Our understanding of the universe has changed a lot over time!
Ptolemy
He improved on Aristotle's theory which was that the earth was the center of the universe also known as geocentric.
Nicolaus Copernicus
Copernicus had a theory that the sun was the center of our solar system. This is also known as heliocentric.
Tycho Brahe
His work supported the idea that the Earth orbited the sun.
Brahe hired Kepler, another astronomer to work with him.
How has our understanding of the universe changed over time?
Aristotle
Johannes Kepler
Galileo
Isaac Newton
Edmund Halley
Edwin Hubble
By Isamilla & Nelleke
The Hubble space telescope was named after Edwin Hubble.
He had three laws of motion.
He hypothosized that the nebulae were their own galaxies.
<span>He imagined the earth at the </span>
center of the universe with the sun, the moon, the stars and the planets orbiting it in perfect circles.
Newton put Kepler and Galileo's ideas together and discovered that the reason that things fall on the ground is the same reason that planets orbit around the sun.
He made a telescope that could magnify
up to 30 times.
<span>He discovered that Copernicus' theory </span>
was true. "We're not the center of the universe."
He found out that the planets orbit the
sun in ellipses (oval shapes).
He explained how the tides were made by the moon.
He figured out that the speed of the planets depend on the sun.
Halley discovered a comet. It was discovered in 1705. It will come around again in 2061
The comet Halley comes every 75 - 76 years

White-headed woodpeckers are adapted to have strong beaks that can break into tree trunks to find bugs and can also open pine cones to get at the seeds. White-headed woodpeckers are best adapted to living in the biome of the<u> temperate rain forest</u>
Explanation:
- The white-headed woodpecker is a non-migratory woodpecker that resides in pine forests of the mountains of western North America. It has a black body and white head. It has white primary feathers that form a crescent in flight.
- White-headed Woodpeckers feed heavily on large pine seeds, and are most associated with old-growth ponderosa pine and sugar pine forests. They also often use recently burned areas.
- The white-headed woodpecker is a non-migratory woodpecker that resides in pine forests of the mountains of western North America.
- Temperate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive heavy rainfall.
- White-headed woodpeckers are adapted to have strong beaks that can break into tree trunks to find bugs and can also open pine cones to get at the seeds.
- White-headed woodpeckers are best adapted to living in the biome tundra temperate rain forest savanna desert
- The white-headed woodpecker is a non-migratory woodpecker that also resides in pine forests of the mountains of western North America.
