Antarctic nunatak and the surrounding glacier that reveals surface details far beyond the reach of conventional optical satellites. Instead of relying on visible light, NISAR emits microwave pulses and records the echoes that bounce back from the...

to probe the solar corona, the outer atmosphere that fuels eruptions and streams charged particles capable of disrupting satellites, communication networks, and other Earth‑based technologies. In a fortuitous geometric coincidence, Proba‑3 had observed...

To bypass the errors associated with upstream measurements, the team analyzed over one million data points recorded by satellites orbiting in closer proximity to Earth. When these more accurate, localized readings were processed, the “saturation”...

The team modeled various initial conditions, adjusting Venus’s rotation speed from five to 100 hours and testing satellites ranging from 0.01 to 10 times the mass of Earth’s Moon. Their simulations revealed that while a moon could theoretically remain...

The findings, detailed in the journal Nature, were led by Alexander Byrne of the University of Arizona. While orbital satellites have long excelled at mapping the surface of Mars—identifying everything from ancient water traces to potentially habitable...

flow of volcanic debris. This capability marks a significant departure from traditional remote sensing. Unlike optical satellites that are often thwarted by dense cloud cover or the perpetual darkness of high-latitude winters, the NASA-ISRO Synthetic...

Society. “Space weather is often discussed as a modern challenge because of our dependence on technologies such as satellites, communications systems and electricity networks,” explained co-author Jim Wild of Lancaster University. “What this study shows...

via Satellite Radar Researchers from Pennsylvania State University utilized radar imagery captured by the Sentinel-1 satellites to monitor subtle ground deformations between 2018 and 2024. Their analysis, recently detailed in Geophysical Research...

that land directly on the Red Planet, this craft is designed to orbit and eventually touch down upon its two enigmatic satellites. Phobos, the larger and closer of the two moons, has long been a subject of intense scientific debate. Spanning roughly 22...

these magnetic structures is essential for better predicting solar storms, which can pose significant risks to satellites and critical infrastructure on Earth. Infographic illustrating the S-shaped magnetic switchbacks confirmed by Solar Orbiter in...

inside a protected zone of the inner magnetosphere, creating a previously underestimated radiation hazard for orbiting satellites. Challenging the Notion of an Impenetrable Barrier Earth’s radiation environment is dominated by the Van Allen belts, two...

dictates the timing and intensity of solar eruptions, having a 3D model could drastically improve our ability to protect satellites, power grids, and other critical infrastructure on Earth from solar storms. “For the first time, we can begin to see the...

Hurdles in High-Energy Astronomy Capturing these prolonged events is inherently challenging. Many monitoring satellites orbit in low Earth orbit, where they lose sight of target sources roughly every 90 minutes. While this is acceptable for short,...

New research may have finally solved the long-standing mystery of why Venus lacks a moon, offering fresh insights into the planet’s chaotic orbital history. For decades, planetary scientists have wrestled with a curious cosmic discrepancy: why does...

A long‑silent volcano near Iran’s border is awakening, exposing a hidden magma buildup that scientists warn authorities cannot ignore. A quiet swelling has been recorded on the summit of Taftan, the 3,940‑metre‑high stratovolcano perched on the...

NASA has awarded a $700 million contract for an untested spacecraft platform that could determine the timeline for the first human mission to Mars. NASA has tapped Blue Origin for a $700 million contract to develop a dedicated telecommunications...

Scientists have detected a massive 37.5 million-ton bloom of Sargassum seaweed stretching across the Atlantic Ocean, from West Africa to the Gulf of Mexico. For decades, the presence of Sargassum in the Atlantic was a predictable, albeit fluctuating,...

Satellite data reveals unexpected ground movements at a famous lava-lake volcano, forcing scientists to rethink what is happening deep underground. Researchers have identified two previously unknown magma sources beneath Nicaragua’s Masaya volcano,...

Archaeologists have uncovered an ancient Egyptian engineering secret that explains how a massive structure survived for 2,600 years on unstable ground. Archaeologists working in the northwestern Nile Delta have uncovered a massive, 2,600-year-old...
