Starship Asterisk*

Thank you.

Is it possible that as the sun ejects material into space that it thrusts the sun onto a new course or direction, and that the solar system follows that new course?

How often has gravitational lensing been observed to date?

I am not an astronomer, so my first thought on seeing the object referred to by Chris Peterson was, a man-made satellite. It does appear to be partially blocking a bright area, giving the object a pinched waist. I suppose it would be visible in other space photos of the region if the object is stell...

The question is: What is the general process that activates a star's nuclear burn, and is there a shockwave when ignition begins? What might that shockwave's frequency be and could it be discerned?
