A Nature Communications study using NASA’s Magellan radar data finds a giant subsurface lava tube beneath Venus’ Nyx Mons, about 1 kilometer in diameter and potentially extending at least 45 kilometers, providing the strongest direct evidence yet of Venusian lava tubes; confirming the full extent will require higher-resolution radar data.
Analysis of NASA's Magellan radar data suggests Venus may host a large underground lava tube on Nyx Mons, potentially stretching tens of kilometers. If confirmed, it would be only the second lava tube found on Venus and would support the view that the planet is geologically active; confirming its full size will require higher-resolution radar from future missions like ESA's EnVision with the Subsurface Radar Sounder.
The article examines the controversial legacy of 16th-century explorer Magellan, highlighting both his role in global exploration and the brutal treatment of indigenous peoples during his voyages, while also acknowledging his contributions to introducing Christianity to the Philippines.
Lav Diaz's film 'Magellan' explores the brutal and complex journey of Ferdinand Magellan, focusing on themes of discovery, imperialism, and violence, with a poetic and elliptical storytelling style that emphasizes the darker aspects of exploration.
Recent NASA data reveals Venus is still geologically active, with ongoing mantle plumes and volcanic activity, challenging previous beliefs that the planet was dormant. This discovery offers insights into planetary geology, early Earth processes, and the potential past habitability of Venus, with upcoming missions like VERITAS set to further explore these phenomena.
NASA's Magellan mission provided new insights into Venus's tectonic processes by studying coronae through gravity and topography data, revealing active subsurface interactions that may have occurred early in Earth's history. These methods will be useful for future Venus missions like VERITAS and EnVision, which will offer higher resolution data to further understand Venus's geology.
New research using decades-old radar images from NASA's Magellan spacecraft reveals that Venus is covered in thousands of volcanoes, some of which may still be active. This discovery reignites interest in studying Venus, leading to NASA's upcoming VERITAS mission to better understand the planet's volcanic activity and its implications for Earth.
New research reveals that Venus is covered in thousands of volcanoes, some of which may still be active, based on re-examined radar images from NASA's Magellan spacecraft from the early '90s. This discovery has reignited interest in Venus, leading to NASA's upcoming VERITAS mission to further study the planet's volcanic activity.
Oneok has agreed to acquire Magellan Midstream Partners in a cash-and-stock deal worth $18.8 billion, creating one of the largest oil and natural gas pipeline operators in the US. The deal includes $8.8 billion in new equity and the assumption of $5 billion of existing net debt. The acquisition will give Oneok access to a network of crude oil and refined products conduits and terminals sprawling from Texas to Minnesota. The transaction is expected to close in the third quarter, subject to shareholders and regulatory approvals.
New evidence suggests that Venus is volcanically active, based on radar images captured by NASA's Magellan spacecraft over 30 years ago. The images showed volcanic openings on the surface of Venus that appeared to change shape and size in less than a year, providing the first direct evidence of more recent volcanic activity on the planet. NASA's upcoming VERITAS mission is expected to study Venus from the surface to core in an effort to understand this rocky planet about the same size as Earth.
Geophysicist Robert Herrick of the University of Alaska, Fairbanks, has caught one of Venus's volcanoes in the act, providing the first clear evidence of volcanic activity on the planet. Venus's dense atmosphere makes it difficult to study its surface, but radar images from NASA's Magellan probe have revealed changes on the surface that can only be explained by volcanic activity. Future missions, such as NASA's Veritas and Esa's EnVision, will carry better imaging radar than Magellan and are expected to provide more information about Venus's volcanic activity.
