I'm sorry. I'm I'm Astronomycast, Episode 771, Comet Tales.

Welcome to Astronomycast, our weekly facts-based journey through the cosmos,

where we help you understand not only what we know, but how we know what we know. I'm Fraser Kane.

I'm the publisher of the universe today. With me, as always, is Dr. Pamela Gay, Senior Scientist

for the Planetary Science Institute and the Director of Cosmo Quest. Hey, Pam, how you doing?

I am doing well. I am very envious of the

amazing adventure you're about to go on it sounds so cool yeah we're going to do a month in

thailand so not for any purpose but to escape the canadian winter and and we are about to record a bevy of shows.

And so there's going to be very boring intros because we're just going to sit and do them.

How are you doing?

I don't know how I'm doing because I've recorded this in advance.

I have to assume that I'm fine.

So, yeah. I saw an elephant. I went to a temple. I ate some really tasty Thai food. I don't know. I don't know. With the arrival of Comet 3-E Atlas, the world is getting a crash course on comets, their behavior, and of course,

their tails. Today we're going to talk about comets in their tails. Why they exist, how they

grow, why they can be different colors, and how they can sometimes point at the sun. And we'll

talk about a second, but it's time for a break. And we're back. So I've ranted quite a bit on my channel about how awesome Comet

3A Atlas is. Yes. And my frustration at the nonsense that is proliferating on YouTube.

And there is a lot of nonsense. You know, on the, on the, on the, the best case, you have people who are

writing scientific papers that are, go against the scientific mainstream and much to the

eyebrow raising of their scientific colleagues, not naming any names, pointing any fingers.

And on the worst case, you've just got people making stuff up, just literally going,

it broke into 17 pieces, and now we've got spaces that are flying out of it and laser beams
