|A symphony of planet-wide observations began abruptly
on March 28 when the Earth-orbiting
detected a burst of high-frequency
gamma-rays from GRB 110328A.
When the same source
flared again after a
45 minute pause
it was clear this event was not a typical
the initial fanfare astronomers using the 2.5-meter
Telescope chimed in with a mid-range observation of
the optical counterpart.
the explosion was picked up in baritone low-frequencies of radio waves
ELVA radio dishes in the USA.
Later many optical telescopes, including the 8-meter
Gemini North telescope in Hawaii,
began playing along by tracking the optical counterpart.
The unusual source was spotted at a higher register in
X-rays by the
X-ray Observatory and was intermittently
in the even more soprano-like gamma-ray range for a week.
Joining the chorus,
Hubble Space Telescope recorded

If associated with the galaxy, this explosion occurred when the universe was
two thirds of its present age.
There is much speculation that the unusual gamma-ray burst
was a star being ripped apart by a supermassive
in the center of a galaxy and the
puzzling features of the
distant detonation are still being explored.
