Asteroid Discovery 1980-2010

Vodpod videos no longer available.

This animation by the National Astronomy and Ionosphere Center shows a beautiful view of the past 30 years of asteroid discoveries, using dataculled by Ted Bowell et al.

As time passes, asteroids are highlighted white and then colored by how closely they come to our inner solar system. Earth crossers are red, Earth approachers are yellow, and all others are colored green.

What you get is a view of the solar system’s planets and asteroids orbiting the sun and these beautiful sparkles in sky. As automated sky scanning systems come online in the 1990s, we see waves of discoveries. Then starting at the beginning of 2010, we see a discovery pattern as a result of the Wide-field Infrared Survey Explorer, which has been tasked with mapping all infrared light in the sky.

Harvest (2009) For Terrafon, Traditional Music Ensemble and Cropland

Harvest by Alunda Kyrkokör (2009) On Vimeo

In this performance Alunda Church Choir, conducted by Cantor Jan Hällgren, plays the soil of northern Uppland (in Sweden). Harvest by Alunda Kyrkokör was exhibited at the Volt Festival in Uppsala the 6th of June 2009. Terrafon is large agricultural version of the horn gramophone, amplifying the sounds in the track it ploughs.

There is more to come. There are still many croplands still untouched by terrafon. The only thing needed is a powerful local musical ensemble that can sweat it out. This is indeed a demanding piece.

The idea is to record new performances – with new ensembles and local cropland – when we show the piece in the future.
