The story that Betelgeuse will tell

I got curious about stars when I could first see a lot of them in the sky. This happened when I lived away from  Delhi for the first time. We urban sissies hardly see 20 stars on a good cloudless night while at least 100 are visible at a good star viewing site within the circle you can make with your thumb and index finger.

Star gazing is the most humbling hobby. Every time I walk at night when I can see some stars, I can’t help noticing the familiar ones. They’ve remained there as I have changed cities, grown up, gone through the ups and downs of life. Most of these stars are so far away that what we observe today is where the star was tens, hundreds or thousands of years ago.

In the northern hemisphere (where most people live anyway), you can’t miss Orion that looks like this in citylight:orion-city

 

In rural areas, it might look like this:
orion-2

 

The shape and the star names are in this image:

I like to think of stars as witness to our world, and they actually see what our world was like back then and even now! Consider the top left star on Orion,  Betelgeuse – which is pretty bright and is slightly red-ish. It is 427 light years away. That star, when you see it today was at that spot back in 1587. In that time, Delhi looked *very* different. It was when Akbar was the 45 year old ruler of pretty much most of what is India and Pakistan today.

Think about what Betelgeuse will tell a future generation about you in 2441 AD, 427 years from now.

What do you think will remain of you then ?
