that it is older than the rest of the universe. Don Lincoln vividly relays this apparent paradox in his article “Have Astronomers Found a Star Older Than the Universe?” Enjoy!
