Podcast: Gravitational Waves

lisamain_image.thumbnail.gif

When he put together his theories of relativity, Einstein made a series of predictions. Some were confirmed just a few years later, but scientists are still working to confirm others. And one of the most fascinating is the concept of gravitational waves. As massive objects move in space, they send out ripples across the Universe that actually distort the shape of matter. Experiments are in place and in the works to detect these gravitational waves as they sweep past the Earth.

Just a couple of shows ago, we showed you how to get a career in astronomy. Now that you’ve got your career in astronomy, obviously the next goal is to win a Nobel prize. We’re here at the American Astronomical Society meeting in Austin, which is just one tiny step that a person has to take before you get that Nobel prize. Before you get that call in the middle of the night from Sweden, you’re going to need to come with an idea, do some experiments, write a paper, get published and a bunch of other stuff. This week, we’ll tell you all about it.

Podcast: The Large Hadron Collider and the Search for the Higgs-Boson

When it was first developed, the standard model predicted a collection of particles, and thanks to more and more powerful colliders, physicsists have been able to find them all except one: the Higgs-Boson. It’s an important one because it should explain how objects have mass. The European Large Hadron Collider should have the power and sensitivity to find the Higgs-Boson.

Podcast: Globular Clusters

This week we’re going to study some of the most ancient objects in the entire Universe; globular clusters. These relics of the early Universe contain hundreds of thousands of stars, held together by their mutual gravity. Since they formed together, they give astronomers a unique way to test various theories of stellar evolution.

Podcast: Building a Career in Astronomy

2007-1217hubble.thumbnail.jpg

With all the enthusiasm that’s being generated with astronomy, it’s had a bit of a strange side-effect. We’ve been causing some of our listeners to have midlife crises about their careers. We’ve had other people who just want advice – they’re moving into college for the first time and they want to direct the courses they’re going to be taking into astronomy. Some other people already have skills that are very useful and have wondered how they can help up or even change their career to be working in the field. We thought we’d try and answer everyone’s questions all at once and just run through the major career paths you can take that relate to astronomy and space, and the kinds of things you’ll need to do to actually make yourself a good candidate for that field.

Podcast: How Amateurs Can Contribute to Astronomy

Astronomy is one of the few sciences where amateurs make meaningful contributions to discoveries. Many professional researchers work hand-in-hand with teams of amateurs to make discoveries that just wouldn’t be possible without this kind of collaboration. In fact, Pamela regularly relies on dedicated enthusiasts for her data on variable stars.

Podcast: The End of Our Tour Through the Solar System

2007-1203heliosphere.thumbnail.gif

All good things come to an end – we now find ourselves in the outer reaches of the solar system where our Sun is hard to distinguish from the other bright stars in the sky. But we’re not done with the solar system, there’s some stuff that’s leftover. This week, we look at the outer reaches of the solar system and how it interacts with the rest of the universe.

Podcast: Pluto and the Icy Outer Solar System

It’s been a long journey, 64 episodes, but now we’re back where we began: Pluto. Last time we talked about how Pluto lost its planethood status, so we won’t go over all that again. This time we’re going to talk about Pluto, its moons, the Kuiper belt, and the other icy objects that inhabit the outer Solar System.

We’ve reached Neptune, the final planet in our tour through the solar system – but don’t worry! The tour’s not over, but after this week we’ll be all out of planets. Neptune has a controversial story about its discovery, some of the strongest winds in the solar system and some weird moons.

Podcast: Uranus

This week, we’re on to the next planet in the solar system. Having only visited it up close once with Voyager 1, we don’t know much about this sideways-spinning ice giant. But today we’ll cover what we do know, including its faint rings, sideways axis of rotation and rocky core – a first in the gas planets we’ve encountered so far in our tour.
