A teaspoon-full of Neutron star would weigh about 112 million tonnes.
Even on clear nights, the human eye can only see ~3,000 stars. There are an estimated 100,000,000,000 in our galaxy alone!
Betelgeuse, the star on Orion's top-left shoulder, is so big that if replaced the sun, it would swallow up Earth, Mars and Jupiter!
Halley’s Comet was last seen in 1986. It will be visible again from Earth sometime in 2061 (get your camera ready!)
If you could travel to the nearest star in a car at 70 miles an hour, it would take 356,908,917,036 years!
