15203350 The sun was first seen in 3D
Scientists for the first time received a full three-dimensional image of the sun. "Seeing the Sun in 3D can now aids NASA STEREO-A and STEREO-B, which occupied the position exactly opposite each other on opposite sides of the star. More information about this reported in the press release NASA. Video of the Sun in 3D, as well as some information image can be downloaded here. Apparatus STEREO (Solar Terrestrial Relations Observatory – Observatory on the interaction between the Sun and Earth) observed coronal mass ejections – emissions of a large amount of material the solar corona. Such events are important not only for theoreticians studying the nature of the Sun, but also for professionals, supervising the work of electronics, including satellites. The substance of the crown is the ionized gas (plasma), which, when emissions moves with great speed. If the plasma moves toward the Earth, it can damage on-orbit equipment, as well as cause harmful interference to terrestrial installations. In addition, coronal mass ejections can have a negative impact on human health. Observation of the stars of both hemispheres allow specialists more accurately predict the disturbances on the sun. Until now, all satellites are "seen" only one part of the star, so the experts could miss the birth of the spots, if it happens on the other side of the world. STEREO devices were launched in October 2006. They revolve around the Sun in the same orbit as the Earth, but only one satellite is ahead of her and another behind. Opposite each other STEREO-A and STEREO-B are located on Feb. 6, 2011. They work in conjunction with Solar Observatory, SDO, launched in February 2010. It is planned that the unit will operate at least eight years.
