The IRIS detected the translucent material around the sun

IRIS (Interface Region Imaging Spectrograh) is a space exploration satellite launched by NASA in June this year. IRIS's mission is to study the physical conditions of the solar chromatogram. After nearly six months of orbiting, IRIS recently sent a series of images of a layer of fuzzy matter that had never been observed before on the surface of our star.

According to the scientists, IRIS's findings may shed some light on the Sun's secrets, such as the rise in temperature from ~ 55378 degrees Celsius at the surface to 999,982 degrees Celsius at the coronary rim.

Every second in orbit, IRIS will record high resolution images with a minimum coverage of 150 miles. The ship is also equipped with a spectrophotometer to analyze sunlight, dividing light into multiple wavelengths to measure the variation in temperature, density and speed. Ground-based supercomputers will help test and compare this data with the Sun's current models.

Bart De Pontieu, IRIS lead scientist at Lockheed Marktin, said: "We have seen unexpected and detailed images of the Sun's intense activity. the surface at velocity, the acceleration is very high while the temperature suddenly increases to hundreds of thousands of degrees. Observation and data from IRIS have posed important challenges to the current theory models. " .

De Pontieu is focusing on the data obtained from IRIS based on the two characteristics of the Sun as a prominence and a gas tube (spicule).

Flames are intense radiation eruptions, lasting from several minutes to many hours on the Sun's surface. They are colder, lower in brightness than the surface and shape like giant rings. The explosion of flames often leads to solar storms. According to the scientists, data from IRIS revealed the subtle and dynamic structures of matter that scanned the flames.

Meanwhile, gas pipes are gas nozzles fired from the Sun's surface at speeds of over 240 thousand km / h and can play a role in heating the coronary rim. Thanks to data from IRIS, scientists can for the first time observe the evolution of gas tubes.

"We have recognized the inconsistency between observing activity from IRIS and existing models. These will be the necessary information to improve knowledge of the Sun. With observing something that We don't understand, we have the opportunity to learn something new, " said Mats Carlsson, an astronomer from the University of Oslo, Norway.

IRIS is part of NASA's Small Explorer program - an effort to raise funds for missions at a cost of less than US $ 120 million. IRIS was developed by Lockheed Martin, weighing only 181kg, measuring 2.1 x 3.6m and using operating energy from solar panels. The IRIS system includes probes and spectrophotometers made by the Solar and Physical Laboratory Lockheed Martin (LMSAL). In addition, IRIS is equipped with a telescope developed by Smithsonian astrophysics.
