12/19/2023 0 Comments Nasa news today 2022![]() ![]() IXPE launched on a Falcon 9 rocket from Cape Canaveral, and now orbits 370 miles (600 kilometers) above Earth’s equator. The mission is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. We’re looking forward to what we’ll find as we analyze all the data.” “To fill in some of those details, we’ve developed a way to make IXPE’s measurements even more precise using machine learning techniques. “IXPE’s future polarization images should unveil the mechanisms at the heart of this famous cosmic accelerator,” said Roger Romani, an IXPE co-investigator at Stanford University. This will reveal new clues about how X-rays are produced at Cassiopeia A. ![]() Researchers are currently working with the data to create the first-ever X-ray polarization map of the object. With polarization data from Cassiopeia A, IXPE will allow scientists to see, for the first time, how the amount of polarization varies across the supernova remnant, which is about 10 light-years in diameter. “The IXPE image of Cassiopeia A is bellissima, and we look forward to analyzing the polarimetry data to learn even more about this supernova remnant,” said Paolo Soffitta, the Italian principal investigator for IXPE at the National Institute of Astrophysics (INAF) in Rome. ![]() IXPE’s instruments also measure the energy, the time of arrival, and the position in the sky of the X-rays from cosmic sources. The polarization of light contains clues to the environment where the light originated. “It demonstrates IXPE’s potential to gain new, never-before-seen information about Cassiopeia A, which is under analysis right now.”Ī key measurement that scientists will make with IXPE is called polarization, a way of looking at how X-ray light is oriented as it travels through space. Weisskopf, the IXPE principal investigator based at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The IXPE image of Cassiopeia A is as historic as the Chandra image of the same supernova remnant,” said Martin C. Colors ranging from cool purple and blue to red and hot white correspond with the increasing brightness of the X-rays. This image from NASA’s Imaging X-ray Polarimetry Explorer maps the intensity of X-rays coming from the observatory’s first target, the supernova Cassiopeia A. ![]()
