Artificial Solar Eclipse Achieved: ESA’s Proba-3 Mission Unveils new Corona Insights
Paris – In a groundbreaking achievement, the European Space Agency (ESA) has successfully engineered an artificial solar eclipse, providing scientists with an unprecedented opportunity to study the enigmatic solar corona. This mission, spearheaded by the Proba-3 satellite duo, is poised to unlock pivotal information regarding solar winds and coronal mass ejections (CMEs), phenomena that considerably impact space weather and, consequently, our planet.
Proba-3: A Mission of Millimetric Precision
The European Space Agency’s (ESA) Proba-3 mission, designed specifically for creating artificial solar eclipses, represent a significant leap forward in solar observation technology. This innovative mission utilizes two coordinated satellites, the Coronagraph and the Occulter, flying in precise formation to mimic a natural eclipse.
Launched from the satish Dawan Space Center in India last December, the two satellites have maintained a consistent distance of 150 meters since march of this year. The Occulter, equipped with a 1.4-metre diameter disc, precisely blocks the sun’s glare, casting an 8cm shadow onto the Coronagraph.

This meticulous alignment allows the Coronagraph’s advanced imaging instruments to capture detailed images of the solar corona, a feat previously limited to the brief moments of natural solar eclipses.
Unlocking the Secrets of the Solar Corona
Scientists are particularly interested in the solar corona because of its extreme temperature, which inexplicably exceeds one million degrees Celsius, far surpassing the sun’s surface temperature of approximately 6,000 degrees Celsius. Understanding the mechanisms behind this coronal heating is one of the most significant unsolved problems in astrophysics.
Moreover, studying the corona is crucial for predicting and mitigating space weather events. Solar winds and CMEs, originating from the corona, can disrupt satellite communications, power grids, and even pose risks to astronauts.
By observing the corona with unprecedented clarity, Proba-3 is expected to provide new insights into the origins and behavior of these phenomena.
Artificial Eclipse vs. Natural Eclipse: A Game Changer
While natural solar eclipses offer valuable opportunities for coronal observation, they are infrequent and geographically restricted. Proba-3 offers a distinct advantage by generating an artificial eclipse every 19.6 hours.
“If there is a difference, the real total solar eclipse can only happen once or twice a year, while the Proba-3 can create an artificial containment in every 19.6 hours,” said an ESA Official.
This frequent and controlled observation capability will enable scientists to conduct long-term studies of the corona’s dynamics, leading to a more thorough understanding of solar activity.
Key Differences Between Artificial And Natural Solar Eclipses
| Feature | Natural Solar eclipse | Artificial Solar Eclipse (Proba-3) |
|---|---|---|
| Frequency | Once or twice a year | Every 19.6 hours |
| Location | Geographically restricted | Controlled, on-demand |
| Duration | Limited to a few minutes | Perhaps longer, controlled duration |
| accessibility | Requires travel to specific locations | Data accessible to researchers globally |
The broader Implications of solar Research
The study of the sun’s corona extends far beyond mere scientific curiosity.Understanding the processes that drive solar activity is essential for protecting our technological infrastructure and ensuring the safety of space missions.
