SUMMARY: A team of Italian astronomers have discovered that a pulsar racing through the Milky Way has a comet-like trail blazing behind it. The object is called Geminga, and it was previously found to have twin jets of material blasting from its poles. This new, longer tail, was uncovered by studying data archived by NASA's Chandra X-Ray Observatory. Geminga is only 500 light-years away from Earth, and moving quickly across our field of view giving astronomers a unique opportunity to study such an exotic object.

Hi folks!

If the pulsar, while racing through our galaxy, has a comet-like "tail", doesn't this necessarily mean that there IS some sort of ether after all?

I mean, in empty space there is no atmosphere to cause this tail. Also, the star is too far away from any other star to be influenced by solar winds or the like.

Don't you agree?

with kind regards

"Geminga" (http://www.daviddarling.info/encyclopedia/G/Geminga.html)... interesting!


[...] its name is both a contraction of "Gemini gamma-ray source" and an expression in Milanese dialect meaning "it's not there."

It's kind of like that old teacher's joke..."Will all those not present please raise their hands?".....and Geminga did.

"Empty space" is rarely empty. The pulsar is leaving a trail because it is plowing through interstellar gas & dust. It's very thin, but it's there.
