Astronomy Picture of the Day -- Wolf-Lundmark-Melotte
NASA ^ | Thursday, April 07, 2016 | (see photo credit)

Explanation: Named for the three astronomers instrumental in its discovery and identification, Wolf - Lundmark - Melotte (WLM) is a lonely dwarf galaxy. Seen toward the mostly southern constellation Cetus, about 3 million light-years from the Milky Way, it is one of the most remote members of our local galaxy group. In fact, it may never have interacted with any other local group galaxy. Still, telltale pinkish star forming regions and hot, young, bluish stars speckle the isolated island universe. Older, cool yellowish stars fade into the small galaxy's halo, extending about 8,000 light-years across. This sharp portrait of WLM was captured by the 268-megapixel OmegaCAM widefield imager and survey telescope at ESO's Paranal Observatory.

Hey, nice, we're actually getting some stars in the APoD again.
The Big One

Can the electrical charge of the sun be determined? Is it + - or neutral? And can the electrical charge of the orbiting planets can be calculated?

Might the grand universe our astrophysicists look outwardly upon be the same dynamic and structure which our atomic scientists try to unlock in micro miniature?

So, it's our DUFF Galaxy?...................

Dwarf galaxies aren’t lonelier than other galaxies, they’re just farther away from other galaxies because they’re too d***ed small. Losers.

Can the electrical charge of the sun be determined? Is it + - or neutral?

Yes, it can be determined. You take a small object of known charge (i.e., in coulombs) - determined in effect by "counting" the number of excess electrons it contains - and place it "near" (a few million kms) from the Sun. Since the Electrostatic Force is 10^37 (one followed by 37 zeroes = ten times a trillion times a trillion times a trillion) stronger than the Gravitational Force, you could effectively IGNORE any gravitational attraction - at least, you could if your test object consisted solely of protons or of electrons. (But it's easy to impart a charge even to a plastic comb that is able to overcome the gravity of the entire Earth and wrench bits of paper from it.)

Then observe the movement of the smaller object. Is it repulsed? Attracted? How quickly does it accelerate towards / away from the Sun?

In actual practice, it would probably be easier to send a space probe to, e.g., a comet, measure its charge, and then closely observe the comet's motion in the vicinity of the Sun.

There's your answer!

And remember: We've sent space probes to comets - space probes that were known to be electrically neutral, at blast-off and upon encountering the comets (since a charge would have f**ked up the probes' electronics) - and observed no such mysterious motion.

And can the electrical charge of the orbiting planets can be calculated?

Same principle.

Might the grand universe our astrophysicists look outwardly upon be the same dynamic and structure which our atomic scientists try to unlock in micro miniature?

In both cases: Forces acting upon particles (be those gravitational forces acting upon galaxy-sized particles or eletrostatic forces acting upon atom-sized ones). So: Yes!

Regards,

How do they know that it is lonely? Maybe it is just anti-social.
