Corrosion in space is the corrosion of materials occurring in outer space.Instead of moisture and oxygen acting as the primary corrosion causes, the materials exposed to outer space are subjected to vacuum, bombardment by ultraviolet and X-rays, solar energetic particles (mostly electrons and protons from solar wind), and electromagnetic radiation.

Telluric iron, which is an iron-nickel alloy very similar to meteorites, also displays very coarse Widmanstätten structures. Telluric iron is metallic iron, rather than an ore (in which iron is usually found), and it originated from the Earth rather than from space. Telluric iron is an extremely rare metal, found only in a few places in the world.
A lance made from a narwhal tusk with an iron head made from the Cape York meteorite. Before the advent of iron smelting, meteoric iron was the only source of iron metal apart from minor amounts of telluric iron. Meteoric iron was already used before the beginning of the Iron Age to make cultural objects, tools and weapons. [8]
In 2014, Hari Kunduri and James Lucietti proved the existence of a black hole with Lens space topology of the L(2, 1) type in five dimensions, [2] this was next extended to all L(p, 1) with positive integers p by Shinya Tomizawa and Masato Nozawa in 2016 [3] and finally in a preprint to all L(p, q) and any dimension by Marcus Khuri and Jordan ...
The structures are listed based on their longest dimension. This list refers only to coupling of matter with defined limits, and not the coupling of matter in general (such as, for example, the cosmic microwave background, which fills the entire universe). All structures in this list are defined as to whether their presiding limits have been ...
Astronaut Sally K. Ride became the first American woman to visit space in June 1983. Calandrelli said she was crying on the flight home from the mission because of the online reaction and texting ...
Pietronero argues that the universe shows a definite fractal aspect over a fairly wide range of scale, with a fractal dimension of about 2. [3] The fractal dimension of a homogeneous 3D object would be 3, and 2 for a homogeneous surface, whilst the fractal dimension for a fractal surface is between 2 and 3.
History was made when Emily Calandrelli became the 100th woman to go to space and social media certainly had something to say about it — though not all the comments were positive. On November 22 ...
