NASA team explores using LISA Pathfinder as 'comet crumb' detector
Apr 18, 2017 (SPX)
Most of these particles have masses measured in micrograms, similar to a small grain of sand. But with speeds greater than 22,000 mph (36,000 kph), even microme...
High-flying experiments demonstrate potential of balloon-borne infrasound detection
Apr 18, 2017 (SPX)
Infrasound, sometimes called low-frequency sound, is sound waves that occur at frequencies lower than the limit of human hearing. Infrasound signals can remain ...
