Die Dreiecksgalaxie M33 ist, nach dem Andromedagalaxie M31, die zweithellste Spiralgalaxie am Nachthimmel und eine der uns nächstgelegenen.
Sie ist unter normalen Bedingungen nicht freiäugig, sondern nur mit dem Fernglas sichtbar.

Die Andromeda Galaxy M31 vom 19.09.2020. Eigentlich war die Aufnahme nur ein Setup- und Autoguiding Test. Jetzt habe ich die Aufnahme dafür benutzt um in Pixinsight und Photoshop etwas zu üben. Mit dem Ergebnis bin ich trotz der kurzen Belichtungszeit eigentlich recht zufrieden.

"In the beginning, nearly fourteen billion years ago, all the space and all the matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the period that ends this sentence."

Astronomical Institute is with a dome at the top of the highest, three-storied building (photo). The dome contains 20-cm Clark-Repsold refractor.
There are two departments in the Institute:
- Department of Astrophysics and Classical Astronomy
- Department of Solar Physics and Space Science.
Tasks of the Institute:
Bialkow Observatory, which is a part of the Institute, works as one of the five professional observatories in Poland. There are actually two professional instruments in the observatory: 60-cm reflector and 53-cm coronograph. Observing staff takes part in the international programs and observational campaigns observing both the Sun and stars.
NGC 281 oder auch Pac-Man-Nebel ist ein Emissionsnebel im Sternbild Kassiopeia, welcher 9500 Lichtjahre von der Erde entfernt ist. In NGC 281 ist der offene Sternhaufen IC 1590 eingebettet, dessen Sterne um das Zentrum des Nebels verstreut sind und einige von ihnen durch ihre Röntgenstrahlung hervortreten.

The Einstein Tower (German: Einsteinturm) is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany built by architect Erich Mendelsohn.
It was built on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate (or disprove) Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924.
Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam. Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory.

Castle in the snow
A great view of the Cheshire Plain looking nice and green, no snow! But at Mow Cop Castle and village it's a different story. Plus, over my shoulder to the right, looking south is my county of Staffordshire and it looks like a winter wonderland!
Info.
Over looking the Cheshire plain to the north with views the Jodrell Bank Observatory which is a British observatory that hosts a number of radio telescopes, and is part of the Jodrell Bank Centre for Astrophysics at the University of Manchester.
Circa 1754.
Some have suggested that the Romans built a beacon or watchtower on this site during their occupation of England. This idea is be supported by the fact that the Romans had a small camp at Bent Farm, Astbury. The Romans did build a road from Bent Farm through to Biddulph via the ‘Nick O Th Hill’ this would have bought them very close to Mow Cop. There is coal, millstone grit, and limestone in the area, all of which the Romans would have used.
This is also part of the Gritstone Trail, a 35 mile/56 km trail through Cheshire's Peak District.

The Polar Night Nitric Oxide or PolarNOx experiment from Virginia Tech is launched aboard a NASA Black Brant IX sounding rocket at 8:45 a.m. EST, Jan. 27, from the Poker Flat Research Range in Alaska. PolarNOx is measuring nitric oxide in the polar night sky. Nitric oxide in the polar night sky is created by auroras. Under appropriate conditions it can be transported to the stratosphere where it may destroy ozone resulting in possible changes in stratospheric temperature and wind and may even impact the circulation at Earth’s surface.

Radio Telescope Submillimeter Array (SMA) on Mauna Kea, Big Island.
SMA Project Website: "The Submillimeter Array (SMA) is an 8-element radio interferometer located near the summit of Maunakea in Hawaii. Operating at frequencies from 180 GHz to 420 GHz, the 6 m diameter dishes may be arranged into configurations with baselines as long as 509 m, producing a synthesized beam of sub-arcsecond width. Each element can observe with two receivers simultaneously, with up to 8 GHz bandwidth each per sideband. The digital correlator backend provides a uniform resolution as high as 140 kHz.
The Submillimeter Array is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics and is funded by the Smithsonian Institution and the Academia Sinica."

So exegetically we may read the “darkness on the face of the deep” as that darkness from which at another moment Elohim differentiates the light: “God separated the light from the darkness” (1: 4). In other words the original dark is also original light, a depth that contains both darkness and light, or more precisely, transcends that distinction: it would be none other than the “luminous dark.” It is like a picture of the immensity of the universe—vast darkness indeed—through which ripple invisible waves of light-energy. Only with certain instruments, or within the galactic neighborhoods of stars, as with our sun, can the light be distinguished. But Genesis is a theopoetics, not an astrophysics, of light born from this dark.
