Run the dynamics of the Sun Observatory (SDO) took place on 11 February 2010. Her observations of the Sun will last for the next five years, and scientists expect to receive information about exactly how the Sun affects the climate and chemical processes occurring on Earth. Let’s look at the photos taken with the equipment on board the spacecraft observatory.
1. Passage in the shadow of the moon.
Dark object between the sun and lens equipment on board the spacecraft – the dynamics of the solar observatory (SDO), owned by – is the moon. Thus, in the photo – a partial eclipse.
2. Ring of Fire.
Dense gas cloud in the shape of the loop above the solar surface. Solar prominence, namely the so-called phenomenon can escape for thousands of kilometers into space and stay above the surface of the sun for several months. The length of the largest known prominences, observed in 2010 amounted to 692 000 kilometers. This is approximately equal to the radius of the Sun.
Dark spots are due to the advent of intense magnetic activity, which creates areas of low surface temperature. Sunspots can expand and coalesce with each other – they migrate through the solar surface at speeds of hundreds of kilometers per second. They can reach 80,000 km in diameter, and with the Earth can be seen with the naked eye.
Sunrise over the Earth.
The space shuttle “Atlantis” flies past the Sun during its 30th flight. This photo was taken from the Kennedy Space Center Hubble Space Telescope.
Former NASA astronaut Joseph Tanner in the space shuttle “Discovery” low on the Earth’s orbit during the second expedition of the Hubble Space Telescope. Behind him the water the sun. Low orbit over the sky always appears dark, because the atmosphere is not enough for the diffusion of sunlight.
Originating in the photosphere, the coronal loops reach 96 000 km and can be observed between the bottom of the solar corona and transition layer of the Sun. Drifting along the magnetic field, arc beginning to pull away when the temperature of the plasma and fall to the ground with a speed of 90 km / h when its temperature starts to drop. Scientists have recently suggested that the solar corona is heated to a temperature 300 times higher than the temperature of the surface of the sun.
8. Jet Streams
Similar to the needle spikes rising from the inner surface of the sun the chromosphere at speeds of jet aircraft in excess of 48 000 km / h. Above the surface can be up to 60,000 of these “needles”. Duration of up to 5 minutes
9. View with 360 degrees
Based on data with high resolution, resulting from research observatories, NASA STEREO, this photo shows the two halves of the Sun, taken from two opposite sides of it. This photo is part of NASA’s comprehensive study of solar activity.
