A Solar eclipsesIn addition to assuming a wonderful show for those who were lucky enough to see him, they A unique opportunity for scientistsThe field while the moon covers part of the solar center, the details of the crown are captured much better, where most of the activity of the star king occurs, which can affect the earth. Unfortunately, the frequency of these phenomena is not too high. Most of all, they happen one or two per yearWith a long time. Therefore, a team of scientists from European Space Agency (ESA) I thought it would be interesting to create Artificial solar eclipse.
The goal was to create it on demand when it was necessary, without waiting for this pair of eclipses, which, at best, get a year of course. In addition, this can be observed for several hours to capture the necessary details with great emotional calm. Now, how can this artificial solar eclipse be achieved?
Logically, the moon cannot be manipulated. Therefore, the only way to create this phenomenon would be used Artificial satellite who inserted between the sun and the observer. It was a goal PROBA-3 Mission And the reality is that the results were more than promising.
How is an artificial solar eclipse created?
The PROBA-3 mission has two ships: Legitimate and coronagram. Both fly together, but did not throw them, at a distance from About 150 meters each other.
Okulter is the one who is responsible for creating an artificial solar eclipse. It acts as a moon during natural eclipses, interaction Between the sun and the observerAs a rule, observers are, we are on Earth, and those people located in places where they are for a short period of time can see them. In this case, we are not talking about seeing it from the Earth, but about taking pictures with the coronafer. That is why both ships are at a very exact distance and place.
Coronagance He has an instrument called Aspiicscapable of observations in different wavelengthsThus, you can get very complete data about the solar crown, which is completely detected without interruptions during an artificial solar eclipse.
Then it’s time to make images
The latest images of the solar eclipse are actually the fruit of the overlap of three types of photographs, with Three different time expositions.
How often can this phenomenon be created?
Scientists responsible for the project explained in the article for The science of warning that an artificial solar eclipse can be created Every 19.6 hoursIn addition, you can hide the sun for 6 hours, so there is a lot of time to observe its crown.
At the moment, in the first photographs, they made images of the crown of the dark sunny sun that demonstrate Iron presence This has lost electrons from high temperatures. There are also yellow images that show The presence of helium. In this color, he was actually captured Great sunny fame. They managed to photograph many times, but never with such a small visual break.
On the other hand, in purple photography Coronal snakes The white light, which is an elongated CUSP form, which can usually be seen during eclipses. And finally, in light green, it is observed As you can see this artificial solar eclipse from the Earth.
Results PROBA-3 They will join those who PROBA-2which analyzes the sun through extreme ultraviolet radiation and Soho Solar Observatorywhich focuses on the external atmosphere.
We are going to learn much more about the sun. This is only the beginning of an exciting mission.
