Quasar J0742+2704 (center) became the subject of astronomers’ interest after it was discovered to have a newborn jet blasting from the disk around its supermassive black hole in 2020, using the Karl G. Jansky Very Large Array (VLA) radio observatory. This led to follow-up with other observatories in an effort to determine the properties of the galaxy and what may have triggered the jet.
While the jet itself cannot be seen in this NASA/ESA Hubble Space Telescope infrared-light image, the spiral shape of J0742+2704 is clear, with faint but detectable arms branching above and below the galaxy center. This was a big surprise to the research team, as quasars hosting jets are typically elliptical-shaped, and it is suspected that messy mergers with other galaxies are what funnel gas toward the black hole and fuel jets. These mergers would also disrupt any spiral formation a galaxy may have had before mixing its contents with another galaxy.
Though its intact spiral shape means it has not experienced a major merger, Hubble does show evidence that its lower arm has been disrupted, possibly by the tidal forces of interaction with another galaxy. This could mean that jets can be triggered by a far less involved, dramatic interaction of galaxies than a full merger. The large galaxy to the lower right of the quasar appears to be a ring galaxy, another sign of interaction. Ring galaxies form after a small galaxy passes through the center of a larger galaxy, reconfiguring its gas and dust.
The brightest parts of this image — foreground stars and the bright center of the quasar — show the characteristic “starry” spikes produced by Hubble (and other telescopes’) interior structure. They are not actual aspects of the cosmic objects
[Image description: Field of yellow galaxies of various sizes and distances on a black background. Two larger galaxies are prominent. Centered is a galaxy with a bright core and faint spiral arms coming off its top and bottom. To the lower right of the spiral is a ring galaxy with an apparent gap between its bright core and the ring oval of dust and gas surrounding it.]

Richie Ramone and his band in Belfast last night. One of the best gigs I have been at in recent years. Very small venue, the Deer's Head on North Street. They are so good that they really should be playing to far bigger crowds. But the advantage of the small venue for me was that I could get the camera in easily and get it very close to the band.

good reliable eater - similar to Cox's Orange Pippin but less dificult to keep healthy and bigger apples.
I've passed this abandoned schoolhouse many times, but the trees and brush were so overgrown i could'nt get a good photo of it.
Thie back of this building is even more decayed and run down!

Once a year the dead rise up and party. This year, at Leicester Square in London, I was at hand with my camera.
This is the old hospital on Hamilton AFB in Novato. It's all boarded up and starting to crumble now. I think it's been sold for development into an elderly care facility, but that was two years ago, so who knows!
Before the windows were boarded up, a nurse was rumored to be seen at the windows, decades after the base and hospital were closed. This makes it a perfect place to walk Shy, but so far no pics of ghosts I'm sad to report!

Paul Gauguin or Eugène Henri Paul Gauguin (1848–1903) was one of the most influential Post-Impressionist artists. Gauguin's experimental use of color and stark contrasts spearheaded the Synthetism movement, which regarded form and color as equally important. Most of his paintings depict people or landscapes from French Polynesia since he spent many years in that region in search of inspiration. His artistic experiments influenced many avant-garde movements in the early 20th century as well as modern artists such as Pablo Picasso and Henri Matisse. We have digitally enhanced some of his notable works that are now in the public domain and made them available for you to download under the creative commons 0 license.

Here on Paradise Bay on an Island you'll find the semi-abandoned research station of the Argentineans. It's interesting to look out over the vastness of the great white continent and be surprised by a splash of blue and red. Humans leave ourselves everywhere.

Seies Z7100 EMUs dating back to the early 1960s comprised of a power car (closest to the camera) and loose trailers rather than fixed formed sets. Based at Vénissieux depot in the suburbs of Lyon, these worked over much of the line through Avignon and along the coast to the Spanish border. Seen at the frontier station of Cerbère on 9 April 1987, Z7118 forms the 14:48 departure to Perpignan.
