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.

In these materials, the two polarizations split according to their effective refractive indices, which are also sensitive to stress. The study of birefringence in shear waves traveling through the solid Earth (the Earth's liquid core does not support shear waves) is widely used in seismology. [citation needed]
Extraterrestrial material refers to natural objects now on Earth that originated in outer space. Such materials include cosmic dust and meteorites , as well as samples brought to Earth by sample return missions from the Moon , asteroids and comets , as well as solar wind particles.
Images revealed previously unseen crescent-like structures in the SN 1987A supernova and its remnant 168,000 light years from Earth, thought to be part of the outer layers of gas from the ...
Polish media said the composite material found near Poznan resembled a Falcon 9 fuel tank. Researchers warned in a study published last month said that space debris plummeting back to Earth could ...
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
The Hubble Space Telescope (HST) is one of the most well-known telescopes in the world and is responsible for iconic images of space featured in textbooks and publications around the globe.
The color of the glass is a pale bottle green, and the material is extremely vesicular with the size of the bubbles ranging to nearly the full thickness of the specimen." [ 3 ] The most common form of trinitite is green fragments of 1–3 cm thick, smooth on one side and rough on the other; this is the trinitite that cooled after landing still ...
