Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's February 12, and today's image is a real treat from the surface of Mars.

In it we see the larger of Mars' two moons, Phobos, passing in front of the Sun.
