Usually, if the initial fetal heart rate and contraction pattern show that both mom and baby are doing well, the monitor is removed and used intermittently. If there are no indications for continuous fetal monitoring, it is OK to ask the nurse to remove the monitor to allow you to walk.
A star forms a nebula when it runs out of fuel. The star either  becomes a red giant or a supergiant, then the star would be blown  off into space either by expansion or expâ¦losion. The outer layers,  which was released into space, would become a nebula, or sometimes  a part of a larger nebula.
The word nebula is Latin for mist or cloud and the term planetary nebula is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects appeared to him to resemble the rounded shapes of planets. mechanism for formation of most planetary nebulae is thought to be the following: at the end of the star's life, during the red giant phase, the outer layers of the star are expelled by strong stellar winds.
