Saturn with Tethys, Dione, and Rhea on September 2nd, 2025. 12 years to the night after my first shot of the ringed planet with an EdgeHD 8 and original USB 2.0 ASI120MM.

Jupiter occulted the star a couple hours later as the Sun was rising. Look closely and you can see it become more twinkly in the moments before it disappears, a glimpse of Jovian seeing conditions from my backyard on Earth.

Jupiter was in the line of sight between us and the magnitude 7.9 star HD 61660 on October 13th, appearing as an interloper among the Galilean Moons. It's an orange star 25x more luminous than the Sun and 660 light years away. Europa had a very close pass from home.

A distant view of Mars on June 2nd, 2025, over 2.5x farther than it was at its closest approach in January. Clouds can be seen over Olympus Mons just right of center and the three Tharsis volcanoes to the lower-right of it.

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.

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.
