I was blown away by the colors of the sideboard of this hotel. But when I stopped, I realized that I could divide the subject passing by through the two types of reflections. Although I made several shots this is the chosen one
On 10 December, ESA’s XMM-Newton X-ray space observatory is celebrating its 20th launch anniversary. In those two decades, the observatory has supplied a constant stream of outstanding science. One area that the mission has excelled in is the science of black holes, having had a profound effect on our understanding of these cosmic enigmas.
Black holes are celestial objects so dense that nothing, not even light, can escape their pull. In this artist’s impression, the weird shapes of light around the black hole are what computer simulations predict will happen in the vicinity of its intense gravitational field.
Although neither XMM-Newton nor any other telescope can actually see black holes in this detail, the mission’s data and observations have provided a great source of information about these mysterious gravitational traps. In particular, XMM-Newton has been particularly good at isolating the X-rays given out by high-temperature, ionised atoms of iron as they swirl towards doom in the black hole.
The X-rays given out from the iron contain information about the geometry and dynamics of the black hole. In 2013, XMM-Newton was used to measure such emission in order to study the rotation rate of the supermassive black hole at the centre of the spiral galaxy NGC 1365.
Supermassive black holes, with masses between millions and billions of times the mass of our Sun, are thought to lurk in the centre of almost every large galaxy in the Universe. Their rotation rate is important because it can give away important details about the history of their host galaxy.
A fast rotating black hole is fed by a uniform stream of matter falling together, or by galaxies merging with one another, whereas a slowly rotating black hole is buffeted from all sides by small clumps of matter hitting it. In the case of NGC 1365, XMM-Newton showed that the black hole was rotating quickly and so the galaxy probably grew steadily over time, or merged with others.
More recently, XMM-Newton discovered mysterious flashes from the black hole at the centre of another galaxy called GSN 069. These flares took place every nine hours or so, raising the brightness of the X-ray emission by a factor of 100. These eruptions are thought to be coming from the matter caught in the black hole’s gravitational grip or from a less massive black hole circling the more massive one.
As XMM-Newton continues into its third decade, black holes and the galaxies they are found in will continue to be a priority target.

"X-ray Vision"
I kind of liked the idea of a double exposure being like an Xray. A way to show what's on the inside of us, aside from bones and things of course.
Nature, the forest and the trees and the fascinating rocks and mountains are certainly where my mind feels most at ease. I think if I could take the sort of xray that showed that feeling, it's certainly what would show.
What about you?

Revisiting techniques of graphic work using ink on X-ray and imaging documents. Transposing the material version into the virtual medium through a photo montage process involving composition, adjustments of colour, light and contrast.
A thin, gauzy dress is delightfully cool on a blazing hot day, but it seems the camera flash will penetrate it easier than the breeze. Should've brought a slip!
On my walk today I saw a teasel partly opened so I took one home and cut it half to photograph on X ray film (with my New Countess 10x8 camera from 1890). F45, 40s. Photographed and inverted in Photoshop Very pleased with the way this has come out

The grand finale of the universe’s light show🗽
The final image is of ZwCl 0024+1652 - a distant galaxy cluster in which astronomers have found evidence for dark matter by using specially processed data from Hubble (blue). Another image from Hubble reveals the individual galaxies in the cluster (appearing as yellow and white). X-ray data from Chandra shows the enormous reservoir of superheated gas that pervades this galaxy cluster (red) with much more mass than all the galaxies taken together.

Yes, that is my hand. I didn't feel a thing ;-) And no, the camera won't work since the battery has been removed for the radiograph.
