A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself.
This effect is known as frame-dragging, or the Lense-Thirring…

In the quarter century that humans have lived and worked aboard the International Space Station, astronauts and visitors from around the world have celebrated countless holidays more than 250 miles above Earth while traveling 17,500 miles per…

What was your skywatching highlight of 2025? A comet becoming visible to the naked eye? Mars disappearing behind the moon? Or did you glimpse a “blood moon” total lunar eclipse and see the northern lights at last?
Here’s what happened in the…

The Milky Way, our home galaxy containing 100-400 billion stars, was bright and vibrantly visible from Florida earlier in 2025.
Earth sits along one of the galaxy’s spiral arms, about halfway from the center, according to NASA.
While the Milky…

KIM24 initially sampled a total of 109 ingroup taxa and 3 outgroup taxa for their phylogenetic analysis2. However, in their divergence time estimation using MrBayes 3.2.62, a program limitation restricted the retention of only a single outgroup2….

After decades of steady progress, computational astrophysicists have reached a major turning point in black hole research. A new study presents the most detailed and complete model yet of luminous black hole accretion, the process by…

With the widespread use of plastic products, a large amount of microplastics have entered soil ecosystems, leading to a continuous decline in soil environmental quality and posing unknown risks to both the environment and human health.

Contrary to what Pink Floyd say, there is no dark side of the Moon. The Moon rotates on its axis once every orbit around Earth, and so, like us, experiences day and night periods (albeit very protracted).
But this tidal locking does mean that one…
