NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago.
In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter. But how? This was puzzling.
To answer this question, researchers used Webb to study stars in a nearby galaxy that, much like the early universe, lacks large amounts of heavy elements. They found that not only do some stars there have planet-forming disks, but that those disks are longer-lived than those seen around young stars in our Milky Way galaxy.
This is a James Webb Space Telescope image of NGC 346, a massive star cluster in the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way's nearest neighbors. With its relative lack of elements heavier than hydrogen and helium, the NGC 346 cluster serves as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe. Ten, small, yellow circles overlaid on the image indicate the positions of the ten stars surveyed in this study.

On our planet, water is life. But how did it get here? Are there similar environments around other stars?
Webb has us one step closer to the answers. In a still-developing “solar system,” Webb detected water in the zone where rocky planets like Earth may form.
PDS 70 is a K-type star cooler than our Sun. Around it is a huge disk made up of planet-forming materials, including 2 known gas giant planets in the making. Webb found water vapor in the inner disk of PDS 70, within 100 million miles of the star.
Though we’ve seen water in similar disks, Webb’s discovery is the first detection of water in the “rocky planet zone” of a system known to have 2 or more developing planets. That means if rocky planets someday form around PDS 70, they’ll have water ready and waiting.
Follow-up observations will dive deeper into new mysteries, such as the origins of the water around PDS 70. In turn, studying other worlds will help us gain insight into our own. More: go.nasa.gov/3O8NL2j
This image: ARTIST ILLUSTRATION
This artist concept portrays the star PDS 70 and its inner protoplanetary disk. New measurements by NASA’s James Webb Space Telescope have detected water vapor at distances of less than 100 million miles from the star – the region where rocky, terrestrial planets may be forming. This is the first detection of water in the terrestrial region of a disk already known to host two or more protoplanets, one of which is shown at upper right.

Image description: Left of center, a bright light source illuminates a surrounding disk colored dusky red. The disk has spiral features and a scattering of small, rocky objects. At upper right, there is a gap through which background stars can be seen. At the outer edge of the gap is a dusky globe representing a gas giant planet. Beyond it is additional disk material, some of which is falling onto the planet.

This Mountain Hare is resting in its form on a heather covered hillside at Glenshee in the Scottish Highlands.
In the UK, Mountain Hares live in the Scottish Highlands and England's Peak District, grazing on vegetation and nibbling bark from young trees and bushes. They shelter in a ‘form’, which is simply a shallow depression in the ground or heather.
They are at their most visible in spring, when the snow has melted but the hares are still white, like this one.
Mountain Hares can reach 65cm in length and can weigh up to 5.3kg.

C'est lors d'une balade en bus dans la ville de Abu Dhabi que nous avons visité le Mall de la Marina présentant un plafond original faisant apparaître une gaufre croustillante en forme de croissant.
I recently acquired a +3 magnifying filter that threads onto my Nikkor 18-200mm lens and allows me to truly "fill the frame" when I use both of these tools together.
It is a bit tricky to work with since the combo produces a very shallow depth of field, but I'm pleased that a $25.00 filter can be so helpful for those of us who enjoy seeing the nature world up close......
One in a series of images titled 'Form minus Function'.
It's fair to say that type and ink only ever meet on a printed page. In this series of images, the two elements are presented to us in a way that is a little more unusual. Images of black and white ink in water are accompanied by small typographical letters to generate strange yet captivating forms that appear to float effortlessly in the air.
A contemporary tribute to traditional methods of print.
Best viewed large!

En el recinto del Castillo, con forma de polígono irregular, se distinguen dos partes diferenciadas: la parte norte, del siglo XII, y el resto, construido a lo largo del siglo XV, con algunas obras realizadas en los siglos XIX y XX. En tiempos pretéritos el castillo estuvo rodeado por un foso, excepto en el lienzo noroccidental, donde el río cumplía esa misma función.
En el interior existe un grupo de fortificaciones del siglo XII de origen templario: los restos de una barbacana en el acceso a un patio, al que abren la torre elíptica, parte del paseo de ronda, una torre que tuvo tres pisos, la torre del Malvecino y otra torre en la que destaca una puerta de arco apuntado, de gran valor artístico.
La fachada noroeste constituye un parapeto corrido que termina en la torre del Moclín, de planta hexagonal irregular. Bajo él se abría una nueva ronda que defendía el subterráneo que unía el castillo con un aljibe, situado en una torre albarrana.
La portada principal, de mampostería, está compuesta por dos torreones que flanquean un amplio arco de medio punto. Tras este arco se alzaban las puertas de acceso al patio en el que, a la izquierda, se sitúa la torre del homenaje, desde la que se accede a la patio de armas, hoy cubierto de escombros.
Antes de entrar en el patio hay un recinto defensivo que conduce a la torre Cabrera, situada al sur y comunicada con la primera línea defensiva del lado este, en cuyo punto medio se alza una torre semicircular, destinada a calabozos y a la comunicación con la segunda línea de defensa. El paramento continúa hacia el norte, encontrándose otra torre cuadrada, antes de acceder a la torre de Malvecino, del siglo XV.
En el patio de armas, adosadas a otra línea defensiva, se encuentran varias dependencias, como la Galería de los Azulejos, derruidas y cubiertas de escombros debido a que 1811 una orden de la Regencia del Reino manda que vuelen las dependencias interiores (el daño no debió ser muy grande porque en 1815 se ofreció en sus salones un baile de sociedad) y a que desde que en 1848 el Ayuntamiento de Ponferrada, con la oposición frontal de la Comisión de Monumentos de Ponferrada, la empezase a utilizar como cantera local y mil otras felonías que culminaron en 1923 cuando se volaron sus muros para la construcción de un campo deportivo.
Venice (English /ˈvɛnɪs/; Italian: Venezia [veˈnɛttsia] ( listen)[1] alternative obsolete form: Vinegia; Venetian: Venexia [veˈnɛsja]; Latin: Venetiae; Slovene: Benetke) is a city in northeastern Italy sited on a group of 117 small islands separated by canals and linked by bridges.[2] It is located in the marshy Venetian Lagoon which stretches along the shoreline, between the mouths of the Po and the Piave Rivers. Venice is renowned for the beauty of its setting, its architecture, and its artworks.[2] The city in its entirety is listed as a World Heritage Site, along with its lagoon.[2]
Venice is the capital of the Veneto region. In 2009, there were 270,098 people residing in Venice's comune (the population estimate of 272,000 inhabitants includes the population of the whole Comune of Venezia; around 60,000[3] in the historic city of Venice (Centro storico); 176,000 in Terraferma (the Mainland), mostly in the large frazioni (roughly equivalent to "parishes" or "wards" in other countries) of Mestre and Marghera; 31,000 live on other islands in the lagoon). Together with Padua and Treviso, the city is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), with a total population of 1,600,000. PATREVE is only a statistical metropolitan area without any degree of autonomy.
The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC.[4][5] The city historically was the capital of the Republic of Venice. Venice has been known as the "La Dominante", "Serenissima", "Queen of the Adriatic", "City of Water", "City of Masks", "City of Bridges", "The Floating City", and "City of Canals". Luigi Barzini described it in The New York Times as "undoubtedly the most beautiful city built by man".[6] Venice has also been described by the Times Online as being one of Europe's most romantic cities.[7]
The Republic of Venice was a major maritime power during the Middle Ages and Renaissance, and a staging area for the Crusades and the Battle of Lepanto, as well as a very important center of commerce (especially silk, grain, and spice) and art in the 13th century up to the end of the 17th century. This made Venice a wealthy city throughout most of its history.[8] It is also known for its several important artistic movements, especially the Renaissance period. Venice has played an important role in the history of symphonic and operatic music, and it is the birthplace of Antonio Vivaldi.

Similar in scale and form to the example on the Causse de Lunas (see below), a warm water form in a monolithic block that is tilting and slipping down a gully. Although not obvious, the monolith is tilting at around 45 degrees and needs to be boxed in timber before being dragged on rails to a new resting place tens of meters to the north. An important project for the territorial army and their engineer brigade, with coordination from local heavy equipment as the rock is in the multiple hundreds of tonnes and if it slides further would present far greater problems. I have yet to feature this example in my album on the subject, and it is to be found up valley from Ayguebonne, hidden in a scribble of scrub and land slip.
See how the top 'pool' seems flatly functional and the near pool seems to suggest representation more than function, with its undulated token surface. The explanation I offer for this seeming anomaly is in the text associated with my pottery model linked below.
The stitch for this image was rushed and I hope one day to have the time to reupload a cleaner version.
