It’s Earth Hour for 8 Billion Angels

   Saturday March 28th is the annual Earth Hour celebration. Started in 2007 the Earth Hour celebration is a world-wide citizen-powered effort to call attention to our planet’s environment and the need to better take care of our home (our only home).
   Earth Hour, although one hour, is an ongoing effort to encourage taking action about climate change as well as the destruction of nature and decreases in biodiversity.
   So on Saturday evening March 28th, at 8:30 pm (your local time), turn the electrically powered lights off in your house for one hour. But don’t stop there. Act locally and think globally! Get involved – stay involved.
   With lights out this may be a good time to step outside, weather permitting, and take a look at what could possibly be darker night skies with lights off in your neighborhood. That’s the 4.5-day old waxing crescent Moon near the inner planet Venus. And Venus is just a few days away from passing across the open star cluster, the Pleiades.

   From the Earth Hour web site:

This year, we are facing Earth Hour in exceptional circumstances with countries around the world experiencing a health crisis with the outbreak of the novel Coronavirus (COVID-19). In light of the latest developments, the Earth Hour global organizing team is recommending all individuals to take part in Earth Hour digitally this year.

   The Best of the Earth Observatory
   Choose the best among 32 pictures of Earth as seen by the many Earth-orbiting satellites. If you are not familiar with the Earth Observatory web site it is an incredible resource of images of our home planet.

   That’s us, and we have a home that is danger from not only climate change, the destruction of nature, and decreases in biodiversity, but our only home is also loosing to the demands of an increasing population and its effect on the local environment. At the 8 Billion Angels web site there is information about the effect a growing population is having on our planet. Be sure to watch the video trailer and perhaps consider organizing a community viewing.

It’s Our Home

   “It’s our home, our only home” is a quote I came across and copied into my collection. It is from a video I used in my classroom many years ago. Can’t remember the video name nor find it but nonetheless it makes a powerful statement about our home planet. So this posting is in the spirit of celebrating our home planet.
   Monday the 22nd is Earth Day, an annual event sponsored by individuals, groups, and organizations who are activists (this is a positive use of the word), or stewards striving to create a more healthy environment for all. This is accomplished through education as well as events such as Earth Day.
group-large   Two years ago I joined with a group of musicians to form Dark Matter, a group of educators, scientists, musicians, and artists with the initial purpose of producing a series of Astronomically-based videos that would accompany a live musical performance. The videos were originally developed for use in the full dome video system at the Gottleib Planetarium at Union Station in Kansas City. The dome was approximately 60 feet in diameter and could seat around 150. The original videos were warped to suit the projection system however the two below are flat screen versions of the videos.
   The performance was called Orbit and with that as a theme I developed the videos with the compositions the composers provided. The style of music is described as electro-acoustical and was a combination of live combined with digitized sound samples and real-time sound sampling as the musicians played. The videos below were the opening and closing compositions and both were called Water Meditation. In the first piece the flute is played by Rebecca Ashe, and the second piece has a clarinet played by Cheryl Melfi. Music is composed by Daniel Eichenbaum and Richard Johnson with Richard also doing the real-time sampling during the performance.

The Banner graphic is from a high altitude balloon launched as part of the production for another full dome video and live performance called Ascent. This was during the fall of 2011 and is a view from 95,000 feet of the two neighboring cities of Kansas City Missouri and Kansas Kansas City Kansas.

   Water Meditation – Flute by Richard Johnson: Earth is a water world with more than 70% of its surface covered with water. Gain a different perspective of the planet as you orbit the Earth with a satellite. Flute is played by Rebecca Ashe.

   Water Meditation – Clarinet by Daniel Eichenbaum: As the closing composition I wanted to leave the audience with a sense of what it would be like to orbit the Earth with the International Space Station. So from that perspective we see a sunrise from orbit and our home planet as the rising Sun brightens the daylight side of the Earth. Clarinet is played by Cheryl Melfi.
