Greenland’s ice-covered landscape looks like an immovable block on satellite maps. Yet the story locked beneath its center suggests a very different past, one that places future coastal cities in a tight spot. During the Pleistocene – the geologic chapter that began about 2.7 million years ago and ran through innumerable swings between cold and mild – the island’s ice waxed and …

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to reach our own detectors here on Earth.  Today, the LIGO Collaboration …

Image by Yihan Wang via Pexels According to The Conversation, a new study published in Physical Review D challenges the common idea that the Big Bang was the start of everything. Instead, researchers suggest it might have been a rebound—a bounce—after a huge gravitational collapse forming a black hole. This “black hole universe” idea uses everyday physics to rethink cosmic …

NASA’s Parker Solar Probe made history with the closest-ever approach to the sun last December, and we’re finally getting a look at some of the images it captured. The space agency released a timelapse of observations made using Parker’s Wide-Field Imager for Solar Probe (WISPR) while it passed through the sun’s corona (the outer atmosphere) on December 25, 2024, revealing …

When the first Neanderthal bones were uncovered in 1856, they sparked a flood of questions about these mysterious ancient humans. Were they similar to us or fundamentally different? Did our ancestors cooperate with them, clash with them, or even form relationships? The discovery of the Denisovans, a group closely related to Neanderthals that once lived across parts of Asia and …

On July 2, NASA revealed the existence of 3I/ATLAS, only the third ever interstellar object observed in the universe. These are objects that exist in interstellar space—the areas between stars—and which are not gravitationally bound to any star. The two other interstellar objects discovered to date are the comets 1I/ʻOumuamua and 2I/Borisov. 3I/ATLAS was discovered on July 1, when its …

A new study published in iScience reveals intriguing insights into the evolutionary origins of mammals through the detailed analysis of 380-million-year-old lungfish jawbones found in the Gogo fossil field, located in northern Western Australia. This cutting-edge research offers a unique glimpse into the predatory habits of ancient lungfish and their significant role in the transition from aquatic to terrestrial life. …
