The Missouri Department of Conservation (MDC) administers hundreds of parcels of land in all counties of the state. Most areas are owned by the department; some are leased by the department; some areas are managed under contract by the department; and some areas are leased to other entities for management.
The following are approximate tallies of current listings by county. These counts are based on entries in the National Register Information Database as of March 13, 2009 [2] and new weekly listings posted since then on the National Register of Historic Places web site. [3]
NGC 6522 is possibly the oldest star cluster in the Milky Way, [10] with an age of more than 12 billion years. [11] [12] It is a core collapsed cluster with a core radius of 0.5′ and a 1.0′ half-light radius. [9] The cluster formed four billion years before the Milky Way galactic bar appeared, and may have been confined to the bar for a ...
This is a list of Superfund sites in Missouri designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

For core masses of 40–60 M ☉, the collapse halts and the star remains intact, but collapse will occur again when a larger core has formed. For cores of around 60–130 M ☉ , the fusion of oxygen and heavier elements is so energetic that the entire star is disrupted, causing a supernova.
The OMB defines a core-based statistical area (commonly referred to as a CBSA) as the county or counties (or county-equivalents) surrounding at least one densely-settled core of at least 10,000 population, [2] "plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with ...

Core collapse can refer to: The collapse of the stellar core of a massive star, such as the core collapse that produces a supernova Core collapse (cluster) , the dynamic process that leads to a concentration of stars at the core of a globular cluster
