Interstellar objects usually pass through quietly, noticed only by a small group of astronomers before fading back into deep space. Comet 3I/ATLAS has followed a different path. Even as it moves away from Earth and heads out of the solar system, it keeps offering scientists new details to puzzle over. Recent observations suggest this visitor…

Photographs taken from directly above the Pacific Ocean have shown large areas of red light emitted against the backdrop of the surrounding environment, enough to rival the scale of a large city. These images, taken by pilots and circulated on the internet, raise questions about whether this phenomenon could be a product of the atmosphere,…

Radio waves from Earth have been moving through space for more than a century. They did not start as part of any grand plan to reach the stars. They began quietly, as a new way for humans to speak across oceans. Since then, those signals have continued outward, spreading slowly into space at the speed…

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….

Every year, the southwest monsoon event changes India’s river systems. The changes include turning one of India’s rivers red. The effect is associated with increased rainfall. The changing colours of India’s rivers are closely linked with the monsoon. The monsoon is associated with changes in India’s climate. The changes in India’s rivers are linked with…

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….

A world in warming, under most circumstances, tipping toward deep cooling does seem counterintuitive; yet, Earth’s geological record is replete with such episodes when rising greenhouse gases were followed by abrupt climatic reversals. Today, scientists increasingly look to the oceans for an explanation, where the quiet work of microscopic organisms regulates the exchange of carbon…

Most of the time, people never question the colour of water. It feels invisible in a glass, like air you can drink. Then a holiday comes around, someone stands by the sea, and suddenly the water looks blue or green or something in between. It’s the same substance, yet it behaves differently depending on how…
