Ep. 468: Simulations for Science and Fun

365 Days of Astronomy - Weekly Edition ·

2017/12/04

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.

Ep. 467: Resonance

365 Days of Astronomy - Weekly Edition ·

2017/11/27

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?

Ep. 466: Origins of Zero (0)

365 Days of Astronomy - Weekly Edition ·

2017/11/20

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?

Ep. 465: Exploiting Interfering Light

365 Days of Astronomy - Weekly Edition ·

2017/11/10

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.

Ep. 463: Pareidolia and the Moon

365 Days of Astronomy - Weekly Edition ·

2017/10/30

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 behavior, and how can we use this to debunk some hilarious conspiracy theories?

Ep. 462: Modeling the Weather

365 Days of Astronomy - Weekly Edition ·

2017/10/24

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.

Ep. 461: Measuring the Weather with Satellites

365 Days of Astronomy - Weekly Edition ·

2017/10/16

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.

Ep. 460: Earth from Afar: Remote Sensing

365 Days of Astronomy - Weekly Edition ·

2017/10/09

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.

Ep. 459: Arecibo Observatory

365 Days of Astronomy - Weekly Edition ·

2017/10/02

The iconic Arecibo Radio Observatory has been a mainstay in science and science fiction. This Puerto Rico-based radio telescope was already in an uncertain level of funding. But now with the damage from Hurricane Maria, it might be shut down forever.

Ep. 458: The Science of Cassini

365 Days of Astronomy - Weekly Edition ·

2017/09/25

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.

Ep. 457: Why Did Cassini Have To Die? In Memoriam

365 Days of Astronomy - Weekly Edition ·

2017/09/18

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.

Astronomy Cast Ep. 450: Inflatable Habitats

365 Days of Astronomy - Weekly Edition ·

2017/05/23

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.

365 Days of Astronomy - Weekly Edition ·

2017/05/08

When you think of a robot, you're probably imagining some kind of human-shaped machine. And until now, the robotic spacecraft we've sent out into space to help us explore the Solar System look nothing like that. But that vision of robots is coming back, thanks to a few new robots in development by NASA and other groups.
