Since intraplate earthquakes are not near plate boundaries, give a general idea of what you think might cause them. Do the largest earthquakes cause the most deaths and the most damage to property? California is famous for earthquakes along the San Andreas Fault zone but there is another type of plate boundary where large earthquakes occur.
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The pulses of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis.ike a black hole, it is an endpoint to stellar evolution.

T Tauri Star. [/caption] When a star is still in the earliest stages of formation, it doesnât have enough temperature in its core to ignite fusion of hydrogen and helium. Instead, the star shines with just the gravitational energy of its continue collapse. Astronomers call this pre-star a T Tauri star. This early stage lasts about 100 million years before nuclear fusion kicks in and it becomes a true star. As you might know, stars start out as vast clouds of cold molecular hydrogen.
