The combined observations from multiple telescopes of Henize 2-10, a dwarf starburst galaxy located about 30 million light years from Earth, has provided astronomers with a detailed new look at how galaxy and black hole formation may have occured in the early Universe. This image shows optical data from the Hubble Space Telescope in red, green and blue, X-ray data from NASA's Chandra X-ray Observatory in purple, and radio data from the National Radio Astronomy Observatory's Very Large Array in yellow. A compact X-ray source at the center of the galaxy coincides with a radio source, giving evidence for an actively growing supermassive black hole with a mass of about one million times that of the sun.
Stars are forming in Henize 2-10 at a prodigious rate, giving the star clusters in this galaxy their blue appearance. This combination of a burst of star formation and a massive black hole is analogous to conditions in the early Universe. Since Henize 2-10 does not contain a significant bulge of stars in its center, these results show that supermassive black hole growth may precede the growth of bulges in galaxies. This differs from the relatively nearby Universe where the growth of galaxy bulges and supermassive black holes appears to occur in parallel.

The cognoscenti will recognise these lines as those of a Batch II Type 22 frigate of the Royal Navy.
This is HMS Boxer, F92, and the image was taken by a member of the Fleet Photographic Unit, Portsmouth, at sea in the English Channel in May 1986. The Royal Navy holds the copyright for this image, which I acquired whilst serving aboard her. The Batch IIs were stretched versions of the Batch I Type 22s, Boxer being the first of six built.
A major improvement from the originals was the addition of a new Computer Assisted Command System (CACS-1), replacing the CAAIS fitted to the Batch Is.This could track up to 500 targets, including those detected by the ship's passive towed array and ESM.
However, the most significant change in these anti-submarine frigates was a much more sophisticated electronic warfare system, particularly the Classic Outboard system for the intercept of Soviet tactical naval communications. These very sophisticated and specialised versions of the Type 22 were apparently specifically approved by Prime Minister James Callaghan. The larger hull also improved sea keeping. However, the batch apparently never achieved the anticipated quietness for fully-effective use of their towed arrays, reportedly due to a failure to isolate the diesel generators from the hull.
Post-Cold War, their specialised nature, large crew size and operating costs meant the Royal Navy could not afford to keep them running. And there was very little interest from anywhere else. In 1999, Boxer was decommissioned. She was used as a target in 2004.

Very Large Array (VLA) near Socorro, New Mexico. Visit during a storm created some interesting photographs.
One of the best features of my iPhone is the ability to do decent pano shots so very easily.
These tulips just begged for a wider shot of the flowerbed to show off the varieties of colors all complimenting each other so very well.
These are photos taken on my trip to Europe and the UK with a girl friend in October to November 2012. My camera I had then wasn't good with low light so some of these shots are not great but I have put them as my memories of the trip.
Day in Oxford on a cold October day in 2012. We stayed here two nights.
Christ Church Cathedral.
The cathedral was originally the church of St Frideswide's Priory. The site was historically presumed to be the location of the nunnery founded by St Frideswide, the patron saint of Oxford, and the shrine now in the Latin Chapel, originally containing relics translated at the rebuilding in 1180, was the focus of pilgrimage from at least the 12th until the early 16th century.
In 1522, the priory was surrendered to Thomas Cardinal Wolsey, who had selected it as the site for his proposed college. However, in 1529 the foundation was taken over by Henry VIII. Work stopped, but in June 1532 the college was refounded by the King. In 1546, Henry VIII transferred to it the recently created See of Oxford from Osney. The cathedral has the name of Ecclesia Christi Cathedralis Oxoniensis, given to it by Henry VIII's foundation charter.
There has been a choir at the cathedral since 1526, when John Taverner was the organist and also master of the choristers. The statutes of Wolsey's original college, initially called “Cardinal College”, mentioned 16 choristers and 30 singing priests.
Christ Church Cathedral is one of the smallest cathedrals in the Church of England.
The nave, choir, main tower and transepts are late Norman. There are architectural features ranging from Norman to the Perpendicular style and a large rose window of the ten-part (i.e. botanical) type.

Oxford, a city in central southern England, revolves around its prestigious university, established in the 12th century. The architecture of its 38 colleges in the city’s medieval center led poet Matthew Arnold to nickname it the 'City of Dreaming Spires'. University College and Magdalen College are off the High Street, which runs from Carfax Tower (with city views) to the Botanic Garden on the River Cherwell.
We drove to New Mexico for the annual opening of the Trinity Site, but the VLA totally stole the show.
Inside the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida, technicians monitor the progress as a crane is used to lift and stack the third set of two International Space Station Roll Out Solar Arrays (iROSA) onto a platform on March 23, 2023. They are being prepared for delivery to the space station aboard SpaceXâs Dragon cargo carrier on the companyâs 28th commercial resupply services (CRS-28) mission to the space station. iROSA is a new type of solar panel that rolls open in space and is more compact than current rigid panel designs.

Detroit Edison 203 is draped in colorful Christmas lights once again on a foggy Christmas Eve. 203 was built by Baldwin in 1923, first working at Detroit Edison's Delray plant. It was transferred to Conners Creek and then finally Marysville in 1949. It shuffled coal cars around the Mighty Marysville until 1958 when it was donated to the city's park. Since then its mysteriously lost its headlight and numberplate on the smokebox, but nonetheless its kept up appearances with a repaint back in 2017. The Boy Scouts of America sponsor the locomotive's festive decor each year as it sits amongst the park's colorful array of lights.
The Qutb complex (Hindi: कुत्ब , Urdu: قطب), also spelled Qutab (Hindi: क़ुतब, Urdu: قطب) or Qutub (Hindi: क़ुतुब, Urdu: قطب), is an array of monuments and buildings at Mehrauli in Delhi, India.
Above the foundations of Lal Kot, the “first city of Delhi” founded in the eleventh century by the Tomar Rajputs, stand the first monuments of Muslim India, known as the Qutb Minar Complex. One of Delhi’s most famous landmarks, the fluted red-sandstone tower of the Qutb Minar tapers upwards from the ruins, covered with intricate carvings and deeply inscribed verses from the Koran, to a height of just over 72m. In times past it was considered one of the “Wonders of the East”, second only to the Taj Mahal; but historian John Keay was perhaps more representative of the modern eye when he claimed that the tower had “an unfortunate hint of the factory chimney and the brick kiln; a wisp of white smoke trailing from its summit would not seem out of place”.
Work on the Qutb Minar started in 1202; it was Qutb-ud-Din Aibak’s victory tower, celebrating the advent of the Muslim dominance of Delhi (and much of the Subcontinent) that was to endure until 1857. For Qutb-ud-Din, who died four years after gaining power, it marked the eastern extremity of the Islamic faith, casting the shadow of God over east and west. It was also a minaret, from which the muezzin called the faithful to prayer. Only the first storey has been ascribed to Qutb-ud-din’s own short reign; the other four were built under his successor Iltutmish, and the top was restored in 1369 under Firoz Shah, using marble to face the red sandstone.
The Quwwat-ul-Islam mosque
Adjacent to the tower lie the ruins of India’s first mosque, Quwwat-ul-Islam (“the Might of Islam”), commissioned by Qutb-ud-Din and built using the remains of 27 Hindu and Jain temples with the help of Hindu artisans whose influence can be seen in the detail of the masonry and the indigenous corbelled arches. Steps lead to an impressive courtyard flanked by cloisters and supported by pillars unmistakeably taken from a Hindu temple and adapted to accord with strict Islamic law forbidding iconic worship – all the faces of the decorative figures carved into the columns have been removed. Especially fine ornamental arches, rising as high as 16m, remain of what was once the prayer hall. Beautifully carved sandstone screens, combining Koranic calligraphy with the Indian lotus, form a facade immediately to the west of the mosque, facing Mecca. The thirteenth-century Delhi sultan Iltutmish and his successors had the building extended, enlarging the prayer hall and the cloisters and introducing geometric designs, calligraphy, glazed tiles set in brick, and squinches (arches set diagonally to a square to support a dome).
Alai Minar
The Khalji sultan Ala-ud-Din had the mosque extended to the north, and aimed to build a tower even taller than the Qutb Minar, but his Alai Minar never made it beyond the first storey, which still stands, and is regarded as a monument to the folly of vain ambition. Ala-ud-Din also commissioned the Alai Darwaza, an elegant mausoleum-like gateway with stone lattice screens, to the south of the Qutb Minar.
The Iron Pillar
In complete contrast to the mainly Islamic surroundings, an Iron Pillar (7.2m) stands in the precincts of Qutb-ud-Din’s original mosque, bearing fourth-century Sanskrit inscriptions of the Gupta period attributing it to the memory of King Chandragupta II (375–415 AD). Once topped with an image of the Hindu bird god, Garuda, the extraordinarily pure but rust-free pillar has puzzled metallurgists. Its rust resistance is apparently due to its containing as much as one percent phosphorous, which has acted as a chemical catalyst to create a protective layer of an unusual compound called misawite around the metal. The pillar was evidently transplanted here by the Tomars, but it’s not known from where.

I just wanted to show off three gems of different sizes in this pic. It boils down to experimenting with a depth of field that isn't all-inclusive versus one that is. Personally, this one could be better. I think that if I were to re-shoot this, I would definitely go for a deeper depth of field rather than such a shallow one.
Maybe when I decide to do some re-shoots of my favorite shots, it'll happen.
