Eyeball Planets, Lobster Oceans? Studying Exoplanet Climates

Image
Headlines about an "eyeball planet" got my attention last month. Then I got distracted by what I thought were more time-sensitive topics — and remembered what two scientists learned when they simulated ocean currents and winds on a tidally-locked exoplanet. That last item was from 2013. It's still the best discussion I've seen of what an "eyeball planet" might actually look like. Turns out that a patch of open ocean on a tidally locked exoplanet's ocean wouldn't necessarily be circular. But I'll admit that "eyeball planet" is a cool description. And may be easier to remember than terms like "lobster-like spatial pattern". So this week I'll be talking about LHS 1140 b, which may not be an "eyeball planet" after all, ocean planet simulations; and — briefly, for me — how I see extraterrestrial life. LHS 1140 b: Water, With Nitrogen in the Atmosphere — Maybe Tidally Locked Ocean Planets: Simple, and Not-So-Si

Hurricane Beryl: Sort-of-Good News, and Taking the Long View

Folks living in the Caribbean, Yucatan Peninsula, and south Texas are cleaning up after Hurricane Beryl. Some are also mourning those who didn't survive the storm. I haven't been personally affected by Beryl, although my in-laws are in Louisiana, next state over. They seem to have been away from the worst weather, for which I'm grateful. This week I'll take a quick look at what happened, what the storm doesn't mean, and — as usual — whatever else comes to mind.

(Beryl stopped being a hurricane July 8, 2024. By then it had broken several records. I look at Beryl, and what we are learning about tropical cyclones.)
