“One Star Over, a Planet That Might Be Another Earth”

by Kenneth Chang

The New York Times, August 24, 2016



I copied a friend of mine on this article. He emailed me back as follows:

Roger — yes I saw this exciting piece. What amazes me is that this planet is described as relatively close but is in fact a trillion miles away or so.



I replied to my friend as follows:


A couple of things:

Kenneth Chang, the NY Times’s lead science writer is excellent.

They used to have some boring ones (science writers) years ago.

I am woefully uninformed and poorly educated in science, but I find this sort of stuff fascinating.

To get to the planet Proxima b, traveling at incredibly fast speeds, would take something like a hundred (or is it fifty?) years.

Given its distance from us in light years, it would take around four and a half years merely for a signal or electronic message sent from there to reach us (and vice versa).

Another thing (or two):

We know that life on earth originated from a “primordial soup” … there were four basic elements present that made life possible.

It seems certain that life could originate elsewhere.

Planets that could be habitable keep being discovered orbiting other stars … this is only beginning because of powerful telescopes that we didn’t have before which are orbital.

It seems to me now — considering the arc of discovery, as it were — that there is no question whatsoever that there is life on other planets — there are so many stars in the universe, including the zillions with planets orbiting them, it boggles the mind.

Of course there are! I would be inclined to say — definitely, inarguably. There are habitable planets out there with a form of life. We just haven’t reached or contacted them.
