Nebulosas planetarias: la hermosa muerte de las estrellas
Silvia Torres y Julieta Fierro
ISBN: 9786071600721
Precio: € 8.50
En siete mil millones de años nuestro Sol se convertirá en una nebulosa planetaria y luego morirá. Las nebulosas planetarias son estrellas en su proceso final de evolución; al estudiarlas conocemos el futuro del Sol y de gran parte del universo. Si tomamos un telescopio pequeño y apuntamos al cielo, el objeto celeste más hermoso con el que nos toparemos seguramente será una nebulosa planetaria. Silvia Torres y Julieta Fierro nos relatan la manera en que los astrónomos han logrado desentrañar las cualidades de estos cuerpos celestes.

El libro comienza por la historia. Se describe cómo William Herschel y su hermana Caroline descubrieron las nebulosas planetarias. Posteriormente, se describe la importancia de las observaciones y los instrumentos. Se dedican varios capítulos a la descripción de las estrellas y su evolución, ya que las nebulosas planetarias son estrellas en el proceso final de su existencia. Se hace especial énfasis en el estudio de los espectros, la calidad de la luz de los astros.
