A
long
time
ago
in
a
galaxy
far
far
away,
there
was
a
large
and
magnificently
brilliant
star
that
shone
across
the
young
expanding
universe.
The
light
from
that
blue
star
travelled
through
space
for
billions
of
years,
and
then
one
day
a
few
thin
beams
crashed
into
a
polished
mirror—the
light
bucket
of
the
Hubble
Space
Telescope.
In
a
report
published
Wednesday
in
the
journal
Nature,
a
team
of
astronomers
asserts
that
this
is
the
most
distant
individual
star
ever
seen. They
describe
it
as
50
to
100
times
more
massive
than
our
sun,
and
roughly
1
million
times
brighter,
with
its
starlight
having
travelled
12. 9
billion
years
to
reach
the
telescope.
The
lead
author
on
the
report,
Brian
Welch,
gave
the
star
a
name:
Earendel,
meaning
“morning
stars” .
“Earendel
was
found
in
a
young
galaxy
known
as
the
Sunrise
Arc,
and
‘morning
stars’
seemed
appropriate,”
Welch
said.
“This
is
one
of
the
major
discoveries
of
the
Hubble
Space
Telescope
in
its
32
years
of
observation,
”
said
Rogier
Windhorst,
a
co-author
of
the
report.
In
recent
decades,
astronomers
have
seen
galaxies
at
that
distance,
and
even
farther
away,
but
galaxies
are
collections
of
billions
of
stars
and
the
very
distant
ones
have
typically
been
nothing
more
than
smudges
of
light.
Despite
its
mass
and
brilliance,
Earendels
discovery
would
not
have
been
possible
were
it
not
for
the
cosmic
alignment.
Between
Hubble
and
the
star
lies
a
galaxy
cluster,
WHL0137-08,which
is
so
huge
tha
