This composite image shows an intergalactic "weather map" around the elliptical galaxy NGC 5813, the dominant central galaxy in a galaxy group located about 105 million light years away from Earth. Just like a weather map for a local forecast on Earth, the colored circle depicts variations in temperature across a region. This particular maps presents the range of temperature in a region of space as observed by NASA's Chandra X-ray Observatory, with the hotter temperatures shown in red and decreasingly cooler temperatures shown in orange, yellow, green, and blue.
A notable feature of this image is the relatively small variation in temperature across the weather map, with a range of only about 30% across several hundred thousand light years. Without any sources of heat, the densest gas near the center of the map should cool to much lower temperatures as energy is lost because of radiation. However, regular outbursts generated by the supermassive black hole at the center of NGC 5813 provide heat, preventing the gas near the center of the galaxy from cooling to such low temperatures. This decreases the amount of cool gas available to form new stars. This process is analogous to the sun providing heat for Earth's atmosphere and preventing water and water vapor from cooling and freezing.
How do outbursts generated by the black hole provide heat? Powerful jets produced as gas swirls toward the black hole push cavities into the hot gas and drive shock waves -- like sonic booms -- outwards, heating the gas. The shocks from the most recent outburst, which occurred about 3 million years ago in Earth’s time frame, show up as a "figure eight" structure at the center of the image. This is the first system where the observed heating from shocks alone is sufficient to keep the gas from cooling indefinitely. These shocks allow the relatively tiny black hole to heat the huge area surrounding it, as shown here.
The gas around NGC 5813 shows evidence for three distinct outbursts from the black hole, which occurred 3 million, 20 million and 90 million years ago, in Earth's time frame. The average power of the two most recent outbursts differ by about a factor of six, showing that the power delivered by the jets can vary significantly over timescales of about 10 million years.
A paper describing these results has been accepted for publication in the Astrophysical Journal. The first author of the paper is Scott Randall from the Harvard-Smithsonian Center for Astrophysics (CfA) and the co-authors are Bill Forman from CfA; Simona Giacintucci from CfA and INAF in Bologna, Italy; Paul Nulsen from CfA; Ming Sun from the University of Virginia; Christine Jones from CfA; Eugene Churazov from the Max Planck Institute for Astrophysics in Garching, Germany and the Space Research Institute in Moscow, Russia; Larry David and Ralph Kraft from CfA; Megan Donahue from Michigan State University; Elizabeth Blanton from Boston University; and Aurora Simionescu and Norbert Werner from Stanford University.

Looks like a face to me. I seem to be way in to the mirror thing right now.Kinetic photography. but hay it is fun. Photo made from motion and things flying in a room. then add a bit of photo shop and fun things start to happen. what do you think.

[Part 4]
Nightfall had already arrived by the time Franz reached this mysterious destination. What Franz was seeing was beyond anything that he could've imagined. There wasn't just a solitary building, but a completely different world than his own. But of course, the bigger picture is always initially lost in the eyes of a little boy. “Holy moly,” Franz exclaimed, “look at all these pretty colors.” “Fritz would never believe I seen such fancy looking lamps.” Slowly stepping through the threshold of these neon lights, Franz noticed that no one, or no being, appeared to be around. Every once in a while, he would seem to notice a person or two; but those visions would quickly disappear. While wandering through this new world, he notices an area full of goods and supplies. "Merchant of Venus?" Franz wondered. He procedes to enter....
The End.
...Gotta love a Coen Brothers' inspired ending. ;)
... And if anyone was wondering what was with the 'unique' posting week; I was making up a story for a shot that I didn't think was all that strong. And looking at some of the photos I was also working with at the time, I realized they could all be blended in a story atmosphere; even with a stretch or two. I can't promise this coincedence won't happen again though.

I've shot the local Galaxies a number of times, but this is one of my favourite attempts. Not sure if I should have cropped so close to the wheel rim, though. I was trying to keep a letterbox type of aspect ratio.

She came from another universe, being sent down to help the humans of earth understand that their messing up their universe is in reality messing up the ENTIRE Universe.
Can she make the changes necessary before there is intergalactic caos in all the universe.

Some modern sculptures really leave the interpretation wide open.....! My friend here was hitching a ride at the local Intergalactic portal... The bright light and orange glow in the background is from the Crescent Moon as it was setting in the North Atlantic.

The generally cloudy weather of recent weeks gave few possibilities for imaging, so on the odd cloudless evening, I will tackle a subject that I can capture in a single evening.
The image is of NGC 2419, The Intergalactic Wanderer, a globular cluster that has proved to be something of an enigma to understand. It was discovered by William Herschel on December 31, 1788, and it differs from most other globular clusters in that it is so distant from the centre of the galaxy that it was thought to be not in orbit about the galaxy and thus earned the nickname 'The Intergalactic Wanderer'.
Studies of it now reveal that its orbit takes it out beyond the Magellanic Clouds and it takes three billion years to make one trip around the galaxy. It is at a distance of about 300,000 light-years from the solar system and at the same distance from the galactic centre. It presents a dim disc 4.5' across and has a magnitude of around 10. The brightest foreground stars in this image are around magnitude 8 but the brightest individual stars in the cluster itself are around magnitude 15.
The data comprise 15 x five-minutes of RGB captured on the evening of 5th February 2021.
Telescope: 200mm Ritchey-Chretien at 1660mm focal length
Camera: QSI 683 with Astrodon filters and a Lodestar as an off-axis guide camera
