 
If you've ever broken a bone you know
that x-rays are bad for humans
and doctors make an X-ray picture a
broken bone
they leave the room to avoid being hit
by x-ray radiation every time
but the radiation you receive from an
x-ray have your arm
is 50 times less in the radiation where
blasted with
every year from cosmic sources
fortunately
our atmosphere block these extremes so
we're perfectly think here in turn
ok sum up the most powerful sources have
X-rays in the universe
are x-ray binaries these are made up
have a normal star like the SUN and an
ultra-compact a costar
call the neutron star or a black hole as
these two objects orbit one another
the neutron stars strong gravity post
material
of the campaign star and onto N a new
study
have an x-ray binary called Thursday Nov
x1
found that it is left in four thousand
six hundred years
old this makes it the youngest x-ray
binary
ever seen astronomers have detected
hundreds of x-ray binaries throughout
our galaxy
and other but these older x-ray binaries
only reveal information about what
happened much later in life if the
system
the new observations tell us new
information
about the stage just after the system
forms
