The beautiful demoiselle (Calopteryx virgo) is a European damselfly belonging to the family Calopterygidae. It is often found along fast-flowing waters where it is most at home...Calopteryx virgo can reach a body length of 49–54 millimetres (1.9–2.1 in), with a length of hindwings of 31–37 millimetres (1.2–1.5 in). These large, dark damselflies have small hemispherical eyes located laterally on the head, two pairs of wings similar in shape and a slender abdomen
Un breve encuentro con esta especie en los bordes del río, cuyas aguas corrían rápidas a la sombra de los árboles y que hacían mecer a las plantas de las orillas en que se posaban los escasos machos de Calopteryx virgo. Complicado fue sacarle alguna toma medio decente, pero se disfrutó de sus verdosos y azulados tonos metálicos.

Calopteryx virgo, ♂
A brief encounter with this species on the edges of the river, whose waters ran fast in the shade of the trees and made the plants of the banks on which the few Calopteryx virgo males settled. Complicated was to take a decent half shot, but he enjoyed his green and blue metallic tones.

The blue galaxy located to the right is NGC 4536, an Intermediate Spiral Galaxy in the Virgo constellation. It is close to the celestial equator and is partly visible from both hemispheres. NGC 4536 is undergoing strong burst formation. Based on X-ray emission from the core, it may contain a small supermassive back hole. It is 50 million light-years away and has an apparent magnitude of 11.1.
The small galaxy closer to the centre is NGC 4533. It has a surface brightness of 23.04 mag/arcsec and is 1.82 X 0.389 arcmin.
The galaxy to the left is NGC 4527. It has an angular size of 6.3 X 1.3 arcmin. Its classification is an Intermediate Spiral (Hubble galaxy morphological classification), similar to the Andromeda Galaxy. It is about 48.9 million lightyears away.

The beautiful demoiselle (Calopteryx virgo) is a European damselfly belonging to the family Calopterygidae. It is often found along fast-flowing waters where it is most at home...The distribution of the beautiful demoiselle covers all of Europe with the exception of the southwestern Iberian Peninsula, the Balearic Islands and Iceland.
Calopteryx virgo, le caloptéryx vierge (anciennement l'agrion vierge) est une espèce d'insectes odonates du sous-ordre des zygoptères ou demoiselles, qui fait partie d'une famille qui ne comprend, en Europe, qu'un seul genre, Calopteryx1.
the astrological sign of virgo is an earth sign and symbolized by "the virgin goddess of justice" in
greek mythology.
virgos tend to be perfectionists but are also known for being practical, shy, cautious and calm.. on the negative side they can be very critical and judgmental.
ooops! i let the dates slip by and forgot to do my virgo astrological image in the actual correct time frame..my aplogies to my virgo friends!!! happy belated b-day! :)
for my friend craig.. happy belated b-day !!!
ps- unfortunately i finished this image before doing more research on virgo and discovered that she should be holding wheat.. oh well.. i did find images of her holding a shield and sword.. so i'm sticking with the greek explanation i guess :)
special thanks to joessistah for the wings

C. virgo è una specie europea con i limiti della sua distribuzione nel nord della Finlandia e nel sud dell’Italia continentale. In Italia la specie è comune sopratutto nelle zone di bassa montagna, fino a 800 m di quota. E’ conosciuta di tutte le regioni con l’eccezione della Valle di Aosta e Puglia. Per la Sicilia e Sardegna esistono solo antiche e dubbie segnalazioni.

Centaurus A, also known as NGC 5128, is a peculiar lenticular galaxy in the constellation Centaurus, which appears to be an elliptical galaxy with a huge superimposed dust lane. It is one of the closest radio galaxies, and its active galactic nucleus has been extensively studied.
Discovery and Identity
NGC 5128 was discovered by James Dunlop on August 4, 1826. John Herschel was next to see it, from South Africa in 1834; he cataloged it as h 3501, which became GC 3525 in his General Catalogue of 1864, and NGC 5128 in J. L. E. Dreyer's New General Catalog. Herschel was first to note this galaxy's peculiarity, in 1847.
Halton Arp included NGC 5128 in his 1966 Atlas of Peculiar Galaxies as one of the best examples of a "disturbed" galaxy with dust absorption.
Amateur Observation
Centaurus A appears approximately 4° north of the naked-eye globular cluster Omega Centauri. At magnitude 7.0, this galaxy is the fifth brightest in the sky, making it ideal for observation, although it is only visible from the southern hemisphere and low northern latitudes. Centaurus A has been spotted with the naked eye by expert observers under very good conditions. The bright central bulge and dark dust lane are visible in finderscopes and large binoculars, and additional structure may be seen in larger telescopes.
NGC 5128 is a "lenticular" galaxy, of intermediate type between elliptical and disk (spiral) galaxies. Its main body has all characteristics of a large elliptical, but a pronounced dust belt is superimposed over the center, forming a disk plane around this galaxy.
The only supernova discovered in Centaurus A so far is SN 1986G, a Type Ia event that reached mag 12.5 in May, 1986.
Properties and Evolution
Centaurus A is located about 11 million light-years away, at the center of one of two subgroups within the Centaurus A/M83 Group. Messier 83 (the Southern Pinwheel Galaxy) is at the center of the other subgroup. These two groups are sometimes identified as one, since the galaxies around Centaurus A and the galaxies around M 83 are physically close to each other, and both subgroups appear to be stationary relative to each other. The Centaurus A/M83 Group is part of the Virgo Supercluster.
NGC 5128's strange morphology is the result of a merger between two smaller galaxies. The bulge of Centaurus A is comprised mainly of evolved red stars. Its dusty disk, however, has been the site of more recent star formation; over 100 star formation regions have been identified in the disk. As observed in other such "starburst" galaxies, a collision is responsible for the intense star formation. Scientists using the Spitzer Space Telescope have confirmed that Centaurus A is an elliptical galaxy going through a collision, devouring a spiral.
In the radio part of the spectrum, Centaurus A exhibits two vast regions of radio emission, running along the polar axis of NGC 5128's disk and extending hundreds of light years in both directions. A relativistic jet from what is believed to be a supermassive black hole at the center of the galaxy is responsible for emissions in the X-ray and radio wavelengths. Radio observations of the jet indicate that the inner parts of the jet are moving at about 1/2 the speed of light. X-rays are produced farther out, as the jet collides with surrounding gases, creating highly energetic particles.

Thank you everyone who has taken the time to view, fave or comment on my photo. It is very much appreciated.
25/06/2023, at anchor, Longyearbyen, Svalbard, Spitsbergen, Norway.
The former Sjöfartsverkets (Swedish Maritime Administration) buoy/lighthouse tender 'Fyrbyggaren', which was converted in 2021 to a passenger 'expedition' vessel for use in the Arctic region.
Owned and operated by Virgo Rederiaktiebolaget of Partille, Sweden.
Built in 1976, and commissioned on 14/12/1976 by Sigbjørn Iversen Mekaniske Verksted AS, Flekkefjord , Norway (40)
655 g.t. & zero dwt.
Length x breadth x depth =
41,81m x 10,19m x 3,98m., as
'Fyrbyggaren' to 2021, and
'Virgo' since.
**16/06/2022, vessel ran aground in Fuglefjorden, north-western Spitzbergen, Svalbard, Norwegian archipelago between Norway and North Pole, Arctic, at around 10:00 UTC on June 14th.
There were 13 passengers and seven crew on board.
The ship’s hull was reported as breached in the area of its fuel tank and an oil leak was reported.
As of 15:00 UTC June 14th the vessel appeared to have been refloated and to be manoeuvring at very slow speed near the grounding site, with a tug and auxiliary vessel nearby.
Subsequently repaired and returned to service.**

here comes another astrological sign for my latest series.
i'm not totally satisfied with this picture, but it's so hot today that i really don't feel like remaking it
