“These are among the smallest signals detected by the Swarm mission so far,” Alexander Grayver, a geophysics researcher at the University of Cologne in Germany, said in the statement. “The data are particularly good because they were gathered during a period of solar minimum, when there was less noise due to space weather.”

The Swarm mission has already passed its expected end of life, but researchers hope the satellites will remain operational until the next solar minimum, which will come at around 2030.

The study was published in the journal Philosophical Transactions of the Royal Society A in December 2024.

NISAR, an upcoming Earth satellite mission by NASA

NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for the nation’s civilian space program and for aeronautics and aerospace research. Established in 1958 by the National Aeronautics and Space Act, NASA has led the U.S. in space exploration efforts, including the Apollo moon-landing missions, the Skylab space station, and the Space Shuttle program.

A study led by researchers from the University of Virginia has used satellite measurements to show the long-term persistence of air pollution inequalities tied to industrialized swine facilities in Eastern North Carolina.

Using spanning a 15-year period from 2008–2023, the study quantifies disparities in ammonia (NH3)—an air pollutant emitted by swine operations—for Black, Hispanic and Indigenous communities. These inequalities, exacerbated by hot and calm weather conditions, extend for multiple kilometers beyond the immediate vicinity of the facilities, highlighting the widespread impact of this environmental issue.

The study, published in Environmental Science & Technology by Sally Pusede and her team in the Department of Environmental Sciences at UVA, uses data from the Infrared Atmospheric Sounding Interferometer (IASI) aboard multiple polar-orbiting satellites. By analyzing NH3 levels in the atmosphere, UVA researchers were able to show that emissions from industrial swine operations result in systematic environmental inequalities.

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter. In a collaboration between the University of Queensland, Australia, and Germany’s metrology institute (Physikalisch-Technische Bundesanstalt, PTB), the team used data from atomic clocks and cavity-stabilized lasers located far apart in space and time to search for forms of dark matter that would have been invisible in previous searches.

This technique will allow the researchers to detect signals from dark matter models that interact universally with all atoms, an achievement that has eluded traditional experiments.

The team analyzed data from a European network of ultra-stable lasers connected by fiber (previously reported in a 2022 article), and from the aboard GPS satellites. By comparing across vast distances, the analysis became sensitive to subtle effects of oscillating dark matter fields that would otherwise cancel out in conventional setups.

Smaller than a strawberry seed, this tiny signal amplifier was produced by the European Space Agency to fill a missing link in current technology, helping to make future radar-observing and telecommunications space missions feasible.

“This integrated circuit is a low noise amplifier, measuring just 1.8 by 0.9 mm across,” explains ESA microwave engineer David Cuadrado-Calle. “Delivering state of the art performance, the low noise amplifier’s task is to boost very faint signals to usable levels.”

It could in the future be employed for both radar-based missions—where the faint signals are the radar echoes received by the instrument after they bounce off Earth’s surface and travel back to the satellite—and telecommunications —where the communication signals coming from Earth are amplified by the satellite and sent back to Earth for broadband access or broadcasting services.

Watch Firefly Aerospace’s Blue Ghost lunar lander lift off from NASA’s Kennedy Space Center in Florida on a SpaceX Falcon 9 rocket. SpaceX and Firefly Aerospace are targeting 1:11 a.m. EST (0611 UTC) Wednesday, Jan. 15, 2025, for launch. The lander will carry 10 NASA science investigations to the Moon’s surface.

Following launch, the lander will spend approximately 45 days in transit to the Moon before landing on the lunar surface in early March 2025. The 10 NASA payloads aboard the lander aim to test and demonstrate lunar subsurface drilling technology, regolith sample collection capabilities, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation methods.

The results of these investigations could help further our understanding of the Moon’s environment and help prepare for future human missions to the lunar surface as part of the agency’s Moon to Mars exploration approach.

An international team of astronomers has reported the detection of a new exoplanet orbiting a bright late F-type star. The newfound alien world, designated TOI-6038 A b, is about six times larger and nearly 80 times more massive than Earth. The finding is detailed in a paper published Jan. 4 on the arXiv preprint server.

NASA’s Transiting Exoplanet Survey Satellite (TESS) is conducting a survey of about 200,000 of the brightest stars near the sun with the aim of searching for transiting exoplanets. So far, it has identified nearly 7,400 candidate exoplanets (TESS Objects of Interest, or TOI), of which 591 have been confirmed so far.

Now, a group of astronomers led by Sanjay Baliwal of the Physical Research Laboratory (PRL) in Ahmedabad, India, reports the confirmation of another planet monitored by TESS. Baliwal’s team has identified a transit signal in the light curve of TOI-6038 A—a late F-type star about 578 light-years away. The planetary nature of this signal was validated by follow-up observations using the 2.5m telescope at the PRL Observatory in India.

Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds.

These are one of nature’s most powerful particle accelerators and have long intrigued scientists for the role they play in producing that travel across vast distances in space.

The research, published in Nature Communications, combines satellite observations from NASA’s MMS (Magnetospheric Multiscale) and THEMIS/ARTEMIS missions with recent theoretical advancements, offering a comprehensive new model to explain the acceleration of electrons in collisionless shock environments.

Over the last few years, artificial intelligence (AI) has been firmly in the world’s spotlight, and the rapidly advancing technology can often be a source of anxiety and even fear in some cases. But the evolution of AI doesn’t have to be an inherently scary thing — and there are plenty of ways that this emerging technology can be used for the benefit of humanity.

Writing in “AI for Good” (Wiley, 2024), Juan M. Lavista Ferres and William B. Weeks, both senior directors at Microsoft’s AI for Good Research Lab, reveal how beneficial AI is being used in dozens of projects across the world today. They explain how AI can improve society by, for example, being used in sustainability projects like using satellites to monitor whales from space, or by mapping glacial lakes. AI can also be used in the wake of natural disasters, like the devastating 2023 earthquake in Turkey, or for social good, like curbing the proliferation of misinformation online. In addition, there are significant health benefits to reap from AI, including studying the long-term effects of COVID-19, using AI to manage pancreatic cysts or detecting leprosy in vulnerable populations.

In this excerpt, the authors detail the recent rise of large language models (LLMs) such as ChatGPT or Claude 3 and how they have grown to become prominent in today’s AI landscape. They also discuss how these systems are already making a significant beneficial impact on the world.
