Astronomers noticed something odd while reviewing radio data from distant space. Three bright signals appeared close together. At first, it looked like a coincidence. It was not. Each signal came from the centre of a different galaxy. All three galaxies were interacting. The result stayed the same. Each galaxy contained a supermassive black hole that […]

Planetary systems begin in chaos. In their primitive form, many rocky and icy objects are careening through space, smashing into each other, breaking apart, and accumulating to form planets, moons, asteroids, and comets. For many decades, planetary scientists assumed this “history of violence” ended abruptly after a relatively quick passage after planets achieved stable orbits. […]

The cave is low and dark, and it is dug into limestone on a little island in the Baltic Sea where the wind blows salt from all directions. For thousands of years, humans used this spot to be safe while they hunted seals and fished in the ocean. The trash they left behind was normal. […]

The Red Sea is a narrow stretch of water that runs southeast from Suez in Egypt for about 1,200 miles (1,930 km) all the way to the Bab el-Mandeb Strait, which links it to the Gulf of Aden and then the Arabian Sea. It separates the coasts of Egypt, Sudan, and Eritrea on the west […]

A piece of space debris is the focus of the closest attention of astronomers worldwide as scientists evaluate a rare, but very dramatic, option. A collision of asteroid 2024 YR4, approximately 60 metres long, with the Moon in December 2032 could result in an impact visible from Earth due to the enormous force. Researchers, however, […]

Space looks dark and cold from Earth, but sunlight beyond our atmosphere is harsh in ways most of us never experience. Without air, clouds, or an ozone layer to soften it, solar radiation hits with full force. That raises a simple, almost playful question that hides a serious concern: do astronauts need sunscreen in space? […]

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more subtle manner. Instead of moving people or objects through history, researchers are investigating whether it is possible to reverse physical processes themselves. Recent advances in wave physics hint that, under the right conditions, time can […]

The spirit of Christmas is here, gifts and wishes are pouring in, and the joy of the holidays has taken over. Amid the choirs and carols of the holiday, Nasa shared its celestial greetings, celebrating the day.The cosmic tree from the nebula group NGC 2264, formed with a cluster of stars emitting blue and white […]

Deep down, beneath the icy edges of the Greenland Sea, a remarkable and previously undiscovered geological and biological complex has been found by scientists. The existence of this topographic anomaly deep down in the sea, where light, high pressure, and low temperature are prevalent factors, extends our understanding of what is known about the oceanography […]

It does not look like a breakthrough at first. Just the faint outline of a foot, pressed into what was once soft ground and later hardened by time. No bones nearby. No tools neatly arranged. And yet this single footprint, found in southern Chile, may be one of the most important human traces ever uncovered […]
