THE HELLS IN THE HEAVEN (Part-1) - MAGNETARS
In the beginning, there was nothing but, darkness and then from a violent explosion, the whole story of space and time begun.
This phenomenon in the history of our universe is known as
the “Big bang”. This enormous explosion occurred 13.8 billion years ago and
with this everything we see around us including space and time itself begun.
Our universe seems so beautiful because of the illuminating
stars and different colors that we often see in the pictures taken by different
telescopic satellites and therefore we call our outer space as “HEAVENS”.
But, in reality, the heaven is full of hells.
Yes, there are dangerous places spread all around out there
and it is quite obvious as the destruction is the mother of all creation and no
matter how beautiful our universe is but, it started with an explosion.
There are regions in our universe , not few but many in
numbers , where high unstable energy interactions are going on and these interactions are far
more powerful than any kind of nuclear explosions ; In fact, nuclear explosions
and not qualified enough to be compared with such kind of interactions.
Let us discuss these most violent places of our universe one
by one.
MAGNETARS
When a star much bigger than our sun (30 to 40 times in mass) ran out of their nuclear fuel then they started dying by the force of their own gravity which compresses the star and finally it explodes with a violent explosion know as “The super-nova explosion”
Normally, stars with such high mass must form a black hole
but, there are certain star that typically losses some amount of mass right
before the super-nova explosion.
Hence,
instead of forming a black hole they ended up in forming a “Neutron star”. This
neutron star is the remnant of the original dead star which is now shrunk to a
size of a state (, i.e., much less than the size of a moon) but, the density of this
star is so heavy that a teaspoon matter
of a neutron star is equal to the weight of the entire population of the earth.

Sometimes neutron stars are formed with extremely high
magnetic field strengths and these types of neutron stars is called as “MAGNETARS”.
How powerful a Magnetar is?
The magnetic field strength of a Magnetar is about 1000
trillion times than that of our earth. This immense power of a Magnetar can
take out all the iron atoms from your body at a distance of about 100 thousand
miles away which is half of the distance between the earth and moon.
These mischievous stars have the strongest magnetic field in
the universe and till now, scientist has discovered 12 of them in our own
galaxy and there may be more of them in our own galaxy.
Quakes in Magnetar
When the magnetic power of a Magnetar gets incredibly strong
then, it deforms the crust of the star and results a “STAR-QUAKE”.
With the advent of a star quake; two high energy beams
shoots outside from the two poles of the star.
The energy beams are so powerful that it outshines all the
other stars in the galaxy for a few seconds. These high energy beams are the
gamma rays moving at the speed of light and hence it is called as a “gamma ray
bursts”.

On 27th December 2004; satellites picked up the
greatest explosion ever recorded and this was from a Magnetar present 30,000
light years away from us performing a gamma ray bursts.
