A View From Pluto
Digital work
Charon in the sky, behind a thin bluish haze, as seen from a reddish tholin plain of Pluto. Some areas are covered by glaciers of nitrogen and methane ice and the distant hills are made of water ice.

Caronte en el cielo, tras una delgada neblina azulada, visto desde una rojiza llanura de tolinas de Plutón. Algunas áreas aparecen cubiertas por glaciares de hielo de metano y nitrógeno y las colinas distantes son de hielo de agua.
Earthlight on the Moon
Digital Work
The bluish light of a splendid full Earth illuminates the surface of the Moon during its long night. Earthlight is brighter than the moonlight due to the larger size and higher albedo of our planet. A full Earth as seen from the Moon is about 45 times brighter than the full Moon is as seen from Earth.
Luz de la Tierra sobre la Luna. Obra digital.
La luz azulada de una espléndida Tierra llena ilumina la superficie de la Luna durante su larga noche. La luz reflejada por la Tierra es más brillante que la luz lunar debido al mayor tamaño y al albedo más alto de nuestro planeta. Una Tierra llena vista desde la Luna es aproximadamente 45 veces más brillante que la Luna llena que vemos desde la Tierra.
Ocean Planet
Digital work
An ocean planet not only has its entire surface covered by water; much of its mass and volume is water. Our planet, Earth, has 71% of its surface covered by oceans. But water represents only 0.05% of the planetary mass. We live on a rocky planet with a thin ocean that has a maximum depth of just over 10 kilometers. On an ocean planet the depths are abysmal, hundreds or even thousands of kilometers. At the bottom the water is so compressed that it solidifies and crystallizes, forming exotic species of ice, such as ice VII.
In this artwork we can see an ocean planet with a large extrasolar moon. The atmosphere is dense and saturated with water vapor and there is a persistent mist on the surface of the sea. All this causes an important greenhouse effect.
Planeta Océano. Obra digital.
Un planeta océano no sólo tiene toda su superficie cubierta por agua. Además, gran parte de su masa y su volumen es agua. Nuestro planeta, la Tierra, tiene el 71 % de su superficie cubierta por océanos. Pero el agua representa tan sólo el 0,05% de la masa planetaria. Vivimos en un planeta rocoso con un delgado océano que tiene una profundidad máxima de poco más de 10 kilómetros. En un planeta océano las profundidades son abismales, de cientos o incluso miles de kilómetros. En el fondo el agua está tan comprimida que se solidifica y cristaliza, formándose especies exóticas de hielo, como el hielo VII.
En la ilustración vemos un planeta océano con una gran luna extrasolar. La atmósfera es densa y saturada de vapor de agua y hay una niebla persistente sobre la superficie del mar. Todo ello provoca un importante efecto invernadero.
Under the light of three suns
Digital work
Gliese 667 is a triple-star system located about 24 light years from us. Orbiting within the habitable zone of one of them, the red dwarf Gliese 667C, is the planet Gliese 667Cc, a super-Earth with a mass 3.8 times greater than that of the Earth. It is probably a rocky planet that could also have oceans and atmosphere. In the sky its mother star shines with an intense reddish light and has a splendid apparent size of 1.25º, almost two and a half times the Sun seen from Earth. The other two stars of the system, Gliese 667A and Gliese 667B are K-type main-sequence stars and their powerful brightness are always visible.
Bajo la luz de tres soles. Obra digital.
Gliese 667 es un sistema triple de estrellas situado a unos 24 años luz de nosotros. Orbitando dentro de la zona de habitabilidad de una de ellas, la enana roja Gliese 667C, se halla el planeta Gliese 667Cc, una supertierra con una masa 3,8 veces mayor que la de la Tierra. Es probablemente un planeta rocoso que podría tener también océanos y atmósfera. En el cielo su estrella madre brilla con una intensa luz rojiza y tiene un espléndido tamaño aparente de 1,25º, casi dos veces y media el Sol visto desde la Tierra. Las otras dos estrellas del sistema, Gliese 667A y Gliese 667B son enanas naranjas de tipo espectral K y sus potentes destellos son siempre visibles.
Children of a minor Sun
Digital work
This is my first approach to the field of extrasolar planets.
Of the 7 planets forming the TRAPPIST-1 system, it may be TRAPPIST-1e that has Earth-like environmental conditions: water oceans, emerged lands, atmosphere and temperatures compatible with life. But like its companions, this planet is tidally locked, so the conditions previously described would only be found on the side that always looks at its star, TRAPPIST-1, a red ultracool dwarf star (M type) with a size slightly larger than the planet Jupiter. Here everything is illuminated by an exclusively red or orange light. At the same time the dark side of the planet will probably be a frozen world with a perpetual night.
Hijos de un Sol menor. Obra digital
Esta es mi primera aproximación al tema de los planetas extrasolares.
De los siete planetas que componen el sistema TRAPPIST-1, tal vez sea TRAPPIST-1e el que reúna unas condiciones ambientales más parecidas a la Tierra: Océanos de agua, tierras emergidas, atmósfera y temperaturas compatibles con la vida. Pero al igual que sus compañeros, el planeta presenta acoplamiento de marea por lo que las condiciones descritas sólo se darían en la cara que mira a su estrella, TRAPPIST-1, una enana roja ultrafría (de tipo espectral M), con un tamaño algo superior al de Júpiter. Su luz ilumina de un rojo anaranjado intenso el cielo y el paisaje del planeta, mientras que en el lado oscuro reina una noche perpetua sobre un mundo congelado.
A serene night on Europa
Digital work
The Sun is situated below the horizon and the only sources of light that illuminate the smooth and white surface of Europa at this time are Jupiter and Io. The light appears to be somewhat bluish to the human eye, as it happens here on Earth with the moonlight, due to the Purkinje effect: When the luminance level is reduced, our vision changes progressively from photopic (cone cells, full color) to mesopic and finally scotopic (rod cells, black and white) and the last colors we perceive are those of short wavelength. The surface of Europa is very reflective. It has an albedo of 0.64, one of the highest in the Solar System.
Una noche serena en Europa. Obra digital.
El Sol está situado por debajo del horizonte y las únicas fuentes de luz que iluminan ahora la suave y blanca superficie de Europa son Júpiter e Io. La tenue luz del paisaje aparenta ser un tanto azulada al ojo humano, tal y como sucede aquí en la Tierra con la luz de la Luna. Es debido al efecto Purkinje: Cuando el nivel de luminancia disminuye nuestro modo de visión pasa progresivamente de fotópico (visión a todo color por conos) a mesópico y finalmente escotópico (visión por bastoncillos en blanco y negro). Los últimos colores que percibimos son los de longitud de onda corta.
La superficie de Europa es muy reflectante. Tiene un albedo de 0.64, uno de los más altos del Sistema Solar.
And Mars got its ring...
Digital work
This is my personal view of the future Martian ring. This image would fit well on a dusty dawn at a latitude of about 20ºN during a Martian equinox.
Phobos is moving closer to Mars every year, meaning the planet's gravitional pull on the satellite is increasing. Some scientists have theorized that Phobos will eventually collide with Mars, but the new research suggests that the small moon may not last that long. After simulating the stresses caused by the tidal pull of Mars some researchers have found that the moon would break up over the course of 20 million to 40 million years, forming a ring of debris around the planet. WOW!
Earth as seen from Mars
Digital work
Based on the images taken by Mars Curiosity Rover on January 31, 2014. From Mars our planet is a bright morning or evening "star", it appears in the west after sunset or in the east before dawn. Very similar to Venus in our sky with a magnitude of -2,5.
La Tierra vista desde Marte. Obra digital.
Ilustración inspirada en las imágenes tomadas por el Mars Curiosity Rover el 31 de enero de 2014. Desde Marte nuestro planeta es como una brillante estrella del crepúsculo matutino o vespertino, aparece en el oeste tras la puesta de Sol o en el este antes del amanecer. Muy similar a Venus en nuestro cielo, con una magnitud de -2,5.
Mars as seen from Phobos
Digital work
Separated by a short distance of 9,380 kilometers, from Phobos Mars is immense. The angular size of 40º is 80 times our Moon as seen from Earth.

Separados por la corta distancia de 9.380 kilómetros, desde Fobos Marte se ve inmenso. Con un tamaño angular de 40º es 80 veces nuestra Luna vista desde la Tierra.
Phobos and Deimos in the sky of Mars
Digital work
Phobos moves very quickly in the sky of Mars. From its dawn in the west to its setting in the east, the satellite crosses the Martian sky in only 4 hours and 15 minutes. The angular size is about 0.20 °, one-third the size of the Moon in our sky. Deimos is visible with a size of 2.5 arcminutes, similar to Venus seen from Earth.
Callisto
Digital work
The ancient surface of Callisto is one of the most heavily cratered in the Solar System. A surface made of cratered plains, light plains, bright and dark smooth plains... a contrast of darkness and brightness. Callisto also hides a treasure: A salty ocean 50-200 km deep beneath its surface. Callisto's surface has an averige albedo of about 20%, but small patches of pure water ice, water frost deposits, with an albedo as high as 80% are found on the surface, surrounded by much darker areas. They are located on elevated surface features as crater rims, scarps and ridges.
In the sky, Jupiter with a size of 4º, eight times our Moon seen from Earth. Here it is accompanied by one of its inner moons, Europa.
