We’re used to thinking of space as continuous.
A stone can be anywhere in space. It can be here. Or it can be an inch to the left. Or it can be half an inch further to the left. Or it can be an infinitesimal fraction of an inch even further to the left. Space is infinitely divisible.
Some of the moons hadn’t been spotted yet because they are tiny, measuring less than 1 mile in diameter. Astronomers discovered 12 new moons orbiting Jupiter, meaning the total number of moons we know to be orbiting the gas giant now stands at 92.

On September 24, 2023, the sample return capsule will detach from the spacecraft, perform an entry, descent and landing sequence, and touch down in the Utah desert.
Thanks to our contribution to the mission, Canada will receive a portion of the asteroid material!

The discovery is putting into question everything astronomers believed about ring systems.
Astronomers from the University of Sheffield discovered a new ring system around a dwarf planet on the edge of the Solar System, according to a press release. The discovery calls into question current theories about how ring systems are formed since the ring system orbits much further out than is typical for other ring systems.
Around a dwarf planet.

After the news in January of the James Webb Space Telescope spying rings around Chariklo—a tiny world over two billion miles away from Earth—new research reveals another remote ringed world in the solar system.
Quaoar (pronounced “kwar-waar”) is a dwarf planet about 700 miles/1,110 kilometers in diameter—about half the size of Pluto—that orbits the Sun beyond Neptune in the remote and cold Kuiper belt region. It has a tiny moon called Weywot.
Scientists have found rings around Quaoar, a small body in the solar system about half the size of Pluto.
