Far beyond Pluto, where sunlight is faint and temperatures remain extremely low, countless icy bodies drift through the outer reaches of the Solar System. These distant objects, known as trans-Neptunian objects, have long been viewed as frozen relics left over from the Solar System’s formation. Most are thought to be too small to hold onto…
Albert Einstein (Image: Wikipedia) Albert Einstein wrote, “Everything that is really great and inspiring is created by the individual who can labor in freedom.” The line is a straightforward claim about where genuinely original work actually comes from. Not from committees, not from rigid instruction, and not from people working under constant supervision, but from…
A 187-foot-tall dipterocarp tree For decades, scientists believed that the tallest trees faced one of nature’s toughest challenges: Getting water from their roots to leaves hundreds of feet above the ground. Now, a study of towering trees in Southeast Asia suggests some of the world’s tallest flowering plants have evolved specialised systems to overcome that…
Innovation often begins with solving problems that others consider impossible. For Dr Robert Sola Okojie, a Nigerian-born engineer and inventor, that pursuit has led to a career spanning more than two decades at Nasa and groundbreaking contributions to space technology. After 21 years at Nasa and securing 21 US patents, he was inducted into the…
Scientists have long relied on chemical traces locked inside ancient rocks to piece together the story of early life. Fossils from the deepest reaches of Earth’s history are rare, often fragmentary and difficult to interpret. Isotopes, by contrast, can survive for billions of years. Among the most informative are those linked to nitrogen, an element…
Most years, skywatchers have to wait patiently for different celestial events to arrive one at a time. An eclipse might dominate one month, while a meteor shower steals attention weeks later. This August, however, the calendar has produced a rare overlap. On 12 August 2026, a solar eclipse will unfold across parts of the Northern…
The Cambridge team behind the living algae-powered bio-battery: Lucia Giron, Dr Paolo Bombelli and Professor Chris Howe. Researchers at the University of Cambridge have developed a living bio-battery that generates electricity continuously using photosynthetic algae, offering a potential alternative to millions of disposable batteries used in everyday electronics. Unlike conventional batteries that gradually run out…
For decades, astronomers have searched for the birthplace of globular clusters, the dense spherical collections of stars that orbit galaxies today. These ancient systems are among the oldest visible structures in the Universe, yet their earliest history remains surprisingly difficult to reconstruct. Most theories have focused on crowded regions inside young galaxies, where gas was…
Australia’s renewable energy boom has reached a remarkable milestone. The country now generates so much electricity from rooftop solar panels that, during the middle of the day, wholesale power prices frequently fall to zero or even below zero. Instead of allowing surplus electricity to go to waste, eligible households in parts of Australia can now…
Football has a habit of borrowing the language of space. Players become stars, matches are described as astronomical, and careers are measured by how brightly they shine. Every so often, though, the comparison drifts into something more literal. More than a decade ago, astronomers studying one of the earliest known galaxies in the universe chose…
For most people, asteroids are distant objects that remain hidden behind telescope lenses and scientific instruments. That will briefly change in April 2029, when one of the best-known near-Earth asteroids is expected to become visible without specialist equipment across large parts of the world. The object, called Apophis, has attracted scientific attention for more than…
Quote of the day by John Locke (AI-generated image) You cannot know something you have never actually encountered in some form. That is the whole idea behind John Locke’s line, “No man’s knowledge here can go beyond his experience.” He wrote it in 1689, in An Essay Concerning Human Understanding, while arguing against the idea…
