The Great Red Spot measures about 13,700 km wide in this image, slightly more than Earth's diameter of 12,750 km. I used the "Hello, World" image from Artemis II to make a comparison between our home and the largest planet in the Solar System.

Saturn is back! After passing behind the Sun in late-March, Saturn is rising out of the morning twilight. The southern hemisphere is tilted more towards us than last year as it moved away from last year's equinox and towards the next solstice in 2032. #Astronomy #Astrophotography

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. #Astronomy #Astrophotography
