Pulsars, research, debates…


Pulsars — tiny spinning stars, heavier than the sun and smaller than a city — have puzzled scientists since they were discovered in 1967. Now, new observations by an international team, including University of Vermont astrophysicist Joanna Rankin, make these bizarre stars even more puzzling.

The scientists identified a pulsar that is able to dramatically change the way in which it shines. In just a few seconds, the star can quiet its radio waves while at the same time it makes its X-ray emissions much brighter.

The research “challenges all proposed pulsar emission theories,” the team writes in the Jan. 25 edition of the journal Science and reopens a decades-old debate about how these stars work. [1]

I remember years ago when I first read about pulsars. At first, I had the impression that scientists knew how they worked. So many pictures, so many diagrams, so many written papers.

It just took me a while to realize that they do not have a clue!

AND NOT! THIS IS NOT BAD! This is the very essence of science! This is what being a scientist actually mean! To explore and try to understand unknown phenomena in the universe and the cosmos!

So my only question about the abovementioned “news” is: when was the debate about pulsars “closed” ?!?
