(1)- Galileo Galilee was the first person to observe Mars through a telescope, in 1609.
(2)- Black holes about 10,000 to 18 billion times heavier than the sun are thought to exist at the centre of galaxies.
(3)- Only 12 people have been on the moon: the astronauts on the Apollo missions from 1969 to 1972.
(4)- NASA is developing 3D printed pizzas for astronauts.
(5)- With its faster orbit around the sun, Venus overtakes Earth every 584 Earth days, changing from an evening star (visible after sunset) to a morning star (visible before sunrise), and then vice versa.
(6)- From the moon, Earth is almost four times the size of a full moon from Earth, and it never moves across the moon’s sky.
(7)- Until quite recently, Venus had been visited by more space probes than any other planet (Mars has now been visited more), with 18 Soviet and six American spacecraft making the trip.
(8)- It wasn’t until 1665 that scientists realized that other moons orbited other planets. Earth’s moon’s official name then became a capitalized “Moon.'.
(9)- The Universe may have neither a centre nor an edge because according to Einstein’s theory of relativity, gravity bends all of the space-time around into an endless curve.
(10)- The first African American in Space was Guion “Guy” Bluford, Jr., who was aboard the space shuttle Challenger in 1983 as well as 3 other shuttle flights (one other on Challenger and two on Discovery). Mae Jemison was the first African American woman in space. She flew aboard Endeavour on September 12, 1992.
(11)- In 1965, the United States spacecraft Mariner 4 made the first successful flyby of Mars. It took 228 days to reach Mars and sent 22 images to Earth. Many scientists were extremely disappointed that the images showed no signs of oceans or vegetation that they thought it would find. In 2008, however, scientists believe they found significant evidence of carbonates in certain regions on Mars, which suggests that liquid water and perhaps even life once existed there.
