Po tom ako 93. eso dostalo v Rači príprah 140tku, vezú spolu po stanicu Zohor ucelený vlak wapiek z Hanisky pri Košiciach do Rohožníka. Od Zohoru sa s ním na viackrát budú musieť potrápiť rušne radu 742.
Cántame esa canción
que el aire te susurra
en los días de bonanza.
Dime si te habla el cielo,
tú que tan cerca te hallas.
Desarropado de lujos
te mantienes ahí erguido,
callado y venturoso
por haber subsistido
a todos esos destrozos
que la humanidad ha tenido.
Callado, guardas silencio,
dejando al sol sus antojos.

Mujerzuela dice: Mi hermosa Juanina.
al fin con su vestidito de corista de las vegas!. con su sonrisa salvadora y sus gafitas de gnona BP.
Un retrato con todo el amor del mundo que hice yo y que Karim tomo.
Te adoramos.
Juanina responde: Foto tomada por don beibi Slow Cheetah y dibujo hecho por mujerzuela beibi langosta. Los quiero tontos, los extragno y que bueno que piensen en mi de vez en cuando.

Just in time for the festive season, this new Picture of the Week from the NASA/ESA Hubble Space Telescope features a glistening scene in holiday red. This image shows a small region of the well-known nebula Westerhout 5, which lies about 7000 light-years from Earth. Suffused with bright red light, this luminous image hosts a variety of interesting features, including a free-floating Evaporating Gaseous Globule (frEGG). The frEGG in this image is the small tadpole-shaped dark region in the upper centre-left. This buoyant-looking bubble is lumbered with two rather uninspiring names — [KAG2008] globule 13 and J025838.6+604259.
FrEGGs are a particular class of Evaporating Gaseous Globules (EGGs). Both frEGGs and EGGs are regions of gas that are sufficiently dense that they photoevaporate less easily than the less compact gas surrounding them. Photoevaporation occurs when gas is ionised and dispersed away by an intense source of radiation — typically young, hot stars releasing vast amounts of ultraviolet light. EGGs were only identified fairly recently, most notably at the tips of the Pillars of Creation, which were captured by Hubble in iconic images released in 1995. FrEGGs were classified even more recently, and are distinguished from EGGs by being detached and having a distinct ‘head-tail’ shape. FrEGGs and EGGs are of particular interest because their density makes it more difficult for intense UV radiation, found in regions rich in young stars, to penetrate them. Their relative opacity means that the gas within them is protected from ionisation and photoevaporation. This is thought to be important for the formation of protostars, and it is predicted that many FrEGGs and EGGs will play host to the birth of new stars.
The frEGG in this image is a dark spot in the sea of red light. The red colour is caused by a particular type of light emission known as H-alpha emission. This occurs when a very energetic electron within a hydrogen atom loses a set amount of its energy, causing the electron to become less energetic and this distinctive red light to be released.
[Image description: The background is filled with bright orange-red clouds of varying density. Towards the top-left several large, pale blue stars with prominent cross-shaped spikes are scattered. A small, tadpole-shaped dark patch floats near one of these stars. More of the same dark, dense gas fills the lower-right, resembling black smoke. A bright yellow star and a smaller blue star shine in front of this.]

La basílica de San Apolinar el Nuevo (en italiano: Basilica di Sant'Apollinare Nuovo) es un templo cristiano de la ciudad italiana de Rávena. Inicialmente, se consagró para el culto arriano, al ser construido por orden del rey ostrogodo Teodorico el Grande en 505; tras la conquista bizantina (540) fue habilitada para el culto católico (en la época no se había producido aún la separación de las iglesias oriental y occidental). Forma parte del conjunto monumental de ocho estructuras de Rávena inscritas en la lista del Patrimonio de la Humanidad en 1996.
Como todas las iglesias de Rávena segundo del periodo imperial (hasta 476), ostrogodo (hasta 540) y bizantino (después de esa fecha), también San Apolinar el Nuevo cuenta con unos singulares mosaicos. Sin embargo, no pertenecen a la misma época: los hay del periodo de Teodorico y otros pertenecientes a la reestructuración ordenada por el obispo Agnello, cuando se consagró el edificio al culto cristiano católico.
Las paredes de la nave central están divididas en tres zonas bien diferenciadas por su decoración. La parte más alta está decorada con una serie de recuadros alternados con el motivo alegórico de un pabellón con dos palomas. Los recuadros presentan escenas de la vida de Cristo con especial cuidado de los detalles, a pesar de que antiguamente estaban aún más elevados, por lo que su visión era bastante limitada. Algunas escenas evidencian la evolución en el arte del mosaico en la época de Teodorico.
La parte inferior, la de mayor tamaño, es también la más conocida. En los muros de la derecha (según se mira al altar), se representa el famoso Palacio de Teodorico, reconocible por la inscripción latina PALATIVM (Palacio) en la parte baja del tímpano. Los edificios interiores representados están mostrados en perspectiva resaltada. Eso significa que lo que se ve corresponde a tres lados del peristilo, dispuestos en un plano único. Entre las columnas hay telas blancas decoradas con oro, que cubren las sombras de antiguas figuras humanas que permanecieron después de que una parte del mosaico fuera condenada a ser destruida: por una especie de damnatio memoriae todas las figuras humanas (casi con toda seguridad el propio Teodorico y miembros de su corte) fueron eliminadas y aún se notan amplias partes de color ligeramente distinto (debidas a una restauración llevada a cabo en otro momento) y las evidentes marcas en las columnas blancas, en las que aparecen por diversos lugares marcas de manos.
Más allá del Palacio se descubren algunos edificios basilicales o de planta central cuya función es representar de modo sintético la ciudad de Rávena.
Las procesiones contrapuestas de los Santos Mártires y las Santas Vírgenes, también en la parte inferior, se realizaron durante el dominio bizantino (cuando Rávena era un Exarcado dependiente de Constantinopla) y evidencian algunos caracteres propios del arte del Imperio de Oriente como la repetición de los gestos, el preciosismo de la indumentaria, la falta de volumen (con el consiguiente aplanamiento o bidimensionalidad de las figuras) y también la absoluta frontalidad, la fijeza de las miradas, la práctica monocromía de los fondos dorados, el uso de elementos vegetales con fines ornamentales y de relleno, la falta de un plano de apoyo para las figuras que, por esa razón, aparecen como suspendidas y flotando en el mundo.

The Basilica of Sant'Apollinare Nuovo is a basilica church in Ravenna, Italy. It was erected by the Ostrogothic king Theodoric the Great as his palace chapel during the first quarter of the 6th century (as attested to in the Liber Pontificalis). This Arian church was originally dedicated in 504 AD to "Christ the Redeemer".
It was reconsecrated in 561 AD, under the rule of the Byzantine emperor Justinian I, under the new name "Sanctus Martinus in Coelo Aureo" ("Saint Martin in Golden Heaven"). Suppressing the Arian church, the church was dedicated to Saint Martin of Tours, a foe of Arianism. According to legend, Pope Gregory the Great ordered that the mosaics in the church be blackened, as their golden glory distracted worshipers from their prayers. The basilica was renamed again in 856 AD when relics of Saint Apollinaris were transferred from the Basilica of Sant'Apollinare in Classe because of the threat posed by frequent raids of pirates from the Adriatic Sea.
On the upper band of the left lateral wall are 13 small mosaics, depicting Jesus' miracles and parables; and on the right wall are 13 mosaics depicting the Passion and Resurrection. However, the flagellation and crucifixion are lacking. They describe the parts of the Bible that were read aloud in the church during Lent under the rule of Theodoric the Great. On the left, Jesus is always depicted as young, beardless man, dressed as a Roman Emperor. On the right, Jesus is depicted with a beard. For the Arians, this emphasized that Jesus grew older and became a "man of sorrows", as spoken of by the prophet Isaiah. These mosaics are separated by decorative mosaic panels depicting a shell-shaped niche with a tapestry, cross, and two doves. These mosaics were executed by at least two artists.

Macro 1X by focus stacking using the focus ring control
How do you can do it :
Ingredients:
-Nikon D600 + 105mm macro nikor 1X
-Helicon Remote control for automatic focus stack using the camera focus ring (using USB)
-Helicon Soft Focus Stacking (36 shots, Method B, R = 4, S = 2)
-Helicon: You can download a free trial for 1 month, or a license for a year for € 50, it controls almost many Nikon and Canon via USB. There are other suppliers of soft for stacking, p. ex. Zerene, ControlMyNikon or Canon, Combine Z, etc.
-optional: 3D (Up Plus 2) printer to manufacture light bulbs, brackets, desk, etc. You can use the friendly 123D Design (free soft) for pieces designing.
Recipe:
-Ilumination with 4 or 5 micro-LED bulbs. The lighters can be designed and printed using a 3D printer and then mount the LED´s (high brightness and 5300K), the power is 12VDC for groups of 3 or 4 LEDs. The advantage over use of flash, is that you can positioning the lights and lighting make up before shooting, in addition to the volume to be achieved by playing with these lighting.
-Shot photographs using, p. eg Helicon Remote. Helicon controls the approach to the movement of the focus ring before the photo shot, the whole process of taking pictures is automatic, you can watch videos on youtube
-For 1X do you needed 20-100 photos, depending on value of f, focal and deep of field needed, automatically calculated by the soft. Often used the sweet spot of the lens (usually in the vicinity of f5.6) to optimize results
-Now we stack of shots using Helicon Soft
-We can use Lightroom or the like to remove "halos" and "artifacts"
-Once you have practice, the whole process can take 15 min
-And sorry my English, please.

El Sol se pone, los ojos nos avisan de que quieren descansar...llevan todo el día mirando cada detalle que la vida nos regala. Sin embargo, mi Sol nunca se pone y mis ojos quieren seguir trabajando, y sé que hasta que no te encuentren no van a parar. Así paso noche tras noche, hasta que empiezo a ver que mi habitación se ilumina. Al ver la luz del Sol cada mañana, me doy cuenta de que la vida sigue adelante y que tengo que esforzarme por no perder el tren porque si lo pierdo no habrá una mínima oportunidad de encontrarte. Mi única opción es coger mi taza y rellenarla de esa sustancia que me mantiene despierta; esa sustancia que recorre mis venas cada mañana; esa sustancia, que como si de una droga se tratara, no puedo abandonar. A veces, me gustaría recorrer ese mundo que tengo tan abandonado, los sueños.

Ojalá hubiese grabao toas las fotos y tos los videos que habías enviado
Y esta noche mi mente te hubiese visitado
Ya que no te consigo por tenerme bloqueado
¿Dónde estarás que ya no respondes?
¿En qué cama nueva te escondes?
¿Y cómo se llama esa cabrona que ahora gritas su nombre?
Dime por qué no llamas,
Si yo sé que piensas en mi cuando estás con ella en la cama
Fumo pa no pensarte y me sale tu holograma
No olvido cómo mama y cómo te daba en toas las poses
El se hizo completo porque tenía el corazón roto
Borré los videos del carrete, pero en mi mente quedó tu foto
Solo dime dónde es que estás, que esto me está volviendo loca
Here we see JO204, a ‘jellyfish galaxy’ so named for the bright tendrils of gas that appear in this image to be drifting lazily below JO204’s bright central bulk. The galaxy lies almost 600 million light-years away in the constellation Sextans. This image was captured by the NASA/ESA Hubble Space Telescope, and it is the third of a series of Pictures of the Week featuring jellyfish galaxies. This series of images is possible thanks to a survey in which observations were made of six of these fascinating galaxies, including JO204. This survey was performed with the intention of better understanding star formation under extreme conditions.
Given the dreamy appearance of this image, it would be understandable to wonder why jellyfish galaxies should be such a crucible for star formation. The answer is that — as is often the case with astronomy — first appearances can be deceiving. Whilst the delicate ribbons of gas beneath JO204 may look like floating jellyfish tentacles, they are in fact the outcome of an intense astronomical process known as ram pressure stripping.
Ram pressure is a particular type of pressure exerted on a body when it moves relative to a fluid. An intuitive example is the sensation of pressure you experience when you are standing in an intense gust of wind — the wind is a moving fluid, and your body feels pressure from it. An extension of this analogy is that your body will remain whole and coherent, but the more loosely bound things — like your hair and your clothes — will flap in the wind. The same is true for jellyfish galaxies. They experience ram pressure because of their movement against the intergalactic medium that fills the spaces between galaxies in a galaxy cluster. The galaxies experience intense pressure from that movement, and as a result their more loosely bound gas is stripped away. This gas is mostly the colder and denser gas in the galaxy — gas which, when stirred and compressed by the ram pressure, collapses and forms new stars in the jellyfish’s beautiful tendrils.
[Image Description: A spiral galaxy in the centre is tilted almost edge-on. The bright core and spiral arms can just be seen from the top. A slight glow surrounds it. Below, strands made of bright blue patches trail down like tentacles. On the left it is just touched by a second, faint and dim galaxy. The background is very dark, with only a few other stars and tiny galaxies visible.]

Concordia research station in Antarctica is a place of extremes. In winter no sunlight is seen for four months and the typical crew of twelve live in complete isolation.
ESA sponsors a research medical doctor each year to study the effects of living in isolation. The extreme cold, isolation, sensory deprivation and remoteness make living in Concordia similar to living on another planet.

This extraordinary image from the NASA/ESA Hubble Space Telescope of the galaxy cluster Abell 2813 (also known as ACO 2813) has an almost delicate beauty, which also illustrates the remarkable physics at work within it. The image spectacularly demonstrates the concept of gravitational lensing.
Among the tiny dots, spirals, and ovals that are the galaxies belonging to the cluster, there are several distinct crescent shapes. These curved arcs of light aren’t curved galaxies. They are strong examples of a phenomenon known as gravitational lensing.
Gravitational lensing occurs when an object’s mass causes light to bend. The curved crescents and “S” shapes are light from galaxies that lie beyond Abell 2813. The galaxy cluster has so much mass that it acts as a gravitational lens, bending light from more distant galaxies around it. These distortions can appear as many different shapes, such as long lines or arcs.
This visual evidence, that mass causes light to bend, is famously used as proof of Einstein’s theory of general relativity.

Driving and walking rovers competed to survey a shadowy analogue of the south polar lunar surface for useable resources during the inaugural ESA-ESRIC Space Resources Challenge. Some 13 teams from across Europe and Canada took part in last month’s field test, with the winners due to be announced shortly.
The Space Resources Challenge – supported by ESA and the European Space Resources Innovation Centre (ESRIC) in Luxembourg – is asking European (and Canadian) researchers and institutions to develop and demonstrate a system of one or more vehicles capable of prospecting resources on the Moon in the near future.
Massimo Sabbatini, overseeing the contest for ESA, comments: “ESA is analysing the results of the first field test of the Challenge and the competition is fierce. There was a wide range of participants and technological solutions to the problem of prospecting: notably different locomotion techniques – legged, wheeled, tracked, and so on – and approaches, such as single versus multiple vehicles and aerial vehicles. The jury is out!”
The emphasis of the contest is on prospecting: pinpointing promising resources within a difficult lunar environment then characterising them in as much detail as possible, such as through visual inspection or spectral analysis.
The lunar poles are a focus of interest for future exploration. They do not experience the crippling temperature extremes of the Moon’s two-week days and nights, and frozen water and other deposits are believed to be buried within permanently shadowed polar craters.
The Space Resources Challenge teams gathered at Valkenberg in the Netherlands had to contend with challenging illumination conditions and potential loss of signal events to locate resources, including mapping a small impact crater in the vicinity of the rover’s lander – all within a two and a half hour time limit.
The five winners will be awarded €375 000 in ESA contracts, with a larger prize pool on offer after a follow-on field test hosted by ESRIC next year.

No creo que esas cosas puedan hacerte daño, pero si ves algo que no te guste limítate a mirar hacia otro lado, y cuando vuelvas a fijarte, la cosa habrá desaparecido.
... ví al cielo. Iba de prisa, como siempre, pero tuve la oportunidad de levantar la mirada y ver esto!
Me detuve... me tomé el tiempo para admirarlo. Lo fotografié. La gente me veía un poco raro... y la verdad es que no me importó! =)

Recuerdo que un amigo de Mérida me encontró una vez viendo al piso mientras caminaba por el centro de la ciudad. Me dijo:
- Los que miran al piso son unos perdedores, Tatiana!
Y yo le respondí:
- Si no miras al piso te puedes tropezar!
A veces pienso en lo que él me dijo esa tarde... y veo al cielo para sentirme un poco mejor.
Son reflexiones al final de un día lleno de cansancio, reuniones, carreras para llegar a tiempo... y fotografías.
