Chapter 2: What surprising solar system discovery did astronomers make?
Happy, happy Friday. It's the last show. You'll learn a lot of things on the show tonight. Here are some of them. What if you could hack your own dreams, sort of like using a cheat code at a video game to solve problems while you sleep? In 10 minutes time, we'll tell you about how scientists figured out how to plant ideas in your dreams to boost your creativity. Yes, it's basically inception.
Then after that, some research that flips the script my mother told me about cannabis. In an admittedly narrow research study with patients with bipolar disorder, moderate cannabis use actually sharpened people's decision-making.
Now, the science is nuanced, maybe a little controversial, and definitely not a green light to go green, if you know what I mean, but we'll tell you about that study halfway through the hour. Those are some of tonight's topics, but let's start off with some science news. Far, far away in a planetary system that has astounded astronomers exists some planets that are breaking our brains.
We're going to discuss them here with astrophysicist and professor Jesse Rogerson from York University. Jesse, I love doing science news with you. Thank you for being on the show.
You're welcome. I love doing it, too. You ready to talk some science?
I am, and I love space.

Chapter 3: How can exercise alleviate depression and anxiety?
That's my jam. I always loved planets. I remember when planets were first discovered outside of our solar system when I was a kid and it blew my mind. Now we've mapped out tens of thousands of them and they are weird, some of them.
Yeah, 1995, that was the first official planet found around a sun-like star, 51 Peg B. 1995, it's a brand new field. And since I think the number is somewhere in the sixth, I don't know if it's 10,000 yet. I think it's 6,000 planets. And up until 1995, all we had was our solar system to go by. And there was this hypothesis, which is really a theory now, of how the solar system formed.
Chapter 4: What role does cannabis play in decision-making for bipolar disorder?
It formed from a big gas cloud that collapsed down into a star, flattened out into a disk around it, and the planets formed inside. And this theory on how our solar system formed explains some really important things about our solar system, like why our solar system is flat, for example. You know, it's great. I literally just taught this in my astronomy class.
Cool. I remember being nine years old. And I mean, we did have one thing going for us before 1995, because at that time, Pluto was still a planet. So there is some loss, but what the gain was, is this discovery.
Chapter 5: Why did a veterinarian prescribe a tiny blue pill for a dog?
Anyway, let's talk about this solar system, planetary system, what, some hundred plus light years away from Earth. So kind of our neighbor in galactic scales or universal scales. Yeah. These planets are orbiting a red dwarf star named LHS 1903. Tell me about what makes them so weird and why astronomers are so puzzled by this system.
So when you look at this system, so red dwarf stars are the most common type of star in the universe. So you expect to find planets around them. And there's both rocky and gassy planets around this star, just like we have rocky and gassy planets. But the order is confusing. Here in our solar system, we have the inner rocky ones.
Chapter 6: How do pets influence criminal justice outcomes?
Mercury, Venus, Earth, Mars are rocky planets. They're close to the sun. And then you have the gassy ones, Jupiter, Saturn, Uranus, and Neptune, and they're far from the sun. And that is easily explained through like a temperature gradient where close to the star, it's hotter. And things like gases and volatiles like ices don't really like being near hot things.
And so planets that are made of gases form farther away from the hot thing. That's a pretty standard approach to planetary formation.
Because if Uranus existed close to the sun, we would have a hot gas problem. Sorry, that's a different interview that I do on the show. Okay, so the kind of like structure or composition of planets kind of makes sense.
Chapter 7: What alarming trends are revealed in sexting among teens?
Rocky ones close, big gas ones far away. This is kind of our picture of what star systems should look like with planets.
And this one throws that out the window because they found the order went rocky planet close to the star. The next planet out is a gas planet. Then the next one is a gas planet after that. But then after that, the fourth planet is another rocky one. Which is totally confusing in your like nebular theory idea where rocky planets close and gas planets far.
So it kind of threw them for the loop and the researchers were trying to figure out what to do with this. They thought maybe it could be that that fourth one way out there originally started as a gas planet, but through some sort of like dynamics, like collisions or interactions, it lost its big envelope of gas. But they couldn't make that work.
Chapter 8: Are dating apps really optimizing for love or profit?
So what they came down to was maybe it just, because it's a small system with a small star, maybe that planet way out there at the edge just formed in a gas-depleted area. Basically, the two middle planets that are gas planets sucked it all up. And so that fourth one couldn't pull gas on, and it just stayed rocky. which is an interesting theory. I don't know.
It's tough to say if it's true or not because we're in this golden age of exoplanets where there's so much weird stuff and it's really hard to pull it under one envelope right now.
Now, ever since I saw that 2011 movie, Melancholia, it's a really good movie. It sort of explores people's depression and broken lives. Yeah, I love that movie. But at the end of the movie, a rogue planet, a planet from outside our solar system, I guess with an eccentric orbit or whatever, hits Earth, and that's the end of it. Everyone dies. Could this planet be a captured rogue planet?
A planet that wasn't bound to a star gravitationally, that just kind of wandered in and then got sucked into orbit around this star? Or is your answer, I'm not sure.
No, that's a good question. I would say probably not. I didn't investigate that, but the way we would know is looking at the orbit. So when planets form naturally around a star, they're going to be usually in pretty circularized orbits. But a planet that's captured would not be part of the flat plane and would not be in a nice circular orbit.
It would be like in a random elliptical orbit on some random orientation. And if that's the case, then it could be captured. But they made no mention of that in the paper. I imagine it's... obliquity it's like inclination to the plane is probably pretty standard so it's it's probably from the they probably check that i would bet
All right, well, since we're doing general science news, let's completely change courses outside of this star system and look at a habit that can ease people's depression and anxiety systems. Symptoms, not systems. Tell me about it.
This was from the British Journal of Sports Medicine, where they were looking into people affected by depression and anxiety. And how best to treat that through exercise-based therapies. So this is a meta-study. In fact, it's actually a meta-meta-study.
In science, a thing called a meta-study is where a group of researchers go into the literature and find all of the studies that have already been done by other researchers and take a look at all of those results and look for patterns. Very important things to be doing, meta-studies. This study was a meta-study of meta-studies about depression and anxiety, if you're following me.
