Episodes

Ep. 469: Best Modern Sci Fi for the Science Lover - Part 1 Space Exploration

12/8/2017
More
We’ve always been fans of science fiction, but we really like our science. Today we’ll talk about some books we’ve been reading recently that do a good job of dealing with the science in science fiction.

Duration: 00:31:20


Ep. 468: Simulations for Science and Fun

12/1/2017
More
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.

Duration: 00:30:13


Ep. 467: Resonance

11/19/2017
More
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?

Duration: 00:30:27


Ep. 466: Origins of Zero (0)

11/17/2017
More
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?

Duration: 00:28:34


Ep. 465: Exploiting Interfering Light

11/10/2017
More
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 tto teach us even more about the Universe.

Duration: 00:28:46


Ep. 464: Why the Hype over an Exorock?

11/6/2017
More
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?

Duration: 00:27:51


Ep. 463: Pareidolia and the Moon

10/30/2017
More
The man in the moon, the pyramids on Mars. Every cloud, ever. Humans have a tendency to pattern match when they're looking around the Universe - it's called pareidolia. What causes this behaviour, and how can we use this to debunk some hilarious conspiracy theories?

Duration: 00:24:41


Ep. 462: Modeling the Weather

10/23/2017
More
Have you noticed that weather forecasting has gotten much better in the last few years? Thanks to weather satellites, weather stations, and better forecasting techniques. How do scientists predict the weather with any kind of accuracy days or even weeks in the future.

Duration: 00:28:41


Ep. 461: Measuring the Weather with Satellites

10/16/2017
More
What’s the weather doing? Is it going to rain today? How much? What about temperatures? We depend on modern weather forecasting, thanks, in part to the vast network of weather satellites. What instruments do they have, what orbits do they use.

Duration: 00:29:42


Ep. 460: Earth from Afar: Remote Sensing

10/9/2017
More
The space age has given us the ability to look at every corner of the globe in every wavelength. It’s revolutionized our ability to predict the weather, keep track of environmental damage, and watch the world change. Today we look at what missions and technologies give us the ability to watch our world from afar.

Duration: 00:30:48


Ep. 459: Arecibo Observatory

10/2/2017
More
And now Cassini’s gone. Smashed up in the atmosphere of Saturn. But planetary scientists are going to be picking through all those pictures and data for decades. Let’s look back at some of the science gathered up by Cassini so far, and we can still learn from this epic journey.

9/18/2017
More
It's time to say goodbye to an old friend, NASA's Cassini spacecraft, which has been orbiting within the Saturnian system since 2004. But why does a seemingly healthy spacecraft and mission need to come to an end? Today we look back at the mission, some of the amazing discoveries, and why its finale was necessary.

Ep. 450: Inflatable Habitats

5/21/2017
More
In order to live in space, we'll need to live in a habitat that simulates the temperature, pressure and atmosphere of Earth. And one of the most interesting ideas for how to do this will be with inflatable habitats. In fact, there are a few habitats in the works right now, including one attached to the International Space Station.
