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)

The Einstein Papers Project, a group of scholars devoted to collecting and transcribing Einstein’s works and publishing The Collected Papers of Albert Einstein both online and in printed format, have collected thousands of Einstein’s letters, both those from him and to him. But this exchange is new. (Credit: The Telegraph)

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)

Our current model of the early inflationary period predicts that the universe should be flat, and so far that has held up. If the universe actually is curved, then the inflationary period must have been more complex than we have thought. (Credit: Koberlien)

Few scientists doubt that Einstein was right. But the mathematics describing the time-dilation effect are “fundamental to all physical theories”, says Thomas Udem, a physicist at the Max Planck Institute for Quantum Optics in Garching, Germany, who was not involved in the research. “It is of utmost importance to verify it with the best possible accuracy.” (Credit: A.

The illustration shows how oscillating photons create an image of frozen light. At first, photons in the experiment flow easily between two superconducting sites, producing the large waves shown at left. After a time, the scientists cause the light to ‘freeze,’ trapping the photons in place. Fast oscillations on the right of the image are evidence of the new trapped behavior.

The quasicrystals formed 4.5 billion years ago in a violent collision between two rocks, among the asteroids that coalesced into planets. The rock with the quasicrystals landed in Chukotka as a meteorite. “They’re part of the primal stuff that formed our solar system,” Dr. Steinhardt said. The above is A penteract (5-cube) pattern using 5D orthographic projection to 2D using Petrie polygon basis vectors overlaid on the diffractogram from an Icosahedral Ho-Mg-Zn quasicrystal.

When space probes, such as Rosetta and Cassini, fly over certain planets and moons, in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A researcher has now analyzed whether or not a hypothetical gravitomagnetic field could have an influence. However, other factors such as solar radiation, tides, or even relativistic effects or dark matter could be behind this mystery. An artist’s rendition of Rosetta probe during a flyby.
