The End!!

1930 A.D

Clyde Tombaugh discovers Pluto.

Significance: 1st planet to go from a planet to a dwarf planet.

1608 A.D.

1843 A.D

Hans Lippershey invented the telescope.

Henry Heinrich Schwabe describes the Sunspot Cycle.

Significance: 1st person to describe the Sunspot Cycle.

800 B.C

280 B.C

Significance

The Vestini Tribe put The Stones of Fossa in place. Located in present day Italy.

The telescope was very useful and essential for expanding our knowledge of the cosmos.

Aristarchus suggests Earth revolves around the Sun, and provides the first estimation between the Earth and the Sun.

Significance

They had probably noticed the sun rises in the East and sets in the West. If they had believed in an afterlife, they probably hoped human souls would follow this path as well, making these stones.

Significance

He created the astronomical unit, a measurement of the distance between the Earth and the Sun. This was also used to measure the distances between the Sun and the other planets.

1,700 B.C

240 B.C.

Eratosthenes measures the circumference of the Earth with surprising accuracy.

Bronze was introduced, located in Britain

Significance

Significance: He had used the shadow given from the Sun to measure the circumference of the Earth, being the first closest and most accurate measurement.

1916 A.D.

Significance

Both elements used to create bronze are found in stars when they die.

1781 A.D.

Albert Einstein introduces his Theory of General Relativity.

Hershel discovers Uranus

Significance

The Theory of General Relativity explains that gravitational forces are equivalent to forces caused by acceleration. It is also the basis of modern-day physics.

Significance

Uranus is the first planet to be discovered with the telescope. It is also the first time our knowledge of the solar system expands.

1572 A.D.

Tycho Brahe discovers a supernova in the constellation of Cassiopeia.

2,000 B.C

First solar lunar calendars, located in Egypt and

Mesopotamia.

Significance

He discovered a supernova without using a telescope.

Significance

Significance: Used stars, the Moon, and the Sun to make the calendars.

1923 A.D

Hubble shows that galaxies exist outside the Milky Way Galaxy. Located in the U.S.A

14th-16th Century A.D.

Significance: Developed the idea of expanding universe.

30,000 BC

The Renaissance occurred in Europe.

1801 A.D

Asian hunter-gatherers had crossed over the frozen Bering Strait, becoming the first humans in North America.

Significance

They had probably used the stars to navigate across the Bering Strait.

During the Renaissance, a great advance in astronomy had occurred. Also, the scientific method was created, allowing us to question our knowledge of the cosmos even further.

Also, the scientific method was created, allowing us to question our knowledge of the cosmos even further.

Piazzi discovers the 1st asteroid, Ceres. Located in Italy.

Significance

1st asteroid to be discovered. Largest asteroid in the asteroid belt.

2012 A.D.

The James Webb Space Telescope (JWST) is announced.

Significance: This telescope works best with infrared wavelengths, allowing us to find the first stars and galaxies of the universe, as well as extraterrestrial life on other planets.
