A new hypothesis from Columbia University astrophysicist David Kipping suggests humanity’s first sign of alien life won’t be a greeting For most people, the idea of alien contact has been shaped less by astronomy than by cinema. Films have taught us to expect intention: visitors who arrive either with open hands, as in E.T., or […]

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 […]

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 […]

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 […]

Whether it be with naked-eye viewing, through a pair of binoculars, or with a beginner’s telescope, a certain amount of planning can make way for viewing enthusiasts to fully enjoy the spectacular events that take place in the sky in 2026. Be it eclipses, aligned planets, or an eight-year supermoon, there are plenty of spectacular […]

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, […]

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 […]

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 […]
