Top 10 Astro Stories of 2023You probably know that Jupiter and Saturn, which are our biggest planets, also have the most moons. Their biggest ones were discovered some while back, but there are a lot of small ones now that we have better telescopes. And there's been a bit of competition here. Jupiter had the most moons. And then Saturn. And then Jupiter .... What's the story now?

Top 10 Astro Stories of 2023For a long time, no one thought there was water on the Moon. But it now seems there is quite a lot of water ice around the Moon's south pole. Which country do you think was the first to put a lander near the south pole?

Angie, nine of the moons are in retrograde orbits, i.e., they orbit in the opposite direction of Jupiter's rotation. They're definitely captured objects. As for the other three, which are prograde, who knows?!

Top 10 Astro Stories of 2023Lucy's first target on the 12-year mission was the asteroid Dinkinesh that turned out to be in two pieces. Not mentioned in my article was how Lucy was named. In 1974 a hominim fossil was found that was important in the study of human evolution. The discovery team named her Lucy after a popular 1967 Beatles song. The asteroids could will shed light on the "fossils of planet formation". The spacecraft carries a disc made of lab-grown diamonds on one of its instruments.

Top 10 Astro Stories of 2023Still outraged that Pluto is now a [grrr] dwarf planet? A group of planetary scientists reviewed data and images from the 2015 New Horizons flyby. They believe they've found the remains of a super cryovolcano on Pluto. (A cryovolcano erupts ice rather than lava.) Things are looking up, Little Guy!
