On June 27, 2026, an IndiGo A320 became the first jet in India to land using Gagan, the country's own satellite navigation system. Here is how this technology guides aircraft to the runway without any ground-based radio equipment.

An IndiGo Airbus A320 made history by successfully landing in Udaipur using Gagan, India's indigenous satellite-based navigation system, marking a first for Indian aviation

India has two satellite navigation systems, Gagan and NavIC, and most people cannot tell them apart. Here is what each does, why they are not rivals, and why losing either would hurt the country.

The same song can make one person cry and leave another smiling, and science can explain why. From the physics of a note to dopamine, memories and the strange comfort of sad music, here is how sound becomes joy or sorrow in the brain.

This week, for Climate on My Plate, we discuss the onion on your plate, and why its price keeps swinging higher as the climate becomes less predictable.

A wet bulb temperature of 35 degrees Celsius has long been called the limit of human survival, the point where sweat can no longer cool the body. New research reveals the death threshold is far lower, and parts of South Asia are already dangerously close.

On July 8, about 99 per cent of the world's 8.2 billion people experience daylight or twilight at the same time. Earth's tilt and human geography combine for a fleeting global moment that lasts barely a minute.

A Bengaluru startup is testing India’s first full-flow staged combustion rocket engine, the same rare technology that only SpaceX's Raptor has ever flown to space.

A sitar and a piano can share a stage, but they can never truly agree on a single note. One is tuned to the pure ratios of physics, the other to a grid that deliberately breaks them, and here is the arithmetic behind that centuries-old divide.

France switched off three nuclear reactors and cut output at several more this week, after rivers meant to cool them grew too warm to use safely. India's coastal and inland reactors face a different risk.
