How are planetary nebula formed? How are gas planets created? How many planetary systems are there? How does the transit method for detecting extrasolar planets work? How are asteroids formed in space? Where are rocky asteroids found in the solar system?
An understanding of how Earth's oceans were formed must begin with an examination of how our solar system developed. Scientists believe our solar system began forming as a huge cloud of dust that collapsed to form a sun surrounded by a flat disk of particles rotating around it, This disk-th...
DThe region with the greatest concentration was formed when the protosun exerted a gravitational pull on the other parts of the nebula. 5 An entirely different model is now thought to describe the most likely series of events that led to our present solar system. The central idea of this mo...
The protostar is basically a baby star, and grows into a star through its life cycle in the same way as we are born and grow.The main process of all stars' birth is called Nuclear Fusion. Nuclear Fusion happens in very large clouds on gas called nebula. When nuclear fusion starts in ...

Topics include how stars are formed within the Orion Nebula, a three-dimensional (3D) diagram showing a region within M42 near the Trapezium star cluster, labeled Orion-South, and an overview of Orion's structure, including an area called the Photon Dominated Region (PDR).O'Deii...
Learn what the solar nebula theory is. Understand how the nebular hypothesis explains the formation of the solar system, expanding on the evolutionary hypothesis. Related to this Question Describe how a star forms and the six different stages of a star's life. ...
Developing improved telescopes, Huygens was able to make several important astronomical discoveries. It was in 1655 that he proposed that a thin, flat ring circled Saturn. His discovery of Titan marked the first moon spotted around the planet. He made the first known drawing of theOrion Nebula....
