Study shows our Sun is less active than similar stars
Recommended for Preparatory Grades
A recent study has shown that our Sun appears to be far less active than similar stars. This is in terms of brightness variations (changes) caused by sunspots and other similar events.
- Researchers studied 369 stars similar in surface temperatures, size and rotation period to the Sun.
- In particular, they studied the sunspots on the surface of the stars. It showed that other similar stars show about five times more changes in brightness than our Sun.
What is a sunspot?
A sunspot is a spot or patch that appears from time to time on a star’s surface, appearing dark compared to its surroundings. Sunspots help us measure solar activity.
Is this good news?
- Yes. If our Sun was more active than it is now, it could disrupt satellites and communication.
- A ‘too active’ star could also affect conditions for life on Earth. So, a ‘boring’ Sun is not a bad thing.
Researchers also studied historical records of our Sun’s sunspots. These records indicated the Sun has not been much more active than it is now.
Another study has also shown that our Sun is currently going through a ‘lockdown’ period. However, all of this could change in the future.
