Source: Don Pettit via X (formerly Twitter) A single photograph taken from orbit has managed to make a rare visual connection between the mundane life on Earth and the vastness of the universe outside. Framed from the International Space Station, the image shows a softly glowing planetary horizon illuminated by colours of the aurora, clusters…
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…
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,…
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…
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…
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…
As NASA plans for long-term human missions beyond Earth, one question keeps resurfacing: how do you sustain life in places where resupply from Earth is slow, expensive, and limited? Machines and technology will play a significant role, but scientists are increasingly turning to biology for answers. In recent research, insects have emerged as unlikely but…
Mosquitoes target people who release more carbon dioxide, body heat and skin chemicals that signal an easy blood meal/ Representative Image If you have ever stood outside with friends and watched mosquitoes ignore everyone else while repeatedly landing on you, the experience can feel personal. Scientists say it is not. According to decades of entomology…
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…
While the term new moon is well established in astronomy, the phrase black moon is far more informal, yet it has gained steady popularity among skywatchers and space enthusiasts. A black moon does not describe a visible event in the night sky. Instead, it refers to a rare timing quirk in the lunar calendar. Much…
Earth’s relationship with space is much more complex than it used to be. Space around our planet was thought to be influenced almost solely by natural forces like the Sun and the Earth’s magnetic field for many years. But the latest studies indicate that humans have had a hand in the matter too, although it…
Artificial intelligence has already taken over large parts of modern hiring. Algorithms scan CVs, software ranks candidates, and automated systems now replace junior recruiters and even some of the engineers who once built them. CV screening, shortlisting and candidate ranking are now routinely automated. What has largely remained untouched, until now, is the interview: a…
