Dangerous satellite air pollution exists in a legal loophole
Air pollution from re-entering satellites is a potential environmental disaster that evades Earth-based laws, experts say.
The Sun Unleashes its Strongest Flare This Cycle
Yesterday the Sun released a huge solar flare, and it’s heading toward Earth! It’s nothing to worry about since it’s nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.

What’s the Best Material for a Lunar Tower?
Physical infrastructure on the Moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential parts of that physical infrastructure. These towers can hold numerous pieces of equipment, from solar panels to communications arrays, and the more weight they can hold in the lunar gravity, the more capable they become. So it’s essential to understand the best structural set-up for these towers, which is the purpose of a recent paper by researchers at North Carolina State University and NASA’s Langley Research Center.
What Does a Trip to Mars Do to the Brain?
It’s not long before a conversation about space travel is likely to turn to the impact on the human body. Our bodies have evolved to exist on Earth with a constant force of 1G acting upon them but up in orbit, all of a sudden that force is apparently lacking. The impact of this is well known; muscle loss and reduction in bone density but there are effects of spaceflight. Cosmic radiation from the Galaxy has an impact on cognition too, an effect that has recently been studied in mice!
James Webb Space Telescope finds supernova 'Hope' that could finally resolve major astronomy debate
The James Webb Space Telescope has observed a distant cosmic explosion that erupted in the early universe called "supernova Hope" that could help resolve lingering "Hubble trouble."

United Launch Alliance is preparing for its final planned test flight with its new Vulcan rocket in the pre-dawn hours of Friday morning. The mission, dubbed Cert-2, is the second of two missions needed before ULA can begin launching U.S. national security payloads on Vulcan.
When is the next solar eclipse?
It'll be about six months before skywatchers are treated to another solar eclipse — during which only part of the sun will be obscured from view.
