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.
Planetary nebulae are shells of gas thrown out by some stars near the end of their lives. Our Sun will probably produce a planetary nebula in about 5 thousand million years. They have nothing at all to do with planets; the terminology was invented because they often look a little like planets in small telescopes.he gas and dust in the nebula emits light because it is irradiated by nearby emerging stars. Located at a distance of about 1,600 light years, the Orion nebula is the brightest diffuse nebula in the sky, visible to the naked eye.
