In celebration of The Hubble Space Telescope's 25th Anniversary, a special light and sound installation created by German artist and composer Tim Otto Roth will be on view in the American Visionary Arts Museum's Jim Rouse Visionary Center plaza. The installation, titled Heaven's Carousel, links together the fields of art, music and astronomy. Conceptualized and designed by Roth, the work is inspired by novel work on the accelerating expansion of the Universe by Nobel laureate Adam Riess (Space Telescope Science Institute), Greek cosmology and Renaissance astronomers. This special temporary exhibition will be on view from April 24 thru May 2, 2015, and is part of The Hubble Space Telescope's 25th Anniversary Public Events. Visitors are invited to join us in gazing skyward at this remarkable installation, and ponder the mysteries of our expanding universe which the revolutionary Hubble Space Telescope and NASA scientists have begun to unravel. While on our wonderland campus, marvel at Andrew Logan's mirrored mosaic Cosmic Galaxy Egg, which features Hubble images of birthing new stars and dying galaxies, and Steve Heller's illuminating Stargate, created with recycled metal and antique auto parts.
Light and the Electromagnetic Spectrum
- What is light and how do telescopes detect it? It’s all here in “Light, color, and optics.”
- Dividing light into its rainbow of colors is a useful tool used by astronomers. Find out how in “About Spectroscopy.”
The Doppler Effect in Astronomy
- Learn how Hubble measures the speed of colliding gas in “STIS Reveals Invisible High-Speed Collision Around Supernova 1987a.”
- Read how Hubble provided evidence for the existence of black holes in “Hubble Confirms Existence of Massive Black Hole at Heart of Active Galaxy.”
- Extrasolar planets are hard to find. “Hunting for Planets” explains some clever planet-hunting techniques, including the Doppler-based “radial velocity” method.
The Expanding Universe
- Edwin Hubble shows that the Milky Way is just one of many island universes in “Piercing the Sky.”
- See how the expanding universe stretches light from distant objects in this animation called “Cosmological Redshift.”
- How big and how old is our universe? “Building a Ladder to the Stars: The 90-year Quest for the Size of Our Universe” presents a timeline of how astronomers tried to nail down the measurement that would answer those questions.
- The interactive story "Dark Energy: An Accelerating Universe” tells the quest to identify this mysterious form of energy.
- Astronomers constrain the nature of dark energy in “Refined Hubble Constant Narrows Possible Explanations for Dark Energy.”
- Hubble shows that dark energy has been around for a long time in “Hubble Finds Evidence for Dark Energy in the Young Universe.”
