It started out as an avoiding-the-gnats leg-stretcher, then turned into a pretty darn nice hike. How often do you get the chance to hike under a bright spiral nebula?

June 21st: The gnats at Cedar Mesa Campground were exemplary. F***ing CLOUDS of them.
They'd been practically everywhere we'd been for this leg (the "dry side") of the trip, they were the topic of discussion with anybody that could stand still without being swarmed for long enough to talk. Nobody had seen a year like this for gnats, and NOTHING was working to keep them away. Those with enough forewarning had brought mesh headgear, that actually worked until you wanted to eat something... We'd brought two different kinds of OFF, neither had any effect. We debated bagging this part of the trip entirely but neither of us wanted to be beaten by an insect almost too small to see, and when would we be back if we left now? So we set up the tent and employed the best defense we could: Keep Moving.
Spiral Nebula by Geoffrey Clarke, 1962 in front of the Herschel Building, University of Newcastle.
"Standing in front of the Herschel Building is an important post-war 20th century sculpture. Spiral Nebula by Geoffrey Clarke RA is a monumental and striking example of the artist’s work and one of few examples from this period sited in a public location in Newcastle upon Tyne.
Spiral Nebula was commissioned in 1962 by the architect, Sir Basil Spence, for the grounds of the Herschel building. Spence often worked collaboratively with Clarke, and Spiral Nebula compliments the building’s modernist architecture. On first view, the sculpture appears to be constructed out of wooden slats, however closer inspection reveals a steel structure with painted cast aluminium panels. Viewed in relation to the then new physics building’s use; the sculpture can be taken as a symbol of scientific advances in the 1960s. Yet, the sculpture caused a dispute between Clarke and Spence. It is understood Spence thought its waxed finish distracted attention from the building and a month after unveiling, the sculpture was flame blasted and painted grey.
Over the past 50 years, the sculpture’s surface and structural condition has inevitably degraded. As custodian of this innovative sculpture, the University embarked on conservation work to ensure it can be appreciated for many years to come. This will allow audiences to appreciate the original condition and concept of Clarke’s Spiral Nebula along with relocating it to an improved position within the Herschel quadrangle. Missing aluminium panels will be re-cast using Clarke’s lost polystyrene process and cleaning will remove the grey paint from the surface, restoring the sculpture to its former glory.
Spiral Nebula comprises a steel armature with aluminium cast from polystyrene which Clarke carved with a heated instrument. The polystyrene was packed into fine sand and vaporised as molten aluminium was poured in, hardening to take the same shape. This was an adaptation of the lost wax method with Clarke the first artist in the world to use it."

Mais uma captura de uma Nebulosa planetária, essa em formato de S, a NGC 5189. Nebulosas planetárias nada mais são que os últimos suspiros de uma estrela que não morrerá em uma supernova. Ela expele suas camadas externas conforme a fusão nuclear perde força e seus elementos ficam mais e mais pesados. O formato que os jatos de matéria são expelidos por elas varia, mas normalmente são circulares. É uma nebulosa bem brilhante, considerando o pouco tempo de exposição e nível de detalhes que consegui.

Another planetary nebula. This time, in a S shape, the NGC 5189. Planetary nebulae are the last breath of stars that won't die in a supernova. It external layers are expelled as the nuclear fusion on its core become more slow and produces heavier elements. The matter jets can take many shapes, but usually they are circular. It's a bright nebula, considering the exposure time that I took and the details I got. Picture taken on 08/05/2021 in bortle 3 site, o @bregildo_camping

"‘Spiral Nebula’ by noted post-war sculptor Geoffrey Clarke, and located outside the Herschel Building, is a leading example of post-war public art and one of the few from this period in Newcastle.
It was commissioned in 1962 as part of the design of the Herschel Building for the University’s Physics Department, and reflects the scientific advances being made at the time - Britain’s first satellite, Ariel 1, was launched in the same year the building was opened and the sculpture unveiled.
Spiral Nebula has the appearance of being constructed from wooden slats but Clarke used a pioneering technique to create it. Using aluminium rather than traditional bronze, Clarke adapted the long-established 'lost wax' method by carving polystyrene moulds with a heated instrument and then casting molten metal, which vaporised the polystyrene.
Yet, when the sculpture was unveiled, it caused a dispute between Clarke and Sir Basil Spence, the architect responsible for the Herschel Building as Spence thought that its waxed finish distracted attention from the building. A month later, the sculpture was flame-blasted and painted grey.
By 2012, the sculpture was in a deteriorating condition and Newcastle University undertook a conservation plan to return the sculpture to Clarke’s original vision. This involved consulting with Clarke, who stipulated that his son, Jonathan, also a sculptor, work on the restoration along with Andrew Pawsey, son of Clarke’s original assistant who helped him create Spiral Nebula in 1962.
