Our mission is to promote understanding of the natural world and our place in it.

The museum’s collections tell the history of the planet and are a record of human interaction with the environment and one another.

We steward a collection of 147 million specimens and artifacts. Each one reflects a moment in space and time; in these moments we find Earth’s story.

And our researchers continue to glean critical new information from these objects. These discoveries about the past help us model and anticipate the future.
