The Sound of Outer Space Comes from Saturn


Saturn, a beautiful ringed orb hanging in the darkness of space. That's how you see it in a telescope. It speaks to you of mysteries in space. Have you ever wondered what Saturn would sound like if you can hear it? The Cassini spacecraft, which was sent to this wonderful ringed planet, has captured its radio emissions from energetic auroras which has been compressed and translated by the National Aeronautics and Space Administration (NASA) into sounds that we can hear and appreciate.

If you've ever wondered what space sounds like, then you can listen to the voice of Saturn. There are many other "voices" out there coming in from different levels of the electromagnetic spectrum, but Saturn's is one for the books because its sounds really does remind us of the vastness immensity of space. Note that 73 seconds of playback of the sounds of Saturn is really equivalent to 27 minutes in real time. The frequency had also been lowered to a range audible to the human ear.

SkyXplore Begins SpaceDome Mobile Digital Planetarium Project in the Philippines


The Diliman Preparatory School in Quezon City in the Philippines has launched its SkyXplore project with the SpaceDome Mobile Digital Planetarium as the main attraction. The astronomy education program is headed by former Philippine Senator Nikki Coseteng and aims to bring astronomy closer to the Filipino student through the inflatable planetarium, creating new windows for education and opening doors to new careers in science and technology. As of this writing, only the Rizal Technological University offers degree courses in astronomy.

The planetarium will be taken to schools nationwide to promote astronomy and to educate students in the science. She will be aided by astronomy consultants like Frederick Gabriana and wife Rochelle (2nd picture from the top). Lecturers include Ramon Acevedo, resident astronomer of the Seven Suites Observatory Hotel in Antipolo City. The planetarium currently shows the sky as seen by different cultures (like the Inuit and Lakota) with the Western view taking precedence.

Astronomer Gabriana will soon by integrating Philippine constellations in the open source program used with the planetarium computer and projector. He will be using the research of Historian Dr. Dante Ambrosio of the University of the Philippines. It will be the first time that the sky as seen by indigenous peoples of the Philippines will be featured in a planetarium program. Aside from stars, planets, and constellations, the planetarium is also capable of taking the viewer on a travel through time and space. It's also for showing movies. Shown at left is Coseteng presenting the meteorite collection of the Gabrianas which was originally part of the Allen Yu space rock collection.
