Isaac Newton 2.5-m Telescope
Explanation:
It shines with the brightness of 100 billion Suns.
Is it a mirage? The recently discovered
quasar labeled
APM 08279+5255 has set a new record
as being the brightest continuously emitting object yet known.
APM 08279+5255's great distance, though, makes it
only appear as bright as magnitude 15.2,
an object which can be seen with a moderate sized telescope.
It is the quasar's extreme
redshift of 3.87 that places it far across our universe,
and implies a truly impressive energy output.
One possible explanation of APM 08279+5255's
record luminosity is that it is partly a mirage:
its light is highly magnified by an intervening
galaxy that acts as a
gravitational lens. Alternatively,
APM 08279+5255 might be the most active known center
of an intriguing class of
colliding galaxies rich in gas and
dust.
