Written by Michael Allen An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer), has challenged our understanding of what happens to matter in the direct vicinity of a black hole. With IXPE, astronomers can study incoming X-rays and measure the polarization, a property of light that describes the direction of its electric field. The polarization degree is …

Demonstration of first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries In a breakthrough for antimatter research, the BASE collaboration at CERN has kept an antiproton – the antimatter counterpart of a proton – oscillating smoothly between two different quantum states for almost a minute while trapped. The achievement, reported in a paper published today in the journal Nature, marks the …
