Streamed live on Sep 11, 2023. It’s official! June and July were the warmest we’ve seen since records began over a century ago. Fires are rampant across Canada, and we’re seeing record droughts around the world. Today we’re going to look at 20 years of climate science, how well does reality match up with the predictions. This video was made possibl…

In this episode, we’re going to be talking more about meteors - including the source of the Geminids meteor shower, asteroid Phaethon - as well as hot planets, hungry black holes, and how we’re working to uncover the identity of dark matter. (This episode was originally released on YouTube May 6, 2023.)…

While we could spend an entire episode on Earth, there is just too much going on in the universe to linger anywhere too long. From our world, we journey out to look at the super massive black hole in the core of M87, and then Beth Johnson will join us with an interview of the SETI Institute’s Dr Chenoa Tremblay and how radio astronomers are one ste…

This episode features the kind of news week where we looked at the April 20th eclipse in the South Pacific and decided it just wasn’t a huge priority. Between watching Starship's “will it won’t it” launch attempts and getting news of discoveries in cosmology and new software in planetary science… and the discovery of a totally weird rock formation …

For decades now, our planetary science news cycles have been dominated by Mars. Mars is relatively close, and we have a lot of experience landing there and science goals to pursue. But it has left our other closest neighbor, Venus, off the mission list. That is, until 2021, when NASA and the European Space Agency announced three separate but compli…

Humans are the ultimate pattern matchers - at least for now. I have to admit I’m looking forward to the day I can give some new AI a set of images and ask it to tell me what animals it can find among the nebulae. The software isn’t there yet… But we’re also going to take a closer look at how art and AI look at space. And also science: From looking …

Right now, humans are tantalizingly close to being able to search for life on other worlds where it is reasonable to think life could exist. We can’t do it yet - at least not in a way that would be safe for any potential life, but this is a long game, and as we’ll discuss in this episode, the technologies we need are being actively developed and te…

A new asteroid has been discovered with an orbit that crosses our own planet’s orbit. In general, this object and Earth are very good and not trying to occupy the same space at the same time, and we’ve managed to coexist for a fair amount of time. We are going to have a close approach, however, in 2046, and for the first time in a long time, the po…

We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay.

In general, the kind of year we’ll experience gets its label at the end of the year. 2005 was the year of the never-ending hurricane season. 2017 was the year we experienced an eclipse and lost Cassini. 2020 was the year satellite constellations went from a handful to hundreds of spacecraft. 2022 was the year of Mars exploration with Curiosity, Per…
