Molecular clouds are aggregations of rarefied gas (mainly hydrogen) from which stars can form. Often the impetus for star formation is an energetic shock wave from a nearby cosmic event such as a supernova. This compresses the gas along the shock front, causing it to clump. A situation of positive feedback can ensue, the clump becoming more massive, thus having a larger gravitational attraction (since gravity depends on mass). This increased attraction draws more material in, thus increasing the mass...

What is the Scale for universe molecular cloud galaxy star planet asteroid and atom biggest to smallest?
universe, molecular cloud, galaxy, star, planet, asteroid,atom
When a cloud fragment has compressed enough so that it glows?
The cloud fragment could be glowing due to a heavenly body which is behind it.
What is the birthplace of stars called?
Molecular cloud or Stellar Nursery .
If you wanted to observe a molecular cloud in what wavelength of light would you most likely observe?
infrared.
What is likely to happen to a molecular cloud core with a mass that is less than its Jeans Mass?
It will collapse.
The most common molecule in a molecular cloud is?
molecular hydrogen H2
Are supernova remnants found inside of open clusters?
Partly: The formation of an open cluster begins with the collapse of part of a giant molecular cloud (a dense cloud of gas containing thousands of times the mass of the Sun) Many factors could trigger the collapse of a giant molecular cloud (or part of it) and a burst of star formation which will result in an open cluster, including shock waves from a nearby supernova and gravitational interactions.
Is Solar nebula a star?
No, its a molecular cloud.
How do you remove the top nut on the rear shock of a 1997 Lincoln town car?
The rear shock spring will need to be compressed with a spring compressor. When the spring is compressed the top nut can easily be removed.
What does the gravitational force in a molecular cloud depends on?
Density

When a cloud fragment has compressed enough so that it glows?
The cloud fragment could be glowing due to a heavenly body which is behind it.
What is the most abundant material in a giant molecular cloud?
Hydrogen
What is the birthplace of stars called?
Molecular cloud or Stellar Nursery .
Can Novice replace the shock-sturt 1997 Cavalier?
A novice should not try to replace a shock strut. The strut spring needs to be compressed, in order to remove it. The compressed shock spring will be under several hundred pounds of pressure. This can create a very dangerous situation for the novice.
Can clouds be compressed?
Technically they can be as most of their volume is gaseous. However you compress a cloud it will warm adiabatically, and with enough heating from compression the cloud will evaporate.
What happens to the visible radiation produced by new stars within a molecular cloud?
It is absorbed by dust grains and heats up the cloud.
