Would you please tell me what is in there ? I mean what substances are existing ? Where can i find out some information about this ?
Thank you very much,
Thank you very much,
That is what i would like to know, and from what you explained, that means there is only hydrogens and no other atoms ?is mostly empty space (no atmosphere at all) except for a few atoms of hydrogen scattered about.

If there is any object flying in space, there will be no friction s or if any, they will be very small, right ?
meteor said:In the galaxy, the hydrogen sometimes groups in certain "clouds", 3 of the most notorious are the following
-HI regions: They are clouds of neutral hydrogen,the hydrogen is in form of atoms
-HII regions: Also known as emission nebulae. Composed of ionized hydrogen. For example the Pelican nebula

-Molecular clouds: Hydrogen forming molecules
Oh well, it is very nice of you to do that for me...I read all of what you tried to explain, Thanks alot,Originally posted by Phobos
No problem - - We like explaining this stuff.
The atmosphere in our galaxy is primarily made up of hydrogen and helium, with smaller amounts of other elements such as oxygen, carbon, and nitrogen. These elements are constantly swirling and moving throughout the galaxy, creating a dynamic and ever-changing atmosphere.
The atmosphere in our galaxy plays a crucial role in sustaining life on Earth. It protects us from harmful radiation, regulates our planet's temperature, and provides us with essential elements such as oxygen for breathing and carbon for photosynthesis.
The composition and structure of atmospheres can vary greatly between different galaxies. Some may have thicker or thinner atmospheres, different ratios of elements, or even no atmosphere at all. The atmosphere in our galaxy is unique to our specific environment and history.
Cosmic events such as supernovas, black holes, and solar flares can have a significant impact on the atmosphere in our galaxy. These events can release large amounts of energy and particles into the atmosphere, causing changes in its composition and creating new elements.
Scientists are constantly studying the atmosphere in our galaxy to better understand its composition, structure, and role in the universe. Current research efforts include using advanced telescopes and satellites to gather data, conducting experiments in space, and developing models to simulate and predict atmospheric changes.
