The famous Pale Blue Dot (Earth) picture taken by Voyager 1 in 1990 when NASA instructed it to look behind one final time at home before it left the solar system forever 

After which it became the first man-made object to reach interstellar space

Great picture, it looks quite lonely.

Tabby's star again. Some weird shit going on there. This is an interesting vid on the star.

Not ashamed to say I went straight to the alien megastructure segment. 

Yeah, Ive watched this about 3 times now and Im still struggling with some of the info presented.

 

The suggestion seems to be every 4.3 years when there's been observations or extrapolated as far back as 1978 and 1930's, there's a massive release of 'fine dust' that dissapates then re appears. There doesnt seem to be any extra infra red light at these time points which, it's suggested should be visible if natural objects are regularly colliding.

 

Also, natural objects wouldnt collide at regular time periods, unless it's just a massive co incidence. Im not sure about the author's interpretation that you'd run out of natural objects that regularly collide though?

 

Whatever is causing the clouds of dust is orbiting near the outer edge of 'Taby's star's' habitable zone. The astronomer was understandably reluctant to be drawn on stellar engineering but did posit it could be an explanation for the regular appearance of the dust, it's disappearance at regular periods.

 

I think the suggestion was the dust cloud which causes the light dip ofsome 8%, would need a planetary body 16 times the size of Jupiter to have the same effect. That wouldnt explain the periodicity of 4.3 years at the suggested habitable zone distance from the star though.

 

Hmmm. Thought provoking and mind blowing all at the same time.

JWST now fully deployed and upto 3 separate Lagrange 2 point 'insertion' burns will happen in the next couple of days.

 

Once that's happened and everything is good, I believe they have to do some fine tuning of the individual mirrors so they act as one big one. First real images expected in May although as other events have happened earlier, we may get lucky!

Have they found any green men yet?
