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
=======
The Palomar–Leiden survey (PLS) was a successful astronomical survey to study faint minor planets in a collaboration between the U.S Palomar Observatory and the Dutch Leiden Observatory, and resulted in the discovery of thousands of asteroids, including many Jupiter trojans.
The original PLS-survey took place in 1960, and was continued by three Palomar–Leiden Trojan survey campaigns, launched in 1971, 1973 and 1977. Its principal investigators were the astronomers Ingrid and Cornelis van Houten at Leiden and Tom Gehrels at Palomar. For the period of the entire survey (1960–1977), the trio of astronomers are credited with the discovery of 4,637 numbered minor planets, which received their own provisional designation, such as 6344 P-L, 4835 T-1 and 3181 T-2.
PLS was one of the most productive minor planet surveys ever conducted: five new asteroid families were discovered, gaps at 1:3 and 2:5 orbital resonances with Jupiter were revealed, and hundreds of photographic plates were taken with Palomar's Samuel Oschin telescope. These plates are still used in their digitized form for the precovery of minor planets today.
