In 2017, Cassini's instruments detected ring rain—icy particles from Saturn's rings raining into its atmosphere at 20,000 liters per second before the probe's fiery dive. This revealed rings are eroding faster than expected.

✨ Space fact
🌌 In the first 3 minutes after the Big Bang, the universe was hot enough to forge light elements like helium and deuterium through Big Bang nucleosynthesis. Heavier elements formed later in stars.

✨ Space fact
Neutron stars pack the mass of our Sun into a sphere just 12 miles wide, making them denser than anything imaginable. Their surfaces endure gravity over a billion times Earth's.

✨ Space fact
🌌 In the first three minutes after the Big Bang, the universe was hot enough to fuse protons into helium, creating 25% of all helium atoms we see today. This primordial nucleosynthesis set the stage for stars and galaxies.

✨ Space fact
Neutron stars spin up to 700 times per second, packing a Sun's mass into a 12-mile-wide ball so dense a teaspoon weighs as much as Mount Everest.
