It is the ultimate mystery of biology: How did life begin? A team of Harvard scientists has brought us closer to an answer by creating artificial cell-like chemical systems that simulate metabolism, reproduction, and evolution — the essential features of life. The results were published recently in the Proceedings of the National Academy of Sciences. “This is the first time, …

It’s hard to believe, but about 700m years ago it’s thought that our planet completely froze over with little to no liquid ocean or lakes exposed to the atmosphere, even in the tropics. But what tipped Earth’s climate into “Snowball Earth” state? A new study suggests a cold climate and massive volcanic eruptions set the scene. The Franklin eruptions – …

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights I was preparing for my early morning class back in January 2025 when I received a notice regarding an asteroid called 2024 YR4. It said the probability it could hit Earth was unusually high. As defending Earth from unexpected intruders …

A team of scientists has found the recently discovered “interstellar invader” comet 3I/ATLAS is teeming with water ice. This water could have been sealed in the comet for 7 billion years, which would make it older than the solar system itself. The team also found a mixture of organic molecules, silicates and carbon based minerals on the object, meaning 3I/ATLAS …

If you thought the Earth only had one moon, think again. Researchers have revealed that our planet may actually have an entire collection orbiting us at any given time. A new study has found that Earth has at least six ‘minimoons’ in orbit on a regular basis, with most of them being smaller pieces of the actual moon we see …

In a serendipitous turn of events, scientists have discovered that Japan’s Himawari-8 and Himawari-9 weather satellites, designed to monitor storms and climate patterns here on Earth, have also been quietly collecting valuable data on Venus for nearly a decade. Although meteorological satellites orbit Earth and scan the skies around it, their imaging range extends into space, allowing them to occasionally …

NASA’s TRACERS mission blasted off from California’s Vandenberg Space Force Base on Wednesday (July 23), after a 24-hour delay caused by airspace concerns. TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) is composed of twin satellites that will study how surges in the solar wind trigger magnetic reconnection in Earth‘s magnetosphere; such reconnection leads to charged particles being funneled down …

During the midday Friday prayer hours on March 28, 2025, a magnitude 7.7 earthquake struck central Myanmar along the Sagaing Fault. With an epicenter close to Mandalay, the country’s second-largest city, it was the most powerful earthquake to strike Myanmar in more than a century and the second deadliest in its modern history. The cause was a strike-slip fault, in …
