Ultraviolet astronomy looks at ultraviolet wavelengths.

The Sun photographed at the ultraviolet wavelength of 304 Angstrom (30.4 nm). 

The sun seen at the ultra violet frequency of 9,861,594 GHz by the observatory in space known as Soho (Solar and Heliospheric Observatory).

The optical surface of the Sun has a temperature of about 6,000 degrees K.

The temperature above the Sun’s surface rises to 1,000,000 degrees Kelvin (1.8 million degrees Fahrenheit).

Every feature in the image is a result of the magnetic field structure of the Sun.

The hottest areas appear almost white, while the darker red areas indicate cooler temperatures.

The Sun's surface before an explosion.

The Sun seen from Space in Ultraviolet before an explosion.

The Sun as seen by the Extreme Ultraviolet Imaging Telescope in Space known as STEREO (Solar TErrestrial RElations Observatory’s.

The Sun’s atmosphere are at temperatures around one million Kelvin (1.8 million degrees Fahrenheit).

The extreme ultraviolet light is not visible to the human eye, so it is represented here in blue.

The charged particles (mostly extremely hot protons and electrons) rising from the active region create a strong magnetic field that pulls the particles into the loops seen here.

Over time, magnetic stress builds in the Sun’s atmosphere until the energy is released in a massive explosion (see the next photo).

The explosion sends a giant cloud of charged particles (a coronal mass ejection) and X-ray solar flares hurtling into space with a force comparable to a billion megaton nuclear bombs.

When the charged particles and X-rays arrive at Earth, they can disrupt communications and power systems and are a threat to satellites and astronauts in space.

The active regions that produce flares are visible from Earth as Sun spots, but the streaming particles emitting ultraviolet light in this image are only visible from space.

Just one week after this image was taken, the Sun spot shown here produced a strong solar flare.

How to build a radio station in Somalia.

How to build a radio station antenna in Somalia.

The completed short wave radio broadcast and amateur radio training antenna in Galkayo, North East Somalia.

 

The completed Radio Free Somalia (“Free for all to use” known later as Radio Galkayo) short wave radio antenna and the front wall of the Galkayo Police station, Galkayo, North East Somalia in August 1994.

Notice the spelling Boliska (The Somali language does not have the letter P, in Somali a P is written as B).

North East Somalia became the Puntland State of Somalia on the 1st August 1998.
