4. Introduction
Stars evolve along million years.
• Birth of the stars
• Stages:
- Principal sequence
- Maturity
- Old age
*Die
*Become into a red giant

5. Nebula
• Definition: it is a giant cloud with different
forms.
• Composition: hydrogen, helium and cosmic
dust.
• Localization: interstellar media.
• Purpose: it is the place where stars born.

6. Types
-Dark nebula: a cloud of dust
and cold gas that doesn’t
emit visible light.
-Diffuse reflection
nebula: it is made up of
hydrogen and blue dust.

7. -Emission nebula: it is the
most common type of visible
nebula, it emits light.
Hydrogen atoms excite
ultraviolet light to produce
energy.
-Planetary nebula: it is
made off gas balls and
fluorescent matter. It
emits gas from dead
stars stars.

8. -Reflection nebula: it is a cloud of dust that
reflects light from other stars but it doesn’t
emit enough light for the nebula to illuminate.

9. Main sequence
• Composition: plasma, hydrogen and helium.

10. Main sequence
• Creation: it is created from the collapse of a
stellar nebula.

11. RED GIANT
• Definition: it is a enormous star with low
mass.

12. RED GIANT
• Composition: Hydrogen, Helium.

13. RED GIANT
• Creation.

14. PLANETARY NEBULA
• Definition: last phase of the life of a star.
Discovered 200 years ago

16. PLANETRAY NEBULA
SPHERICAL BIPOLAR RING FINGER
QUADRUPOLAR IRREGULAR

17. MASIVE STAR
• Definition: is a star with a higher quantity of
mass.

18. MASIVE STAR
• Compostition: Hydrogen, helium.

19. MASIVE STAR
• Creation: it is formed from the phase in which
helium is burned.

20. RED SUPERGIANT
• Definition: is an enormous star with low mass

21. RED SUPERGIANT
• Composition: Hydrogen, helium, Carbon and
Iron.

22. RED SUPERGIANT
• Creation.

23. SUPERNOVA
• Definition: Stellar explosion that manifest
itself in a very remarkable way

24. SUPERNOVA
• 1975- explosion of a red gigant

25. SUPERNOVA
• 06/10/2013- First image of a supernova in its
early stages
