Key Takeaways
- The nearest star, the Sun, serves as a natural laboratory for understanding stellar processes across galaxies.
- ISRO’s Aditya-L1 mission will provide real‑time data on solar eruptions and space‑weather impacts.
- Early detection of solar phenomena helps protect spacecraft and astronaut health.
Chennai: The Indian Space Research Organisation (ISRO) which is gearing up for its first Solar exploratory mission to study the dynamic sun with the planned Aditya-L1 satellite using PLSV in the coming days, said the study of the sun was to know about stars in various other galaxies.
ISRO said The sun is the nearest star and therefore can be studied in much more detail as compared to other stars.
“By studying the sun we can learn much more about stars in our Milky Way as well as about stars in various other galaxies”, it said.
“The sun is a very dynamic star that extends much beyond what we see. It shows several eruptive phenomena and releases immense amount of energy in the solar system. If such explosive solar phenomena is directed towards the earth, it could cause various types of disturbances in the near earth space environment”, it said.
It said various spacecraft and communication systems are prone to such disturbances, so an early warning is crucial for corrective measures.
In addition, if an astronaut is directly exposed to explosive solar phenomena, he/she would be in danger.
The Sun’s various thermal and magnetic phenomena are of extreme nature.
Thus, the sun also provides a good natural laboratory to understand those phenomena which could not be directly studied in the lab.
