128 páginas | Tapa blanda

La historia del origen y evolución del universo explicada de forma clara y concisa por uno de los investigadores más destacados en el campo de la astronomía.

El reconocido astrónomo chileno Mario Hamuy ofrece en su nuevo libro las herramientas indispensables para comprender de forma sencilla los temas centrales de la astronomía contemporánea y uno de los mayores hitos de la cosmología: la expansión acelerada del universo.

Lleva al lector por un viaje fascinante: exoplanetas, nebulosas planetarias, supernovas, materia oscura y agujeros negros, y explica cuestiones tan fundamentales como de qué forma se miden las distancias entre planetas, qué pasó después del Big Bang o, por ejemplo, quién es Edwin Hubble. Todo esto acompañado de anécdotas personales del autor e imágenes que ayudan a representar estos temas.

Un libro para ponerse al día en una de las ciencias que más pueden hablarnos sobre nuestro futuro como especie.

Set name: Adult Tube - 3.4oz.
I really like this Grass-Fed Tallow Mineral Sunscreen. It feels natural on the skin and doesn’t cause irritation. The texture is smooth, easy to apply, and gives good sun protection. I also like that it uses mineral ingredients and doesn’t have a strong chemical smell. It leaves a slight white cast at first, but it blends in after a few minutes. Great option for people with sensitive skin

No burn after a week on Lake Havasu
Set name: Adult Tube - 3.4oz.
A week on Lake Havasu in the Arizona sun without any burning. The sunscreen goes on smoothly and works in quickly. No difficulty getting the white tint to go away. No odd smell. No sticky feeling. For reference I am of Scandinavian decent with fair skin and very blonde hair.

easy to blend AND no white cast? UNREAL but true
Set name: Adult Tube - 3.4oz.
i was initially drawn to this sunscreen because i saw it had a great EWG score (1). i hesitated at first because of the price but very happy i went through with my purchase. i have medium to tan combination skin and this sunscreen was very easy to blend onto my face, given that it has a moisturizer like texture. and the best part? NO WHITE CAST. only removing a star because it is still pricey especially for the size which is why I've been limiting its use to my face lol

Great for sensitive skin!
Set name: Adult Tube - 3.4oz.
Great product! With sensitive skin this is wonderful without the white cast, grainy feel, and chemicals! Used on my kids and myself during softball days with no burns or rashes!! We always have a hard time finding good sunscreen that I don’t stress about! This is one I will buy again! Highly recommend!

The best!! So glad I took a chance and ordered
Set name: Adult Tube - 3.4oz.
This is the best natural sunscreen I have ever used and I am so excited to find one that is tallow-based and has none of the usual offenders. It goes on like a dream, leaves no white cast, and is not greasy or thick. It’s just perfect and I will always order and keep some on hand. Thank you!!
