The iPhone Duo has already inspired so much creativity. Proud that Living Earth is part of @MacRumors' roundup, alongside a seriously creative bunch. Fold & Squish, Tiny Computers and Orisuji are favourites. 🌍
Check them out:

Happy iPhone Duo day! Living Earth is optimized for iPhone Duo. Get it on @AppStore apps.apple.com/us/app/living….
Took @livingearthapp for a spin on iPhone Duo. That inner display was made for this!

I made a marble game for iPhone Duo where the hinge is the controller. You fold the screen to tip the board and roll the marble home. Every world adds a new way to use the fold.
Marbles Unhinged is up for pre-order now and launches Friday, Oct 23.

Armchair astronauts, get ready to unfold iPhone Duo. Living Earth is coming with a planet that spreads across the whole inner display, sharper clouds, and a zoom that goes from orbit to the coastline. #iPhoneDuo
Spain's total solar eclipse tonight. I captured the Moon's umbra sweeping through Spain's Cantabrian Mountains at 8,400 km/h (5,250 mph). #totalsolareclipse #tse2026 #spain
Comet Lemmon passing close to Earth.
I shot this at 135mm f/2, 13x60s exposures for a total of 23m exposure time.
The comet is becoming naked-eye visible and is getting brighter until early November, when it’s closest to the Sun. It’s very photogenic through the camera!

So Apple has introduced a new system called “Private Cloud Compute” that allows your phone to offload complex (typically AI) tasks to specialized secure devices in the cloud. I’m still trying to work out what I think about this. So here’s a thread. 1/
Vision Pro is an incredible way to view photography. I turned two of my Milky Way images into massive 200-megapixel high-res panoramas.
I've made two to download. Add them to the Photos app & they’ll be in the Panoramas tab. we.tl/t-hte5Q2zJGy

I shot the "green comet" (C/2022 E3) that's been in the media recently. It makes its closest approach to Earth on Wednesday, Feb 1st. A two-hour exposure shows the greenish glow from carbon gas and a rarely seen antitail.

The iconic Horsehead and Flame nebula. I did over six hours of exposure around Alnitak, the left-most star in the belt of Orion. I love the colors and detail in this area of sky.

Over six hours of exposure at the Pleiades star cluster, aka The Seven Sisters. Imaged over Thanksgiving week in the Mojave Desert. The blue nebulosity is from the light of the stars passing through a cloud of dust and gas in the interstellar medium.

Nature makes the best fireworks. Shot this last year, 3.5hrs exposure. 25 million light years away and its name is literally "Fireworks Galaxy". #astrophotography #astronomy
Testing out some urban #astrophotography. Rosette nebula in monochrome shot from backyard in San Francisco. Using narrowband filters (H-alpha) to knock out most of the light pollution.

① Hello. I'd like to share my favorite Nintendo secret.
It starts with the Famicom Disk System, which was, by all accounts, a very important system but a total commercial failure.
When you boot it up, you're greeted with this energetic, very Nintendo fanfare: (Sound on!)
The sophistication of this no-click iMessage exploit is incredible. Attacker creates a Turing-complete virtual machine out of old image compression format to execute - no interaction required on victims end. Used to target dissidents. Nothing is safe.🤯

What 158,000 miles per hour looks like. #CometLeonard travelled over 316,000 miles in this two hour time-lapse I shot last Friday morning as it sweeps past globular star cluster M3. #C2021A1 #astrophotography #timelapse
