Ep. 150: Telescopes, the Next Level

We’ve explained how to get into astronomy and buy your first telescope. Now we’re going to take things to the next level and get you drooling about bigger and better telescopes. If you’re serious about astronomy, what kinds of telescopes will give you the best bang for big bucks?

Ep. 149: Constellation Program

It’s been more than 40 years since humans first set foot on the Moon. But plans are in place to return humans to the surface of the Moon, and maybe even to asteroids and the planet Mars. New rockets, landers and flight technology are all under development. Humans are pushing out into space again, and this time we’re going to stay. Let’s take a look at NASA’s new Constellation Program. What’s been developed so far, and what’s coming up.

Ep. 148: Astronomy and New Media

Astronomy is one of the scientific fields that have been completely shaken up by new media. The Internet has enabled communication between researchers in a dramatic new way, creating new collaborations, removing obstacles, and drawing in an army of enthusiastic volunteers to help with research. Let’s take a look at how new media is helping change astronomy, and how you can get involved.

Ep. 147: How to Be Taken Seriously By Scientists

For those non-scientists trying to get their original ideas accepted by the scientific community, you’ve got to have thick skin. It might seem like there’s a vast conspiracy, or a general attitude that drives away original, but unorthodox ideas. But that’s not true, the reality is that great ideas in science come from everywhere, even amateurs. In this episode we’ll help you understand what scientists will be looking for, and the best ways to be taken seriously.

Ep. 146: Astronomy Research from Idea to Publication

Have you ever wondered how astronomers do their research? How do they go from idea or question, to gathering their data, to publishing the research. What are all the hoops they have to jump through, the paperwork to fill out, and the cool toys they get to use along the way?

Ep. 145: Interstellar Travel

In science fiction it’s easy to hop into your spaceship and blast off for other stars. But the true distances between stars, and the limits of relativity make interstellar travel almost impossible with our current technology. What would it really take to travel from star to star, exploring the galaxy?

Ep. 144: Space Elevators

If you want to travel into the Solar System, you have to get off the Earth. Traditionally, that meant blasting off in a rocket. But there’s another strategy for escaping the Earth’s gravity. Climb to the top of an extremely tall tower, and just jump away. That’s the idea behind space elevators. Theoretically possible, but practically unfeasible, space elevators have gotten new life thanks to new, super strong materials.

Questions Show: Matter Balance, Jumping Light Speed and Black Hole Star Formation

Why was there a difference between the amount of matter and antimatter at the beginning of the Universe? Mathematics lets us travel faster than light speed, so why can’t we? And are there stars forming around black holes?

Ep. 143: Astrobiology

We know there’s life in the Universe. We see it all around us here on Earth. But is there life anywhere else? By studying the extremes that life can take here on Earth, scientists are learning just how hardy and adaptable life can really be. And if you consider other ways that life might function, the options open up considerably. This week we’ll discuss the study of life – extreme life here on Earth, and the possibility of finding life on other worlds.
