Week in Geek: Hubble Redux edition
The Atacama Large Millimeter/submillimeter Array (ALMA) just took the Hubble Ultra Deep Field to the next level.
ALMA is an array of 66 radio dish antennas located at an altitude of over 16.000 feet in the Atacama desert of northern Chile. Much like the Very Large Array (VLA) in New Mexico, these dishes all work in concert to create a telescope used to observe radio emission at millimeter and submillimeter wavelengths. Astronomers use radio telescopes to probe phenomena such as star formation by observing gas and dust clouds that are too distant and/or too faint to be see by infrared or optical telescopes.
Also features: tardigrades, lasers, blue jeans, and the Golden Record.
