Our understanding of the Universe begins with the Big Bang, a moment in time where the Universe began expanding into what we see around us now.

Deepening stirling engine analysis: optimized model offers more accurate performance predictions
Multiple space agencies plan to return astronauts to the Moon by the end of this decade. Along with commercial and international partners, these efforts aim to create infrastructure that will ensure a "sustained program of lunar exploration and development." This includes NASA's Artemis Program, China's International Lunar Research Station (ILRS), and the ESA's Moon Village, all of which consist of creating lunar habitats around the South Pole-Aitken Basin.
