Over the years I have written four letters to The New York Times.Two of them were published which shows that my view points were taken into consideration.

When Will the Sun Die?

In about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago. Once all the hydrogen gets used up, the sun will grow out of this stable phase. With no hydrogen left to fuse in the core, a shell of fusion hydrogen will form around the helium-filled core, astrophysicist Jillian Scudder wrote in an article for The Conversation. Gravitational forces will take over, compressing the core and allowing the rest of the sun to expand. Our star will grow to be larger than we can imagine — so large that it'll envelop the inner planets, including Earth. That's when the sun will become a red giant.

A close-up of one active region on the sun, seen in profile in extreme ultraviolet light, produced an interesting display of dynamic and frenetic sputtering over three days (Aug. 28-30, 2011).
