The single whistler event was recorded over a crustal magnetic field, at an altitude of 349 kilometers (217 miles) on the night side of Mars. This last part is crucial: When under the direct glare of ...

Abstract: High-resolution lunar imaging using Earth-based radar is essential for advancing lunar science and exploration. Stepped-frequency waveforms have emerged as an effective approach to achieve ...

A new study finds that horse whinnies are made of both a high and a low frequency, generated by different parts of the vocal tract. The two-tone sound may help horses convey more complex information.

Scientists find horses produce two sounds at once - a deep vocal tone and a high whistle - revealing how their complex whinny ...
