It may not be as dramatic as a total solar eclipse, but there’s something equally epic about watching Earth’s shadow gradually engulfing and coloring the moon during a total lunar eclipse. The next total lunar eclipse — colloquially called a “blood moon” — will occur on Sept. 7-8, 2025, but it won’t be another 177 days until the phenomenon is visible from parts of…

Nikon Stabilized 12x25 S binocular review
September 3, 2025
The Nikon Stabilized 12×25 S binoculars are my top recommendation for a compact binocular with image stabilization built in, all for under $650. It was back about three years ago in a previous review of the Nikon Monarch HG 10×42 binoculars that I yearned for Nikon to release image stabilized binoculars, and thankfully, just a few years later, that wish has been fulfilled.
They are…

Official death count of 2023 Hawaii wildfires doesn’t capture true toll, study suggests
September 2, 2025
In August 2023, the deadliest fires the U.S. had seen in a century tore through Lāhainā, Maui, devastating the town and taking the lives of between 100 and 102 people, according to an official death count at the time — and, as the planet warms and the climate changes, scientists expect wildfires to grow in number.
Now, two years after those tragic Lāhainā wildfires, researchers have taken a…
Scientists discover explosive origins of superspeed electrons streaming from the sun
September 2, 2025
The joint European Space Agency (ESA) and NASA Solar Orbiter spacecraft has tracked electrons traveling at nearly the speed of light back to the sun, finding they originated in different types of solar outbursts.
Solar Orbiter detected these so-called Solar Energetic…
To resolve nearby Earth-like exoplanets, a new telescope design that is rectangular rather than circular may be necessary, according to a new study that explores what the next great space telescope might look like.
“We show that it is possible to find nearby…
Galactic cannonballs: The mystery of hypervelocity white dwarfs may just have been solved
September 1, 2025
White dwarfs — the superdense, slowly cooling embers left behind when stars like our sun die — are usually quiet cosmic relics. A rare few, however, are anything but.
In recent years, astronomers analyzing data from the European Space Agency’s Gaia spacecraft identified a handful of white dwarfs hurtling through the Milky Way at breakneck speeds of up to 1,240 miles per second (2,000…
