Universe Today podcasts with Fraser Cain

In this QA from Iceland, astrophysicist Dr. Paul Sutter steps in to tackle some of the more complicated cosmology and physics based questions from the audience. Did the Big Bang create the matter of the Universe, how close are we do discovering what dark matter is, and more.

There are few rockets more iconic than the RS-25, also known as the Space Shuttle main engine. Even though it’s been around in some form since the 1970s, it’s been improved and upgraded several times, making it the most efficient liquid fuel rocket engine going today. And now the RS-25 is going to see a new chapter in its history, working to carry NASA’s new Space Launch System back to deep space, beyond Earth orbit.

In this week's questions show, I talk about being wrong, why I'm such a buzz kill to sci-fi, and what I'd launch on a Falcon Heavy.

You might have heard of the recently solved Pioneer anomaly. But what about the flyby anomaly? The unexpected velocity change that happens during gravitational slingshots.

In this week's questions show, Fraser is excited to see the southern hemisphere night sky, considers how the next generation of telescopes will change our understanding of the Big Bang, and suggests what you should look at with a new telescope.

When astronomers scan the atmospheres of other worlds, they’ll be looking for gases to confirm that yes, indeed, there’s life there. It turns out, this is actually pretty tough.

In this week's questions show, Fraser wonders where you'd have to go in the Universe to minimize your time dilation, how to see Iridium Flares, how interferometry works, and more.

When we see images of space, it’s hard to know which are real images and which are artist illustrations.
