Caption: Alessandro Falesiedi captured this detail in NGC 891, an edge-on galaxy about 13 arcminutes
across, by combining 440 minutes of imaging data taken with an 11-inch-aperture telescope.
M27 is of course somewhat larger (on the sky), about 8 arcminutes
long, whereas M76 is about 3 arcminutes

A prominent magnitude 9 yellow star (HD 20224) is situated about 4 arcminutes
to the north-east.
In 2008 the angular separation is closer to 42 arcminutes
, and it will be after 2060 before the separation is under 30 arcminutes
It's small (about 8 by 4 arcminutes
in extent) and presents a pallid face to small scopes.

By mid-April next year, they'll be only 8 arcminutes
apart as seen from Earth, and for a few days the Sun's interference will disrupt the ability of ground controllers to send the spacecraft any commands.

Although the galaxies are just 38 arcminutes
apart, they aren't twins.
