I‘m still in ChatGPT (macOS app) land, without direct integration etc. How do you feed the AI your set of guidelines?

The Tanagra fragrance is hilarious, my all-time favorite 🤣🖖

But there‘s hope, as long as some parents raise their children to think about the greater good. Everyone should be reminded that Earth could be the only planet that features life, maybe in our galaxy, maybe even in the local group. Although I crave for another solution to the Fermi Paradox… 🌍

Finally! I‘ve been waiting for it since watchOS 1 😁

Congratulations, fellow Austrian developer 🥳🥇 The thought that you might beat the Apple Design Awards game once again crossed my mind when I played it for the first time. Really well done 👏

Maybe it’s Kelvin and these numbers are far too low? Wait, there was another scale over there… something with F… 😜

Oops I overlooked the renewal reminder 🫢 Fixed in this universe, thanks! 🖖

These are real images of exoplanets.

Four super-Jupiters, imaged 10 times over 12 years around a star 133 lightyears away.

These are real, giant worlds, out there in the dark.

And we can see them.

A or C for me… I think A looks a bit cleaner.

Saturn Gains 128 New Moons, Bringing Its Total to 274 (Gift Article) The objects around the ringed planet are tiny, but some of them may have formed relatively recently in the solar system’s history.

Somewhat ridiculously, Saturn now has 128 new moons, bring its total to 274.

These are mostly tiny rocks, a few miles across, that orbit the planet backwards – but they might be evidence of a recent smashup in the planet's orbit.

Enceladus might have a subsurface ocean beneath the icy crust, which makes it a prime target in the search for extraterrestrial life. Its cryovolcanism ejects plumes of water vapor, ice particles, salts, and organic compounds – what more do you need to cook up friendly microscopic aliens? 👽
