In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible.

Today, the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 "winning" the race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the solar system. Moreover, the notion that America "won" the Space Race at the end of the 1960s overlooks just how competitive the Space Race actually was in launching people into orbit.

While modern technology has helped astronomers view the furthest reaches of the Solar System, it has also allowed scientists to start discovering planets orbiting distant stars. To make it easier to assess the relative mass and size of the new planets being discovered, scientists give these measurements as multiples of those properties for either Jupiter or Earth

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Lacking the means to prove otherwise, discussions of an alternative to Earth’s solitary existence have remained conceptual. The ongoing debate is spurred by the appearance of unexplainable phenomena through the centuries in the atmosphere and the space beyond, so much so that contact with alien civilizations has been depicted in some of the most ancient examples of representational art.

Before the advent off the wireless technology era, the existing communication technologies were primarily powered by wired technology. From the telephone to the fax machine, communication was not possible without a physical connection between the communication device and the source of the power of the device. For instance, there had to be a connection between a wired telephone and the dial board for communication to be possible. Just as with every other wired device, wireless communication has successfully displaced wired communication.
