A faint electric field has been detected in Earth’s atmosphere, confirming a theory that scientists have held for decades. This ambipolar electric field, though weak at just 0.55 volts, could play a vital role in shaping Earth’s atmospheric evolution and its ability to support life, according to recent findings. Glyn Collinson, an atmospheric scientist at

An increase in solar activity has resulted in the early re-entry of three CubeSats from Curtin University’s Binar Space Program. These small satellites, which operated at low Earth orbit, were designed to last for at least six months. However, due to intensified solar conditions, they were destroyed within two months, significantly shortening their scientific mission.
NASA astronaut Sunita Williams has recently addressed speculations surrounding her health condition while on the International Space Station (ISS), discarding recent claims made by media outlets regarding her wellbeing. In response to reports that suggested she appeared “gaunt” due to an extended stay on the ISS, Williams clarified her status during a video interview on
Scientists at Penn State University have identified that microplastics present in the atmosphere could be influencing the Earth’s climate. A study published in Environmental Science and Technology: Air reveals that these tiny plastic particles may act as ice nucleating agents within clouds, impacting precipitation, weather, and possibly even aviation. Although the precise effects remain unclear,
A recent analysis of 38-year-old data from NASA’s Voyager 2 spacecraft has provided fresh insights into the unique magnetosphere of Uranus, according to a study published on November 11 in Nature Astronomy. During Voyager 2’s 1986 flyby, Uranus’ magnetosphere was found to be unexpectedly distorted by a blast of solar wind. The findings suggest that
A recent discovery at the Indian Institute of Science (IISc) offers an energy-efficient method to achieve glassy transformations in indium selenide, a material that could change the face of data storage technology. The study was conducted in a collaboration between the University of Pennsylvania and the Massachusetts Institute of Technology (MIT). The research demonstrates that
Chimpanzees have shown improved performance on challenging computer-based tasks when observed by humans, a study published in iScience on November 8 reveals. Conducted at Kyoto University, the research observed chimpanzees undertaking number-based tasks on touchscreens, monitored under different audience conditions. It was found that their performance increased with the task’s difficulty when the number of
Research from Virginia Tech has highlighted sewage surveillance as a powerful tool in addressing antimicrobial resistance (AMR). This method, tested across numerous countries, appears more effective than individual testing, particularly in tracking resistant bacteria in communities facing limited resources. The study was published in Nature Water and it suggest that by monitoring sewage, public health
NASA’s experimental X-59 Quiet SuperSonic Technology (Quesst) aircraft has reached a crucial testing milestone with its engine fired up for the first time. Since late October, engineers at Lockheed Martin’s Skunk Works facility in Palmdale, California, have been carrying out phased engine tests to evaluate the X-59’s performance and systems integration. These tests mark a
A study has shown that the well-preserved fossil of a nodosaur, a plant-eating dinosaur, could withstand the force of a high-speed car crash. The fossil, discovered in Alberta, Canada, belongs to Borealopelta markmitchelli , a species that lived around 110 million years ago during the Early Cretaceous period. This fossil is one of the best-preserved
New research has revealed that meteoroid trails, left behind by long-period comets, could help scientists detect potentially hazardous comets years before they approach Earth. These rare comets, which take hundreds or even thousands of years to complete their orbits, often go unnoticed until it is too late to prepare for a possible collision. However, scientists
Russia successfully launched a record-setting 53 satellites into space on November 4, 2024, achieving a major milestone in satellite deployment. This launch, managed by the Russian space agency Roscosmos, included a combination of domestic and international satellites. A Soyuz-2.1b rocket with a Fregat upper stage was used for the mission, lifting off from the Vostochny
Martian impact basins, previously assumed to be demagnetised due to an inactive planetary dynamo, may instead reflect the impact of a reversing magnetic field, a new study suggests. Led by Dr Silpaja Chandrasekar, PhD, indicates that Mars’s fluctuating dynamo may have been active longer than anticipated, with implications for understanding planetary evolution. Impact Basins and
Primordial black holes (PBHs), possibly formed shortly after the Big Bang, may be experiencing explosive events across the universe. A recent study led by theoretical physicists Dr Marco Calzà and Dr João G. Rosa from the University of Coimbra proposes that these eruptions, driven by Hawking radiation, could be detectable with the advanced sensitivity of
In 2013, a team led by Ning Zeng, a climate scientist from the University of Maryland, unearthed a remarkable find while conducting an experiment in Quebec, Canada. The researchers were digging a trench to test if burying wood under clay soil could prevent its decomposition and keep carbon locked away from the atmosphere. During this
Astronomers are watching two unusual black holes, each presenting phenomena that challenge current understanding of these cosmic giants. One, a “serial killer” black hole, is about to devour its second star within five years, while the other, part of the newly discovered triple system V404 Cygni, has disrupted long-held theories of black hole formation. The
NASA’s Parker Solar Probe will make a close approach to Venus on Wednesday, marking the spacecraft’s seventh and final flyby of the planet. This manoeuvre will set the probe on a course for its historic plunge toward the sun, bringing it within 3.8 million miles of our star’s surface — closer than any human-made object
NASA’s asteroid-hunting spacecraft, NEOWISE, has officially concluded its journey, meeting its end as it re-entered Earth’s atmosphere and burned up on 1 November. Over its 15-year lifespan, NEOWISE catalogued nearly 3,000 near-Earth objects, including numerous asteroids, providing critical data for researchers studying potential planetary threats. The space agency confirmed NEOWISE’s re-entry on social media the
Indian scientists have achieved an important milestone in solar research, reporting the first major findings from the Visible Emission Line Coronagraph (VELC) aboard India’s Aditya-L1 mission. The solar mission, launched by the Indian Space Research Organisation (ISRO) in September 2023, is India’s first dedicated solar observation project positioned at the Lagrange Point 1 (L1). This
A team of astronomers, using data from NASA’s James Webb Space Telescope (JWST) and the Chandra X-ray Observatory, has identified a black hole consuming matter at a record-breaking rate in a young galaxy. Named LID-568, this black hole is found in a galaxy thought to have formed only 1.5 billion years after the Big Bang.
