Astrology is a skill that provides passive buffs to various other skills in the game similar to the 
Agility skill.
Modifiers will be unlocked as you level up your mastery in each constellation, and the buff can be upgraded by spending 
Stardust or 
Golden Stardust to level up that buff to a maximum level of 5 for Golden Stardust buffs and 8 for Stardust buffs.
Leveling Astrology involves Studying various Constellations, starting with the Deedree Constellation at level 1. Studying has a base interval of 3 seconds per action. Studying does not cost any resources and provides Astrology experience and Mastery experience for the Constellation after each action.
Each Study action also has a chance to provide Stardust, Golden Stardust, 
Abyssal Stardust, or to discover a Meteorite or Starfall.
Training Astrology is the primary way of obtaining Stardust and the only way to obtain Golden Stardust. Both are acquired at random while studying Melvor Constellations, where Stardust and Golden Stardust drops with a 5% and 2% chance per action respectively.
Stardust can also be obtained in small quantities from 
Cutting or 
Burning 
Magic Logs - see the respective pages for more information.
If the Into the Abyss Expansion is owned, Abyssal Stardust can be obtained from any Abyssal Constellations. The base rate for Abyssal Stardust is 8%.
All 3 types of Stardust can be obtained in set quantities from 
Township Tasks.
For boosts to Dust Chance or Quantity, see Astrology/Boosts.
Each Constellation starts with 6 predetermined Stars (modifiers) that are unlocked by increasing the 
Mastery Level of the Constellation. Upgrading Stars that provide standard modifiers costs Stardust, while upgrading Stars that provide unique modifiers costs Golden Stardust. The modifier starts at 0, so you need to use the appropriate type of Stardust to benefit from a Stars' modifiers.
The maximum amount of upgrades you can put into a Star modifier is determined by the type of modifier. Normal modifiers can go up to level 8, whereas unique modifiers can only go up to level 5. Each upgrade gives a linear increase to the bonus.
The first upgrade requires 10 Stardust or 50 Golden Stardust. With each upgrade, the cost of Stardust or Golden Stardust will double, resulting in the last upgrade of a star costing 1,280 Stardust or 800 Golden Stardust. Each standard modifier requires 2,550 Stardust to max out, while each unique modifier requires 1,550 Golden Stardust to max out. This results in the following total cost by expansion:
