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

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.🤯 googleprojectzero.blogspot.com/2021/12/a-deep…

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!)

Welcome Laura! Love this series of surreal multi-layered landscapes. 👇

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.

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

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. #astrophotography #astronomy

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. #astrophotography #astronomy

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. #astrophotography #CometZTF #comet

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 #AppleVisionPro

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/

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!
