Universe Today

...

this is something that I went through with Universe Today.

I got to this exact same point about 18 months ago, where the advertisers were just getting worse.

The amount that they were giving in terms of revenue was going down.

I lost, like, 80% of my ad revenue on Universe Today because of this ratchet.

And then you've got the rise of all this AI slop.

You've got the search engine optimization.

Welcome to Astronomy Cast, 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 Cain.

I'm the publisher of Universe Today.

With me, as always, is Dr. Pamela Gay, a senior scientist for the Planetary Science Institute and the director of CosmoQuest.

The light sail hypothesis for 'Oumuamua was first presented by Avi Loeb in late September in a Scientific American article.

A month later, the Bialy and Loeb paper appeared on the preprint archive, and a few days after that Centauri Dreams and Universe Today wrote about it.

Over the next couple of weeks, many media outlets picked up the story.

Some of those articles were measured and some were even critical, but most were giddy at the possibility that we'd discovered an-

It's the 365 Days of Astronomy podcast, coming in three, two, one.

Today we're starting a new series of episodes, the Universe Today News.

Today I'm recording Lawrence Tognetti's Seven-Stage Journey Reveals How Falling Space Rocks Survive Air.

At least once in our lives, we've all seen a bright streak of light briefly blaze across the sky and have quickly referred to it as an asteroid, a meteor, shooting star, comet, or some other whimsical name we've heard others use to describe it.

there is a nice piece on, uh, our old friend Universe Today.

Uh, they've got a nice piece on it called NASA Announces Next Steps For Swift Rescue Mission, and it g- has a lot of quotes from, uh, people like, uh, the NASA administrator, Jared Isaacman, uh, and, and other people involved.

Uh, Catalyst Space have released a statement, um, all of which is, you know, basically saying that they, they'd, they, they'd hope for more science from Swift.

Um, uh, so, uh, I, I found this interesting to think about.

Uh, one of the more recent models for this was outlined in Mark Thompson's A New Theory Explains the Surprising Origin of the Planet Mercury, published in Universe Today, uh, last year, uh, covering a paper from the National Observatory in Brazil.

Uh, so this is one of those things where, you know, m- scientists will, will con- will put together different models trying to figure out exactly, like, how this would work from a physics standpoint.

Uh, but yeah, the, o- on one hand, either the planet forms and it gets, uh, it gets all this extra lighter stuff blasted off of it-

And sometimes it's just a break from my routine, but other times it introduces me to the reality that I don't have to get stuck in routines that aren't working.

In an article from universetoday.com, they talk about how chaotic systems are everywhere.

It's one of the reasons the weather is so hard to predict.

It's not just because it's complex, with lots of forces and interactions and particles involved.
