- Saturn is back in the morning sky but something looks different. Just a few days after equinox, it's autumn in the north & spring in the south. The dark line cutting across the planet are the rings, not their shadow. They are very dark when sunlight hits them at a shallow angle. #Astrophotography

- Transit of #exoplanet WD 1856+534 b across its white dwarf host star. An unusual system where we see a small white dwarf star partially occulted by a giant planet every 1.4 days, resulting in a much deeper decrease in brightness than most exoplanet transits. #Astrophotography

- Full Moon Photobomber Two years after catching a previous lunar occultation of Mars before clouds rolled in, I had another chance in January to catch one and create a Moon mosaic as I originally planned to provide a sense of scale. #Astrophotography

- What's interesting about this little speck in the night sky? It is Ceres, the only #DwarfPlanet in the asteroid belt and only object there massive enough for gravity to shape it into a sphere. #Astrophotography
- At it's closest approach to Earth, it appears almost the same size as Europa, so if you can resolve the former with your telescope then you can probably do the same with Ceres. 2024-08-26 3:29 UTC Diameter: 0.6" Altitude: 28° Cibolo, Texas, USA (29° N, 98° W)

- Will we see a second naked-eye comet this month? This is C/2024 S1 (ATLAS), discovered by the ATLAS survey a few days ago. It will reach perihelion on October 28th, only a couple weeks after C/2023 A3 (Tsuchinshan-ATLAS) reaches peak brightness and moves into the evening sky. #Astrophotography
