Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

Brighter Than 10 Trillion Suns: Record Black Hole Flare 10 Billion Light‑Years Away

Astronomers have observed the brightest and most distant black hole flare ever recorded, from AGN J2245+3743, 10 billion light-years away. The flare peaked at the brightness of about 10 trillion suns, likely caused by a supermassive black hole shredding a massive star. The event is roughly 30 times more powerful than previous records. Scientists continue to monitor the fading flare.

Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

A new study in Nature Astronomy sets a 2–5% image fidelity threshold for future black hole observations to distinguish Einstein’s black holes from alternatives. Simulations show that if upcoming telescopes like the upgraded Event Horizon Telescope or proposed missions reach this precision, they could rule out many rival gravity models. Current images remain consistent with Einstein’s theory.

Interstellar Comet 3I/ATLAS Stuns Scientists with Surprising Bright Outburst and Ancient Origins

Comet 3I/ATLAS, discovered July 1, 2025 by the ATLAS survey in Chile, is only the third known interstellar object to enter the solar system. The comet brightened rapidly as it passed the Sun on October 29, baffling astronomers and revealing strong outgassing of water vapor and carbon dioxide. It will not approach closer than 1.8 AU from Earth. Analyses suggest 3I/ATLAS may be nearly 10 billion years old.

  • 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.
