So what happens to planets or other rocky bodies when a star like our Sun, at the end of its life goes through its Red Giant phase, thowing off its outer layers forming a planetary nebula that eventually disperses after 10,000 to 20,000 years? Well this study shows that 21 white dwarfs have a single ring of debris around them but WD J1328-1450 actually has TWO rings around it! In the video I discuss this and review the article!

The Vera C Rubin Observatory has found ED138 a Trans Neptunian Object that is out beyond the orbit of Pluto at 46 Astronomical Units (Pluto is at 40 AU; and 1 AU is the distance from the Earth to the Sun) and is between 600 to 1500 kilometers in size which object and size woudl make it round and classify it officially as a dwarf planet.
In this video I go through the article announcing this and yes, I quote from it. Exciting stuff!

Well, 3I/Atlas as a comet may not be so different or weird after all! A new study just published ocmpared the micron grains of dust off 3I/Atlas to comets in our Solar System an to objects that are Trans-Neptunian, objects out beyond Neptune and found that with those Trans-Neptunian objects that 3I/Atlas has several traits that are similar to those objects!

Gemini North telescope was used by a team of astronomers led by Timothy Cunningham (Center for Astrophysics — Harvard & Smithsonian) and Ilaria Caiazzo (Institute of Science and Technology Austria), reveals about ten times more filamentary structure in Pa 30 than previously seen. It also shows that the radial filaments are made of consistent chains of tiny knots of gas, rather than smooth streaks as previously thought. This knotty structure suggests that there may have been thermal or density variations in the circumstellar medium that shaped the supernova ejecta as it expanded radially away from the explosion.
