INTERESTING FACTS ABOUT
SPACE

2. Space is silent

Space is completely quiet. Sound is a
wave that needs something to travel
through, like air. Since space is a
vacuum with nothing in it, sound waves
can't travel.

3. The smell of space

Astronauts say that after a spacewalk,
their spacesuits smell like fried meat, hot
metal, and smoke. This probably
happens because atomic oxygen reacts
with the surface of the suit.

4. The Milky Way has more than 100 billion stars

Our galaxy is huge. If you counted one
star per second, it would take you more
than 3000 years to count to 100
billion.

5. Sunsets on Mars are blue

On Mars, the sky is reddish during the
day, but sunsets are blue. This happens
because of the way dust in the
atmosphere scatters light.

6. There`s a «diamond planet» in space

One star has a planet that scientists call
"55 Cancri e." According to one idea, a
large part of its surface could be made of
graphite and diamonds.
