"Galileo's Pendulum" is a blog covering physics, astronomy, math, and related topics - all for a non-specialist audience. I am especially interested in showing how science actually works, and how the various conceptual pieces fit together to make the theoretical framework that provides the best description of the natural world.

Gravitational lenses provide some of the most incredible images in astronomy. As the gravity from massive objects — generally galaxies or galaxy clusters — bends the path of light from more distant sources, it produces multiple distorted images, rings, crosses, and other wonderful things. Even stars can serve as lenses, but they are too small […]
Last week’s big astronomy news was the discovery of a planet nearly the same size as Earth. This new discovery, known as Kepler-186f, is well within its host star’s habitable region, so it could conceivably have liquid water on its surface. Since all life as we know it requires liquid water in some form, that’s […]

Roughly 5 billion years from now, our host star will exhaust the hydrogen fuel in its core and expand into […]
