Outer space, or just space, is the void that exists between celestial bodies, including the Earth. It is not completely empty, but consists of a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust …

Argon is a chemical element with syol Ar and atomic nuer 18.It is in group 18 of the periodic table and is a noble gas. Argon is the third most abundant gas in the Earth''s atmosphere, at 0.934% (9340 ppmv).It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as

Methane (US: / ˈ m ɛ θ eɪ n / or UK: / ˈ m iː θ eɪ n /) is a chemical compound with the chemical formula CH 4 (one atom of carbon and four atoms of hydrogen).It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas.The relative
Ethanol is an important industrial ingredient. It has widespread use as a precursor for other organic compounds such as ethyl halides, ethyl esters, diethyl ether, acetic acid, and ethyl amines. Solvent Ethanol is miscible with water and is a good general purpose solvent..
The interface between the Earth''s surface and outer space. The Kármán line at an altitude of 100 km (62 mi) is shown. The layers of the atmosphere are drawn to scale, whereas objects within them, such as the International Space Station, are not.Outer space, or simply space, is the expanse that exists beyond the Earth and between celestial bodies.

It was then that a group of paleontologists working in Italy obtained some very puzzling data at a site near Gubbio. The chemical analysis of a layer of clay deposited above sediments formed during the Cretaceous period (and therefore a layer that records events occurring after the Cretaceous period)
The earliest life on Earth existed more than 3.5 billion years ago, during the Eoarchean Era when sufficient crust had solidified following the molten Hadean Eon. The earliest physical evidence so far found consists of microfossils in the Nuvvuagittuq Greenstone Belt of Northern Quebec, in "banded iron formation" rocks at least 3.77 billion and possibly 4.28 billion years old.

Definitions The definition of life has long been a challenge for scientists and philosophers, with many varied definitions put forward.    This is partially because life is a process, not a substance.    This is complied by a lack of knowledge of the characteristics of living entities, if any, that may have developed outside of Earth.
Acetonitrile is the chemical compound with the formula CH3CN. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purifiion of butadiene. In the laboratory, it is
It was then that a group of paleontologists working in Italy obtained some very puzzling data at a site near Gubbio. The chemical analysis of a layer of clay deposited above sediments formed during the Cretaceous period (and therefore a layer that records events occurring after the Cretaceous period) showed a surprisingly high content of the element iridium (Ir).
