Geologists think they’ve found the oldest Earth rock ever seen. And they found it in one of the last places you’d ever suspect, on the Moon. When the Apollo 14 astronauts returned their lunar samples…

In this week's Questions Show, I wonder if there's a way ion engines can give us artificial gravity, if electromagnetic rail guns can launch space craft, and should we be worried about returning alie…

One of the big mysteries in astronomy is unfolding right before our eyes: fast radio bursts. And now a new Canadian radio telescope has come online, detecting many new bursts, including the second ev…

In this week's questions show, I wonder if we've already infected Mars with our Earth life, why we assume aliens build Dyson Spheres, and if you could link up 5 Hubble telescopes together.

The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to…

In this week's questions show, I wonder if moons could be geostationary, if we could detect Hawking radiation, if SETI is pointless, and why I'm always talking to people like they're 11. as the Sun. …

Thanks to the hardworking Gaia spacecraft, astronomers think they’ve located a star that formed from the same solar nebula as the Sun. In fact, this star is a virtual twin of the Sun and it’s actuall…

In this week's questions show, I wonder how well we'll be able to survive various extinction scenarios, can mobile apps help you learn the night sky? What would we do if Tunguska happened today? And …

It’s been about a year since the mysterious interstellar asteroid (or maybe comet) Oumuamua passed through our Solar System. It was going so fast and was so far away that astronomers could see very l…

In this week's questions show, I wonder if we'll have enough time to respond to an asteroid or comet, if we're going to fill the asteroid belt with space junk and if antimatter engines are the best w…

In the pristine icy environment of Antarctica, there’s a telescope, embedded into an ancient glacier. The telescope is observing the Universe, directly through the Earth, using a cubic kilometer of i…
