A Meteor Impact May Have Caused a Giant Landslide in the Grand Canyon

Researchers have long puzzled over the presence of driftwood and lake sediments in Stanton’s Cave in the eastern Grand Canyon, whose mouth sits 150 feet (45.7 meters) above the river. How could the material possibly have reached that height? According to Karl Karlstrom, a geologist from the University of New Mexico, it would have had to be carried by flood levels ten times bigger than any seen in the past several thousand years. An international team of researchers proposes a surprising chain o

Deflecting a Killer Asteroid Is More Complicated Than NASA Thought

In 2022, NASA rammed a spacecraft into an asteroid to see if it could alter its orbital period around its parent asteroid. The mission, dubbed the Double Asteroid Redirection Test (DART), aimed to determine whether humanity could theoretically save itself from a catastrophic asteroid impact. DART collided with Dimorphos, a small moonlet orbiting a larger asteroid called Didymos, on September 26, 2022. The results of the impact blew NASA’s expectations out of the water, shortening Dimorphos’s or

Evidence of a 12,800-year-old shallow airburst depression in Louisiana

Introduction Cosmic airbursts and impacts produce a wide range of surface effects, with high-altitude airbursts, such as the 1908 Tunguska event, primarily generating blast damage without forming craters [1]. In contrast, low-altitude “touch-down” airbursts may induce surface melting, spherule formation, shocked quartz, and shallow cratering [2]. Due to preservation challenges, few airburst signatures are documented in the geologic record, limiting our understanding of these events. Here, we rep

Kelly Benefits says 2024 data breach impacts 550,000 customers

Kelly & Associates Insurance Group (dba Kelly Benefits) is informing more than half a million people of a data breach that compromised their personal information. The Maryland-based health and life insurance agency has issued an update on a security incident it suffered last year between December 12-17, when unauthorized actors breached its IT systems and stole files. On April 9, 2025, the company stated that the incident impacted 32,234 individuals. The figure was revised multiple times until

Mortgage Rate Predictions: How Tariffs, War and the Fed Are Impacting Rates

Buyers should keep an eye on the possibility of rate cuts in the next few months. Tharon Green/CNET Mortgage market predictions have been clouded by economic uncertainty caused by the Trump administration's trade measures, deficit spending and geopolitical maneuvering. The big question hanging over the housing market is whether rates will rise due to tariff-induced inflation or fall due to a recession. Since early spring, average mortgage rates for 30-year fixed loans have been swinging betwee

Google services are experiencing a major disruption right now (Update: Mostly fixed)

C. Scott Brown / Android Authority TL;DR Google reports a disruption impacting Gmail and many other Workspace services. Problems were first noticed a little over an hour ago, just before 11a PT. Companies beyond Google also appear to be dealing with some connectivity issues of their own. Update, June 12, 2025 (03:34 PM ET): Literally just one minute after publishing our report, Google has updated its status dashboard to share that the problems are more or less fixed. The company says that e

NASA Makes Big Update to Asteroid Potentially on Collision Course With Earth in 2032

The potentially hazardous asteroid 2024 YR4 caused consternation over the last few weeks as its odds of hitting Earth in 2032 dramatically rose. Now, those odds have plummeted to near-zero, as astronomers’ calculations of the asteroid’s path have been updated to indicate that Earth is almost certainly not in the space rock’s plans. Almost. According to NASA’s Center for Near-Earth Object Studies (CNEOS), the asteroid’s current chance of hitting the planet in 2032 is 0.28%, or a 1-in-360 shot. T

The Odds of a City-Killing Asteroid Hitting Earth Keep Rising

An asteroid discovered late last year is continuing to stir public interest as its odds of striking planet Earth less than eight years from now continue to increase. Two weeks ago, when Ars first wrote about the asteroid, designated 2024 YR4, NASA’s Center for Near Earth Object Studies estimated a 1.9 percent chance of an impact with Earth in 2032. NASA’s most recent estimate has the likelihood of a strike increasing to 3.2 percent. Now that’s not particularly high, but it’s also not zero. Ars

Killer Asteroid Could Be Headed for Some of the World's Most Populous Cities

According to NASA's Jet Propulsion Lab, near-Earth asteroid 2024 YR4 now has a 3.1 percent chance of colliding with our planet on December 22, 2032. That makes it the highest-threat asteroid ever detected, as Euronews reports. As of late January, the probability was sitting at just 1.3 percent, which then rose to 2.1 percent last week before rising yet again. Worse yet, the space agency suggests the asteroid could hit densely populated areas of our planet — if it were to make an impact just un

Asteroid's Chances of Smacking Earth Increase. Here's What to Know

It's not great news, but don't panic: Astronomers spotted an asteroid that has a roughly 3.1% chance of impacting Earth on Dec. 22, 2032. Space agencies are monitoring the newly discovered asteroid and still learning more about its size and path, so don't mark your calendar for doomsday just yet. Although the odds of the asteroid hitting Earth have increased recently, that number is not set in stone. There's still a lot to learn about the space rock. Designated 2024 YR4, the asteroid was first
