Hidden Lava Tubes Hint at a Subsurface Network Beneath Venus

Researchers analyzing radar data from the Magellan mission detected what appears to be a large underground lava tube beneath Venus, near the Nux Mons region. The tube is about 1 kilometer wide, with a roof around 150 meters thick and a hollow cavity at least 375 meters high, marking the first confirmed subsurface feature on Venus and supporting long-held ideas about the planet’s volcanic activity. If confirmed, there may be more tubes beneath Venus’ surface, a task for upcoming radar-focused missions VERITAS and EnVision, planned to launch around 2031.

Venus Unveils Its Largest Known Lava Tube

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.

Biomass satellites frees its data stream to illuminate global forest carbon

ESA’s Biomass, a P-band radar satellite launched in 2025, has completed commissioning and now offers free, public access to its data to map forest structure and carbon storage. The mission begins with an 18-month global tomographic coverage, followed by multiple nine-month interferometric coverages to monitor forest change over time, with an airborne calibration campaign in Gabon aiding data validation and calibration. The effort aims to reduce uncertainties in global forest carbon stocks and support climate science and forest management.

Borderlands 4 Introduces Exciting New Feature Amid Minimap Changes

Gearbox has added a radar feature to Borderlands 4, responding to fan requests, which will help players with situational awareness. The radar, a departure from the mini-map, was developed quickly by the team and will be available at launch in September, with other fan-requested features also included. The game will launch on PC, PS5, and Xbox Series X|S, with a Switch 2 version coming later.

Cold War Ice Base Uncovered by NASA Radar

NASA scientists, using advanced radar technology, have rediscovered Camp Century, a Cold War-era U.S. military base buried beneath Greenland's ice. Originally constructed in 1959 for nuclear missile testing, the base was abandoned in 1967 and now lies under nearly 100 feet of ice. The discovery raises concerns about potential environmental hazards if melting ice exposes the base's remnants, including radioactive waste. The radar imagery, obtained by chance, highlights the importance of understanding ice sheet dynamics in the context of climate change.

"Michigan Counties on Alert: Severe Storms and Tornadoes Expected"

A severe thunderstorm watch is in effect for most of southern Lower Michigan until 7 p.m., with a fast-moving line of severe storms already formed and moving east across the region. The storms are expected to hit quickly and be over rapidly, with the most severe part lasting only a few minutes. The main threats include brief gusts of around 60 mph, large hail, and the possibility of isolated tornadoes. Residents are advised to seek shelter indoors and stay updated on the rapidly changing radar imagery.

"Severe Storms Threaten Ohio: Tornado Watch Issued for Multiple Regions"

A Tornado Watch is in effect for central, northern, and western Ohio until 7 p.m., with the potential for strong to severe storms later in the day. Morning rain is expected to give way to partly cloudy skies and temperatures in the upper 70s, with brisk winds aiding in temperature increase. Severe storms with damaging winds, large hail, and isolated tornadoes are possible, particularly in Northern Ohio. Showers and storms are likely early Friday, followed by a cool and dry weekend.

"Northeast Braces for Blustery Winter Storm with Strong Winds and Heavy Snow"

Wet snow and strong wind gusts will create hazardous driving conditions overnight and into Monday morning in Westvale, NY, with snow-covered, slippery roads and significant blowing snow. Winter weather and wind alerts are in effect, with conditions expected to improve by late afternoon. Snowfall accumulations will vary depending on elevation, and meteorologist Sam Postitch will provide live updates on NBC3 and CBS5 starting at 4 a.m.

"Using Radar to Detect Hazardous Asteroids"

Ground-based radar systems, such as NASA's Goldstone Solar System Radar and the National Radio Astronomy Observatory's (NRAO) next-generation RADAR (ngRADAR) system, could play a crucial role in detecting and tracking potentially threatening asteroids and comets. These systems have the potential to significantly impact asteroid detection and planetary defense efforts. With over 1.1 million known asteroids in the solar system, the ability to detect and track Near-Earth Objects (NEOs) is crucial for protecting Earth from potential impacts. Radar technology not only aids in asteroid detection but also provides detailed insights into the solar system's geology, making it a valuable tool for planetary scientists.

"Ukraine's Strategic Strikes: How Downed Russian Planes Weaken Moscow's Radar Coverage"

Ukrainian forces have been successfully targeting and shooting down Russian A-50 radar-early-warning planes, which has created gaps in Russian radar coverage over Ukrainian airspace. This has forced the Russian air force to make difficult decisions about which regions of the front line will no longer receive airborne radar coverage. The ongoing campaign of deep strikes by Ukraine has underscored the importance of the A-50s, and as the Ukrainians exploit these gaps, it remains to be seen how the Kremlin will respond and how the Ukrainians will take advantage of the situation.

"Ukraine's Ongoing Struggle: A Look from Space to Putin's Loss"

Scientists are using radar data from satellites to monitor the destruction caused by the war in Ukraine, providing a safe and unbiased means to study inaccessible or dangerous areas. By analyzing radar coherence before and after the war, they have flagged highly damaged areas and revealed the extensive devastation in cities such as Bakhmut, Rubizhne, Sievierodonetsk, and Lysychansk. This remote sensing approach offers unimpeded access to high-resolution, unbiased information, helping people grasp the true impact of war on the ground.

"Winter Storm Shifts Southward, Westchester County Declares State of Emergency"

Heavy snow is reported across several counties in the Hudson Valley, with mesoscale banding indicating potential for 1-2” per hour snowfall rates and a sharp northern cutoff. Ground reports show snowfall in southern zones while areas just 10 miles north only have clouds, prompting continued monitoring of the snow edge's northward push. Forecast models and radar data suggest potential for overperformance in certain areas, with 6”-10” amounts possible in locations under the bands.

"Winter Storm Alert: Icy Conditions Threaten Midwest and Northeast"

Temperatures across the Hudson Valley have risen above freezing, but as the sun sets, icy conditions could develop, especially in areas north of I-84 experiencing light to moderate wet snow. Areas south of that line are mainly dry, but precipitation is expected to fill back in before midnight. With temperatures falling closer to freezing, icy spots are possible, particularly on bridges and overpasses. The atmosphere will cool from north to south through the afternoon, resulting in rain changing to snow or staying mixed in the southernmost areas. Icing may begin as temperatures dip below 32°F, creating a layer of ice under any snow or ice that falls on top of it.

"Winter Storm Alert: Multiple Rounds of Freezing Rain to Impact Travel in Chicago and Oklahoma"

A Winter Weather Advisory is in effect for parts of the Chicago area, including central, northern, and southern Cook, as well as Lake and McHenry counties in Illinois, and several counties in Indiana, due to the possibility of slick roads from light snow and freezing rain. The Chicago Department of Streets and Sanitation has salt spreaders out, and power outages are possible south of Interstate 80. Warming centers have been activated in Chicago, and the area is expected to experience challenging weather following heavy snowfall in northwest Indiana.
