Astronomers depend on simulations to study the Universe. From relatively straightforward orbital simulations to vast simulations that try to recreate the large scale structure of the Universe from the Big Bang. Today we're going to talk about some of those simulations, as well as tools you can use simulate the Universe.

466: Origins of Zero (0) Astronomy Cast 466: Origins of Zero (0) by Fraser Cain & Dr. Pamela Gay

Many of the moons and planets across the Universe are in resonance with each other and their star. What causes this resonance, and how can it help us understand the history of planetary formation and migration?

We depend on zero for our math to work right, but this number was actually invented in fairly recent times. Why do we need zero? Was it inevitable?

465: Exploiting Interfering Light Astronomy Cast 465: Exploiting Interfering Light by Fraser Cain & Dr. Pamela Gay

Electromagnetic radiation, also known as “light” is pretty handy for astronomers. They can use it to directly and indirectly observe stars, nebula, planets and more. But as you probably know, light can act like a wave, creating interference patterns to teach us even more about the Universe.

464: Why the Hype over an Exorock? Astronomy Cast 464: Why the Hype over an Exorock? by Fraser Cain & Dr. Pamela Gay

Astronomers this week announced that they had discovered an asteroid or comet on a trajectory that brought it from outside the Solar System? Is this the first case of an object from deep space? And what can we learn from this discovery?
