Interstellar Comet 3I/ATLAS: Latest Discoveries, Alien Debate and How to See It in December 2025

Interstellar Comet 3I/ATLAS: Latest Discoveries, Alien Debate and How to See It in December 2025

Interstellar comet 3I/ATLAS is making its closest approach to Earth in December 2025, passing at about 1.8 AU and displaying powerful jets and a 16-hour light pulse. NASA and ESA confirm it poses no threat and are using the event for planetary-defense drills. The comet’s nucleus measures between 440 meters and 5.6 km, and its age is estimated at 7 billion years. Some speculate about alien technology, but scientists remain cautious.

Chernobyl’s ‘Radiation‑Eating’ Black Fungus Could Help Protect Astronauts on the Moon and Mars

Chernobyl’s ‘Radiation‑Eating’ Black Fungus Could Help Protect Astronauts on the Moon and Mars

A black fungus thriving inside Chernobyl’s reactor, Cladosporium sphaerospermum, has drawn global attention after new research confirmed its melanin can shield plastics from space radiation. Scientists first identified the fungus in the 1990s, noting its unusual growth toward radioactive material. NASA has already tested similar fungi on the International Space Station as a potential radiation barrier.

  • Planet Labs Nears Sustainable Profitability Amid Industry Challenges
    May 21, 2026, 3:12 PM EDT. Planet Labs (PL) operates a vast network of Earth observation satellites capturing global images daily. Despite technological advances and expanded roles in defense and agriculture, the company has yet to secure steady profits due to high costs in satellite manufacturing, launches, maintenance, and R&D. Revenue growth lags behind fixed costs, while long government sales cycles delay cash flow. Management's 2026 guidance shows optimism, focusing on cost control, vertical specialization, and software monetization to enhance margins. Industry peers Rocket Lab (RKLB) and BlackSky Technology (BKSY) face similar profitability challenges. PL's stock has surged 117% year-to-date but trades at a lofty price-to-sales ratio of 31.38, far above the industry average of 3.86, reflecting high investor expectations amid ongoing financial pressures.
