This is my submission for the Final Exam of Astronomy-301 in Hogwarts is Here.

1. Orientation-Astronomy Year 3
This orientation is targeted for those in Year 2 of
Astronomy.
Done by:- Prof. Turing and team

2. Introduction
This course is taught by Prof. Brad Turing
In Year 3, we will delve deeper into the studies of the Cosmos
We will learn about some magical concepts in Astronomy
We will also begin learning Muggle Astronomy
The Midterms are held in Week 5 and the Finals are held in
Week 9
Those interested in pursuing a career in Astronomy can join the
Cosmology Career Path in Year 4.
For further information, contact Brad Turing (Prof.) or Misty
Turing (Head Girl)

3. Syllabus for Year 3
The following topics will be covered in this year:-
Shapley-Curtis Debate
Types of Galaxies
M-Energy Theory
Galactic Distance and Ancient Light
Formation of the Moon(and Midterm)
Tully-Fisher Method
Active Galaxies
Radio Astronomy
Cosmic Background Radiation(and Final)

4. L.1. Shapley-Curtis Debate
Shapley-Curtis Era
Shapley Curtis Debate
Cepheids

5. L.1 Shapley-Curtis Debate
The 5 main points in the Shapley-Curtis Debate were the Size
of the Milky Way(Shapley), Distribution of Nebulae in the
Sky(Curtis), Observations of Novae(Shapley), Brightness and
Spectra of the Nebulae(Curtis) and Rotation of
Nebulae(Curtis).
Cepheids are stars that regularly change their brightness over
periods between one day and hundreds of days. They are classified
as super giants.
Occulting is to conceal an apparently smaller celestial body from
view by passing or being in front of it.

6. L.2. Types of Galaxies
Spiral
Barred Spiral
Elliptical
Irregular
Lenticular

7. L.2. Types of Galaxies
In this lesson, we will be learning about the different types of
Galaxies. They are:-
Spiral
Barred Spiral
Elliptical
Irregular
Lenticular
We will also be learning about the Hubble Sequence.

8. L.3 M-Energy Theory
M-Energy
How is it formed?

9. L.3 M-Energy Theory
M-Energy is recognized by Muggle Astronomers as Hawking
Radiation.
The energy in which each Witch and Wizard manipulates is
called M-Energy.
Created from a Black Hole.
The process-1. The Breakdown
2. Emerging from the beast
There may be variances in the amount of M-Energy produced
depending upon the magical ability of that person.

10. L.4 Galactic Distance and
Ancient Light
Ancient Light and Lightworkers’ Robes
Dark Magic and Heavy Amulets
Standard Candles

11. L.4 Galactic Distance and
Ancient Light
Ancient Light is a key component needed to craft magically
regenerative clothing
Lightworkers’ robes are the best example for regenerative clothing-they
heal a good, conscious person who wears it.
But, if an evil person wears it, it will burn them.
Galaxy clusters are a source of Dark Matter.
Dark Matter is commonly found in everyday life as jewelry.
The first attempt and making accurate estimates of the age of ancient
light came from the use of standard candles.
Using standard candles, we can determine the distance of astronomical
objects from Earth by comparing it to the brightness of objects that
are a known distance from the Earth.

12. L.5.Formation of the Moon
This lesson also has the Mid-Term Examinations for
Year 3 Astronomy

13. L.5. Formation of the Moon
There are three main theories about the formation of the Moon.
They are:-
The ‘sister’ or co-formation theory
The ‘capture’ theory
The ‘daughter’ or fission theory
The Mid-Term Examinations will be held in this week.
It will have questions from all the five lessons done so far.

14. L.6. Tully-Fisher Method
Limitations of a Standard Candle

15. L.6. Tully-Fisher Method
In the 1970’s, two Muggles by the names of R. Brent Tully
and J. Richard Fisher developed a new method to extend the
range of distances that we can measure from Earth.
This method is now known as the Tully-Fisher method.
The Tully-Fisher method can be used to measure the distance of
spiral galaxies from Earth.

16. L.7. Active Galaxies
Seyfert Galaxies
Radio Galaxies
Quasars

17. L.7. Active Galaxies
In 1943, Carl Seyfert, an American optical astronomer studying
spiral galaxies from Mount Wilson Observatory, discovered
Seyfert galaxies.
 They are a class of astronomical objects whose properties lie
between those of normal galaxies and those of the most energetic
active galaxies known.
Radio galaxies are active galaxies that emit large amounts of
energy in the radio portion of the electromagnetic spectrum.

18. L.8. Radio Astronomy

19. L.8. Radio Astronomy
Radio Astronomers study radio waves from space using sensitive
antennas and receivers which give them precise information about
what an astronomical object is and where it is in our night sky.
They can convert these transmissions to sound using simple
analog techniques.
Muggle influences are quite a lot in this particular branch

20. L.9. Cosmic Background
Radiation

21. L.9. Cosmic Background Radiation
Even though we cannot see some major astronomical events in
person, we are able to infer what has happened based on the clues
that these events leave behind.
The best example is the Big Bang Theory.
There is also another aspect of the cosmic background radiation.
This portion of the cosmic background radiation is called the
cosmic magical background radiation.
