In case it’s escaped your attention, there’s been a surge of interest in aurora just recently after a powerful geomagnetic storm — caused by a huge blast from the sun — reached Earth at the beginning of this month.
Aurora occur when charged particles from the solar wind interact with Earth’s magnetic field and atmosphere, leading to the formation of spectacular ribbons of light in the upper atmosphere. The best place to view aurora are from locations within or close to the Arctic Circle, with parts of Norway, Sweden, and Canada particularly famous for offering stunning views.
The International Space Station (ISS), 250 miles above Earth, is also an ideal spot to view the dramatic light show, although admittedly the facility is out of bounds for most of us.
One lucky inhabitant, NASA astronaut Anne McClain, has just shared a breathtaking video (below) showing an aurora burst into life as the space station orbited Earth.
“Auroras from space always draw crewmembers to the Cupola,” McClain said, referencing the seven-window module that offers the station’s best views of Earth and beyond. “I love how this one illuminated our Dragon [spacecraft], and I also love the dance of satellites on the left in the latter part of the video. It’s interesting how the aurora creeps along the top of the atmosphere as it comes up over the horizon.”
Having witnessed the sublime beauty of this particular aurora, McClain said that she’s now “added traveling to see auroras from Earth to my bucket list!”

NASA astronauts staying aboard the ISS for up to half a year are pretty much guaranteed to witness at least one aurora. For many of them, it can be the most memorable moment during their time in orbit.
Jasmin Moghbeli, who returned from the ISS last year, said after witnessing an aurora: “Every single time I’m amazed at how alive and beautiful our planet is.”
And check out this remarkable image of an aurora, captured in 2023 by the now-retired NASA astronaut Scott Kelly, who described the phenomenon as “absolutely unreal.”
After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
