On 22 February 1498, a well-weathered mid-40s Christopher Columbus ordained in writing that his estate in the Italian port city of Genoa would be maintained for his family “because from it I came and in it I was born”. Though most historians regard the document to be a cut-and-dried record of the famed explorer’s birthplace,

Around a neighboring star just 635 light-years away, astronomers have found even more evidence of a moon absolutely livid with volcanoes. There is a giant cloud of sodium consistent with volcanic activity, orbiting an exoplanet named WASP-49b, orbiting in turn a yellow dwarf star named WASP-49. And how do we know that the sodium is
The Sunshine State is bracing for more severe weather in the wake of Hurricane Helene. Hurricane Milton rapidly intensified to a Category 5 storm on Monday, leading Florida Gov. Ron DeSantis to declare a state of emergency for 51 counties along Florida’s western shores. Several counties, including Charlotte, Hillsborough, and Manatee, have mandatory evacuation orders,
The rapid development of artificial intelligence (AI) has brought both benefits and risk. One concerning trend is the misuse of voice cloning. In seconds, scammers can clone a voice and trick people into thinking a friend or a family member urgently needs money. News outlets, including CNN, warn these types of scams have the potential
Updated 9:45 a.m. Eastern with Starship landing. MILAN — SpaceX launched its fifth Starship vehicle Oct. 13, successfully making an unprecedented “catch” of its Super Heavy booster back at the launch site. The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at Boca Chica, Texas, at 8:25 a.m. Eastern on a mission called
Our gleaming blue marble of a planet is a treasure that shimmers and sparkles in the darkness of space. Most of humanity will never get a first-person view of this magnificent sight. But the rare few that experience the wonder of extraterrestrial travel have documented their journeys in detail, giving us a breathtaking, beautiful glimpse
You don’t have to look far to see what climate change is doing to the planet. The word “unprecedented” is everywhere this year. We are seeing unprecedented rapidly intensifying tropical storms such as Hurricane Helene in the eastern United States and Super Typhoon Yagi in Vietnam. Unprecedented fires in Canada have destroyed towns. Unprecedented drought
The 2024 Nobel Prize in chemistry recognized Demis Hassabis, John Jumper and David Baker for using machine learning to tackle one of biology’s biggest challenges: predicting the 3D shape of proteins and designing them from scratch. This year’s award stood out because it honored research that originated at a tech company: DeepMind, an AI research
WASHINGTON — The Federal Aviation Administration will allow SpaceX to resume Falcon 9 flights after an upper stage anomaly nearly two weeks ago as the company awaits approval for its next Starship launch. In a statement late Oct. 11, the FAA said it cleared launches of the Falcon 9 that, with one exception, had been
Near-Earth asteroid Bennu has taught us a lot about the nature of asteroids and the history of our planet, and it’s not done yet. A new study of Bennu tracking data gives us fresh clues on a potential fifth fundamental force in the Universe. If in fact it does exist, the fifth force of nature
As Hurricane Milton roared ashore near Sarasota, Florida, tens of thousands of people were in evacuation shelters. Hundreds of thousands more had fled coastal regions ahead of the storm, crowding highways headed north and south as their counties issued evacuation orders. But not everyone left, despite dire warnings about a hurricane that had been one
Imagine three people huddled in a circle so when one speaks, only one other hears. Scientists have created a device that works like that, ensuring sound waves ripple in one direction only. The device, developed by scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne, is made up of a disk-shaped cavity
WASHINGTON — The United Arab Emirates will launch a mission to visit several asteroids later this decade on a Japanese H3 rocket. The UAE Space Agency (UAESA) announced Oct. 10 it selected Mitsubishi Heavy Industries to launch its Emirates Mission to the Asteroid Belt (EMA) on an H3 rocket in the first quarter of 2028.
A massive ball of plasma and accompanying magnetic field ejected from the Sun is expected to strike Earth on Thursday morning, potentially triggering auroras as far south as Alabama, according to US forecasters. It comes as the Sun approaches – or is possibly at – the peak of its 11-year cycle, when activity is heightened.
After an unseasonably quiet August, the Atlantic hurricane season is ramping up. Hurricane Milton, now a Category 4, is forecast to land over Florida Wednesday night as the state is still cleaning up the damage from Hurricane Helene, which hit less than two weeks prior. These back-to-back storms aren’t the end of what we may
If your jaw dropped as you watched the latest AI-generated video, your bank balance was saved from criminals by a fraud detection system, or your day was made a little easier because you were able to dictate a text message on the run, you have many scientists, mathematicians and engineers to thank. But two names
WASHINGTON — A startup led by a founder of a financial services company is taking a new approach to space-based solar power intended to be more scalable and affordable than previous concepts. Aetherflux announced Oct. 9 plans to develop and ultimately deploy a constellation of satellites in low Earth orbit that will collect solar power
The inner workings of our brain’s ‘sewage system’ are finally coming to light after years of speculation. Deep within the crevices of five human brains, scientists have, for the very first time, imaged the dynamic intricacies of a underlying plumbing network – previously seen in mice and only hypothesized in our own species. The findings
There are worlds out there far stranger than those we might dream up – and a real oddball we’ve been studying in puzzlement for years just got even odder. Its name is WASP-107b, an exoplanet orbiting a star just 200 light-years away, and it caught humanity’s attention for its unusual composition. WASP-107b is 96 percent
Hurricane Milton went from barely hurricane strength to a dangerous Category 5 storm in less than 24 hours as it headed across the Gulf of Mexico toward Florida. As its wind speed increased, Milton became one of the most rapidly intensifying storms on record. And with 180 mph sustained winds on Oct. 7, 2024, and
SAN FRANCISCO – As a group, NASA’s low-cost science missions have improved significantly. “There were lessons learned over the years that helped,” said Charles Norton, NASA Jet Propulsion Laboratory deputy chief technologist. “In the beginning there were a lot of failures. The community bootstrapped itself to become successful.” In fact, low-cost, risk-tolerant Class-D small satellite
A study on the brains of mice has identified a neurological relay race unfolding at meal time, dividing activity into four separate phases that ensure the animals don’t eat too much or too little. While the research doesn’t identify the exact physiological cues that define each act, the findings hint at a complex interplay of
Small primordial black holes (PBHs) are one of the hot topics in astronomy and cosmology today. These hypothetical black holes are believed to have formed soon after the Big Bang, resulting from pockets of subatomic matter so dense that they underwent gravitational collapse. At present, PBHs are considered a candidate for dark matter, a possible
COCOA BEACH, Fla. — The Federal Aviation Administration has granted approval for the Falcon 9 launch of the European Space Agency’s Hera asteroid mission, but is keeping the vehicle grounded for now for other missions. In an Oct. 6 statement, the FAA stated it authorized a return to flight for the Falcon 9 solely for
A dwarf planet thought to have some ice mixed in with its dirty surface may have a lot more cool than we ever expected. Ceres – the largest body in the asteroid belt between Mars and Jupiter – could have a crust consisting of more than 90 percent water ice. If this is the case,
WASHINGTON — The first satellites of a Chinese broadband constellation are significantly brighter than those of Western systems, posing a new challenge for astronomers. In a paper posted on the arXiv preprint server Sept. 30, a group of observational astronomers reported on observations of a set of 18 Qianfan, or “Thousand Sails,” satellites launched in
The way the human brain remembers certain individuals is closely linked to how we talk about them. Neuroscientists have now shown that pronouns like ‘he’, ‘she’, or ‘they’ can activate the same neuron in the brain as a person’s specific name. Take these two sentences as an example: “Shrek and Courtney Love walked into a
There’s nothing else like Earth and its Moon in the entire Solar System. Other planets either have multiple moons, or none at all, but the mass ratio of our world and its hefty satellite is quite unique. The question of our unusual moon’s origin, therefore, is one of planetary evolution, figuring out the pathways for
Updated 6 p.m. Eastern with additional details on nozzle anomaly. WASHINGTON — United Launch Alliance’s second Vulcan Centaur lifted off Oct. 4 on a test flight needed to certify the vehicle for carrying national security payloads, but may have suffered a problem with one of its solid rocket boosters. The Vulcan Centaur lifted off at
Supermassive black holes are some of the most impressive (and scary) objects in the universe – with masses around one billion times more than that of the Sun. And we know the’ve been around for a long time. In fact, astronomers have detected the extremely luminous compact sources that are located at the centres of
