Sentences with phrase «ionized hydrogen atoms»

As our solar system slowly orbits around the galactic center, the sun's ultraviolet radiation carves out an egg - shaped region of ionized hydrogen atoms surrounded by neutral hydrogen gas.

The holes in the cheese represent places around stars and galaxies where UV radiation has ionized hydrogen atoms, bringing 21 - centimeter emissions to a halt.

Ionized hydrogen atoms could then easily combine with oxygen, forming our H2O ice.

An ionized hydrogen atom, consisting of a proton shorn of its associated electron, can not undergo the 21 - centimeter transition discussed above, since that transition depends on the relative spins of the electron - proton pair.

Charged particles striking Saturn's upper atmosphere ionize hydrogen atoms and produce infrared radiation, whereas related processes also give off Saturnian auroras at ultraviolet and radio wavelengths.

Not exact matches

Due to the high temperatures and intense radiation present, these atoms initially existed in an «ionized» state: The negatively charged electrons had been stripped from positively charged protons, leaving behind positive hydrogen ions (essentially, just protons).

If high - energy particles from deep space, called cosmic rays, happened to hit one of those hydrogen atoms, it became ionized, stripped of its electron.

Eventually, the majority of the hydrogen atoms in the universe became ionized.

During a stage of high temperature right after the Universe's birth about 14 billion years ago, the hydrogen atom was ionized, i.e., split into a nucleon and electron.

As the starshine intensified, it eventually stripped electrons from the hydrogens, ionizing the atoms.

However, almost every hydrogen atom in the IGM, out to the farthest galaxies telescopes can see (13 billion light - years away), has been ionized — has lost its electron.

The ionized hydrogen, with atoms violently stripped of their electrons, seems to fill the interior of the superbubble while the neutral hydrogen forms its walls and cap.

As a result, once water molecules are dissociated into ionized hydrogen and oxygen atoms by the Sun's ultraviolet light in Venus» upper atomsphere, they are more easily blown into space by the Solar wind (S.I. Rasool, 1968).

«We saw number of spectral features emitted by ionized atoms in the galaxies such as hydrogen, oxygen, and neon, which allowed us to determine the metal content of the galaxies.»

Diffuse emission nebulae are often called H II regions because they are mainly consisted of ionized hydrogen, H II - the roman number after the element symbol (here H) designating the ionization level: «I» would stand for neutral atoms, the «II» here means first ionization, i.e. the hydrogen atoms have lost their single electron, and for other elements higher numbers (ionization levels, or numbers of lost electrons) would be possible (e.g., He III, O III or Fe V).
