A Contradictory Claim on Sun Came from Indian Scientists

New Delhi: About a month ago, us space agency NASAsaid solar flares are more active during this period as the new solar cycle begins. On the contrary, Indian space scientists claim that the sun is calmer than before. The new study says that between 2008 and 2019, the sun has been calmer than it was from 1996 to 2007. The study has been conducted by the Indian Institute of Astrophysics (IIA), Bengaluru.

The behavior of the sun has already changed

Scientists at the Indian Institute of Astrophysics (IIA), Bengaluru say that coronal mass effects from the sun have already weakened. Scientists are trying to understand the coronal mass effects and the effects (ICMEs) on their other planets during the 23rd and 24th solar cycles. The research paper published in Frontiers in Astronomy and Space Science provides information and mentions the change.

The study of coronal mass ejection is essential

Coronal mass ejection refers to the emission of plasma and magnetic fields from the surface of the sun into space. The emission from the sun during 11 years is divided into three parts, ascending, maximum, and declining, which complete a solar cycle. Scientists have reported that CMEs need to be examined at different distances from the sun and study changes in them and help understand astronomical events.

Two-thirds less than the previous cycle

The average size of the solar cycle 24, that is, the coronal mass injections (CMEs) between 2008 and 2019, has decreased by two-thirds compared to the previous cycle. This is shocking because reduced pressure means that CMEs are spreading more in space than before. Scientists have found that gas pressure in the 24th cycle was only 40 percent compared to the 23rd cycle.

What are coronal mass effects?

In easy language, coronal mass effects can be understood from sun emissions. Such emissions are caused by flames emanating from the surface of the sun and plasma, gas and magnetic fields are part of them. Changes in the sun's magnetic field are the cause and such emissions can affect other planets as well.

Should we worry about this?

After CMEs emerge from the surface of the sun, their speed in space can range from 250 km per second to 3,000 km per second. At this speed, it takes 15 to 18 hours for CMEs to reach the earth. That is, the earth gets less time to prepare and after it is warned. However, such a change will not have any immediate major impact on the earth, so there is no need to worry.
