At this distance it is a relatively nearby spiral galaxy, and is part of the Antlia cluster -- a group of over 200 galaxies held together by gravity. This cluster is unusual; unlike most other galaxy clusters, it appears to have no dominant galaxy within it.

Upgrade to Mars rovers could aid discovery on more distant worlds Posted: 09 Sep 2013 12:30 PM PDT Mars rovers, such as Curiosity, currently can't make science decisions on their own. That has to change if future rover missions are to make discoveries further out in the solar system, scientists say.
