Astronomers have found a pulsating dead star beaming with the energy of about 10 million Suns, which is the brightest pulsar ever recorded.. A rare and mighty pulsar (pink) can be seen at the center of galaxy M82 in this new multi-wavelength portrait. NASA’s NuSTAR mission discovered the “pulse” of the pulsar — a type of dead star — using is high-energy X-ray vision.

The term Higgsogenesis refers to the first appearance of Higgs particles in the early universe, just as baryogenesis refers to the appearance of baryons (protons and neutrons) in the early moments after the big bang. While baryogenesis is a fairly well understood process, Higgsogenesis is still very hypothetical. (Credit: CERN/Lucas Taylor, Koberlein)

The image above shows a graphic which was produced by the SETI from the data of the Wow signal. A signal (Gaussian, triplet or pulse) arises only in a single narrowband channel. All other channels contain noise. Up to now we do not know cosmic phenomena which would generate such signals. It would seem improbable that they have no artificial origin. The picture shows a computer generated example of a strong Gaussian signal.

This quirk of subatomics could have huge implications for our understanding of the universe, specifically how the current inequality between matter and antimatter came to be. Answering that could, in turn, provide a better insight as to why reality did not simply blink out of existence immediately after the Big Bang as a universe’s worth of matter and antimatter negated one another’s existences (Credit: Tarantola, Fermilab, )

Gas column density 5 Myr after stars begin forming in the “real” Clouds (left panels) and corresponding Spheres (right panels). The Spheres begin forming stars 5-6 Myr after t=0, so the figure shows simulations at a similar stage of star formation. Clouds show more widespread star formation, and alignment of their major gas filaments along the larger-scale structures present in the galaxy. (Credit: Rey-Raposo, Dobbs & Duarte-Cabral 2014)

German winner of the Nobel Prize for chemistry Stefan Hell gestures at a small party with his colleagues in Goettingen, Germany, Wednesday, Oct. 8, 2014. Hell shares the prize with Americans Eric Betzig and William E. Moerner for developing ways to dramatically improve the resolution of optical microscopes. Hell developed the underlying technology for R&D 100 Awards-winning super-resolution microscopes from Leica. (Credit AP/dpa, Swen Pfoertner)

if we have a system of qubits all in the same state (with the same probability distributions), we have identical qubits, even though we might get different results upon measuring the individual qubits. Strangely enough, particles in the quantum world can be both identical and distinct at the same time. (Credit: M. Byrne)
This composite X-ray/radio image of Abell 400 shows radio jets (pink), immersed in a vast cloud of multimillion degree X-ray emitting gas (blue) that pervades the cluster. The jets emanate from the vicinity of two supermassive black holes (bright spots in the image) in the galaxy. Chandra and radio data confirm that the unusual structure is due to the merger of two large galaxies, whose supermassive black holes are bound together by their mutual gravity.

There is no doubt in my mind that society invests its billions well if it invests in theoretical physics. Whether that investment should go into particle colliders though is a different question. I don’t have a good answer to that, and I don’t see that the question is seriously being discussed. (Credit: Hossenfelder)
