The Nova Corps.

The Nova corps are a universal peace keeping force, originally the militia of Xandar. Lead by Centurion Nova Prime, the corps was made up of 500 Xandarians before being destroyed by Zorr of the Luphomoids.

Following the restructuring of the surviving cities of Xandar, the Nova corps reformed and its members vowed to take a more active role in the universe. The surviving Xandarians used their Worldmind as their guide to explore and protect not only Xandar itself, but to see to threats in the rest of the Andromeda and Milky Way Galaxies.

The Nova corps have fought extensive battles against the Luphomoids, Skrulls and Dire Wraiths but despite great hardship and loss of Xandarian life, they have emerged victorious in every conflict.

Their base of operations is on Xandar in the star system Tranta in the Verge Galaxy.

The Nova Corps almost met it's end at the hand of the Annihilation Wave. When Annihilus and his forces attacked, the Worldmind recalled all active members, the corps fought valiantly to defend their world, yet in the end were defeated. The only member of the corps to survive was Centurain, Rich Rider. The Worldmind, which had also survived guided Richard to itself. In order to save the corps the Worldmind convinced Richard to allow it to  uploaded itself, and the entirety of the Nova Force into him, making him the Nova Prime. Richard went on to serve the Universe for a time as the only living Nova Centurion, even participating in events such as Ultron's attempted Conquest of the Kree, and defending the Knowhere base. Recently, other surviving Centurians have searched him out, and the future of the Nova Corps looks bright again.  

The Worldmind

The Xandarian Worldmind, also known as The Living Computer of all Xandar, is the primary source of knowledge and energy on Xandar. It makes all decisions regarding the use of the Nova corps and is made up of the accumulated intellect and knowledge of all deceased Xandarians.

Nova Force.

The Nova corps are imbued with the Nova Force by the Worldmind. This energy force provides powers like the ability of flight, super strength and a connection to the Worldmind itself. Those who are more experienced are able to tab into more powers like the ability to open stargates, energy blasts and the release of a brief electromagnetic static burst.
