The largest known crater on Earth, the Chixulub crater in Mexico is 112 miles (180 km) across.

Atoms are 99.9999999999999% empty space, which means all the matter making up the entire human race could fit into a cube of sugar!

The cosmic microwave background radiation is the furthest back in time we have data for. It marks a point 380,000 years after the Big Bang when the Universe cooled and became transparent enough for radiation to travel. Before this point the universe was opaque, therefore astronomers can't use any kind of light to see what existed there

The full Moon always rises at sunset and sets at sunrise.

The Sun looks 1600 times fainter from Pluto than it does from the Earth.

A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5×1012 kg (that is 1100 tonnes per 1 nanolitre), about 900 times the mass of the Great Pyramid of Giza.

A supermassive black hole is believed to be present in the centre of nearly every galaxy, including our own Milky Way.

Jupiter's moon Io has "land tides", from the gas giant's gravitational pull. The land of Io actually rises falls by as much as 100 metres, as well as cracking and splitting apart as Jupiter pulls on it

Jupiter's centre is a place of extremely high pressure, so high that the core of the planet is thought be liquid metal, caused by the gases hydrogen and helium changing their form under pressures of 70 million Earth atmospheres

The term "honeymoon" is derived from the Babylonians who declared mead, a honey-flavored wine, the official wedding drink, stipulating that the bride's parents be required to keep the groom supplied with the drink for the month following the wedding.

According to a new study, the inner core of Earth spins nine-thousandths of a second faster than outer layers of the Earth, which may be responsible for the Earth's magnetic field.

From the moon, astronauts brought back 380 kg of Moon rock.

A "Blue Moon" is the second full moon in a calendar month (it is rarely blue).

Even on the clearest night, the human eye can only see about 3,000 stars. There are an estimated 100,000,000,000 in our galaxy alone!

Betelgeuse, the bright star on Orion's top-left shoulder, is so big that if it was placed where the sun is, it would swallow up Earth, Mars and Jupiter!

Earth's collision with some comet is less likely than earth's collision with some asteroid.

Venus rotates so slowly that in a typical day lasts approximately 244 Earth days (5,856 hours).

The term "Big Bang" started as a putdown. In the 1940's, there were many competing theories about the nature of the universe. British astrophysicist Fred Hoyle coined the term "Big Bang" as a snide putdown of his competitors, only to have the term find its way into the general consciousness as the description of the correct theory.
