Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
In solar physics, a spicule is a dynamic jet of about 500 km diameter in the chromosphere of the Sun.  It moves upwards at about 20 km/s from the  photosphere. They were discovered in 1877 by Father Angelo Secchi of the Observatory of Roman Collegium in Rome.
