Transcript of astronomy project
We will never stop discovering whats out there but , just keep walking down that path. Although it may be tough the discovery only adds to our knowledge to keep on going.
A Journey Through Astronomy
The Newgrange tomb is built.
This demonstrated that the community knew the movement of the sun at a very early time.
Newgrange was built during the New Stone Age by a farming community that prospered on the rich lands of the Boyne Valley.
In England the main stones of the Stonehenge were put into place.
How the stones were put in place is only part of the wonderful mystery. Some scientist claim they were aligned within hundredths of an inch to reflect the relationships of the Cosmos.
It has been suggested that it developed over hundreds if not thousands of years starting with a few wooden poles that aligned the rising and falling of the sun each year.
In Mesopotamia the first lunar calendars were put into use.These calendars consist of of 12 lunar months.Also known as So-lunar Calendars they plotted the days according to the movement and rotation of the moon.
develops the 1st accurate star map and star catalog with over 850 of the brightest stars.
In China the chinese astronomers observe a super nova in Tarus.
The egyptians start to use sundials
The sundials told hours and fractions of a second.
They use the position of the Sun in the sky to tell time from how the sun "moves".
You can tell the time by looking at the shadow cast by the Sun as it shines on the pointer of a sundial. The proper name for the pointer is a Gnomon ( 'nom-on')
1609 A. D
Galileo use the telescope for astronomical purposes.
He discovers 4 Jovian moons, our moons craters, and our home the Milky Way Galaxy.
Chinese use telescopes for the sky. This is important because the chinese used telescopes to find out
where and how sunspots are found and how they are formed.
Newgrange was planned out and built to face sunrise at the midwinter mark only one day of the year showing that people here new the movement of the sun an used it to their advantage.
This was important because he finally discovered more elements that make up the the universe and that other planets could have moons as well.
Frederick William Herschel discovered Uranus.
He also discovered that it has a spin axis , this produces unusual seasons and unique magnetic and electric field structures.
Cassini discovers that Saturn's rings are split into two parts so that today they are called,"Cassini Division".
The discovery of the "Doppler Effect" was discovered by Austrian physicist and mathematician,
The Hubble Space Telescope was put into space from the Space Shuttle Discovery.
This was the most important exploration tool in the last 2 decades for exploring the depth of the unknown space.
It is important because we found out where some of the rings of Saturn are located and got a better understanding of the planet just by observing it.
The Space Shuttle
Endeavor makes a
map of the Earth.
This effect shows us a better understanding of how sound waves
and frequencies change from different directions in Earth and in space.
Doppler Effect 1842 A.D
This was really exciting because we found a way to map the surface of a planet while just orbiting around it.
Pluto is no longer a planet, according to a new definition of the term voted on by astronomers it is now a dwarf planet, because it does not dominate the neighborhood around its orbit. Charon(Pluto's moon) is half the size of Pluto and orbits along with it; the eight true planets are all far larger than their moons.
We found the first visual proof black holes.
This is important because now we know that they exist and are not a theory or idea.
Gan De made some of the first detailed observations of Jupiter in recorded history. He described the planet as ,"very large and bright". In one of his observations on Jupiter, he reported a ,"small reddish star" next to Jupiter.
This was important because we started to realize there is something out there other than planets and stars.
THANK YOU FOR YOUR TIME
THANK YOU FOR YOUR TIME!
This event was very important because it was the first accounted super nova seen with the naked eye.The discovery of this super nova made them start to wonder.(Left them hanging)
