EYE ON THE SKY SEPTEMBER 09

W Galactic
double ring

VERY LARGE
TELESCOPE,
24 JULY 2017
Galaxy NGC 7098
is an unusual-looking
spiral galaxy, in
that its arms form
two distinct rings.
As well as this, the
galaxy has
developed two
ansae, which are the
bright areas of stellar
density seen at the
top and bottom of
the central region.
These can be found
at either end of the
central bar in some
galaxies, although
their exact origin is
not known for sure.
Saturn’s hazy
horizon X

CASSINI SPACECRAFT,
16 JULY 2017
Haze on the limb of
Saturn gives a view of
the atmosphere into
which the Cassini
spacecraft will plunge
when it ends its mission
on 15 September 2017.
This image captured by
Cassini also shows Saturn’s
rings rising above the
planet’s horizon. The
spacecraft is likely to
lose contact with Earth
before it reaches the
depths of the haze.
