Space Probes
I detail the odysseys of three of my favorite probes: Curiosity, Cassini-Huygens, and Voyager 2. This blog is packed with breathtaking pictures.

Time Travel
I explore the possibility of time travel. Surprisingly, this common motif of science-fiction may not be out of the question in reality. The trick, it seems, is to simply go really, really, REALLY fast. For more information, read on.

Astronomical Distance
I describe one of the easier-to-understand methods used by astronomers to determine the distance to nearby stars.

Cosmic Microwave Background
I tell the story of one of the 20th century’s greatest scientific discoveries, and detail what this discovery means for us and our Universe.

Interstellar Travel
I explain the feasibility issues of traveling interstellar distances, and describe one idea that may, far in the future, circumvent some of these problems.
