light pollution

Smokey Skies and Gallant Grandmothers

This week, we’re excited to air an interview done by fellow CJSR star Nigel Henri Robinson, host of the CJSR show Acimowin, who spoke with the English Bay Grandmothers about their work fighting against oil extraction and development on the Cold Lake First Nations.

While we were preparing for this show we were surrounded by wildfire smoke in Edmonton that has turned the city disturbingly apocalyptic.  We were inspired to air an archive story from 2012 about light pollution and sustainable lighting to cap off the episode.

Down to Earth with Some Out of this World Folks

Cygnus Loop Supernova Blast Wave

In this week’s episode some average-joe Terra Informers take a walk with the stars. Find out what is so exciting about the observatory even when you can’t see the stars, learn whats up with light pollution, and hear a down-to-earth interview with a man who has been to space and back.

What’s space to you?

Many people come out to the University of Alberta observatory despite poor visibility. We wanted to find out: what would they think if they could no longer see the stars? And why would they spend a Thursday evening listening to a guy talk about hydrogen?

James Pinfold

A big concern for astronomers—amateurs and pros alike—is light pollution. Gazing at the stars gives us important knowledge about our place in the universe. Without that, we lose perspective.

But some might say, you know, there’s so much up there that we can’t see anyway. What can’t we see? and why we can see what we can? —those are questions Trevor Chow-Fraser had. Luckily there was a world famous particle physicist at the observatory that night. Thank your lucky stars! James Pinfold is a founding member of the ATLAS experiment and the spokesman for the MoEDAL experiment, both taking place at the Large Hadron Collider in Switzerland.

A Canadian Star Comes Back to Earth

Most of us will never know what it’s like being in space. We’ve all seen the pictures of that familiar, glowing blue and green orb out the window of a spaceship. We know what the that golden crescent we see in the sky every night really looks like. We have rich imaginations and an ages long fascination with what could be out there beyond the sky. But what does space smell like? What does it really feel like to know the vastness of it all? Our own Matt Hirji talked with Commander Chris Hadfield to try and understand questions like these.

Terra Informa at Night

This week, a re-broadcast of  one of our favourite episodes: Terra Informa at night! Listen in for stories about light pollution and sustainable lighting, life on other planets and night photography, plus the beauty of wandering outside at night. We recorded this on-site last November, outside the Telus World of Science Observatory, and the Queen Elizabeth II Planetarium in Coronation Park, Edmonton, Alberta.

Light Pollution/Sustainable Lighting

Star light, star bright. What is night without darkness? As cities grow bigger, our nights grow brighter.What is light pollution? How are industry and municipality incorporating light efficient design? Kathryn Lennon spoke with Alan Luck, Energy Engineer at Shell’s Scotford Upgrader, in Strathcona County, Alberta, and Sherrilyn Jahrig, Director of Light Efficient Communities and Beaver Hills Dark Sky Preserve Coordinator for the Royal Astronomical Society of Canada.

The Fermi Paradox i.e. Counting the little green men & big blue planets

Paul Gilster enjoys one of the most unlikely of day jobs: writing full-time on the science of space travel as the lead journalist for the Tau Zero Foundation. You can find his nearly daily updates on the website Centauri Dreams. Trevor Chow-Fraser got in touch with Paul to help us understand one of the central mysteries of outer space, the question we’ve all had at some point when looking up at the stars—are we alone in the big vast universe? Or, is there life up there in the stars? And if so, well why the heck haven’t they come calling? That’s the question scientists call the Fermi Paradox.

Night Photography

To get a sense of the wonder of being outside at night, we called photographer Yuichi Takasaka in Lumby, BC. His pictures of wildlife and the night sky helped build momentum to declare Jasper National Park a designated dark sky reserve. Takasaka is also one of the photographers behind The World at Night, a collaborative international effort to capture the night sky.
