A galaxy is a large group of stars that orbit around a common point usually a Supermassive Black Hole. Some galaxies, such as the dwarf Galaxy called Segue 2, do not have a Supermassive Black Hole but rather orbit a central gravitational point. The word galaxy comes from the French ...
A planetary nebula is a phenomenon that occurs when a small to medium star approaches the end of its life cycle. The first one was...
According to the author, the two objects span the same size--half a degree--from Earth. The Pleiades star cluster, the Andromeda Galaxy, and the vast Eta Carinae Nebula are all larger than the Moon. The Ring Nebula and the Tadpole Galaxy are both smaller than the Moon. Several diagrams ...
A planetary nebula may only exist for 20,000 years or thereabouts as the nebula breaks down and dissipates amongst the stars leaving the white dwarf on its own. Those white dwarfs in space would have been a planetary nebula at one time. In agalaxyof over 250 billion stars, there are onl...

What is the distinction between a nebula and a galaxy? Why is bigger better for astronomical telescopes? Name the most recent modification of the standard Big Bang model, and briefly explain how it differs from the standard model. Why do you think it took so long for astronomers to accu...
How far away is spiral planetary nebula? How much smaller is Venus than the sun? What is the distance from Earth to the moon in miles? How far away is the constellation Orion? How far away is Arcturus? What is the distance between the Earth and the nearest star?
that was fused from the sun's original hydrogen supply will also be exhausted, and all fusion will cease. The star will eject its outer layers, creating a glowing cloud called a planetary nebula.In the center of this nebula, the remaining core of the sun will contract into a white dwarf...
Anannular solar eclipseoccurs when the moon passes between the sun and Earth when it is near its farthest point from Earth. At this distance, the moon appears smaller than the sun and doesn't cover the entire face of the sun. Instead, a ring of light is created around the moon. ...
