The Helix nebula, imaged here, lies 650 light-years away in the constellation Aquarius. Also known as NGC 7293, it is a typical example of planetary nebulae. (Image credit: Nasa) As children, many of us remember lying on terraces or open fields, trying to count stars. One, two, three and then losing track. Your parents would…

The waters of Lake Victoria have turned an unsettling green. And it seems, it’s not just a passing bloom this time. Local fishermen barely flinch anymore. What was once occasional now appears almost permanent. The world’s largest tropical lake is changing, and people who rely on it are feeling the effects every day. Millions in…

Source: University of Florida Gravity seems constant but it turns out, Earth is weirder than that. Gravity actually wobbles a bit across the planet. And the weakest spot isn’t the oceans or the mountains but right under Antarctica. Scientists now say this part of the frozen continent sits above Earth’s strongest “gravity hole.” And it…

What is the difference between asteroids, comets, and meteors Space around the Sun contains far more than planets. Scattered through it are smaller bodies made of rock, metal, ice and dust. These objects move on their own paths, sometimes quietly beyond Jupiter, sometimes crossing close to Earth. The terms ‘asteroid’, ‘comet’ and ‘meteor’ are often…

Scientists warn! Gulf Stream collapse could trigger severe global disruption Scientists are again examining the strength of the Atlantic Meridional Overturning Circulation, the vast ocean system that moves warm water northwards through the Atlantic. The current, often linked in public discussion to the Gulf Stream, helps shape weather patterns across Europe, North America and parts…

4.4 billion-year-old mineral found in Australia reveals new clues about Earth’s formation (AI-generated) Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape. These minerals, known as zircons, were recovered from ancient rocks in the Jack Hills region and are dated to be more than four…

Planets are often described as ancient, unchanging worlds. Planets are born out of chaos, shaped by violent collisions and swirling dust. They grow, they evolve, and in their own way, they age. Some endure for staggering lengths of time. Others meet surprisingly dramatic ends. So what is the typical lifespan of a planet? The answer…

Isaac Newton (Image source: Wikipedia) Isaac Newton was an English polymath who worked in many areas, such as math, physics, astronomy, alchemy, theology, writing, and inventing. His work changed the way people thought about the universe and set the stage for classical physics. Newton looked at nature very closely and tried to use math and…

Animal behaviour during solar eclipse Solar eclipses are among nature’s most unusual and dramatic events. The Moon casts a shadow on the Earth that changes the light and temperature in some places for a short time when it moves between the Earth and the Sun. While scientists focus much attention on what solar eclipses reveal…

Solar Eclipse February 17 The annular or “Ring of Fire” solar eclipse will happen today, February 17, 2026. This celestial event will get a lot of attention around the world, but it won’t be visible from India. Because solar eclipses are talked about a lot and people often think they can see them from anywhere,…
