Scientists have detected ripples in space-time from the violent collision of two massive black holes that spiralled into one another far beyond the distant edge of the Milky Way. The black holes, each more than 100 times the mass of the sun, began circling each other long ago and finally slammed together to form an even more massive black hole …

Behold! The 2025 ZWO Astronomy Photographer of the Year Awards shortlist has been released, showcasing a spectacular array of astrophotography images ranging from solar prominences and auroras to distant galaxies and beguiling nebulas. For the past 17 years, the Royal Observatory Greenwich — supported by astronomy camera maker ZWO — has called on the global photography community to compete in …

Humans have built so many dams around the world that the Earth’s poles have wandered away from the planet’s rotational axis, new research suggests. Over the last 200 years, humans have constructed nearly 7,000 massive dams, impounding enough water to nudge the Earth’s poles by about three feet (one meter) and cause a 0.83-inch (21-millimeter) drop in global sea levels, …

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein’s theory of general relativity. Published in 1915, and already widely accepted worldwide by physicists and mathematicians, the theory assumed the universe was static – …

Disaster victims trapped beneath the rubble of a collapsed building or mine may one day be rescued by a tiny and unlikely savior: a beetle with a backpack. Researchers have made major strides in cyborg technology, creating a breed of cyborg beetles that can climb walls, obstacles, and sloped surfaces while being remotely guided by a video game controller. Called …

In a world where towering waterfalls like Niagara Falls and Angel Falls capture our imagination, there is one waterfall so vast, yet hidden, that it dwarfs all others. Found beneath the cold waters of the Arctic, the Denmark Strait cataract, Earth’s largest waterfall, is a natural wonder that no human eye has ever seen in its full, mighty descent. Stretching …

The Perseids will be active from Thursday, July 17, through Saturday, Aug. 23 and will peak this year on Aug. 12 and 13. But the …

Paleontologists have unlocked a groundbreaking discovery that brings clarity to the evolutionary history of rhinos. A recent study, published in Nature, reveals how ancient protein sequences recovered from the fossilized tooth of Epiaceratherium sp., a rhinocerotid from the Early Miocene period, are transforming our understanding of this species’ past. These ancient proteins, preserved for over 24 million years, have not …

A 140,000-year-old skull discovered in Skhul Cave on Mount Carmel, Israel, may represent one of the most significant findings in human evolutionary history. According to a new anatomical analysis, the cranium likely belonged to a 5-year-old girl whose parents came from two different human species: Neanderthal and Homo sapiens. Clues Hidden in Ancient Bones First unearthed in 1929 during early …
