Transcript of Jupiter

The Discovery of Jupiter
One of the main reasons we know so little about Red Spot is the layer of clouds that wrap around the planet. They obstruct views of the planet's lower atmosphere, and probes studying the storm can only catch glimpses of a few scattered clouds.
NASA astronomers use telescopes like the Hubble telescope to study Jupiter all the way from earth. We've also had eight space-craft go up in space to study Jupiter since 1979. These spacecrafts took pictures to study and hopefully discover more about this massive planet. Scientists also recently launched another spacecraft called Juno in 2011 to directly study Jupiter. It arrived on July 4th of 2016.Its goal is to help understand the origin of Jupiter and how planets form.
What is Jupiter?
The Wonders of Jupiter!
Jupiter- the biggest planet in our solar system. It's so big, it could fit more than 1,300 earths inside it. But how much do we really know about this giant planet?
Jupiter is what's called a
'gas giant planet'. It is mostly made up of gases, such as hydrogen gas and helium,
It gets its striped look from colored gas clouds that wrap around the planet. Another identifiable feature is its famous 'big red dot'.
Wow, that's really cool.
How big is it?
As said before, Jupiter is the biggest planet in our solar system. Compared to Jupiter, our planet is miniscule. Jupiter's equator is 143,000 km, and earths is 40,070.
That is more than three times
bigger than our equator. It's so
humongous, it could easily
fit all of the other planets in our
solar system in it. If it were just
80 times bigger, Jupiter would
be classified as a star rather than a planet.
This is due to both its size and the fact
that its composition is similar to
that of a star's.
Jupiter's Moons
The Big Red Dot
Jupiter is famous for its 'Big Red Dot'. But what is this dot exactly?
Is it a mountain? A crater? No, it is a storm. This colossal storm is twice as big as Earth, with winds that reach 400 mph. Scientists are unsure what gives this storm its reddish color, but there are theories that the ammonium hydro sulfide, ammonia and water in Jupiter's atmosphere may react and give it color. None of these theories are proven, however, and there is still a lot of
mystery surrounding the subject.
Nobody knows who the first to discover Jupiter was, but there have been mentions of it from as early as the fifth century. One of the earliest recorded observation is the Indian text, 'The Surya Siddhanta', in which an attempt to calculate the diameter of Jupiter has been found. There are also records of an Islamic astronomer attempting to work out the same thing.
Thank you for watching!
Jupiter altogether has 69 moons. Technically only 53 of them have been named and confirmed, and another sixteen are yet to be confirmed. All of the moons are fascinating, but the ones which scientists are most interested in, are the first four discovered. Their names are Io, Europa, Ganymede and Callisto. These four planets are the largest that surround Jupiter and together they are called the Galilean satellites. They are named after the man who discovered them in 1610, Galileo Galilei. Io is the most volcanically active body in the solar system. It's surface is covered in sulfur in different colors. Europa is the complete opposite. Europa's surface is covered in thick ice. Scientists have evidence that the ice is
covering a huge ocean that lies underneath. Ganymede is l the largest moon in the entire solar system and is even
bigger than the planet Mercury. Callisto has
markings on its surface that show history
from the very beginning of our solar
