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.

Arecibo's huge primary dish, built into a sinkhole in a mountain range, has been used to discover the first exoplanets and detect organic molecules in a galaxy millions of light-years away. It's where the fictional astronomer Ellie Arroway got her start in the movie âContactâ and where real scientists Frank Drake, Jill Tarter and Carl Sagan, among others, launched efforts to detect extraterrestrial life.
