A veces no ves esa luz...
A veces la buscas...
Con o sin éxito...
Cuando la encuentras, la pierdes´otra vez...
Y cuando de repente un día te tropiezas con ella te come la nostalgia.
No se que es, pero me gusta
:)

Rosetta is an impressive European spacecraft on its way to the unlikely-named comet 67 P/Churyumov-Gerasimenko. Once it arrives in 2014 it will extensively map the comet’s solid nucleus and, incredibly, even deploy a lander which will take close-up pictures and sample the comet’s material.
Comets are on orbits that can make them difficult to reach, so the gravity of planets must be "borrowed" to get the probe to its destination. In November 2009, Rosetta swung by the Earth for its third and final assist. While it was still over 600,000 km (360,000 miles) away, it took this remarkable image of our home.
It’s easy to forget how special our world is. Pictures like this remind us how stunning and beautiful it is, a planet both mundane and special, ordinary and unique.
To the human eye, Mercury may resemble a dull, grey orb but this enhanced-colour image from NASA’s Messenger probe, tells a completely different story. Swathes of iridescent blue, sandy-coloured plains and delicate strands of greyish white, create an ethereal and colourful view of our Solar System’s innermost planet.

no es cualquier ventana. No. Es una de las ventanas de la casa del campo de mis padres y que antes fue de mi abuelo. Lugar en el que jugué y de la que tengo lindos recuerdos. Casa que ya no me resultaba tan querida y entrañable en mi adolescencia cuando pasarme un finde en el campo no era el mejor programa, aunque a veces si me llevaba amigas con quienes compartir podia ser el mejor plan. Luego, ya con hijos el campo volvió a ser el mejor lugar en el que compartimos infinidad de aventuras. Y ahora con hijos adolescentes tengo la suerte de que como vamos poco y siempre invitan amigos para ellos es un buen programa.

Los caminos se bifurcan, cada uno toma una dirección pensando que al final
los caminos se volverán a unir… pero no es así.
Desde tú camino ves a la otra persona cada vez más pequeña.
No pasa nada, estamos hechos el uno para el otro, ahí está ella, al final solo ocu-
rre una cosa, llega el invierno no hay vuelta atrás, lo sientes, y justo entonces
intentas recordar en que momento comenzó todo y descubres que todo empezó
antes de lo que pensabas…
Mucho antes…y es ahí justo en ese momento cuando te das cuenta de que las
cosas solo ocurren una vez, y que por mucho que te esfuerces, ya nunca volverás
a sentir lo mismo, ya nunca tendrás la sensación de estar a tres metros sobre el
cielo.
-----------------------------------------------------------------------------------------------------------------------------
The ways bifurcate, each one takes a direction thinking that ultimately the ways
will return to join … but it is not like that.
From you way you see another person increasingly small.
Nothing happens, we are done one for other one, there she is, ultimately only
a thing happens, comes the winter has not gone back, you feel it, and I joust at
the time you try to remember in that moment began everything and discover
that everything began before what you were thinking … Very much before … and
it is there just in this moment when you realize that the things only happen once,
and that for much that you strain, already you will never return to feel the same
thing, already you will never have the sensation of being to three meters on the
sky.

La vieja casa en silencio
y ninguno se lo explica,
cómo pasan esa cosas
tan feliz que parecía.
Mi madre llora en el patio,
Pedro duerme en la cocina,
y ninguno se ha acordado
de que coman las gallinas.
María llega de lejos
ella que nunca venía,
y el tío Luis a mi hermano
le dice un par de mentiras.
El crucifijo de plata
se lo lleva Catalina,
la mecedora Francisco
y la mantilla Corina.
El perro no entiende nada,
el gato ya lo sabía,
él fue después del abuelo
el que más la conocía.
La vieja casa en silencio
y ninguno se lo explica,
cómo pasan esas cosas
tan feliz que parecía.
Cómo pasan esas cosas...
tan feliz que parecía!

ESA astronaut Samantha Cristoforetti, arriving in Cologne, Germany on 15 October 2022.
Samantha’s Minerva mission began on 27 April 2022, when she was launched from Florida’s Kennedy Space Centre, USA, as part of Crew-4. While this mission was not her first to the International Space Station, it was packed full of groundbreaking moments.
On 21 July, Samantha completed her first spacewalk, outfitting the European Robotic Arm alongside Oleg Artemyev. This European project is capable of ‘walking’ between locations on the Station, offering grappling, transport, and installation assistance for payloads. Beyond this activity being a personal milestone, this extravehicular activity also made her the first European woman to spacewalk.
Samantha assumed the role of commander on 28 September, making her the fifth European, and first European woman, to hold the leadership position of the International Space Station. As commander, Samantha was responsible for the performance and well-being of her colleagues in space, maintaining effective communication with the teams on Earth, and coordinating crew response in case of emergencies. At the end of her mission, she assured a smooth transition between Expedition 67 and Expedition 68.
SpaceX’s Crew Dragon Freedom transporting Crew-4 autonomously undocked from the International Space Station and after a series of burns, entered Earth’s atmosphere and deployed parachutes for a soft water-landing. Samantha and Crew-4 splashed down on 14 October 2022 at 21:55 BST (22:55 CEST).

Esa-Pekka Salonen: conductor and composer of the "Sinfonia concertante for organ and orchestra".
Olivier Latry: organist.
Gothenburg Symphony Orchestra.
The organ is called "the queen of instruments" and for a good reason: no other acoustic instrument is so varied in sound and dynamics, from the weakest, solitary tone to massive chords that make it vibrate in floors and walls. It will for sure do so in the Great Hall in Gothenburg Concert Hall when the sound from the over 9000 organ pipes fills the room.
The world-class concert hall organ was built by Rieger Orgelbau in Austria and installed between 2019 and 2021. The instrument is so big that some of the organ pipes have been built in under the audience in the salon – when you sit on the parquet you feel the vibrations from the bass pipes!

A delicate tracery of dust and bright star clusters threads across this image from the NASA/ESA/CSA James Webb Space Telescope. In this image, from Webb’s MIRI instrument, the dusty structure of the spiral galaxy and glowing bubbles of gas containing newly-formed star clusters are particularly prominent. These bright tendrils of gas belong to the barred spiral galaxy NGC 5068, located around 17 million light-years from Earth in the constellation Virgo.
This portrait of NGC 5068 is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. Previous gems from this collection can be seen here and here. These observations are particularly valuable to astronomers for two reasons. The first is because star formation underpins so many fields in astronomy, from the physics of the tenuous plasma that lies between stars to the evolution of entire galaxies. By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb.
The second reason is that Webb’s observations build on other studies using telescopes including the NASA/ESA Hubble Space Telescope and some of the world’s most capable ground-based observatories. Webb collected images of 19 nearby star-forming galaxies which astronomers could then combine with catalogues from Hubble of 10 000 star clusters, spectroscopic mapping of 20 000 star-forming emission nebulae from the Very Large Telescope (VLT), and observations of 12 000 dark, dense molecular clouds identified by the Atacama Large Millimeter/submillimeter Array (ALMA). These observations span the electromagnetic spectrum and give astronomers an unprecedented opportunity to piece together the minutiae of star formation.
Three asteroid trails intrude into this image, visible as tiny blue-green-red dots. Asteroids appear in astronomical images such as these because they are much closer to the telescope than the distant target. As Webb captures several images of the astronomical object, the asteroid moves, so it shows up in a slightly different place in each frame. They are a little more noticeable in images such as this one from MIRI, because many stars are not as bright in mid-infrared wavelengths as they are in near-infrared or visible light, so asteroids are easier to see next to the stars. One trail lies just below the galaxy’s bar, and two more in the bottom-left corner - can you spot them?

Image description: Webb’s mid-infrared image of barred spiral galaxy NGC 5068. The galaxy’s core and part of a spiral arm can be seen on a dark background. Web-like clumps and filaments of dust thread through it, represented by the color gray. They form an almost skeletal structure that follows the twist of the galaxy and its spiral arm. Large, glowing bubbles of gas, represented in red, are hidden in the dust. Relatively few bright stars are visible throughout. They are most concentrated in the galactic core, seen as a clump of blue points in the top left quadrant.
Early on 8 April 2024, a citizen scientist found a comet in images from the ESA/NASA Solar and Heliospheric Observatory (SOHO). It follows the recent discovery of SOHO’s 5000th comet. But this one – named Comet SOHO-5008 – was special for a different reason.
Karl Battams (US Naval Research Lab), manager of the SOHO Sungrazer Project, predicted that comet SOHO-5008 would be visible during the total solar eclipse, which was due to plunge parts of the United States and Mexico into darkness later that very same day.
Petr Horálek, from the Institute of Physics in Opava (Czechia), was in Mexico for the eclipse. The clouds cleared and Petr could take this beautiful shot of the Sun’s awe-inspiring corona. To the lower left of the Sun, Comet SOHO-5008 is revealed.
Soon after Petr captured the comet on camera, it met its demise, coming so close to the Sun that it disintegrated.
Observations of these ‘sungrazing’ comets from the ground are extremely rare, and this sighting was only possible thanks to the total solar eclipse.
The image is a composite of 100 frames, with the wide corona imaged at a focal length of 200 mm (exposure time from 1/4000 to 2 seconds) and the inner corona imaged at a focal length of 1100 mm (exposure time from 1/500 to 4 seconds).
SOHO’s prowess as a comet-hunter was unplanned, but turned out to be an unexpected success. With its clear view of the Sun’s surroundings, SOHO can easily spot sungrazing comets. This has made it the most prolific discoverer of comets in astronomical history.

SOHO is a cooperative effort between ESA and NASA. Mission control is based at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. SOHO’s Large Angle and Spectrometric Coronagraph Experiment (LASCO), the instrument that provides most of the comet imagery, was built by an international consortium, led by the US Naval Research Lab.

In anticipation of the upcoming 35th anniversary of the NASA/ESA Hubble Space Telescope, ESA/Hubble is continuing the celebrations with a new image of the Sombrero Galaxy, also known as Messier 104. An eye-catching target for Hubble and a favourite of amateur astronomers, the enigmatic Sombrero Galaxy has features of both spiral and elliptical galaxies. This image incorporates new processing techniques that highlight the unique structure of this galaxy.
As part of ESA/Hubble’s 35th anniversary celebrations, a new image series is being shared to revisit stunning Hubble targets that were previously released. First, a new image of NGC 346 was published. Now, ESA/Hubble is revisiting a fan-favourite galaxy with new image processing techniques. The new image reveals finer detail in the galaxy’s disc, as well as more background stars and galaxies.
Several Hubble images of the Sombrero Galaxy have been released over the past two decades, including this well-known Hubble image from October 2003. In November 2024, the NASA/ESA/CSA James Webb Space Telescope also gave an entirely new perspective on this striking galaxy.
Located around 30 million light-years away in the constellation Virgo, the Sombrero Galaxy is instantly recognisable. Viewed nearly edge on, the galaxy’s softly luminous bulge and sharply outlined disc resemble the rounded crown and broad brim of the Mexican hat from which the galaxy gets its name.
Though the Sombrero Galaxy is packed with stars, it’s surprisingly not a hotbed of star formation. Less than one solar mass of gas is converted into stars within the knotted, dusty disc of the galaxy each year. Even the galaxy’s central supermassive black hole, which at 9 billion solar masses is more than 2000 times more massive than the Milky Way’s central black hole, is fairly calm.
The galaxy is too faint to be spotted with unaided vision, but it is readily viewable with a modest amateur telescope. Seen from Earth, the galaxy spans a distance equivalent to roughly one third of the diameter of the full Moon. The galaxy’s size on the sky is too large to fit within Hubble’s narrow field of view, so this image is actually a mosaic of several images stitched together.
One of the things that makes this galaxy especially notable is its viewing angle, which is inclined just six degrees off of the galaxy’s equator. From this vantage point, intricate clumps and strands of dust stand out against the brilliant white galactic nucleus and bulge, creating an effect not unlike Saturn and its rings – but on an epic galactic scale.
[Image description: The Sombrero Galaxy is an oblong, pale white disc with a glowing core. It appears nearly edge-on but is slanted slightly in the front, presenting a slightly top-down view of the inner region of the galaxy and its bright core. The outer disc is darker with shades of brown and black. Different coloured distant galaxies and various stars are speckled among the black background of space surrounding the galaxy.]

A transmission spectrum made from a single observation using Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b.
A transmission spectrum is made by comparing starlight filtered through a planet’s atmosphere as it moves across the star, to the unfiltered starlight detected when the planet is beside the star. Each of the 141 data points (white circles) on this graph represents the amount of a specific wavelength of light that is blocked by the planet and absorbed by its atmosphere.
In this observation, the wavelengths detected by NIRISS range from 0.6 microns (red) to 2.8 microns (in the near-infrared). The amount of starlight blocked ranges from about 13,600 parts per million (1.36 percent) to 14,700 parts per million (1.47 percent).
Researchers are able to detect and measure the abundances of key gases in a planet’s atmosphere based on the absorption pattern—the locations and heights of peaks on the graph: each gas has a characteristic set of wavelengths that it absorbs. The temperature of the atmosphere can be calculated based in part on the height of the peaks: a hotter planet has taller peaks. Other characteristics, like the presence of haze and clouds, can be inferred based on the overall shape of different portions of the spectrum.
The gray lines extending above and below each data point are error bars that show the uncertainty of each measurement, or the reasonable range of actual possible values. For a single observation, the error on these measurements is remarkably small.
The blue line is a best-fit model that takes into account the data, the known properties of WASP-96 b and its star (e.g., size, mass, temperature), and assumed characteristics of the atmosphere. Researchers can vary the parameters in the model – changing unknown characteristics like cloud height in the atmosphere and abundances of various gases – to get a better fit and further understand what the atmosphere is really like. The difference between the best-fit model shown here and the data simply reflects the additional work to be done in analysing and interpreting the data and the planet.
Although full analysis of the spectrum will take additional time, it is possible to draw a number of preliminary conclusions. The labelled peaks in the spectrum indicate the presence of water vapour. The height of the water peaks, which is less than expected based on previous observations, is evidence for the presence of clouds that suppress the water vapor features. The gradual downward slope of the left side of the spectrum (shorter wavelengths) is indicative of possible haze. The height of the peaks along with other characteristics of the spectrum is used to calculate an atmospheric temperature of about 1350°F (725°C).
This is the most detailed infrared exoplanet transmission spectrum ever collected, the first transmission spectrum that includes wavelengths longer than 1.6 microns at such high resolution and accuracy, and the first to cover the entire wavelength range from 0.6 microns (visible red light) to 2.8 microns (near-infrared) in a single shot. The speed with which researchers have been able to make confident interpretations of the spectrum is further testament to the quality of the data.
The observation was made using NIRISS’s Single-Object Slitless Spectroscopy (SOSS) mode, which involves capturing the spectrum of a single bright object, like the star WASP-96, in a field of view.
WASP-96 b is a hot gas giant exoplanet that orbits a Sun-like star roughly 1,150 light years away, in the constellation Phoenix. The planet orbits extremely close to its star (less than 1/20th the distance between Earth and the Sun) and completes one orbit in less than 3½ Earth-days. The planet’s discovery, based on ground-based observations, was announced in 2014. The star, WASP-96, is somewhat older than the Sun, but is about the same size, mass, temperature, and colour.
The background illustration of WASP-96 b and its star is based on current understanding of the planet from both NIRISS spectroscopy and previous ground- and space-based observations. Webb has not captured a direct image of the planet or its atmosphere.
NIRISS was contributed by the Canadian Space Agency. The instrument was designed and built by Honeywell in collaboration with the Université de Montréal and the National Research Council Canada.
