Earth may respond to the huge quantities of carbon dioxide (CO2) that humans are pumping into the atmosphere by “overcorrecting” the imbalance, which could result in the next ice age arriving on time instead of being delayed by tens of thousands of years, as had previously been predicted. This is due to a newfound “thermostat” … Read more
If you’ve ever wanted to get lost on Mars, now’s your chance: You can fly over a maze-like canyon on the Red Planet in a stunning new video from the European Space Agency (ESA). The animation, based on data from ESA’s Mars Express spacecraft, brings viewers on a “mesmerising flight over curving channels carved by … Read more
Most of us have likely experienced artificial intelligence (AI) voices through personal assistants like Siri or Alexa, with their flat intonation and mechanical delivery giving us the impression that we could easily distinguish between an AI-generated voice and a real person. But scientists now say the average listener can no longer tell the difference between … Read more
A Chinese company has released footage of a lifelike robot head that blinks, nods, and looks around in a convincing imitation of a real human face. The video, posted to YouTube, shows the robot head’s quizzical expression as it appears to take in its surroundings. The head, created by robotics company AheadForm, might find use … Read more
Scientists are considering the possibility of launching a nuclear weapon at an asteroid that could potentially hit the moon in 2032 — but they say more research is needed before taking this forward as an option. The investigation concerns asteroid 2024 YR4, which reached notoriety shortly after its discovery in December 2024 when scientists (working … Read more
Around 66 million years ago, the reign of the dinosaurs came to a fiery end. An asteroid about 7 miles (12 kilometers) wide, flying at 27,000 mph (43,000 km/h), slammed directly into Earth. The impact triggered a cascade of deadly events that led to the fifth mass extinction that eliminated dinosaurs, with the exception of … Read more
The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, it also influences plate tectonics which have continually reshaped the continents. But despite its importance, many of the most fundamental properties of the core are … Read more
Pluto is a bit of a loner. The dwarf planet is no longer considered a regular planet; it does not orbit on the same plane as the solar system’s eight planets; and its orbit is both highly elliptical and extremely tilted. In fact, its orbit is much more similar to that of its neighbors in … Read more
Who hasn’t looked into the sky and wondered if there’s life out there, somewhere, looking back at us? Is it possible there’s alien life closer to home — within the bounds of our solar system? The short answer is yes, there are several places researchers are looking for signs of life within our solar system, … Read more
A small municipality in southern Finland recently installed the world’s largest “sand battery” to supply the town’s heating. The new sand battery, designed by Polar Night Energy, is effectively a giant sandpit encased in a roughly 43 foot tall by 49 foot wide (13 by 15 meter) steel container. The sand is heated using closed-loop … Read more
