A colossal structure in the distant Universe is defying our understanding of how the Universe evolved.
In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, almost perfect ring of galaxies, some 1.3 billion light-years in diameter. It doesn’t match any known structure or formation mechanism.
The Big Ring, as the structure has been named, could mean that we need to amend the standard model of cosmology.
A research team has developed the world’s first next-generation betavoltaic cell by directly connecting a radioactive isotope electrode to a perovskite absorber layer. By embedding carbon-14-based quantum dots into the electrode and enhancing the perovskite absorber layer’s crystallinity, the team achieved both stable power output and high energy conversion efficiency.
The work is published in the journal Chemical Communications. The team was led by Professor Su-Il In of the Department of Energy Science & Engineering at DGIST.
The newly developed technology offers a stable, long-term power supply without the need for recharging, making it a promising next-generation energy solution for fields requiring long-term power autonomy, such as space exploration, implantable medical devices, and military applications.
A giant object that has been lurking in the relative galactic vicinity of the Solar System this entire time has just been unmasked in all its enormous, invisible glory.
Just 300 light-years away, at the edge of the Local Bubble of space, astronomers have discovered a huge, crescent-shaped cloud of molecular hydrogen, the basic building block of everything in the Universe.
It’s the first time scientists have managed to discover molecular material in interstellar space by looking for the glow of far-ultraviolet light. Its discoverers have named the cloud Eos, after the ancient Greek goddess of the dawn.
“Second Variety” is a science fiction novelette by American writer Philip K. Dick, first published in Space Science Fiction magazine, in May 1953. Set in a world where war between the Soviet Union and United Nations has reduced most of the world to a barren wasteland, the story concerns the discovery, by the few remaining soldiers left, that self-replicating robots originally built to assassinate Soviet agents have gained sentience and are now plotting against both sides. It is one of many stories by Dick to examine the implications of nuclear war, particularly after it has destroyed much or all of the planet. The story was adapted into the movie Screamers in 1995. 00:00 Intro 01:03 Peek into the plot 03:33 Self-Replication and Technological Autonomy 06:51 Current Autonomous Warfare Capabilities 10:30 Space Warfare and the Projection of Terrestrial Conflict 13:14 Current State of Space Warfare 15:22 Wrapping Up =============== 🎬 Loitering munitions system WARMATE • Loitering munitions system WARMATE 📙 🇺🇸 Superintelligence: Paths, Dangers, Strategies https://bookshop.org/a/98861/97801987… The Human Terrain Project — PENTAGON’S attempt to understand The Enemy | ENDEVR Documentary
