'Unsterblichkeit' (immortality) is made up of three parts: the prefix 'un-' (not), the stem 'sterb-' (from 'sterben' (to die)), and the endings '-lich' and '-keit', which form a noun. So it describes the state of not being mortal.
Die Alchemisten träumten davon, den Schlüssel zur Unsterblichkeit zu finden.
The alchemists dreamed of finding the key to immortality.
As an abstract noun, 'Unsterblichkeit' (immortality) is usually used in the singular and often without an article when referring to the general concept. The article is used when a specific kind is meant, e.g. 'die Unsterblichkeit der Seele' (the immortality of the soul).
Viele Menschen glauben an eine Form von Unsterblichkeit nach dem Tod.
Many people believe in a form of immortality after death.
In the literal sense of eternal life, 'Unsterblichkeit' (immortality) is often combined with verbs such as 'erlangen' (to attain), 'suchen' (to seek), or 'verleihen' (to grant).
Der Legende nach verleiht der Göttertrank Unsterblichkeit.
According to legend, the drink of the gods grants immortality.
The figurative meaning 'eternal fame' can be recognized from context. When it is about artists, scientists, their works, or great deeds, it usually means fame, not eternal life.
Durch ihre Entdeckungen hat sich die Forscherin Unsterblichkeit gesichert.
Through her discoveries, the researcher secured immortality for herself.
eternity
'die Ewigkeit' and 'die Unsterblichkeit' both have to do with something that does not end. 'Ewigkeit' mainly describes a time or duration without end. 'Unsterblichkeit', on the other hand, describes a state: someone lives forever or is remembered after death through fame. Learners may confuse the words because both sound connected to 'ewig' (eternal). The simple rule is: 'Ewigkeit' is endless time; 'Unsterblichkeit' is eternal life or a person's lasting fame.
