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.
You can think of this as the nebula-star-nebula cycle. Stars that evolve into red giants can lose their outer layers during pulsations in their outer layers, known as their atmospheres. This released matter is typically 97% hydrogen and 3% helium, with a few other trace materials.o, it is this dispersed matter that eventually collapses and forms a nebula. Nebulae, like the Orion Nebula, are often favorite astronomical objects of scientists who want to learn more about stellar or planetary formation.
