Between Earth and the Sun, space is not truly empty but is filled with a soup of charged particles called plasma. This plasma comes from the Sun, pumped out in a steady stream called the solar wind and sporadically blasted away in explosive solar eruptions. When this solar plasma strikes Earth, it causes the magnetic field lines and plasma around Earth to vibrate like the plucked strings of a harp, producing ultralow-frequency waves.

In 2007, NASA launched five satellites to fly through Earth’s magnetic “harp” – its magnetosphere – as part of the THEMIS mission (Time History of Events and Macroscale Interactions during Substorms). Since then, THEMIS has been gathering a bounty of information about plasma waves across Earth’s magnetosphere. 

The frequencies of the waves THEMIS measures are too low for our ears to hear, however. So a NASA citizen science project called HARP – or Heliophysics Audified: Resonances in Plasmas – has sped up the waves recorded by THEMIS to convert them to sound waves.

In this clip from March 17-20, 2012, whistle sounds are repeatedly heard over ambient background whooshes and crunches. The whistles change in pitch as a THEMIS spacecraft moves toward and away from Earth on three orbits, with a maximum altitude of about 50,000 miles. These sounds are related to Earth’s magnetic harp, which has longer magnetic strings and lower pitches farther away from Earth. These three orbits happened near the end of a geomagnetic storm when the solar wind was blowing past Earth with speeds up to about 1,300,000 miles per hour, which is fast even by solar wind standards! There’s often more harp activity during fast solar wind conditions and geomagnetic storms. At the same time, many other types of magnetic vibrations occur during geomagnetic storms, most of which sound like background whooshes and crunches.

New track from Moss Covered Technology; forthcoming on Fluid Audio...

Dartmoor! thou wert to me, in childhood's hour, 
A wild and wondrous region. Day by day 
Arose upon my youthful eye they belt 
Of hills mysterious, shadowy, clasping all 
The green and cheerful landscape sweetly spread 
Around my home; and with a stern delight 
I gazed upon thee. How often on the speech 
Of the half-savage peasant have I hung, 
To hear of rock-crowned heights on which the cloud 
For ever rests; and wilds stupendous swept 
By mightiest storms; of glen, and gorge, and cliff, 
Terrific, beetling o'er the stone-strewed vale; 
And giant masses, by the midnight flash 
Struck from the mountain's hissing brow, and hurled 
Into the foaming torrent; and of forms 
That rose amid the desert, rudely shaped 
By Superstition's hands when time was young; 
And of the dead, the warrior dead, who sleep 
Beneath the hollowed cairn!  My native fields, 
Though peerless, ceased to please.  The flowery vale, 
The breezy hill, the river and the wood, 
Island, reef, headland, and the circling sea, 
Associated by the sportful hand 
Of Nature, in a thousand views diverse, 
Or grand, or lovely, -to my roving eye 
Displayed in vain their infinite of charms; 
I thought on thy wild world, -to me a world,- 
Mysterious Dartmoor, dimly seen, and prized 
For being distant and untrod; and still 
Where'er I wander'd, -still my wayward eye 
Rested on thee!

In sunlight and in shade, 
Repose and storm, wide waste! I since have trod 
Thy hill and dale magnificent. Again 
I seek thy solitudes profound, in this 
Thy hour of deep tranquillity, when rests 
The sunbeam on thee, and thy desert seems 
To sleep in the unwonted brightness, calm, 
But stern; for though the spirit of the Spring 
Breathes on thee, to the charmer's whisper kind 
Thou listenest not, nor ever puttest on 
A robe of beauty, as the fields that bud 
And blossom hear thee. Yet I love to tread 
They central wastes when not a sound intrudes 
Upon the ear, but rush of wing or leap 
Of the hoarse waterfall. And oh, 'tis sweet 
To list the music of thy torrent-streams; 
For thou too hast thy minstrelsies fro him 
Who from their liberal mountain-urn delights 
To trace thy waters, as from source to sea 
They rush tumultuous. Yet for other fields 
Thy bounty flows eternal. From thy sides 
Devonia's rivers flow; a thousand brooks 
Roll o'er they rugged slopes; -'tis but to cheer 
Yon Austral meads unrivalled, fair as aught 
That bards have sung, or Fancy has conceived 
'Mid all her rich imaginings: whilst thou, 
The source of half their beauty, wearest still 
Through centuries, upon they blasted brow, 
The curse of barrenness.

Lake Ulubat is a large freshwater lake in the vicinity of Bursa in Turkey, hosting a large amount of bird species.
While a lot of activity can be heard during the birds breeding season, it sounds really quiet under the beating sun of summer.
Submerging hydrophones between alga in the shallow water reveals a whole new world as numerous little insects sounds really busy.
