The Dirty Afterlife of a Dead Satellite
Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations.universetoday.com - If the universe is expanding, how can galaxies collide?
How can galaxies ever collide in an ever-expanding universe?
You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome even the stretching of space itselfscientificamerican.com - Snakes on a train? King cobras may be riding the rails in India

Sophie Adenot ready for first space mission
Video: 00:03:58 ESA astronaut Sophie Adenot is preparing to launch to the International Space Station for her first space mission: εpsilon . After years of intensive training — from emergency procedures to spacewalk simulations — the countdown has begun. Flying alongside astronauts from NASA and Roscosmos, Sophie will join an international crew living and working together in space. Aboard the ISS, Sophie will live and work in microgravity, conducting scientific research and performing a range of European- and French-led experiments that advance knowledge for life on Earth and in space. Join us live on YouTube to watch the launch of Sophie Adenot.esa.int - Earth from Space: Olympic view

Le concept d’OpenClaw, un assistant open source capable de tout faire – ou presque – à votre place est séduisant. Du moins tant qu’on ne réfléchit pas aux conséquences ; la nouvelle folie des data centers dans l’espace. Et aussi : quand la mort se trompe de jour.pourlascience.fr
