Measured at roughly 1 kelvin, the Boomerang Nebula is even colder than the background of space itself.

Despite being far from the Sun, Neptune spins rapidly, completing one rotation in about 16 hours.

Sunsets on Mars appear blue to the human eye because its thin atmosphere scatters sunlight differently, favoring the blue part of the spectrum.

Unlike most planets, Venus rotates in the opposite direction of its orbit, so the Sun would rise in the west and set in the east.

A sugar‑cube‑sized amount of neutron star material would weigh about a billion tons on Earth.

Each year, the Moon drifts about 3.8 centimeters farther from Earth, gradually lengthening our days over millions of years.

The Great Red Spot—a giant storm on Jupiter—has been shrinking for decades and is now about 1.3 times Earth's diameter.

Photons emitted from the Sun’s surface take about 8 minutes and 20 seconds to arrive at Earth.

Mercury rotates so slowly that one full day–night cycle equals about 176 Earth days.

Advanced measurements suggest our observable cosmos contains roughly two trillion separate galaxies.
