The images that NASA has been able to capture are magnificent
King Star.
The STEREO mission (Solar TEArrestrial RElations ORbservatory,
by its acronym in English) was launched on October 26, 2006 from Cabo
Cañaveral, Florida, from a NASA Delta II rocket.
Consists of 2 spacecraft (STEREO A and STEREO B), which
when they left Earth's atmosphere they took a highly elliptical orbit, in
this stage the ships A and B were slightly separated. In the heyday of the
geocentric orbits the ships took gravitational pulls of the Moon.
Ship A was the one that went later what produced that
will launch into heliocentric orbit, while ship B was temporarily kept
in the high orbit of Earth.
January 21, 2007 thanks to a last gravitational pull
of the Moon, ship B left the heliocentric orbit in the opposite direction
than your partner A.
Ship A will take 347 days to circle the Sun, increasing its angle by 21,360 degrees per year and
ship B 387 days with a change of -21.999 degrees per year.

On January 24, 2009 they reached the condition of the square
(be at 90 °).
On February 6, 2011 the 2 ships were exactly at
180 ° one from the other.
Even though the angle will increase, no angle will be lost
of vision, because the Solar Dynamics Telescope is in orbit
terrestrial, which will result in a triangulation having the Sun as its center.
In 2015 the signal of the STEREO ships will be lost for several months
because they will be placed on the other side of the Sun.
In 2023 the ships will approach Earth, but they will never enter
in Earth orbit.
Take pictures of the hidden area of the Sun from Earth, with
this can be seen directly solar activity, instead of inferring what is
what happens on the other side.
The STEREO ships will monitor the massive solar wind gusts,
the solar plasma and the magnetic fields that are ejected into space.
This mission is of utmost importance, since it is a precaution to a very
possible disqualification of telecommunications (satellites), airlines and connections
of electrical wiring throughout the world due to the radiation of the ejections of
coronal mass (CMEs) intense. In other words, if the solar wind passes through the magnetosphere, the entire planet may be in shadow.
If this happened, the world would stop completely, and to make everything go back to normal it is estimated that it could take 1 to 2 decades.
Since the Sun rotates every 25 days, the STEREO mission can give
information about a possible danger to the Earth up to 25 days before, what
Enough to prepare us.
In addition, the STEREO mission hopes to make great advances in the theory
solar physics and the prediction of space weather in the Solar System.
