Measuring the Hubble constant, the rate at which the Universe is expanding, is an active area of research among astronomers around the world who analyze data from both ground- and space-based observatories. The NASA/ESA/CSA James Webb Space Telescope has already contributed to this ongoing discussion. Earlier this year, astronomers used Webb data containing Cepheid variables and Type Ia supernovae, reliable distance markers to measure the Universe’s expansion rate, to confirm the NASA/ESA Hubble Space Telescope’s previous measurements.
Now, researchers are using an independent method of measurement to further improve the precision of the Hubble constant — gravitationally lensed supernovae. Researchers from different institutions around the world are leading this effort after Webb’s discovery of three points of light in the direction of a distant and densely populated cluster of galaxies.
This is an image from Webb’s NIRCam (Near-Infrared Camera) of the galaxy cluster PLCK G165.7+67.0, also known as G165, on the left shows the magnifying effect a foreground cluster can have on the distant Universe beyond. The foreground cluster is 3.6 billion light-years away from Earth. The zoomed region on the right shows the supernova H0pe triply imaged (labeled with white dashed circles) due to gravitational lensing.
This field was selected for observation due to its high rate of star formation of more than 300 solar masses per year, an attribute that correlates with higher supernova rates. SN H0pe is one of the most distant Type Ia supernovae observed to date. The measured Hubble constant value matches other measurements in the local Universe, and is somewhat in tension with values obtained when the Universe was young. Future Webb observations in Cycle 3 will improve on the uncertainties.
In this image blue represents light at 0.9, 1.15, and 1.5 microns (F090W + F115W + F150W), green is 2.0 and 2.77 microns (F200W + F277W), and red is 3.56, 4.1, and 4.44 microns (F356W + F410M + F444W).
Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process.
[Image description: A two-panel image. In the left panel, dozens of small galaxies are scattered on the black background of space. Just to the left of the center, there is a long, red arc. At its left is a cluster of a few white galaxies that look like a glowing orb. To the right of the center, the red arc and glowing orb of galaxies at the left appear to be mirrored. The curved and distorted galaxy image on the right side is highlighted with a white box. Lines extend from the box’s corners to the right panel, which shows an enlarged view of the curved galaxy. Three faint points of light are circled.]

61-2667, the sole operational WC-135W Constant Phoenix is a "nuke sniffer," whose role is to sample and analyze the air for traces radioactive material. It will soon be replaced by a trio of new WC-135R aircraft, which are in the process of being converted from KC-135R tankers.
A historic harbor warehouse from 1923, once this was the largest storage and transfer shed in the world, designed by architect Cornelis van Goor and built by order of the Holland-America Line. The warehouse is then still called Shed San Francisco and is 360 meters long.
Rotterdam, the Netherlands.
In this city, the sun with rain is constantly changing, and the camera lens will often get some drops.
Whether it was the C&NW, DM&E, CP or RCP&E, this station sign at St. Onge has been through it all. The railroad may change, but some things don't.
On the top of XiaoYuShan (Little Fish Mountain), there is a pagoda... On the top of the pagoda, you can enjoy a beautiful 360° view of Qingdao, the old town with its red roofs, the modern city center on the other side, 180° of sea, beaches...
But I went there not for the panoramic view, but for the pagoda itself.
Stay tuned...

Commentary.
Oh, shadowy igneous, rocks.
Eroded remnants of a 60 million-year-old magma chamber
by glacier, constant freeze-thaw in cracks and dykes, gravity as boulders tumble, wind, rain and subsequent burns and rivers.
Foreground up to top left is the Black Cuillin, mostly Gabbro with some Basalt Dyke Intrusion.
Beyond these hills, towards top right, but before the sea channel is reached are the lighter-coloured Red Cuillin Hills, made of granitic intrusions.
Both sets of hills produced by massive eruptions
that may have emitted projectile rock and lava-flows to a volume of 15 cubic kilometres, equivalent to the Krakatoa blast.
Lava-flows travelled up to 41 km. to places like the Sgurr of Eigg where rapid cooling produced glassy igneous rocks like Pitchstone or Obsidian.
The Red Cuillins eroded much more evenly, hence their more even, rounded forms.
The Black Cuillin is a much more dramatic erosion
leaving a ten-mile serrated, knife-edge arête with frequent vertical clefts.
It is raw, bare, jagged and breath-taking.
Many climbers of the Himalayas, Alps, Dolomites, Andes and Rockies have loved this ridge as their training ground.
Few places in the world have 360° views of sea-channels, ocean, islands, mainland, bays, beaches headlands, peninsulas, valleys, forests and layered mountains into the distance.
The views are astounding and totally captivating, simply unforgettable.
No wonder that the Isle of Skye is often rated one of the single most amazing islands on Earth.
It undoubtedly is!

Another one dug up for future memory. As one of the most densely populated cities in the world, Hong Kong’s property cost has always been up there, in the stratosphere, actually. In fact, with the constant increase of tourists visiting, Hong Kong’s rent per square foot for commercial spaces in the last quarter of 2012 was world’s most expensive, topping that of New York City’s in the same period of time. That’s alright, it makes sense, lots of people, not enough land. That’s fine and dandy and it is just the way it works. What doesn’t make sense is the fact that some expects a fast food restaurant’s monthly rent to be in the millions. And when they can’t match the rent, they are forced to move away to lower tier areas. If one thinks that it is what it is, well, then that would mean that first tier property zones will be crammed with nothing but brand named jewelry stores, horology shops, and gold vendors. How can a neighborhood be all of those things only and not consist any places for humans to eat or shop for their everyday necessities. After all, even if we could all afford it, we can’t eat Vacheron Constantins for breakfast, lunch and dinner every day, and if you get major indigestion, good luck, cause there ain’t no doctor who can afford to be operating in the neighborhood. Basically, it is absurd the way the things are happening right now. As second and third tier zones become hot, their rents will also rise, then what?
Look at this view of TST’s branch of Tsui Wah restaurant’s neon sign now, as more than likely it will become memory only. Another similar eatery literally around the corner just closed not long ago, and they are having no success finding an ideal relocation.
Looking back on some images taken on a very cold winter day in January 2015, I chose one of the old, digitally-dusty frames to process as it had been neglected for far too long. In Port Dalhousie (technically, the Regional City of St Catharines, Ontario), the Welland Canal entrance from Lake Ontario offers protection to ships making the transit via a pair of piers that extend out into the lake some 1000 metres. On the East side of the East pier, a man-made spit has been made from materials dredged during both canal construction and the periodic maintenance operations. Toward the far extent of the spit, sumac has established itself, albeit in a somewhat stunted form due to the constant winds off Lake Ontario. In the winter, those same wind deposit fine mist from the lake on the sumac branches and occasional seals in snow from a recent snowfall, as seen here. I spent time time out here freezing various appendages as I crawled around with tripod and camera to capture the scene on this day. - JW

Mooie tentoonstelling in het Haags Gemeentemuseum.

In een van de ruimte is een houten trap gebouwd die je op eigen risico kunt betreden. Deze dame met bloemetjes jurk en een tasje van Tate had er plezier in.
The first time I shot CN's Scotford Alberta Industrial Job was in 2010. A the time the job used a trio of Canadian built GMD-1's and a Pointe St. Charles produced caboose to switch the industries on the spur near Fort Saskatchewan. Fast forward 8 years, and the GMD's and the caboose are gone, replaced by higher horsepower SD40's and a brakeman riding the last car. The industries and the job remain the same, and I wonder what will be used to switch the spur in another 8 years.
Rather than going with Dilution B or my standard Dilution H, I went a little dilute and took out Dilution F (1+79). Was it worth the long development time? You bet! These are fantastic results, though the one thing I'd probably do next is add a pale yellow filter. But you have low-to-mid contrast, good sharpness, and a good grain structure.
The full review drops in January 2026!

One has to move fast when shooting sunsets as the light changes so quickly. When combining rapidly changing light and long exposure photography you need to be on your game - a mistake in overall timings can set you back and having to start again may mean the beautiful light you started with, has gone. This is a 5 minute exposure on the south-eastern side of Derwent Water in the Lake District in England. The combination of long exposure and a very lazy wind that evening worked well - the clouds in the sky are moving creting an effect like a paintbrush but I like how the detail in the pink clouds can still be seen.

Built May 1879 at Cardiff TVR West Yard Works
Withdrawn by GWR as loco 450 in Oct 1926
Sold to Longmoor Military Railway and named "Gordon" number WD285.
Sold in 1947 to National Coal Board South Hetton County Durham
Presented in 1962 to British Railways (Western) and sent to Caerphilly works (see photo).
Last loco to be overhauled at Caerphilly before closure in 1963 back to TVR Black livery as no.28.
Stored at Swindon and Stratford.
Custody given to the National Museum of Wales on behalf of the National Rail Museum
Returned to Caerphilly in July 1967 and ran on the short Caerphilly Rail Soc site.
May 1983 saw Taff Vale engine number 28 returned to steam at Caerphilly. In 1991 it was taken to Cathays Depot, Cardiff for display during the Taff Vale 150 celebrations there. Unfortunately, after this event, lack of funds prevented the Society returning this magnificent loco back to steam and it was placed in store at Caerphilly.
After the demise of the Caerphilly venture in 1996 due to constant vandalism No 28 was moved in May 1996 and dismanted on the Dean Forest Railway apparently for assessment and restoration for a return to steam by 2000. However the necessary repairs were going to be expensive.
Now its still dismanted 13 years on with some parts at Llangollen scattered in bushes.
National Welsh heritage scandal, come on National Museum of Wales / NRM at least put it back together on display.
2014 all the bits finally put back together and put on display as a non steamer at the Gwilli Railway in West Wales.

Groundbreaking for Miami-Dade College's Wolfson Building 1 occurred in 1971, and the building was completed in 1973. The campus itself first opened in 1970, with classes initially held in downtown storefronts while its permanent facility was being constructed.
Hilario Candela was the architect of Miami-Dade College's Wolfson Building 1. As a Cuban-born American architect, he designed key Brutalist-style buildings for several of the college's campuses, including Wolfson.
Candela was a key member of the architectural firm Pancoast, Ferendino, Grafton & Skeels, which designed the initial buildings for the North and Kendall campuses in the 1960s.
His signature "tropical Brutalist" style, with its use of raw concrete, is a defining feature of the Wolfson Campus architecture.
In addition to his work for Miami-Dade College, Candela is also known for designing the iconic Miami Marine Stadium.
Miami-Dade College's Wolfson Building 1 was designed in the Brutalist style, specifically a regional variant referred to as "tropical Brutalism".
Elements of this architectural style as seen in the Wolfson Campus include:
Raw concrete: The buildings prominently feature exposed concrete, emphasizing the material's raw, unadorned nature.
Massive, geometric forms: Brutalist buildings are known for their blocky and monolithic appearance. Architect Hilario Candela, who designed the Wolfson Campus, referred to his vision as "a small city of interconnected geometric masses".
Function over form: In keeping with Brutalist ethos, the building's design emphasizes its function as a modern educational institution.
Adaptation to the Miami climate: In this "tropical Brutalist" interpretation, the buildings use covered walkways and strategically placed open spaces to provide constant shade and cover from the rain.

Constant parade of gigantic mine dump trucks hauling overburden and copper ore out of the mine at the RioTinto/Kennecott Bingham Canyon open pit copper mine in Salt Lake County, Utah.
• The trucks that haul the ore are larger than many houses and weigh more than a jumbo jet. They stand over 23 feet tall and can carry from 255 to 360 tons of rock.
• The truck driver rides about 18 feet above the ground -- nearly two stories high.
• Each tire on these big trucks costs from $18,000 to $26,000 and lasts just 9 months.
