Amazing Interesting Facts About Space

Space is mysterious and beautiful, understand it more with this list of one hundred interesting facts about space, planets, moons and stars!
There are thousands of other planets out there.
Outside of our
Solar System there are thousands of other planets. The extra-solar
planets or exo-planets are in orbit around another star. So far we have
almost 1800 confirmed new worlds, with another 3000 awaiting
confirmation. Astronomers are looking to a star’s goldilocks zone for
planets that may be habitable, just like the Earth. The majority of
planets discovered so far are hot gas giant planets.

In space the skin on your feet peels off!

This is a pretty gross fact but in the micro-gravity environment,
astronauts are not using their feet to walk. Therefore the skin on their
feet starts to soften and flakes off. As laundry facilities do not
exist in space, astronauts will wear the same underwear and socks for a
few days. Those socks then need to be taken off very gently. If not
those dead skin cells will float around in the weightless environment.

On Venus a day is longer than a year.

This is tricky one to get your head around but a year on Venus (that
is the length of time it takes to complete one whole orbit around the
Sun) is 224.7 Earth days. However it takes 243 Earth days to rotate on
its axis just once.

The astronauts were placed in quarantine after returning from the moon.

There is a famous image of President Nixon talking to the Apollo 11
crew consisting of Michael Collins, Neil Armstrong and Buzz Aldrin. This
continued until after the Apollo 14 crew returned safely. After this it
was decided that the Moon did not contain any deadly diseases. The
Apollo 13 crew, who had a malfunction and had to return to Earth, did
not have to be quarantined after their re-entry as they didn’t actually
walk on the moon.

One million Earths can fit inside the Sun.

Ancient astronomers once believed the Earth was at the centre of the
Universe but now we know that the Sun is at the centre of our Solar
System and our planets orbit the Sun. The Sun makes up 99.8% of the
entire mass of the whole Solar System. One million Earths would be
needed to be the same size as the Sun.

You become taller in Space.

Another change to the human body in micro-gravity is that spine
straightens out, as gravity is not pushing you down. In fact you can be
up to as much as 5cm taller in the Space Station.

Extreme weather warning!

Some times on the Earth, especially here in Northern Ireland the
weather can be a bit rubbish! However our weather is awesome compared to
some of the other planets. Jupiter has fast winds and the Great Red
spot, a massive hurricane style storm, has raged there for the last 300
years. Mercury and Mars have extreme temperature changes in the same
day. Venus is a scorching five times hotter than boiling water. Saturn
and Uranus also have extremely fast winds. However Neptune has the
fastest ever wind speeds reaching a staggering 1600mph,

Space is not that far away.

Space officially begins at the universal marker of the Karman Line.
This invisible boundary is 100km above the Earth. In theory if you could
drive your car upwards, you could be in space in less than hour.

The hottest planet is not the closest planet to the Sun.

Even though Mercury is the closest planet to the Sun, it is not
actually the hottest. Mercury does not have any atmosphere meaning that
this planet is only hot in the daytime when it is directly facing the
Sun. At this stage temperatures can rise to 425°C but at night the
planet’s temperature can drop down to a freezing -180°C. Venus is the
hottest planet. Its thick clouds trap the Sun’s heat causing Venus to be
a sizzling 500°C all of the time!

The moon looks bigger on the horizon

There is an optical illusion which makes the moon appear to be larger
the lower it is in the sky. The apparent magnification is not caused by
our atmosphere. It is more of a mind trick. When the moon is closer to
the horizon, it is closer to objects like buildings and trees which
therefore in comparison makes the moon look bigger. However there are
times when the moon really is bigger. During its elliptical orbit the
moon has times when it is actually slightly closer to the Earth
(Perigee) or further from the Earth (apogee). This happens about once a
month, due the moon’s orbit around the Earth. Usually is not noticeable
to the eye. However when a full moon occurs at the same time of the
moon’s perigee it can be called a Super moon and appears 12-14% bigger
than normal!

There’s a moose loose

Eccentric Astronomer Tycho Brahe (1546-1601) believed that the Moon
and Sun orbited the Earth but the other planets orbited the Sun. He
catalogued many stars and objects, and has a crater on the moon, and
supernova remnant named after him. However his wild antics are perhaps
just as interesting. He wore a fake silver nose after losing his real
one in a sword fight and he also had a pet moose which died falling down
the stairs after one to many drinks. When his body was exhumed and
examined in 2010, it is thought that a burst bladder was the cause of
his death not mercury poisoning by a jealous colleague which was
considered a cause of death.Astronauts are literally star sailors

The word astronaut comes from the Greek word “Astron” which means
star and “nautes” which means sailor. The Russian cosmonaut has a
similar meaning from ‘kosmos’ meaning universe and again “nautes”
sailor.

You can cry in space but your tears don’t fall

On-board the International Space Station, water floats like bubbles
or spheres. However the water will cling to a surface until it is
dislodged. This means that tears start to form bubbles around your eyes
as the weightless environment is not causing your tears to fall. This
sounds really cool but it can be dangerous. ESA astronaut Luca Parmitano
suffered a space suit leak whilst on a spacewalk. The water leaked into
his helmet covered his eyes and ears, but thankfully he made it back
into the Space Station unharmed, but if not he could have drowned in
space.

Dirty underwear and toilet paper has helped grown plants on the ISS

American astronaut Don Pettit discovered that by folding a pair of
underpants into a sphere shape and stitching in some Russian toilet
paper (which is thick, wool like gauze), this created a warmer
environment for some tomato and basil seeds to start to sprout. Like
their socks, underwear is only changed every 3-4 days so he figured the
pants might provide some extra nutrients for the plants!

There is a dwarf planet named after an Easter island legend

Dwarf planet Makemake was discovered at Easter 2005. The Easter
Island Moai figures were the inspiration for its name. Makemake in Rapa
Nui mythology was the creator of humanity and the god of fertility. He
is also a feature in many rock and cave drawings on the island.

Nebulae come in all shapes and sizes

Nebula means cloud in Latin. These are areas in which stars are being
created or where a star has died. The cosmic clouds come in all shapes
and sizes and are made out of interstellar dust and gases. There is a
Christmas tree nebula, a horsehead, a unicorn, a hand, fried egg and
lots more. These beautiful clouds which are not visible to the naked eye
really highlight the fact there is a lot more happening in the night
sky than you can see.

The North Star will change…eventually

The North Star used for navigation, a steady point in the night sky
will change, however not in our lifetime. The Earth is rotating like a
spinning top and therefore the pole of our planet wobbles. Currently it
points to Polaris but in the year 13727 our Pole Star will be the star
Vega, in the constellation of Lyra. Vega was the also North Star in
12000BCE.

The Apollo crews did not have any life insurance.

On the chance that the 3 man crew of Armstrong, Aldrin and Collins
did not return safely from the moon, they were not covered by any life
insurance policy. So before their trip all 3 men signed photographs that
could be sold in the event of their death. These Insurance covers were
also stamped and posted on the start date of the mission, July 16th 1969 by a friend.

In space metal sticks together

In a vacuum like space, when two pieces of metal touch each other
they bond together. This is a process called cold welding. On the Earth
because of the oxygen in our environment this does not happen naturally
but it is used during some manufacturing processes. It is something to
take into account but it is not usually a problem as the astronaut’s
tools maintain an oxide layer even when leaving Earth.

The furthest manmade object is Voyager 1. It has messages for aliens on-board.

In 1977, Voyager 1 and 2 were launched. Their primary mission was to
visit Jupiter and Saturn. Voyager 2 continued onto Uranus and Neptune;
Voyager 1 has now made its way into interstellar space. Voyager 1 is
further away from Earth than the distance between the Sun and Pluto.
Both craft carry a golden record on board, which will act like a
time-capsule of Earth. It has greetings from Earth as well as different
kinds of music. It also has noises of rocket engines, the sea, people
talking, animal’s sounds and lots of images. All of which sum up the
Earth. United States President Jimmy Carter said at the time “This
record represents our hope and our determination, and our good will in a
vast and awesome universe.” These messages have been recorded as
electronic impulses which can be translated into written words. If any
aliens find it then can enjoy some Louis Armstrong as well some Peruvian
panpipes!
