I do not know to choose either
machines to detect ghost
or
'shooting stars'
.Anyway,I have done some research on shooting stars .......Shoooting stars ..............
What causes a "shooting star"?
A "falling star" or a "shooting star" has nothing at all to do with a star! These amazing streaks of light you can sometimes see in the night sky are caused by tiny bits of dust and rock called
meteoroids
falling into the Earth's
atmosphere
and burning up. The short-lived trail of light the burning
meteoroid
produces is called a meteor. Meteors are commonly called falling stars or shooting stars. If any part of the meteoroid survives burning up and actually hits the Earth, that remaining bit is then called a
meteorite
.
At certain times of year, you are likely to see a great number of
meteors
in the night sky. These events are called meteor showers and they occur when the Earth passes through the trail of
debris
left by a
comet
as it
orbits
the Sun. These showers are given names based on the constellation present in the sky from which they appear to originate. For example, the Leonid Meteor Shower, or Leonids, appear to originate in the
constellation
Leo. It is important to understand that the meteoroids (and therefore the meteors) do not really originate from the constellations or any of the stars in the constellations, however. They just seem to come from that part of the sky because of the way the Earth encounters the
particles
moving in the path of the
comet's
orbit. Associating the shower name with the region of the sky they seem to come from just helps
astronomers
know where to look!
