A manned rocket can reach the moon in less time than it used to take to travel the length of England by stagecoach. @LAQMC

Time passes more slowly in orbit around the earth. This means returning astronauts arrive home slightly younger than if they had spent the same amount of time on earth. @LAQMC

Astronomers believe that space is not a complete vacuum, there are three atoms per cubic metre. @LAQMC

Galaxies are sprawling space systems composed of dust, gas, and countless stars. The number of galaxies cannot be counted the observable universe alone may contain 100 billion. Some of these distant systems are similar to our own Milky Way galaxy, while others are quite different. @LAQMC

The atmosphere on Earth is proportionately thinner than the skin on an apple. @LAQMC

Neighboring Andromeda Galaxy is approaching our galaxy at speed somewhere around 100 to 140 kilometers per second, which means that The Milky Way may collide with Andromeda galaxy in 3 to 4 billion years. @LAQMC

Ever wondered how the pull of gravity is calculated between heavenly bodies? It's simple. Just multiply their masses together, and then divide the total by the square of the distance between them. @LAQMC

Over 500 people have flown into space - about 0.000007% of the world's population. @LAQMC

The most famous comet of them all, Halley's comet loses one meter of its surface (ice) each time it comes near the Sun. @LAQMC

Extrasolar planets, or sometimes called exoplanets are planets beyond our solar system, orbiting a star other than our Sun. @LAQMC

The Spitzer Infrared Telescope recently discovered another ring around Saturn. @LAQMC

The oldest star in Milky way galaxy is 13,2 billion years old, almost as old as the Universe itself. @LAQMC

In honor of the original thirteen states, the U.S. $1 bill has the following on the back: 13 steps on the pyramid. The motto above the pyramid has 13 letters (annuity coatis). E pluribus Unum, written on the ribbon in the eagle's beak, has 13 letters. 13 stars appear over the eagle's head. 13 stripes are on the shield. 13 war arrows are in the eagle's left talon. @LAQMC

Mars's moon Phobos orbit's the red planet so fast that it completes 3 orbits in one Martian day @LAQMC

The most dangerous asteroids, those capable of causing major regional or global disasters, usually impact the Earth only once every 100,000 years on average. @LAQMC

The density of the dark matter in a galaxy has its maximum in the center and it gradually decreases as it gets to the outermost part, but the same process significantly increases the total size of the galaxy. @LAQMC
