Space travel has taught us valuable lessons for living and working in outer space, specifically regarding how microgravity (often mistakenly called zero-gravity) impacts the human body during short- and long-term spaceflight. This includes decreased muscle and bone mass, fluid shifts, reduced heart rate, psychological health, compromised immune system, and radiation exposure. But with agencies like NASA aspiring to build a lunar base and establish a long-term presence on the Moon, and eventually Mars, how could space travel impact potentially having babies in space? from Universe Today https://ift.tt/xFj7JAp via IFTTT
The Milky Way has a sizable retinue of dwarf galaxies, and they may hold important clues about conditions in the early Universe. However, they're difficult to observe because many of them are so faint. The tiniest ones are called Ultra-faint dwarf galaxies, and a new simulation aimed at how they form is showing how these faint collections of stars and gas mirror the conditions of the early Universe. from Universe Today https://ift.tt/CHYkVxX via IFTTT
