Transcript of Astronomy Timeline

Newtonian Telescope 5000 By Brandon Witkin and Reece Bowen In Egypt and Mesopotamia,
the first lunar-solar calendar
is introduced. This is an important event because lunar-solar
calenders are astronomical. They have you
track the moon and the sun. 2,000 B.C.E. 3,000 B.C.E. In England, Stonehenge is built. This event is important as some people think
that Stonehenge was used to predict solar and
lunar eclipses. In theory, it was very astronomically
advanced. 240 B.C.E. In Cyrene, Eratosthenes measures the
circumference of the Earth. This event is important as it gives us more knowledge
of our planet. How would we travel in space or study
astronomy without much of a knowledge of circumference. 130 B.C.E. In Greece, Hipparchus develops the
first accurate star map This is important because it helped with
navigation. It is important for navigation
in space, and here on Earth. 45 B.C.E. In the Roman Empire, the Julian
Calendar is introduced. This event was important, as the Julian
Calendar was a solar only calendar.
Knowing dates and time is very
important in travel and
astronomy. 1054 C.E. In China, Chinese astronomers
observe the supernova at Taurus. This event is important as it helped us
understand supernovas. Today we
believe that supernovas are involved in
the lives of stars. 1543 C.E. In Poland, Copernicus publishes his heliocentric theory. This event is important as it
helped us understand our place
in the universe. A world where
we think we are the center of
the universe feels very hard
to imagine. 1582 C.E. In Italy, Pope Gregory XIII
introduces the Gregorian
calender. This is important as it introduced
the calendar that we still use today.
While other calendars were
put out of use, this one stood
the test of time. 1609 C.E. In Italy, Galileo uses the
telescope for astronomical
purposes. This is important because it gave us a
way to look closely at the stars.
Imagine if the telescope was never
used for astronomy. 1656 A.D. In the Netherlands, Huygens
discovers Saturn's rings and
Titan. This event is important as it
introduced us to two very important
astronomical objects. It helped us
to better understand our solar
system and universe. 1659 C.E. In the Netherlands, Huygens
finds markings on Mars. This event is important because
it furthered our understanding of
Mars. Mars could be key to
understanding the
universe. 1668 C.E. In England, Newton builds
the first reflecting telescope. This event is important as it
improved the telescope. The
reflecting telescope helped us look
more closely at the stars and
planets. 1675 C.E. In Paris, Ole Romer measures
the speed of light. This event is important as knowing
the speed of light is very important
in space travel. It helps us to
understand the distances
between stars and planets. 1801 C.E. In Italy, Piazzi discovers
asteroids. This event is important because
it was when we learned of
another astronomical body.
Asteroids could be a threat, or
very helpful to us. 1846 C.E. In Germany, Galle
discovers Neptune. This event is important as it
was when we discovered a new
planet. We now better
understood the size of our
solar system. 1877 C.E. In the United States, Hall
discovers the moons of Mars. This event is important as it gave
us more knowledge of Mars.
Also, Mars is a planet which could
hold many secrets. References Massachusetts Institute of Technology (2011) Astronomy throughout History
