My
Hero:
MAARTEN SCHMIDT

I have chosen Maarten Schmidt
As my Science Hero, Who really
Just named Quasars 'Quasars'
Now moving on to Quasars, Quasars
Are
quite possibly the most destructive force in the universe. A quasar (contraction
of Quasi-stellar radio source) is an extremely powerful and distant active
galactic nucleus. Quasars were first identified as being high redshift
sources of electromagnetic energy, including radio waves and visible light,
that were point-like, similar to stars, rather than extended sources similar
to galaxies. While there was initially some controversy over the nature
of these objects, there is now a scientific consensus that a quasar is
a compact region 10-10,000 Schwarzschild radii across surrounding the
central supermassive black hole of a galaxy. Quasars are very bright the
furthest away one is 2.44 giga light years away. Sometimes quasars are
formed when a gas rich galaxy collides with a giant galaxy.
Now
I feel that quasars help us discover more about the universe, about the
laws of physics and chemistry, and give us an insight as to what it would
be like when the big bang went off, it also gives us a glimpse of what
the future has in store for us
