Astronomers have discovered new details about the mysterious “hole” on the Sun, which is almost twice the diameter of the Earth. All thanks to the Observatory Atacama Large Milimeter/submilimeter Array (ALMA).

Observatory ALMA still served as a scientist for observations of very faint objects in the distant universe – distant galaxies or protoplanetarne disks around young stars, but may also be used to study objects in the Solar System. Within 30 months of operation in 2014. an international group of scientists accounting millimeter waves and submilimetrowe emitted by the Sun. Latest pictures prove that ALMA is camera is ideal for studies of solar activity.
We are accustomed to observing the Sun in visible light, but there is little it tells us about the dynamic of the surface of our star. To fully understand the mechanisms of action of the Sun, we must study them in the whole range of the electromagnetic spectrum within the mm and submilimetrowym that allows ALMA said Tim Bastian, an astronomer at the US National Radio Astronomy Observatory.
ALMA is usually used to detect radio signals from distant galaxies, but also suitable to look directly at the Sun. This means that it can detect the length of the radio waves that he couldn’t answer any one terrestrial telescope.
Scientists hope that the Observatory ALMA will help to understand the formation of sunspots.
Atacama Large Milimeter/submilimeter Array (ALMA) is the world’s largest radio interferometer, located on the plateau of Chajnantor in the Chilean Andes at an altitude of over 5000 m above sea level. This place has one of the driest atmospheres on Earth, so that the conditions for astronomical observations there is better than anywhere else on the planet. The composition of the Observatory includes 66 radio telescopes with diameters of bowls 12 and 7 meters who are conducting research in the field of millimeter waves and submilimetrowych.
