The expansion will add a 55 foot digital planetarium, a 4-d multi sensory theater and an outdoor telescope viewing terrace.
The collection of handcrafted telescopes will give guests and students across the state a chance to view close up images of space in person, in the classroom and in the planetarium.
A museum spokesperson says teachers across the state will be able to request where the telescope is pointed and with a small camera, students will see detailed images from the solar system.
The renovations are expected to be finished in early 2014.
The museum expects to attract more than 200,000 people from young children to adults once the new attractions open.
