NGC 2442 |

Info |
NGC 2442 is located in the
southern constellation of Volans. NGC 2442 is
an unusual
barred spiral of around11th mag. It was discovered by Sir John Herschel
describing one of its spiral arms as hook-like.
NGC 2442
appears to have a less massive, distant companion that is also distorted,
and it appears likely the two have had an encounter in their recent past.
If there are no further meetings, the forces that hold NGC 2442
together will restore the galaxy to a more
symmetrical spiral form. But it appears more likely the companion
has been captured by the distorted spiral and will eventually be consumed
by it, triggering a dramatic bout of star formation. NGC 2442
is about 50 million light years distant. |

Notes/ Conditions |
Conditions- It has been rather a poor spring and start to
summer. This is really the first run I've been able to get in for around
two months. Conditions have been very cloudy.. |
