Sand Art by Tony Plant
These amazing beach drawings may only be seen for a short period of time before the tide carries them away but Tony Plant has continued to create these ephemeral works of art for over 20 years. I’ve embedded a wonderful video below which shows his work in more detail.
‘The Atacama Large Millimeter/submillimeter Array, under construction. ALMA will be initially composed of 66 antennas, consisting a main array of fifty 12-meter antennas that can be spread over distances from 150 metres to 16 kilometers. In addition to the main array, ALMA will also have a compact array, composed of four 12-meter antennas plus twelve 7-meter antennas. By using the technique of interferometry, ALMA will work as a single giant telescope, enabling astronomers to observe the cold universe with unprecedented sensitivity and resolution.
