15. JOHANNES KEPLER
• He studied the movement of the planets
• There are three rules that describe the
movement of the planets around the Sun.

16. • Primera Ley (1609): Los planetas se desplazan
alrededor del Sol describiendo órbitas elípticas,
estando el Sol situado en uno de los focos.
• Kepler nunca consiguió comprender el sentido
último de tales de leyes.
Isaac Newton (1643-1727) enunciaría su teoría de la
Gravedad y la leyde la Gravitación Universal en 1685
ofreciendo así una explicación natural de las leyes
de Kepler como consecuencia de la interacción
(atracción) gravitacional que sufren los cuerpos.

• What is it?
– It is a star.
• Is it far or close to us?.
– It is 150 million km away from us
• Is it hot or cold?
– Very hot.
• What is it made of?
– Hydrogen and helium

19. Stars
• They form when gases (hydrogen) are
pulled together by gravitational forces.
• They are so hot that they emit light and
heat.
• An enormous cloud of dust and gas, a
nebula, surrounds the stars

32. • es un telescopio que orbita en el exterior
de la atmósfera, en órbita circular
alrededor de la Tierra a 593 km sobre el
nivel del mar, con un período orbital entre
96 y 97 min. Denominado de esa forma en
honor del astrónomo Edwin Hubble, fue
puesto en órbita el 24 de abril de 1990
