Gamma-ray Burst, Very Briefly
Brighter Than Most Supernovae
By: Group 1
What can you see in
the picture?
Gamma-ray burst
In gamma-ray astronomy, gamma-ray
bursts are immensely energetic
explosions that have been observed in
distant galaxies.
Most energetic form of light.
Imagine that we
have a ring-side
view of a
spectacular
gamma-ray
burst(GRB).
GRBs are vey brief bursts of
powerful rays, lasting from a few
milliseconds to a few minutes,
during which they shine brighter
than most supernovae.
Astronomers suspect that GRBs are
associated with the violent death
of distant massive stars.
A GRB is characterized by a narrow jet of gamma
radiation that explodes from the collapsing star. The
beam of a powerful gamma ray photons is extremely
dangerous if it is oriented towards another celestial
object.
Scientist have learned much about those awesome
explosions. But they still have much more to learn about
them. Many questions about such _____ marvels a still
unresolved mysteries.
Lesson 9 is meant to be a mental expedition
intended to make you aware of the remarkable
things and events in outer space. Whenever you
think of them, you exclaim: “Awesome!” And you
cannot help but ask: “How did they come to be?...
Things like these do not just appear from nothing!...
Can someone explain to me this mystery?”
Let us end this lesson with the following
quotation from Albert Einstein, German-born
American physicist(1879-1955), Time’s “Person
of the Century” (20th century).
“We are in the position of a little child entering a huge library filled
with books in many different languages. The child knows someone
must have written those books. He does not know how. He does
not understand the languages in which they are written. The child
dimly suspects a mysterious order in the arrangement of the books
but doesn’t know what it is. That, it seems to me, is the attitude of
even the most intelligent human being toward God. We see a
universe marvelously arranged and obeying certain laws, but only
dimly understand these laws. Our limited minds cannot grasp the
mysterious force that moves the constellations.”
Thank You
