I have spent 23 years documenting the global LED transition of city lighting from space. Across my 4 missions to the ISS, I have photographed every major city on Earth, building a data set of the gradual replacement of sodium vapor lighting with LEDs. The warmer, yellow-orange of gas discharge lamps has been phased out worldwide to multi-colored LEDs, citing energy savings and environmental reasons. Widespread adoption has markedly changed the way our cities look from orbit, and as many have pointed out, how they feel to those on the ground! Here is a collection of the most striking before-and-after photos I have observed:
Miami, Florida as seen from the ISS in 2025. This city has changed tremendously since my previous mission, replacing its yellow-orange sodium vapor lights with multi-colored LEDs. The city grid really pops! This LED takeover of city lighting is world wide.

I finally have all 1.2 million raw image files from my latest mission to ISS! Here is a sample of one of my favorite Milky Way photos, taken from the Cupola with Nikon Z9, Arri Zeiss 15mm lens, T1.8 with custom sidereal drive that cancelled out star motion relative to our orbit.

Orbital star trail marked by Starlink satellites, appearing in groups of streaks across time exposures when their solar panels reflect sunlight. 10 years ago such flashes from the Iridium constellation, then one of the largest, were a rare occurrence. Now we see them frequently!

Soon... full moon! The next full moon will light the night skies on Sunday, May 31. If you've ever wanted to take a great picture of the Moon, check out our Lunar Photography Guide for tips and tricks: science.nasa.gov/moon/photog…

Our TESS telescope has released its most complete view of the starry sky yet! All those dots? They're confirmed and candidate planets! Since launching in April 2018, TESS has been scanning wide swaths of the sky to build up this mosaic. go.nasa.gov/49MK9hU

The Pentagon has released materials on UFO encounters. 162 files have been released to the public, including images and videos of "UFOs," testimony from experts and astronauts, and unknown atmospheric phenomena that have also been attributed to UFOs. For example, the video shows an unknown star-shaped object rapidly moving across the sky in a zigzag pattern—the Pentagon military was unable to identify it. View the full archive on the official website.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

5 years ago today: NASA's Ingenuity Mars Helicopter made the first powered flight on another planet. 🚁 Over the course of 72 flights and 3 years, it soared higher, faster, and farther than ever envisioned. go.nasa.gov/3JrXDSQ

Orion's main parachute has deployed. The spacecraft has a system of 11 chutes that will slow it down from around 300 mph to 20 mph for splashdown. Get more updates on the Artemis II blog: nasa.gov/blogs/artemis/

A galactic hit-and-run! The galaxy NGC 4485 shows signs of an interaction with a bypassing galaxy, but it didn't cause destruction. In fact, it triggered a whole new generation of stars to form! Find out more: go.nasa.gov/4cfAx0T

Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using @chandraxray. READ MORE >> go.nasa.gov/4dQ6uyc

One week in the solar system 🪐 Even as @NASAArtemis II was making its historic trip to the Moon, several other @NASA missions were exploring all across the solar system. Here are just a few of the images some of them captured during one week science.nasa.gov
