Where is everybody?

Most astrophysicists would agree that it’s highly likely that there’s life beyond Earth. But then why haven’t we found any? This month on Naked Astronomy, I tackle one of the fundamental questions of mankind with Neil deGrasse Tyson, Jim Al-Khalili and Dallas Campbell.

The End of Night?

As the northern hemisphere enters the dark depths of winter, days get shorter and nights get longer. Or at least that’s how it’s supposed to be. But since the invention of the light bulb, we’ve long been working towards the end of night. But does this matter? I investigate…

Connie won a meteorite

My colleague Connie won a meteorite and so I made it my mission to find out as much as possible about this hunk of space rock, including how I might go about finding one of my own…

Jupiter: King of the Planets

NASA’s Juno probe has reached Jupiter after a five year battle through our solar system and is orbiting the gas giant. But now it’s completed this death-defying stunt, what now? This month on Naked Astronomy, I colluded with the king of the planets to find out what it’s really all about…

Reaching for the Stars

This month, I get all starry eyed over our Sun. Where did it come from? Where is it going? And what it’s taught us about the universe? Plus, the mission that’s taking us the closer to the Sun than we’ve ever been before…

The Next Revolution in Astronomy: Gravitational Waves

This month, the LIGO team of astronomers announced they’d found gravitational waves, nearly 100 years after Albert Einstein had predicted them.  Everyone is getting very excited about the whole thing but I had a couple of questions of my own like if I dance around, do I create gravitational waves? And if so how big? And how much do they distort spacetime – could I momentarily get taller and skinnier (or shorter and fatter!)

I put these questions, as well as some more sensible ones, to the LIGO scientists to get to the bottom of how fundamental this detection is…

Cosmic Quandries: The Origins of Time

Last month, I launched my own podcast – Naked Astronomy and  thought what better place than to start a podcast all about cosmology than at the beginning of time!

One of the big questions in cosmology is what happened at the beginning of the universe and what happened before? Astrophysicists are edging closer to answering this question – we can now look back to a fraction of a second after the Big Bang. But what happened before that still remains elusive and there are still many loose ends to tie up. In this episode of Naked Astronomy, I take a look at the the origins of time…
