Wait, why is the White House using Starlink to ‘improve Wi-Fi’?
- The White House is using Starlink to address Wi-Fi connectivity issues caused by spotty cell service and overtaxed infrastructure.
- A SpaceX security engineer attempted to install Starlink on the roof of the White House complex, but triggered a Secret Service alarm.
- Using Starlink for improved Wi-Fi coverage raises ethics concerns and potential security implications.
- Instead of using another ISP, running new ethernet cable or adding more Wi-Fi access points could have been simpler solutions.

Those stranded NASA astronauts are finally coming home. Watch live as they fall back to Earth after 9 months in space.
- Two NASA astronauts who were stuck on the International Space Station for nine months are returning to Earth aboard SpaceX's Crew Dragon spaceship.
- The astronauts, Butch Wilmore and Suni Williams, were originally launched into space by Boeing's Starliner spaceship for a demonstration mission.
- The Starliner experienced engine glitches and was sent back to Earth empty, while Wilmore and Williams stayed on the ISS.
- The astronauts are expected to splash down off the coast of Florida after a fiery plummet back to Earth.

Did supernova explosions cause ancient mass extinctions on Earth?
- Scientists from Keele University have found strong evidence that some of Earth’s past mass extinctions could have been caused by nearby supernova explosions—massive star explosions in the Milky Way.
- The research team conducted a detailed survey of massive stars within about 3,260 light-years of the Sun, known as OB stars, to understand how galaxies and star clusters form.
- The study suggests that a nearby supernova could have stripped away Earth's ozone layer, exposing life to dangerous ultraviolet radiation and leading to mass extinctions.
- This research highlights the potential impact of cosmic events beyond Earth on the history of life and evolution.
