New York City Manhole Exit Triggers Safety Warnings as Investigation Continues
Video shows about five people emerging from a Manhattan sewer manhole near Penn Station early Tuesday; the city DEP says the sewer is safe but entering sewers is illegal and hazardous, and police say it’s not yet known if this incident is connected to earlier Brooklyn cases. No arrests have been made and investigators are examining the situation.
NYPD Probes Video of Three Emerging from NYC Sewer by Penn Station
The NYPD is investigating a video showing three people in overalls with headlamps emerging from a manhole near Penn Station around 4 a.m. The Department of Environmental Protection inspected the sewer and found no structural damage. Similar underground sightings in Brooklyn and Queens earlier this year are being reviewed, but authorities say it’s not yet clear whether the incidents are connected.
Ivy-Covered Roof Hides an Underground Ohio Home on the Market
An earth-sheltered home in Huron, Ohio, built mostly underground with an ivy- and myrtle-covered roof that must be mowed, is listed for $850,000. The 2,100-square-foot ranch sits on about eight acres along the Huron River and features skylights, three bedrooms, two baths, and ample natural light. The property includes a gazebo, a log cabin, a workshop, and about 250 feet of waterfront, with a 30-minute boat ride to Lake Erie; its price reflects its unique, one-off nature with few local comps.
Giant 43-Foot Beam Makes 4,850-Foot Descent for DUNE's Underground Neutrino Lab
Crews are lowering 10 million pounds of steel into a former South Dakota gold mine for the Deep Underground Neutrino Experiment (DUNE). A 43-foot beam weighing about 15,890 pounds travels upright in a 4.5-foot-wide cage down the Ross Shaft 4,850 feet to form the two massive cryostats that will house 17,000 tons of liquid argon each. With more than 2,100 components needing to fit through the narrow shaft, the descent—done dozens of times this summer—is a critical, tightly choreographed step toward first neutrinos in 2031.
Trump touts massive underground complex beneath White House ballroom
Trump said the military is building a massive underground complex under the White House ballroom, which is under construction and ahead of schedule. The East Wing was demolished to make way for a $400 million ballroom, a plan that has drawn criticism; a preservationist lawsuit was rejected, and the National Capital Planning Commission is set to vote in April amid ongoing opposition.

Mexico’s Cave of Crystals: 11m Gypsum Giants Beneath a 58°C, 90% Humidity Hall
Mexico's Cave of Crystals in Chihuahua lies about 300 metres underground and holds gypsum crystals up to 11 metres long, earning it the nickname 'Sistine Chapel of crystals.' The cave formed as mineral-rich groundwater rose through rock after magma heated the area, stabilising at around 58°C, but with 90% humidity, making it deadly to explore without specialist equipment.
Toronto’s PATH: Navigating the Winter Underground That Keeps the City Moving
Toronto’s PATH is a 30-kilometer climate-controlled network of tunnels that connects offices, shops and transit, letting downtown workers and visitors dodge winter; while it’s no longer the Guinness World Records holder after Montreal’s RÉSO, the underground system is expanding as a “third space” with new businesses, and locals like Jadiel Teófilo are mapping it to help people navigate the maze.
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.
Scientists Discover Hidden Underground Cave in Chinese Sinkhole
Scientists have discovered an enormous underground cave system inside a giant sinkhole called Hong Kong Haiting Hall in Guangxi, China. The sinkhole, one of the largest ever recorded, measures 100 meters wide, nearly 200 meters long, and 118 meters deep, featuring complex caverns, underground rivers, and geological formations shaped over millions of years by water erosion and collapse. This remarkable discovery provides valuable insights into karst topography and geological processes.
US Strikes on Iran Spark Concerns Over Nuclear Program and Oil Supply
The US conducted air strikes on Iran's nuclear facilities, hitting some aboveground structures but possibly leaving underground enrichment sites, especially at Isfahan, largely intact, raising questions about the effectiveness of the operation in stopping Iran's nuclear capabilities.
"DIY YouTuber Constructs Budget-Friendly Bunker for Under $100K"
