we have booster ignition and liftoff of
Columbia reaching new heights with it
the main thing Chandra does is take
these superb sharp
ordinary matter or the stuff we and
everything around us is made of consists
largely of empty space
this is because matter is made of atoms
and atoms a cloud of electrons orbiting
around nucleus composed of protons and
neutrons suppose we could generate a
force strong enough to crush all the
emptiness out of a stone roughly the
size of a football stating the stone
would be squeezed down to the size of a
grain of sand and with still wait four
million tons
now imagine something that dense that is
not the size of a grain of sand but
rather the size of the island of
Manhattan that's a neutron star or the
most exotic objects in the universe
slavko bogdana of Harvard University
explains the neutron stars are born
neutron stars are created when a massive
star runs out of fuel and collapses as
the star collapses the density become so
immense that protons and electrons are
squeezed together tightly to form
neutrons the end result is a star only
20 kilometers across but weighing one
and a half times more than our Sun and
made up mostly of neutrons these exotic
objects possess enormous gravitational
fields about 100 million times stronger
than what we experienced on earth and
have very strong magnetic fields
once a neutron stars formed however it
does not mean it just sits quietly in
the cosmos rather neutron stars have
been found to do some incredibly
interesting things that astronomers are
still trying to understand
neutron stars are the most rapidly
rotating stars we know about with the
fastest spinning at an incredible rate
of over 700 times per second for many
neutron stars the strong magnetic field
and fast rotation create a giant
electric generator which burns with
deadly beam of high-energy particles as
the neutron star rotates the radiation
from the particles appears to false
analogous to rotating like I've seen
such a neutron star is called the bolts
on the wind of fast-moving particles
generating that ball sir can also
produce a large glowing clouds
surrounding a star called a pulsar wind
nebula most of the radiation from
pulsers is observed at x-ray energies
Chandra is a valuable tool in the study
of these intriguing objects
so while some neutron stars are these
stellar whirling dervishes other
intriguing in other ways for example
through the class of neutron stars
called magnet ours that had magnetic
fields that are about a quadrillion
times the earth that's a one followed by
1500 for those keeping track
dr. McDonough explains what these
intense magnetic fields can do to a star
immense magnetic field of a magnetar
exerts enormous strain on the present
roster on rare occasions the strong
magnetic forces can break apart the
crust resulting in a powerful starquake
similar to call fuel within the earth
the Starks are among the most violent
events in the universe and release
tremendous amount of energy much written
in the form of x-ray radiation by
catching one of these outbursts in the
act following his behavior over time
with x-ray telescopes which is Chandra
we can learn a great deal about the
extreme conditions at the surface of
these exotic stars
clearly neutron stars are unlike
anything we know about here on earth and
because they are so extreme they give
scientists a chance to test their ideas
about matter in a way that just can't
happen in a laboratory
no matter what flavor in the neutron
star each one is a chance to learn about
the fundamental laws of physics that
rule our universe for more information

history but the only person around it
doesn't have TV coverage to the face and
then they got the black up now you're
gonna be getting a TV picture never fail
us we are getting
a picture with him out
quantity
ok
