Sonnensystem: Saturnmond Mimas scheint einen Ozean zu besitzen

Bisher galt Mimas als einer der Eismonde des Saturn. Einen Ozean hatte man dort nicht erwartet. Neue Forschungsergebnisse deuten jedoch auf einen jungen Ozean tief unter einer Eisschicht hin. Ein Bericht von Patrick Klapetz (Astronomie, Wissenschaft)

Daily Telescope: A solar eclipse from the surface of Mars

From Mars, with love.

Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's February 12, and today's image is a real treat from the surface of Mars.

In it we see the larger of Mars' two moons, Phobos, passing in front of the Sun. NASA's Mars Perseverance rover acquired this image using its Left Mastcam-Z camera, one of two powerful cameras located high on the rover's mast. It was acquired on February 8, 2024 (Sol 1056). Phobos is rather small, with a radius of just 11 km. But since its orbit is less than 10,000 km from the surface of Mars, it still appears rather impressive against the distant Sun.

I was wrong to ignore Zigbee and Z-Wave. They’re the best part of my smart home.

There’s plenty of room for this early-aughts tech in a modern connected space.

I've set up dozens of smart home gadgets across two homes and two apartments over the last five years. I have a mental list of brands I revere and brands from which nothing shall ever be purchased again. In my current abode, you can stand in one place and be subject to six different signal types bouncing around, keeping up the chatter between devices.

What can I say? I'm a sucker for a certain kind of preparedness and creativity. The kind that's completely irrelevant if the power goes out.

When I started at Ars in the summer of 2022, the next generation of smart home standards was on the way. Matter, an interoperable device setup and management system, and Thread, a radio network that would provide secure, far-reaching connectivity optimized for tiny batteries. Together, they would offer a home that, while well-connected, could also work entirely inside a home network and switch between controlling ecosystems with ease. I knew this tech wouldn't show up immediately, but I thought it was a good time to start looking to the future, to leave behind the old standards and coalesce into something new.
