📖 A Cosmic Address

You live on a rock hurtling through space at 107,000 km/h around a nuclear fusion reactor we call the Sun. That Sun is just one of 200 BILLION stars in our galaxy, the Milky Way. And our galaxy is just one of 2 TRILLION galaxies in the observable universe. Yet despite this mind-boggling scale, we've mapped our cosmic neighbourhood in remarkable detail — from tiny Pluto to the giant gas planets, from rocky asteroids to icy comets.
