The record-breaking rain that fell over the United Arab Emirates and Oman this month, triggering deadly floods and chaos, was driven partly by the climate crisis, according to a scientific analysis published Thursday, which pointed directly at humans burning fossil fuels.A team of 21 scientists and researchers, under the World Weather Attribution initiative, found that climate change was making extreme rainfall events in the two countries — which typically fall during El Niño years — between 10 and 40% more intense than they would have been without global warming.Over a period of less than 24 hours between April 14 and...

Earth's changing spin is threatening to toy with our sense of time, clocks and computerized society in an unprecedented way — but only for a second. For the first time in history, world timekeepers may have to consider subtracting a second from our clocks in a few years because the planet is rotating a tad faster than it used to. Clocks may have to skip a second — called a "negative leap second" — around 2029, a study in the journal Nature said Wednesday.

Scientists have found methane deep within Uranus - revealing the blue planet is gassier than previously thought. Early experiments of Uranus found the planet is primarily made up of Helium and hydrogen with a touch of methane, but a new study said it considerably outstrips previous expectations. What's odd about the methane though, is it isn't in gas-form but is frozen or 'mushy,' - like a 7-eleven Slurpee - and is lodged in Uranus's core. Researchers at the Israel Institute of Technology and University of California Santa Cruz revealed that despite findings that said Uranus is made up entirely of...

STORY: Volcanic vortex rings are natural, near-perfect circles of gas emitted from a volcano under specific conditions and scientists say Mount Etna emits more than any other volcano on earth. It is a relatively rare phenomenon caused by a constant release of vapours and gases. The gaseous mass ascends rapidly through the central part of the conduit, promoting the formation of rings by wrapping the gas upon itself in a vortex motion. Giuseppe Barbagallo, of the South Etna Alpine Guides Group, said the last time this happened at the Etna volcano was last December. The rings have led locals to...

It was a terrible quake that struck near Hualien City, Taiwan, just as the workday was beginning on Wednesday. Details aren't yet complete but, so far, nine people have been reported killed, over a thousand more injured, and 152 trapped in damaged buildings, quarries, and other places. At 7.4 on Richter Scale, the Hualien shifter was three times more powerful and released 5.6 times more energy than the 1989 Loma Prieta earthquake that dropped part of San Francisco's elevated Embarcadaro freeway, killed 63 people, and injured 3,757 more. “It was pretty scary,” a visiting American told NBC News. “In all...

Days before one of the researchers’ wedding, a star explodes in a once-in-a-lifetime occurrence.A team of Israeli scientists managed to capture and study a once-in-a-lifetime supernova using NASA’s Hubble Space Telescope, helping mankind better understand this magnificent event. Supernovas, or exploding stars, are phenomenons that occur in our galaxy about once every century, with the last observable explosion taking place hundreds of years ago. Supernovas can’t be predicted, and instead astrophysicists study their aftermath in a way reminiscent of space archaeology. But the researchers from the Weizmann Institute of Science learned about the supernova as it was taking place on...

Mars-caused changes in Earth’s orbit impacts ocean currents and temperatures every 2.4 million years and is known as an “astronomical grand cycle.” Anyone with an inkling of knowledge of geologic history appreciates Earth’s climate is constantly changing. This change has many reasons, including solar cycles, volcanic activity, and asteroids. New research shows another potentially significant player in Earth’s climate change cycles: Mars, our neighboring planet. Geological evidence tracing back more than 65 million years and taken from hundreds of sites across the world suggests that deep-sea currents have repeatedly gone through periods of being either stronger or weaker. This happens...

In the coming months, the world is set to witness an extraordinary celestial event as a massive explosion in the T Coronae Borealis star system is poised to create a “new star” in the night sky. This rare astronomical event, expected to occur between now and September 2024, is not the birth of a star but rather an extraordinary nova outburst from T Coronae Borealis (T CrB), situated 3,000 light-years away in the constellation of Corona Borealis. NASA described the anticipated nova outburst as a “once-in-a-lifetime viewing opportunity” as T Coronae Borealis is predicted to become as bright as the...

Explanation: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a...

Scientists have detected a 'great swarm' of earthquakes off the coast of Washington clocking as many as 200 in a single hour during one day. Geologists at the University of Washington said the quakes could lead to the Juan de Ruca Ridge erupting within a few weeks or years - but the effects are believed to be mild and not likely impact anyone on land. The underwater volcano sits more than 16,000 feet below the Pacific Ocean and about 150 miles off the coast of Washington. With more than a thousand tiny quakes detected in one day, this is the...

Archaeologists have unearthed a 3,300-year-old clay tablet depicting a catastrophic foreign invasion of the Hittite Empire in Büklükale, about 100 km from Turkey’s capital Ankara. A translation of the tablet’s cuneiform text indicates that the invasion occurred during a Hittite civil war, presumably in an attempt to support one of the fighting factions. Previously, only broken clay tablets had been found in the excavations at Büklükale, but this one is in almost perfect condition. Based on the typology and distribution of the collected pottery shards, Büklükale is thought to be a single-period city belonging to the Hittite Empire Period and...

Computer simulations reveal that the close flyby of Apophis, the "God of Chaos" asteroid, in 2029 still poses no risk to Earth, even when a worrying, previously unrecognized factor is taken into account. There is almost zero chance that the infamous city-killer asteroid "Apophis" will hit Earth when it zips closely past our planet in 2029 — even when a previously unconsidered factor is taken into account, a new study shows. Apophis is a peanut-shaped space rock spanning around 1,100 feet (340 meters) across that was left behind by the formation of the solar system around 4.6 billion years ago....

From the AI apocalypse to a full-blown nuclear war, it seems that there is an almost endless list of things that might cause the end of the world. But, if those terrifying fates gest us, there is one doomsday event that Earth can't avoid. A terrifying graphic reveals how the Sun will grow into a vast 'red giant' star, becoming so large that it will be the end of the solar system as we know it. Although this might seem utterly petrifying, you don't need to start worrying just yet. Dr Edward Bloomer, senior astronomer at Royal Observatory Greenwich, said:...

Greenland start-up is being accused of doing titanic damage to the environment by shipping ice from glaciers over 100,000 years old to be used in cocktails served at high-priced bars in Dubai. Arctic Ice, which started this year, touts its product as the “oldest and purest” ice in the world as it is harvested from icebergs in Greenland — a distance of more than 4,730 miles from the Middle Eastern megalopolis. Though the makers say they hope to highlight global warming’s effects on ice sheets with the their business model — and even stop sea levels from rising — the...

The Moon’s contraction causes fault scarps and moonquakes in the south pole, posing risks for lunar outposts. Findings from a recently published paper led by Smithsonian senior scientist emeritus Thomas R. Watters reveal evidence that the south polar region of Earth’s moon has experienced the effects of the shrinking moon. Global contraction of the moon has caused young lobate thrust fault scarps near and within some regions NASA has proposed for the crewed Artemis III moon landing. The paper, “Tectonics and Seismicity of the Lunar South Polar Region,” published recently in the Planetary Science Journal, associates one of the most...

Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier” — nicknamed because its collapse could cause catastrophic sea level rise. They have discovered it started retreating rapidly in the 1940s, according to a new study that provides an alarming insight into future melting. The Thwaites Glacier in West Antarctica is the world’s widest and roughly the size of Florida. Scientists knew it had been losing ice at an accelerating rate since the 1970s, but because satellite data only goes back a few decades, they didn’t know exactly when significant melting began. Now there is...

Yale University will once again require standardized testing for students applying for admission in the fall of 2025. The decision, announced today, ends the test-optional undergraduate admissions process that had been in place at Yale since the pandemic. According to the announcement, the past four years of test-optional admissions had given Yale what it described as “an invaluable opportunity to think deeply about testing policy and to generate new data and analyses. With testing availability now fully restored for prospective applicants around the world, we have reevaluated our policy with the benefit of fresh insights.” Yale is describing its new...

Astronomers have detected water molecules on the surface of asteroids for the first time, a surprising find given that the space rocks were thought to be “completely dry.” ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Water molecules have been detected on the surface of asteroids for the first time, proving that these remnants from the formation of our solar system aren’t just dried-up space rocks. Astronomers believe that the impact of asteroids crashing into our planet may have helped deliver water and other elements to early Earth, so finding evidence of water on asteroids could support that theory, according to a new study. The data was...

NEO 2003 SD220 on screen. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ How can humans protect the Earth from "devastating asteroid and comet impacts?" According to the National Academies and their 2023-2032 Planetary Science and Astrobiology Decadal Survey, ground based astronomical radar systems will have a "unique role" to play in planetary defense. There is currently only one system in the world concentrating on these efforts, NASA's Goldstone Solar System Radar, part of the Deep Space Network (DSN). However, a new instrument concept from the National Radio Astronomy Observatory (NRAO) called the next generation RADAR (ngRADAR) system will use the National Science Foundation's Green Bank Telescope...

Over a 17-year period, an international team of astronomers monitored Neptune’s atmospheric temperatures. They discovered that Neptune’s global temperatures dropped unexpectedly, followed by a dramatic warming at its south pole. Credit: ESO/M. Roman ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Using ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), an international team of astronomers track Neptune’s atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south pole. “This change was unexpected,” says Michael Roman, a postdoctoral research associate at the University of Leicester, UK, and lead author of the...
