NASA scientists have confirmed that a mysterious object shooting toward us through the solar system is an “interstellar object” — only the third of its kind ever seen. Experts have also given the cosmic interloper an official name, and revealed new information about its origins and trajectory. News of the extrasolar entity, initially dubbed A11pl3Z, … Read more
A U.K. start-up has shocked the space exploration community after unveiling plans to use a novel nuclear fusion propulsion system to power an orbital fleet of reusable “alien-like” rockets, known as Sunbirds, which the company says could revolutionize how we explore the solar system — and beyond. The technology behind this ambitious project will begin … Read more
A quartet of Earth-like worlds, each about 20% to 30% the size of our planet, circle one of our closest stellar neighbors, a new study reveals. The rocky alien worlds are close enough that future generations of humans may be able to visit them with futuristic rocket propulsion technology. However, it is unlikely that we … Read more
Punishing artificial intelligence for deceptive or harmful actions doesn’t stop it from misbehaving; it just makes it hide its deviousness, a new study by ChatGPT creator OpenAI has revealed. Since arriving in public in late 2022, artificial intelligence (AI) large language models (LLMs) have repeatedly revealed their deceptive and outright sinister capabilities. These include actions … Read more
Without a doubt, since its launch, the James Webb Space Telescope (JWST) has revolutionized our view of the early universe, but its new findings could put astronomers in a spin. In fact, it could tell us something profound about the birth of the universe by possibly hinting that everything we see around us is sealed … Read more
Scientists have devised a way to store and read data from individual atoms embedded in tiny crystals only a few millimeters in size (where 1 mm is 0.04 inches). If scaled up, it could one day lead to ultra-high density storage systems capable of holding petabytes of data on a single disc — where 1 … Read more
For the first time, scientists have observed water molecules splitting in real time to form hydrogen and oxygen. And right before they split, the molecules did something completely unexpected: They flipped 180 degrees. This micro acrobatic stunt takes energy, which offers a crucial explanation for why splitting water takes more energy than theoretical calculations suggested. … Read more
The rise of artificial general intelligence (AGI) — an artificial intelligence (AI) system with superhuman intelligence that can perform well at various tasks — is a matter of when, not if, according to a new analysis of thousands of expert opinions. The updated analysis, conducted Feb. 18 by Cem Dilmegani, principal analyst at AIMultiple Research, … Read more
A knight in “shining armor” wielding a sword or lance is an iconic medieval image, but more advanced weapons also appeared in the Middle Ages — including guns that fired bullets. This leads to an interesting question: Could the metal suits worn by knights and other warriors block a bullet? Live Science contacted experts to … Read more
Modern humans now permanently live on every continent except Antarctica, but it wasn’t always this way. After our species, Homo sapiens, emerged in Africa at least 300,000 years ago, some eventually ventured out, trekking and voyaging across the world. So when did the first modern humans reach each of the seven continents? The accepted ideas … Read more
