Astronomy Cast Ep. 516: Polar Vortices
It’s cold right now. Okay, fine, here on Vancouver Island, it’s actually pretty warm. But for the rest of Canada and big parts of the US, it’s terrifyingly cold. Colder than Mars or the North Pole cold. This is all thanks to the break up of the polar vortex. What are polar vertices, how do they form, and where else to we find them in the Solar System?

Astronomy Cast Ep. 515: Space Radiation
Space is a hostile environment in so many ways. But one of its worst features is the various kinds of radiation you can find. When astronauts go back beyond the protective environment of the Earth’s magnetosphere, what are the various kinds of radiation they’ll encounter. And is there anything we’ll be able to do about it?
Weekly Space Hangout: Jan 23, 2019: Marco Parigi, Asteroid/Comet Whisperer
Hosts:
Fraser Cain (universetoday.com / @fcain)
Dr. Morgan Rehnberg (MorganRehnberg.com / @MorganRehnberg & ChartYourWorld.org)
Marco is a self-declared Asteroid/Comet whisperer. He’s dabbled in citizen science for years, and he most recently flagged many changes on 67P when this was directly requested through the Rosetta Blog:
http://blogs.esa.int/rosetta/2016/06/03/the-changing-comet-call-for-contributions/ He is currently working on finding evidence for out gassing and stretch at Ultima Thule (similar to 67P), predicting an outburst for RYUGU when an impactor is fired into it in March, and helping with the engineering and physics of a propellant-less thruster based on capacitors called the IMFAB. Marco can be found on twitter at @marcoparigi1.

Astronomy Cast Ep. 514: Planetary Protection Protocols
As we send rovers and landers to other worlds, we have to think about the tiny microbial astronauts we’re sending along with us. In fact, NASA is so concerned about infecting other worlds that it has established the planetary protection protocols. Just to be safe.

Weekly Space Hangout: Jan 16, 2019: Paul MacNeal of JPL’s Annual Invention Challenge
Hosts:
Fraser Cain (universetoday.com / @fcain)
Dr. Pamela Gay (astronomycast.com / cosmoquest.org / @starstryder)
Dr. Morgan Rehnberg (MorganRehnberg.com / @MorganRehnberg & ChartYourWorld.org)
This week’s guest Paul MacNeal, a mechanical systems engineer at JPL, created the Annual Invention Challenge twenty-one years ago after helping his son with an extra credit assignment. Since then, teams of high school students from around the world compete each year against JPL engineers to see who can design and build the smartest and most efficient machine. The objective of the 2018 Challenge, which took place on Friday, December 14th, was to “to get a 24-inch length of two-inch PVC pipe from a horizontal position to an upright position on a platform using whatever device they could come up with, instructions not included.”
Astronomy Cast Ep. 513: Stellar Fusion
The Sun. It’s a big ball of fire, right? Apparently not. In fact, what’s going on inside of the Sun took us some time and knowledge of physics to finally figure out: stellar fusion. Let’s talk about the different kinds of fusion, and how we’re trying to adapt it to generate power here on Earth.
We usually record Astronomy Cast every Friday at 3:00 pm EST / 12:00 pm PST / 20:00 PM UTC. You can watch us live on AstronomyCast.com, or the AstronomyCast YouTube page.
