The Chinese rover Yutu-2 rolled down tracks on the Chang'e-4 lander and set off to explore. It's on the floor of the 186 km wide Von Kármán Crater near the Moon's South Pole.

Surface features on asteroid Ryugu have been named based on the theme of names that appear in children's stories. The naming process has been agreed between JAXA [the Japanese space agency] and the International Astronomical Association (IAU). The asteroid's name itself comes from the Japanese fairy tale of Taro Urashima. However Trinitas and Alice's Wonderland are only nicknames which aren't recognized by the IAU.

The Hubble Space Telescope imaged Comet Borisov and caught a distant galaxy in the frame. It's the second known interstellar object to pass through the Solar System.

The galaxy’s bright central core is smeared in the image because Hubble was tracking the comet. Borisov was approximately 326 million kilometres from Earth in this exposure. Its tail of ejected dust streaks off to the upper right.
