"Two masers were in existence when this was written. It was necessary to build the second one so that it could check the first. No other instrument is accurate enough to test a maser.
During the tests the oscillation frequencies were compared with an accuracy of one part in 100 billion. Professor Townes states that this is probably the most accurate comparison or measurement of any two physical quantities that has ever yet been made."

With the ability to detect and amplify extremely weak electromagnetic signals without adding additional noise, masers have many potential uses, including the production of more sensitive magnetic resonance body scanners, such as those used in airports.
NGC 2170 – de Engelnevel
NGC 2170 is een reflectienevel die ongeveer 2700 lichtjaar van ons is verwijderd in de richting van het sterrenbeeld Monoceros – Eenhoorn. De nevel maakt deel uit van Monoceros R2, een van de meest nabije massieve stervormingsgebieden tot de Zon.
