Red Square Nebula

This interstellar glowing plasma giant around a dying star is unusual because only ~ 10% of nebula are bipolar, and in this instance its orientation relative to us provides a unique square view of its dust, plasma, and gas that surrounds its central dying star.

Supernova SN2023rve was discovered using UAE's Al-Khatim Observatory.

This barred spiral Galaxy, NGC 1097, is about 45 million light-years distant from Earth within the constellation Fornax and it was discovered in October 1790 by William Herschel. Two exposures* taken months apart easily reveal the supernova's position within the stellar galactic field-of-view.

The "Tadpole Galaxy" features a lot of massive bright blue star clusters.

It's only 420 million light-years distant, with a "tail" that is about 280 thousand light-years long. Tidal forces likely produced this magnificent view when another "intruder" galaxy passed nearby long-ago forming its spectacular unique feature.

The most volcanic planet in our solar system: Io - as imaged by the Juno spacecraft.

Although Io is technically outside the Roche Limit, tidal forces are effectively causing internal heating.

Asteroid Bennu

Asteroid Bennu.jpg

"NASA’s OSIRIS-REx spacecraft snagged 121.6 grams of pristine space rocks when it bopped the asteroid Bennu four years ago." *

"When that object formed, material came together, brought ices with it — and not just water ice, but carbon monoxide and ammonia ice — which means it had to accrete somewhere out past what we call the snow line, out past Mars in the outer solar system. At that distance from the sun, temperatures are low enough for those ices to form."

Here is an image of how polarization affects matter and energy along its circumference of Milky Way's black hole.

"This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of Sagittarius A*."

In this moving reference frame the image shows a strong-ordered electromagnetic field also found in another black hole in M87. "CfA postdoctoral fellow and SAO astrophysicist Paul Tiede said, "It is exciting that we were able to make a polarized image of Sgr A* at all. The first image took months of extensive analysis to understand its dynamic nature and unveil its average structure." *

I'm thinking that this phenomena is another example of frame dragging.
