History[ edit ] Hayden Planetarium, ensiklopedia astronomy —45 The center is an extensive reworking of the former Hayden Planetarium, whose first projector, dedicated inhad 2 successors previous to the current one. The original Hayden Planetarium was founded in with a donation by philanthropist Charles Ensiklopedia astronomy.


Its mission was to give the public "a more lively and sincere appreciation of the magnitude of the universe Chamberlainhired as an assistant curator inbecame Chairman of the Planetarium in In Januarythe original Hayden Planetarium was closed and demolished.

In Augusta new, customized Ensiklopedia astronomy Mark IX projector was installed, accompanied by a digital dome projection system that provides a 3-D visualization of the universe based on images generated in real time by a Silicon Graphics supercomputer.

Rose Center for Earth and Space

Polshek has referred to this work as a "cosmic cathedral". Also located in the facility is the Department of Astrophysicsthe newest academic research department in the Museum. This structure, a small companion piece to the Rose Center, offers a new entry way to the Museum, as well as opening further exhibition space for astronomically-related objects.

When the new Rose Center opened with a model of only eight planets, excluding Plutoensiklopedia astronomy had been thought of as the ninth planet, it resulted in a headline-making controversy.

It was established by the State of New York insome of the funding coming from philanthropist Charles Hayden. The Star Theater is one of the world's pre-eminent planetariumswhich incorporates high-resolution full-dome video to create "space shows", based in scientific visualization of current astrophysical data.

The Big Bang Theater serves as an introduction to the Heilbrun Cosmic Pathway, a spiral which wraps around the sphere, connecting the second and first floors of the Rose Center. The cosmic pathway provides a timeline of the universe's history from the Big Bang to the present day.

From the bottom of the Cosmic Pathway, visitors can stop by the Hall of Planet Earth to explore geology, weather, plate tectonics, and more, or go down to the Hall of the Universe to explore the realms of planets, stars, galaxies and ensiklopedia astronomy.

At eight landings, panels show visitors the relative size of the universe at that point in time, along with major developmental stages of the universe including the first generation of stars, globular clustersquasarselliptical galaxiesgalactic bulgesradio galaxiesthe Milky Way Galaxygalactic disksand later generations of stars.

At each of the landings, computer ensiklopedia astronomy provide overviews of the entire pathway, and more in-depth information, as well as connections to exhibit topics in the Hall of the Universe. Astronomical images appear at that time of the universe corresponding to that place on the pathway.

The light from these objects has taken billions of years to reach the earth, and visitors see them not as they are now, but as they were when their light began its journey toward Earth. Among these are some of the most distant celestial objects known to scientists, along with their cosmic " red shift ", the measurement that indicates what epoch of the expanding universe is being shown.
