Mystery Object Explained
Explorers often discover the
unexpected.
Such was the case when the
Second Palomar Observatory Sky Survey
chanced upon the unusual object circled in the
above photograph.
The so-called
mystery object appeared star-like but
displayed colors unlike most stars or quasars.
Further investigation has now revealed the object to be a
Broad Absorption Line (BAL) quasar,
a relatively rare type of
active center of a distant galaxy.
Different atoms and molecules in the absorbing gas
surrounding the
BAL quasar's center probably cause the unusual colors.
We are fortunate enough to live in the fascinating age
when much of the
universe is
being investigated for the first time,
so exciting - and often unexpected -
discoveries are sure to continue.
