light, which for a millennia has been the only way we can observe the universe
Astronomers learn about the universe in 4 ways : - Answers - 1: Ordinary matter
2: Neutrinos
3: Gravitational waves
4: Light
ordinary matter - Answers - Meteors, cosmic rays, lunar rocks
Neutrinos - Answers - essentially mass less particles that are created at suns core and
may let us study the core
Gravitational waves - Answers - Ripples that travel outward from gravitational sources at
the speed of light.
,light - Answers - Main way to discover.
- Radio waves, gamma rays etc.
The "fixed" stars - Answers - Maintain fixed patterns among themselves, define
constellations
- Stars do not move individually, they are so remote that the patterns don't change for
many of thousands of years.
divinal motion - Answers - Daily motions of the stars and other bodies, produced by
earths rotation. W-E
- Whole pattern moves around us once a day/ universe spinning.
Proof; star trails
Star Trails - Answers - Long exposure photos of stars as they move across the sky,
used to capture the apparent motion of stars in the night sky
The Pole Star ...? - Answers - Stays unchanging location due north
Are the southern seen by us? - Answers - No, The southern stars are unseen by us
because we are north.
Southern stars rise in the? - Answers - South
Northern stars rise in the ? - Answers - North

The Stonehenge - Answers - a structure found by scientist in England is believed to
have been built in the Neolithic Age and Bronze Age
-Stone circles were brought from Malborough and dragged across country
Bluestonehenge - Answers - Were brought from Wales and were presumably floated on
rafts along the coast
- Believed to have astronomical connection
-had fallen
Aubry holes - Answers - Ring of 56 chalk pits at Stonehenge
- Could have been eclipse predictors
petroglyph - Answers - a rock carving made by people
, The Egyptian Pyramids - Answers - burial tombs for pharaohs and their bodies were
mummified
- Made of stones by well-paid and dedicated labourers who did it out of respect
The Egyptian pyramids connection to astronomy - Answers - The pyramids were divided
in sections of the king, queen, and so on.
-in the queens chamber there was a tiny vent hole that when looked through, would face
the star Sirius.
-In the king chambers has the same but faced the Orion belt
Lunar Calendar - Answers - a calendar system based on the moon's rotation around the
earth
- Would be used to know when the month would pass
What are the two big importance of Polaris? - Answers - 1. Always in the north
-Use the Big Dipper to find Polaris
-It is the home star
-Helps with navigations
2. Columbus used this form of navigation when sailing
The sun - Answers - A typical star that is the source of light and heat for the planets in
the solar system.
-We orbit the sun
- The sun behaves like a southern star. it appears low in the southern sky, which is why
we have changes of seasons and hours
The apparent motion of the sun - Answers - the Sun appears to rise in the eastern part
of the sky and moves up in the south sky to its highest point in the sky at noon
-The earth spins axis is every 24 hours which is why we see a sun rise and a sun set
how long does a complete orbit takes? (earth) - Answers - 1 year
How are seasons created? - Answers - The tilt of the Earth's axis.
We are closer to the sun half a year and further when winter
the oritical point - Answers - The sun during winter is very low in the sky and asks like a
southern star which is why its colder.
The sun during summer is higher in the sky and acts like a northern star which is why its
warmer
Special dates to remember - Answers - June 21: the sun ends its steady climb
northward and will start moving southward again. known as summer soliscs
Dec 21: the sun ends its steady drift southward and will start moving north again -
Winter
