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
=======
Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat) is a NOAA space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 launch vehicle on February 11, 2015, from Cape Canaveral. This was NOAA's first operational deep space satellite and became its primary system to warn Earth in the case of Solar magnetic storms.It was originally developed as a NASA satellite proposed in 1998 by then-Vice President Al Gore for the purpose of Earth observation. It is in a Lissajous orbit at the Sun–Earth L1 Lagrangian point, 1.5 million km (930 thousand mi) from Earth, to monitor variable solar wind condition, provide early warning of approaching coronal mass ejections and observe phenomena on Earth, including changes in ozone, aerosols, dust and volcanic ash, cloud height, vegetation cover and climate. At this location it has a continuous view of the Sun and of the sunlit side of the Earth. The satellite is orbiting the Sun–Earth L1 point in a six-month period, with a spacecraft–Earth–Sun angle varying from 4 to 15 degrees. It takes full-Earth pictures about every two hours and is able to process them faster than other Earth observation satellites.The DSCOVR satellite finished production in the late 1990s but was kept in storage at the NASA Goddard Space Flight Center in Maryland. After being stored away for so long the satellite was put through a series of tests and underwent maintenance to ensure the viability of the aircraft for launch. DSCOVR started orbiting around L1 by June 8, 2015, just over 100 days after launch. After the spacecraft arrived on site and entered its operational phase, NASA began releasing near-real time images of Earth through the EPIC instrument's website. The National Oceanic and Atmospheric Administration (NOAA) operates DSCOVR from the NOAA Satellite Operations Facility in Suitland, Maryland. The acquired space data that allows for accurate weather forecasts will be carried out in the NOAA Space Weather Prediction Center in Boulder, Colorado. Archival records will be held in the NOAA National Geophysical Data Center for further processing carried out by NASA.
