Star trails
A window should face south for gardening where the plants get the most light.
Goes east to west looking souther direction.
…
Sun goes clockwise if.sr’fgls;aflmg’s;akfmhs;kfg
Polaris - doesnt move very much from our perspective because the Earth’s north pole pulls diercty towards it. All the other stars will look like it’s moving around it
Space has a lot of circular stuff
Geometry
Look North it looks counterclockwise
Look south it looks clockwise
Constellations
Bunch of artwork and mythologies connected to constellations
(Orion) depicted sometimes with a sheild and a sword bow and arrow hunted Orions belt
Worst game of connect the dots bruh
Lepus Hair that he’s hunting
Canis Major and Canis Minor are the dogs Major the big dog Minor the small dog
The sky is complicated so that was a way to make sense of it. So interesting that’s connected to psychology.
Scorpio is seen by Orion
Some constellations that appear in some parts of the world that you will never see in ither parts
Austalia doesnt have the little dipper
Monoseros - more modern to fill the gap means. A unicorn
88 constellation fill the entire sky
Celestial Sphere
- Stars at different distances all appear to lie on the celestial sphere
- The 88 official constellations cover the entire celestial sphere
The sun cuts through the zodiac signs
Sun signs
Your sign serves at a function of where the sun is at at a given time
It used to be correct but not anymore
The sun
The sun during that month is right in front of that constallelation
If you could block out the sun today and look at all the stars, you wouldve seen aquarius (Feburary 10 today)
Things have shifted for the last years. If you’re aquarious you’re actually capricorn
RYAN WOULD LOVE THIS INFO LOL
Perception of the Equanonsis
Earth North’s Pole wobbles
A few thousand years ago the North Star was not Polarius it was…Thuben or fooben
Egyptions believed that’s where your souls go when you die
Then its polaris
It will eventually be Aduv
Zodiac
CIrcle of Animals. We’re a month behind. I think that means I’m Aquarius if Aquarias is right before Pisces
Ecliptic
The apparent path through the celestial sphere
23 and a half is the axial tilt
Difference betwreen line corespioinds ecliptic plane and line that corresponds with equator. As above As below
More tilt, more distance, no tilt, no distance
Sun directions
Equanox only directly east and west sun
Rise slightly south of east and slighly south oferst durinhg winter
During summer slightly north of east and slightly north of rest’
Right no wFeburary kinda winter
Somehwere around March 21 is Equanox
My proffessor is EKKo?
DUe to suns orbit sun feb to march sun does the opposite moves to the left»]]??
During teh day the sun moves to the right bc of the rotation not the
Everyday it moves a little less than one degree. 360 degrees a circle one year has 35 days
RIGH
WINTER MYSTERY AND
You get less daylught during the summer
Where the sun is lowest in the sky the Arch is smaller it’s not in the sky for as long its lower down theres also lower solar radiation which is also a factor that causes our seasons
Ohhhhhhh
During summer its higher up so its in the sky a lot
23 and a half degree mark limitation?
longer
Eclipse
Moon betweenn…. And sun its lunar
Moon line up where the ecli….. you get an eclipse
Milky Way
A band of light making a circle around the celestial sphere. Our view into the plane of our galaxy
The Eye cant view itself
Alt
Altitude numbers correspond to latitude
IM SO SICK OF THAT ATTITUDE
NObody bE me on that latitude
If 60/90 degress latitude, means north star /directly overhead
Zenith
Horizon
Always 90 degrees away from Zenith
Tells you what you can see from the sky
IF youre in the southern hemsephere you see different things than the northern hemisphere. Austrailia doesnt see the little dipper. Because it doesnt go past their horizon or something. It has to go below our horizon for someone below us to see us
Angular Measurement
One degree covered by a single finger
Full circle 360
1 degree =-17.222 °C 60 Archminute
Divide Archminute in 60 = Archseconds
Invented for more precision
3,600 parts one of those parts from your finger is an archsecond
Angular Size and Distance <— Know
Data = S/R or Data = S over R
Ratio of Archlength divided by raidus
If oyu know the distance away it is wihch corresponds to radiys and you know where the angle then you can figure our the last varuable which is the arch length this arch length corresponds to the physcial size
The sky qual to S/R \
Fata .. physiocal object of the moon divded by the distance
S arch length around..l;lrgka[spjgsie
…
Know diameter of the moon and distnace
Physical size divided by radius or dsitance would be equal to your angle
Distance is your ….s;lr’k radius?
Conversions from radius to degrees’S or R answer in term of radiants
Dgerees like finger multiply ratio of 360 for every two pi radiants.
The asnwer should be .5 one half of a degree cuz half your finger can cover the moon.
Stars Rise and Set
Earth rotates from west to east, so stars appear to circle from east to west.
Constillation latitudde would be the same but longitude you may not be able to see tgen atnight
Opprtunity to see the same stars but sun ….
