Luck, Galaxies and insanity!!!


Good afternoon interweb,  and looking out of the window it most certainly is a very warm and pleasant afternoon.
I have not been in touch for a day or so as I had a bit of a mental wobble with regard to luck, or the lack of it. Things had been collecting, just little things the sort that on their own don’t really bother you but as they build up they begin to annoy the fuck out of you.
The straw that broke the camel’s back this time was a still not functioning Truck despite nearly £2000.00 been spent on it in the last two months.
I got pissed off and decided to take to my bed for the duration of the afternoon and evening.
This would have probably solved the issues had the bed not collapsed leaving me staring at the ceiling whilst leaning at a very uncomfortable angle onto the wrought iron frame of the bed.
Anyway normal service has since resumed and I would like to bring to you today a stunning photograph. 
 Not that remarkable I hear you cry, well when I tell you that what you can see here is not a few stars but around 200,000 galaxies.
The image was taken by The European Southern Observatory's VISTA telescope.
ESO's VISTA telescope has been trained on the same patch of sky repeatedly to slowly accumulate the very dim light of the most distant galaxies. In total more than six thousand separate exposures with a total effective exposure time of 55 hours, taken through five different coloured filters, have been combined to create this picture. This image from the UltraVISTA survey is the deepest infrared view of the sky of its size ever taken.
I have discussed in previous posts about the light from distant galaxies falling into the red part of the spectrum and VISTA makes the most of this. At first glance the UltraVISTA image looks unremarkable, a few bright stars and a sprinkling of fainter ones. But in fact almost all of those fainter objects are not stars in the Milky Way, but very remote galaxies, each containing billions of stars.
 Enlarging the image to fill the screen, and zooming in reveals more and more of them, and the image records more than 200 000 galaxies in total.
The expansion of the Universe shifts light from distant objects towards longer wavelengths.
 For starlight coming from the most distant galaxies that we can observe, this means that most of the light falls in the infrared part of the spectrum when it gets to Earth. As a highly sensitive infrared telescope with a wide field of view, VISTA is uniquely powerful for spotting distant galaxies in the early Universe. By studying galaxies in redshifted light at successively larger distances, astronomers can also trace how galaxies were built up and evolved over the history of the cosmos.
I find this shit really interesting which is why I blog about it but apologies to those that don’t, for you here is some drivel, Sometimes the appropriate response to reality is to go totally and unreasonably insane, a good listener is usually thinking about something else and remember, no matter where you go, there you are.
Peace out y'all, THE BAGSTAXXX
