Strange radio waves detected beneath Antarctica's ice, scientists still searching for the source
A team of researchers working in Antarctica has detected unusual radio signals emerging from deep beneath the ice. These waves were picked up during an experiment using the Antarctic Impulsive Transient Antenna (ANITA), a NASA-funded project that searches for high-energy particles from space. Tired of too many ads? go ad free now The discovery was unexpected as the signals appeared to be coming from below the surface rather than from space. Scientists say the waves are unlikely to be caused by known particles like neutrinos and have yet to determine exactly what is producing them. Radio waves found during neutrino search in Antarctica The ANITA experiment was designed to study high-energy neutrinos using a balloon that carried radio instruments into the stratosphere. Antarctica was chosen as the site due to its isolation and low interference from other radio sources. While searching for neutrinos researchers came across signals coming from around 30 degrees below the ice surface. These signals were unexpected because they would have had to pass through thousands of kilometres of rock which should have absorbed them completely. Neutrinos ruled out as the cause Stephanie Wissel, an astrophysicist at Penn State University and part of the ANITA team, explained that the signals were not consistent with neutrinos. Neutrinos are incredibly difficult to detect and rarely interact with matter. Although they can travel great distances through solid rock the angles and nature of the signals did not match what scientists expect from neutrino interactions. The team also cross-checked their findings with data from two other experiments and found no matches confirming that these were not neutrino events. Theories and unanswered questions around the mystery Since neutrinos were ruled out scientists are now considering other explanations. Tired of too many ads? go ad free now Some have proposed the signals could be related to dark matter or unknown radio wave behaviour around the ice and the horizon. However none of these theories have been confirmed. Wissel said that while they have explored several ideas none fully explain what was detected. She added that more experiments and data will be needed to understand what is happening under the Antarctic ice. Search continues for the mysterious source The instruments used in the experiment were lifted about 40 kilometres into the sky to capture faint radio emissions. While this approach allows for a broad view of signals entering Earth from space it also reveals unexpected activity from below. As scientists continue to review the data and prepare for future missions they hope to uncover more about the nature of these strange signals. For now the source of the radio waves remains a mystery.

'City killer' asteroid, headed earlier for Earth, now set to hit moon in 2032? NASA's latest update
Asteroid 2024 YR4, which was earlier seen as a threat to Earth, now appears to be on a collision course with the moon. Since its discovery last year, the asteroid had caught the attention of the world after it was revealed there was a slim possibility it might hit the Earth in 2032. Experts at the National Aeronautics and Space Administration (NASA) Center for Near Earth Object Studies have updated the 2024 YR4's chance of hitting the Moon in 2032 to 4.3 per cent. According to NASA, the possibility of 2024 YR4 hitting the moon was updated after data from the James Webb telescope and other ground-based telescopes. 'The Webb data improved our knowledge of where the asteroid will be on December 22, 2032, by nearly 20%. As a result, the asteroid's probability of impacting the Moon has slightly increased from 3.8% to 4.3%. In the small chance that the asteroid was to impact, it would not alter the Moon's orbit,' a post on NASA's blog read. According to NASA, the asteroid is now too far away to observe with telescopes. Further observations will be conducted by the US space agency in 2028, when the asteroid's orbit around the Sun brings it back closer to Earth. As data comes in, the probability of the asteroid's impact may change. An international team led by Maryland-based Dr. Andy Rivkin of the Johns Hopkins University Applied Physics Laboratory, made the observations about the asteroid in May using Webb's near-infrared camera. When the asteroid was first discovered in 2024, it had a very low probability of impacting the Earth. After investigation, NASA concluded that the asteroid would not pose a significant impact risk to the planet in 2032 and beyond. When the asteroid was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ALERT), it was called 'city destroyer' online due to its speed, size, and the possibility of it hitting the Earth. It was discovered on December 27, 2024, by the Asteroid Terrestrial-impact Last Alert System. The asteroid is about 40 to 90 meters (130 to 300 feet) wide. As of now, there is no significant impact risk posed by the asteroid in 2032.

European Space Agency's new asteroid hunter opens its eye to sky
10 June 2025 12:03 SICILY (ALETIHAD) The European Space Agency's (ESA) newest planetary defender has opened its 'eye' to the cosmos for the first time. The Flyeye telescope's 'first light' marks the beginning of a new chapter in how to scan the skies for new near-Earth asteroids and by an insect's compound eye, ESA and OHB Italia designed Flyeye to capture a region of the sky more than 200 times as large as the full Moon in a single exposure – much larger than a conventional will use this wide field of view to automatically survey the sky each night independent from human operation and identify new asteroids that could pose a hazard to Earth. 'In the future, a network of up to four Flyeye telescopes spread across the northern and southern hemispheres will work together to further improve the speed and completeness these automatic sky surveys and to reduce the dependence on good weather at any individual site,' said ESA's Ernesto Doelling, Flyeye Project Manager.'The earlier we spot potentially hazardous asteroids, the more time we have to assess them and, if necessary, prepare a response,' said Richard Moissl, Head of ESA's Planetary Defence Office. 'ESA's Flyeye telescopes will be an early-warning system, and their discoveries will be shared with the global planetary defence community.'ESA's Near-Earth Object Coordination Centre (NEOCC) will verify any potential new asteroid detections made by the Flyeye telescopes and submit the findings to the Minor Planet Centre, Earth's hub for asteroid observational data. Astronomers, including experts from the NEOCC, will then carry out follow-up observations to further assess the hazard that the object may Aceti, Managing Director at OHB Italia, explained, 'The unique optical design of the Flyeye telescope is optimised for conducting large sky surveys while maintaining high image quality throughout the wide field of view."He added that the telescope is equipped with a one-metre primary mirror, which efficiently captures incoming light. This light is then divided into 16 separate channels, each equipped with a camera capable of detecting very faint objects. This enables simultaneous high-sensitivity observations over a large region of the sky. During operations, Flyeye's observation schedule will be optimised to consider factors such as Moon brightness and the work of other survey telescopes such as the NASA-funded ATLAS telescopes, the Zwicky Transient Facility and the upcoming Vera Rubin Telescope.
