A Stanford torus interior (cutaway view) Interior view of a large scale O'Neill cylinder, showing alternating land and window stripes. A space settlement (also called a space habitat, spacestead, space city or space colony) is a settlement in outer space, sustaining more extensively habitation facilities in space than a general space station or spacecraft.
In astrobiology and planetary astrophysics, the galactic habitable zone is the region of a galaxy in which life is most likely to develop. The concept of a galactic habitable zone analyzes various factors, such as metallicity (the presence of elements heavier than hydrogen and helium) and the rate and density of major catastrophes such as supernovae, and uses these to calculate which regions ...
Like the general circumstellar habitable zone, the continuously habitable zone of a star is divided into a conservative and extended region. [ 94 ] In red dwarf systems, gigantic stellar flares which could double a star's brightness in minutes [ 95 ] and huge starspots which can cover 20% of the star's surface area, [ 96 ] have the potential to ...
Cislunar space is a region outside of Earth that includes lunar orbits, the Moon's orbital space around Earth and the Earth-Moon Lagrange points. [ 104 ] The region where a body's gravitational potential remains dominant against gravitational potentials from other bodies, is the body's sphere of influence or gravity well, mostly described with ...
The human body was not built for spaceflight, with its microgravity conditions, exposure to high-energy radiation and other issues. As a result, trekking beyond the Earth's confines causes many ...
The ominous eye of Hurricane Milton is visible in stunning detail from outer space in a timeplapse video released Tuesday by NASA.. From 275 miles above Earth, the powerful storm can be seen ...
