Today on StarDate

August 3-9: Magnetars

It may sound like a villain from a Marvel comic book, but a magnetar is really the “corpse” of a once-mighty star — and the most powerful magnet in the universe. Join us for magnetars and much more.

August 10-16: Galactic Hub

The center of our Milky Way galaxy is filled with massive stars, massive gas clouds, and a supermassive black hole. Join us for details on the galactic center, plus a look at the Perseid meteors and more.

August 17-23: Moon meanderings

The Moon moves by a couple of colorful objects this week — the golden planet Saturn and the orange star Antares, and we’ll have details. We’ll also talk about some astronomical discoveries made in an unusual lab.

August 24-30: Hunting Planets

Astronomers at McDonald Observatory are hunting for a special class of planets, known as cold Jupiters. They can tell us a lot about whether our own solar system is different from the rest or just one of the pack.
