Meteorite That Crashed Into A Home In The US Is Older Than Earth, Study Finds
In a Friday news release, University of Georgia planetary geologist Scott Harris announced his findings after studying 23 grams of meteorite fragments, which pierced a man's home and dented the floor in McDonough, Henry County. Mr Harris examined the fragments under microscopes and determined they originated from a meteorite formed 4.56 billion years ago, predating Earth's estimated age of 4.54 billion years.
"This particular meteor that entered the atmosphere has a long history before it made it to the ground of McDonough, and in order to totally understand that, we actually have to examine what the rock is and determine what group of asteroids it belongs to," Mr Harris said in the news release.
"This is something that used to be expected once every few decades and not multiple times within 20 years. Modern technology, in addition to an attentive public, is going to help us recover more and more meteorites," Mr Harris added.
The geologist aims to publish his research on asteroid composition and speed, which could enhance our understanding of potential asteroid threats.
Meamwhile, the homeowner reported still finding traces of space dust around his property from the impact. Named the McDonough meteorite, the object is the 27th meteorite recovered in Georgia.
In June, a bright fireball lit up the southeastern US sky in broad daylight, prompting reports to the American Meteor Society. NASA confirmed the meteor's entry into Earth's atmosphere coincided with the Bootids meteor shower, a minor celestial event occurring late June. Around the same time, a resident of Henry County, Georgia, reported a rock crashing through his ceiling, later identified as the McDonough Meteorite. The meteorite pierced the roof, ceiling, and flooring of the home, causing significant damage.

Fuel Fill-Ups in Space? Musk and Bezos Are Working on It
Elon Musk and Jeff Bezos are trying to figure out how to pump gas in space. The billionaire space rivals are working on ambitious missions to the moon or Mars, and a crucial design element for each venture is using spacecraft that take on additional fuel while orbiting Earth. Vehicles that could grab propellants in orbit would be less weighed down at liftoff, letting planners design missions to travel farther from Earth with more cargo, scientific gear or crew members, advocates say. Having depots or in-orbit refueling that give spacecraft something like a truck stop to pull into may sound like science fiction. It is also a concept that engineers have been working on for years. One of the biggest challenges to making it a reality: moving and storing massive amounts of supercold propellants that are prone to boil off in the void of space. Both SpaceX and Blue Origin have much to prove. Some space-industry officials are skeptical that either will have moon landers that depend on orbital fueling ready to meet National Aeronautics and Space Administration timelines. The agency has worked closely with contractors to understand the challenges of in-space refueling, a NASA spokesman says. SpaceX conducted a fuel-transfer demonstration inside a Starship spacecraft during a 2024 test flight and next year is aiming to move propellants between two vehicles. That test has been delayed as the company has faced setbacks with the massive rocket, including an explosion during a ground test in Texas in June. Blue Origin is developing a transporter vehicle that would take on propellant near Earth. Then, it would fly to a lunar orbit, where the transporter would prepare a lander that would take astronauts arriving on a different ship down to the surface of the moon. That mission depends on the company's New Glenn rocket, which the company launched for the first time in January. Engineers have long built rockets and spacecraft to take on all the fuel they need while still on the ground. Those designs have proven their value. They also have their limitations. Take NASA's Apollo missions to the moon. Saturn V, the rocket that sent agency astronauts there, weighed 6.5 million pounds at liftoff, and around 5.5 million of those pounds were fuel. Combined with reusable rockets, fueling in space could make deep-space flights cheaper over time and ease mission logistics, supporters say. 'It has got to be done,' says Dallas Bienhoff, who formerly studied setting up a low-Earth-orbit propellant depot for Boeing and now works for Pasadena, Calif.-based robotic-mining company OffWorld. 'Otherwise, we're going to be limited with what we can achieve in space.' Musk put it this way during a conference talk in 2017. Starship, which then went by a different name, was expected to loft a spacecraft carrying a large amount of mass to low-Earth orbit. The ship wouldn't be able to travel farther without more fuel, he said. 'If you send up tankers, and refill in orbit, you can refill the tanks all the way to the top,' Musk said then. That would allow the ship to continue out to Mars, he added. From Apollo to the present Orbital refueling isn't a new idea. In the early 1960s, NASA officials considered such operations as they tried to figure out how to land astronauts on the lunar surface before the Soviets. The idea didn't go forward then, but it didn't go away. A range of in-space fueling experiments or operations have been conducted over the years, including by Russia. In 2007, the Pentagon's Defense Advanced Research Projects Agency and partners conducted more than a dozen fuel transfers between two satellites. But no U.S. company has put in-space propellant transfers at the center of their deep-space plans as SpaceX and Blue Origin have. Part of the reason is making it all work is difficult. Spacecraft will need to rendezvous in orbit, connect with each other and flow large amounts of propellants from one vehicle to another. The nature of the propellants SpaceX and Blue Origin have proposed using makes transferring them especially tricky. The fuels are chilled to supercold levels to keep them liquid, and have a tendency to boil off. 'It wouldn't be easy to do on Earth. But now you have to do it in space, pumping it from one big refrigerator to another,' says Thomas Cooley, formerly chief scientist for a space-vehicles group at the Air Force Research Laboratory who now has a space-consulting business. Dave Limp, chief executive at Blue Origin, said in a social-media post in July the company had made major progress maturing technologies that aim to prevent propellants from boiling off in space. Fuels also behave in odd ways in space. When you pump gasoline into your car's tank, the gas flows in a predictable manner but that isn't necessarily the case in orbit. There, companies will contend with what William Notardonato, chief executive of Eta Space, calls 'liquid-acquisition issues.' 'You don't know where your liquid is stored. The propellant might be up at the top of the tank. And it brings up the question, what is the top in microgravity?' says Notardonato, whose Rockledge, Fla.-based company is developing an in-space propellant depot and working on a mission where it will track how a supercold propellant behaves in a satellite tank using a camera. Launching, time and again Another unknown for in-orbit refueling: the number of launches it will take SpaceX and Blue Origin to fuel up vehicles for deep-space missions. SpaceX has shown launches can be conducted much more frequently than in the past, but rockets are still a long way from flying as easily as commercial jets. Meanwhile, Starship, the company's vehicle that will use orbital fueling, remains in an experimental phase and Blue Origin is still ramping up New Glenn. During a presentation earlier this year, a Blue Origin executive didn't specify how many refueling flights the company may need for a NASA mission that has it transporting astronauts from lunar orbit to the surface of the moon. For its NASA astronaut moon missions, SpaceX has been planning to conduct multiple launches of a tanker variant of its Starship spacecraft to fuel up a Starship depot in low-Earth orbit, according to NASA officials. Then the company would send a moon-lander Starship to the depot to take on fuel. After that, the lander would fly out to the moon. An executive at SpaceX early last year estimated a moon mission for NASA could take around 10 flights, while a different leader at the company last fall predicted around 16. Some current and former space-industry officials say the number of launches needed may be higher. One former NASA leader during a congressional hearing in February said as many as 20 could be required. A technical paper that has circulated among some industry officials and was viewed by The Wall Street Journal suggests it may take up to 40. Musk, during a recent presentation about SpaceX's plans for Mars, didn't discuss the number of flights that would be needed to send a Starship to the red planet. Staff at the company have talked about trying to send a basic, uncrewed ship out there next year with as few as three refueling flights, the Journal has reported. In a recent post on his social-media site X, Musk said a Starship flight to Mars in 2026 would be tough, giving it just a slight chance of happening.

It's not the melting ice that's raising the seas; it's Earth's drying continents, study warns
Earth's continents are drying, causing sea levels to rise faster than melting ice. Satellite data shows dry areas expanding rapidly. Groundwater depletion, mainly for agriculture, is a major cause. Regions like Canada and Russia face significant water loss. This threatens freshwater resources and accelerates coastal flooding. Protecting groundwater is now a global priority. Tired of too many ads? Remove Ads Satellite data tracks a drying planet Tired of too many ads? Remove Ads Where the water is going The reason: Human pressure on groundwater Tired of too many ads? Remove Ads The warning Everyday sources of life, the rivers we get our water from, the lakes we fish in, and the groundwater that sustains farms, are quietly disappearing. But the consequences stretch far beyond parched fields and empty reservoirs. A new study shows that this drying of Earth's continents, rather than the melting of polar ice sheets, has now become the dominant driver of global sea level rise The findings, published in Science Advances by researchers led by Hrishikesh Chandanpurkar of FLAME University, India, show that vast amounts of terrestrial water are draining into the oceans, tilting the global water balance in unprecedented two decades of satellite measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) and its follow-on mission, the team reconstructed how Earth's terrestrial water storage has shifted since results are stark: continental areas experiencing drying are expanding by an area nearly twice the size of California every year. In contrast, wet areas are not growing fast enough to compensate.'Dry areas are drying faster than wet areas are wetting,' the researchers write, warning that the shift is both accelerating and analysis found that much of the missing water has ended up in the oceans, where it is now adding more to sea level rise than the planet's ice were especially pronounced in high-latitude regions like Canada and Russia, where melting permafrost and ice are releasing stored non-glacial regions, up to 68 percent of the decline is tied directly to human groundwater depletion Across many continents, agriculture remains the biggest driver of groundwater loss. California's Central Valley, which supplies 70 percent of the world's almonds, and cotton-growing regions around the former Aral Sea in Central Asia are among the worst rainfall patterns becoming increasingly erratic due to fossil fuel-driven climate change, communities are drawing heavily on aquifers. But these deep water reserves are not replenishing nearly as quickly as they are drained.'At present, overpumping groundwater is the largest contributor to terrestrial water storage decline,' the study notes, amplifying the risks from heatwaves, droughts, and net result is a 'double jeopardy': continents are losing the freshwater resources that billions depend on, while oceans rise faster and swallow coastlines. Three out of every four people already live in countries where freshwater loss is England, for instance, 2025 was declared the driest spring in 132 years, with water reservoirs running so low that centuries-old structures, like an ancient packhorse bridge, authors stress that safeguarding groundwater must become a global priority. Even if slowing climate change remains politically fraught, policies to conserve and sustainably manage groundwater can be enacted now.'Protecting the world's groundwater supply is paramount in a warming world and on continents that we now know are drying,' they conclude.

Worried about microplastics in your drinking water? Here's how you can easily remove it
Plastics that enter our bodies in the form of small fragments are a serious concern, as they enter our bodies in small quantities in solid or liquid form through food and drink. Chinese scientists found an easy and effective means of removing them from water. The team of scientists ran tests in 2024 on both soft water and hard tap water, which is considered richer in minerals. They added in nanoplastics and microplastics and then boiled the liquid, and filtered out any precipitates. "Tap water nano/microplastics (NMPs) escaping from centralized water treatment systems are of increasing global concern, because they pose potential health risks to humans via water consumption," the researchers from Guangzhou Medical University and Jinan University write in their published paper, as quoted by online portal Science Alert. Up to 90% of the NMPs were removed through boiling and filtering in some cases, but the success rate depended on the water type. The major benefit lies in the fact that the majority of people can do it with what they already have in their kitchen. "This simple boiling water strategy can 'decontaminate' NMPs from household tap water and has the potential for harmlessly alleviating human intake of NMPs through water consumption," biomedical engineer Zimin Yu from Guangzhou Medical University and colleagues wrote, Science Alert reported. Higher amounts of NMPs were removed from hard tap water samples, which tend to form limescale (calcium carbonate) buildup when heated. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo The chalky substance, which is quite often found inside kitchen kettles, forms on the plastic's surface due to temperature changes that force the calcium carbonate out of solution, effectively trapping the plastic fragments in a crust. "Our results showed that nanoplastic precipitation efficiency increased with increasing water hardness upon boiling," the team wrote. As far as soft water is concerned, where less calcium carbonate is dissolved, approximately a quarter of the NMPs were captured from the water. According to the researchers, any small pieces of lime-covered plastic can then be removed using a simple filter, like the stainless steel mesh used for straining tea. Live Events
