NASA Curiosity Rover Shocking Discovery: How the Rock Formed on Mars?
According to NASA, coral-shaped rocks like this formed billions of years ago when Mars still had liquid water. This water contained dissolved minerals that moved through small cracks in existing rocks. Over time, minerals were deposited and created solid veins within the rock structure.
Live Events
These mineral veins formed branching patterns. After millions of years, sand-laden winds eroded surrounding material, exposing the branch-like formations we see today.

Meteorite that hit home in US this summer is older than earth, researchers say
A meteorite that crashed into a home in Atlanta, Georgia, is older than our planet Earth, according to a scientist who examined a fragment of the space rock. '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,' said Scott Harris, a researcher in the UGA Franklin College of Arts and Sciences' department of geology. Harris examined 23 of the 50 grams of meteorite fragments recovered from a piece the size of a cherry tomato that struck a man's roof like a bullet and left a dent in the floor of the home outside Atlanta. 'It belongs to a group of asteroids in the main asteroid belt between Mars and Jupiter that we now think we can tie to a breakup of a much larger asteroid about 470 million years ago,' Harris says. 'But in that breakup, some pieces get into Earth-crossing orbits, and if given long enough, their orbit around the sun and Earth's orbit around the sun end up being at the same place, at the same moment in time.' The geologist used optical and electron microscopy to determine that the rock was a chondrite, a type of meteorite that originated in the early solar system and is rich in carbon, water, and clay materials. In fact, according to NASA, chondrites are the most abundant type of stony meteorite. Harris said that scientists at the University of Georgia, along with colleagues from Arizona State University, plan to submit their findings to the Nomenclature Committee of the Meteoritical Society. They have proposed naming the space rock the McDonough Meteorite, reflecting the name of the Georgia city where it struck the Earth. The University of Georgia said the meteorite studied by Hariss and the team , was the the 27th meteorite recovered in the history of the state, and was among the sixth witnessed fall. 'This is something that used to be expected once every few decades and not multiple times within 20 years,' Harris said. 'Modern technology in addition to an attentive public is going to help us recover more and more meteorites.' Over the years, scientists have sought to understand the role of meteorites in the formation of the solar system. Earth formed roughly 4.5 billion years ago. In its infancy, it was bombarded by meteorites, comets, and other material from space. In June, the American Meteor Society received reports of a fireball that streaked across the southeastern U.S. sky in broad daylight. NASA confirmed that the meteor entered Earth's atmosphere during the Bootids meteor shower, a relatively minor celestial event occurring in the last week of June. Around the same time, a resident of Henry County, Georgia, reported that a rock, now identified as the McDonough Meteorite, crashed through their ceiling, according to the National Weather Service in Peachtree City. The object broke through the roof and ceiling before cracking the flooring inside the home. 'I suspect that he heard three simultaneous things. One was the collision with his roof, one was a tiny cone of a sonic boom and a third was it impacting the floor all in the same moment,' Harris said. 'There was enough energy when it hit the floor that it pulverized part of the material down to literal dust fragments.'

Karl Kruszelnicki: The Australian scientist who unraveled the Bermuda Triangle myth
Karl Kruszelnicki , a prominent Australian scientist, has gained widespread attention for demystifying one of the most enduring and sensational legends in modern maritime folklore - the Bermuda Triangle . Known popularly as the "Devil's Triangle," this patch of the Atlantic Ocean, roughly bounded by Florida, Bermuda, and the Greater Antilles, has long been associated with the mysterious disappearance of ships and aircraft, fueling endless theories involving sea monsters, aliens , and even the lost city of Atlantis. Yet Kruszelnicki firmly dispels these myths, offering a grounded, science-based explanation that aligns with expert agencies and decades of statistical data.

He holds degrees in mathematics, physics, biomedical engineering, medicine, and surgery, and he has also studied astrophysics, computer science, and philosophy. He began his career working as a physicist designing testing machines for steel used in major infrastructure projects but resigned after ethical conflicts. Over the years, he has worked in diverse roles including car mechanic, roadie for famous musicians, filmmaker, biomedical engineer, taxi driver, and medical doctor, notably serving as a pediatrician before transitioning mostly into science communication. Live Events He is well-known for his engaging and accessible science commentary on Australian radio, television, and podcasts, particularly on ABC's Triple J, where his weekly science talk show draws hundreds of thousands of listeners. Dr Karl has authored 48 books, covering a wide range of scientific topics in a fun and understandable manner. Since around 2017, Kruszelnicki has consistently articulated his perspective: the incidents attributed to the Bermuda Triangle are not anomalous but simply the result of probabilities, navigational challenges, natural hazards, and human error. He states emphatically that 'the number of ships and planes that go missing in the Bermuda Triangle is the same as anywhere in the world on a percentage basis,' a claim backed by organizations like the U.S. National Oceanic and Atmospheric Administration (NOAA) and the renowned insurance market Lloyd's of London, whose risk assessments have debunked the idea of supernatural causation since the 1970s. Kruszelnicki's argument is informed by the fact that the Bermuda Triangle is one of the world's busiest shipping and flight corridors. The heavy volume of traffic combined with the region's navigational hazards helps to explain the proportionate number of accidents. The waters around Bermuda are dotted with reefs and shallow areas where more than 300 shipwrecks have been documented, many caused by collisions with these underwater features. The area's location near the Gulf Stream—a powerful and sometimes violently unstable current—also subjects vessels and aircraft to sudden and extreme weather changes, including tropical storms and hurricanes, especially during the June-November hurricane season. Such environmental factors significantly increase the risks of accidents. Kruszelnicki also highlights the errors of human operators as a critical factor. A famous example is Flight 19 , a group of five U.S. Navy TBM Avenger torpedo bombers that vanished during a 1945 training mission. Kruszelnicki points out that the flight was led by a navigator who had previously demonstrated poor navigational skills and did not follow established protocols once lost at sea. As a result, the group flew further into the open ocean until running out of fuel and disappearing. This incident, often cited as emblematic of the Bermuda Triangle's mystery, in fact underscores how human fallibility and natural conditions combine to produce tragedy. Throughout numerous public appearances and media engagements—most recently in 2023—Kruszelnicki has maintained that no mysterious forces or conspiracies are necessary to explain the disappearances. The U.S. Navy and Coast Guard also support this view, emphasizing that terrestrial factors and human mistakes far outstrip any paranormal theories. He remarks that while supernatural ideas are culturally appealing and have fueled books, movies, and TV shows, the reality is far more mundane but no less tragic. In sum, Karl Kruszelnicki stands as a leading figure in bringing modern science to bear on a legendary maritime myth. Through careful analysis and engagement with expert data, he has helped to reframe the Bermuda Triangle not as a zone of supernatural peril, but as a region where ordinary risks multiply in a complex natural and human environment.

NASA plans to build a nuclear reactor on the Moon – a space lawyer explains why, and what the law has to say
Mississippi, Aug 11 (The Conversation) The first space race was about flags and footprints. Now, decades later, landing on the Moon is old news. The new race is to build there, and doing so hinges on power. In April 2025, China reportedly unveiled plans to build a nuclear power plant on the Moon by 2035. This plant would support its planned international lunar research station. The United States countered in August, when acting NASA Administrator Sean Duffy reportedly suggested a US reactor would be operational on the Moon by 2030. While it might feel like a sudden sprint, this isn't exactly breaking news. NASA and the Department of Energy have spent years quietly developing small nuclear power systems to power lunar bases, mining operations and long-term habitats. As a space lawyer focused on long-term human advancement into space, I see this not as an arms race but as a strategic infrastructure race. And in this case, infrastructure is influence. A lunar nuclear reactor may sound dramatic, but its neither illegal nor unprecedented. If deployed responsibly, it could allow countries to peacefully explore the Moon, fuel their economic growth and test out technologies for deeper space missions. But building a reactor also raises critical questions about access and power. The legal framework already exists Nuclear power in space isn't a new idea. Since the 1960s, the US and the Soviet Union have relied on radioisotope generators that use small amounts of radioactive elements – a type of nuclear fuel – to power satellites, Mars rovers and the Voyager probes. The United Nations' 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space, a nonbinding resolution, recognises that nuclear energy may be essential for missions where solar power is insufficient. This resolution sets guidelines for safety, transparency and international consultation. Nothing in international law prohibits the peaceful use of nuclear power on the Moon. But what matters is how countries deploy it. And the first country to succeed could shape the norms for expectations, behaviours and legal interpretations related to lunar presence and influence. The 1967 Outer Space Treaty, ratified by all major spacefaring nations including the US, China and Russia, governs space activity. Its Article IX requires that states act with 'due regard to the corresponding interests of all other States Parties.' That statement means if one country places a nuclear reactor on the Moon, others must navigate around it, legally and physically. In effect, it draws a line on the lunar map. If the reactor anchors a larger, long-term facility, it could quietly shape what countries do and how their moves are interpreted legally, on the Moon and beyond. Other articles in the Outer Space Treaty set similar boundaries on behaviour, even as they encourage cooperation. They affirm that all countries have the right to freely explore and access the Moon and other celestial bodies, but they explicitly prohibit territorial claims or assertions of sovereignty. At the same time, the treaty acknowledges that countries may establish installations such as bases — and with that, gain the power to limit access. While visits by other countries are encouraged as a transparency measure, they must be preceded by prior consultations. Effectively, this grants operators a degree of control over who can enter and when. Building infrastructure is not staking a territorial claim. No one can own the Moon, but one country setting up a reactor could shape where and how others operate – functionally, if not legally. Infrastructure is influence Building a nuclear reactor establishes a country's presence in a given area. This idea is especially important for resource-rich areas such as the lunar south pole, where ice found in perpetually shadowed craters could fuel rockets and sustain lunar bases. These sought-after regions are scientifically vital and geopolitically sensitive, as multiple countries want to build bases or conduct research there. Building infrastructure in these areas would cement a country's ability to access the resources there and potentially exclude others from doing the same. Critics may worry about radiation risks. Even if designed for peaceful use and contained properly, reactors introduce new environmental and operational hazards, particularly in a dangerous setting such as space. But the UN guidelines do outline rigorous safety protocols, and following them could potentially mitigate these concerns. Why nuclear? Because solar has limits The Moon has little atmosphere and experiences 14-day stretches of darkness. In some shadowed craters, where ice is likely to be found, sunlight never reaches the surface at all. These issues make solar energy unreliable, if not impossible, in some of the most critical regions. A small lunar reactor could operate continuously for a decade or more, powering habitats, rovers, 3D printers and life-support systems. Nuclear power could be the linchpin for long-term human activity. And it's not just about the Moon – developing this capability is essential for missions to Mars, where solar power is even more constrained. A call for governance, not alarm The United States has an opportunity to lead not just in technology but in governance. If it commits to sharing its plans publicly, following Article IX of the Outer Space Treaty and reaffirming a commitment to peaceful use and international participation, it will encourage other countries to do the same. The future of the Moon won't be determined by who plants the most flags. It will be determined by who builds what, and how. Nuclear power may be essential for that future. Building transparently and in line with international guidelines would allow countries to more safely realise that future. A reactor on the Moon isn't a territorial claim or a declaration of war. But it is infrastructure. And infrastructure will be how countries display power – of all kinds – in the next era of space exploration. (The Conversation) GRS GRS
