![]() ![]() “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 in Rome, in a statement. These clouds were created when shock waves from the explosion heated surrounding gas to incredibly high temperatures, accelerating high energy particles called cosmic rays. Glowing purple gas clouds can be seen around the remains of the star. The images offer a glimpse of Cassiopeia A, the famous remnant of a supernova, or exploding star. Just over two months after launching to space, NASA’s newest explorer - the Imaging X-Ray Polarimetry Explorer, or IXPE – shared its very first images.Īnd they are stunning. This website provides information to air carrier crew members about radiation exposure while flying.A new pair of X-ray eyes on the universe is allowing us to see extreme objects like never before. The AFA-CWA provides information for flight attendants, like information about in-flight radiation.

NOAA’s Space Weather Prediction Center – Space Weather Toolkit NOAA studies a variety of different topics, including space weather, like sunspots and other solar events. ![]() Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA) This technical document provides information on the FAA's Solar Radiation Alert System. Solar Radiation Alert System (PDF) (28 pp, 977 K, About PDF) This webpage contains links to several articles about radiation and airline travel and a link to CARI-6 and CARI-6m, the FAA's cosmic radiation dose calculators. The FAA tracks solar radiation, since it can interfere with some instrumentation onboard aircraft. Cosmic radiation makes up only a small portion of the radiation that we are exposed to every year. Cosmic radiation is part of the natural radiation that we are exposed to all the time. The FAA also developed a computer software program that estimates radiation exposure from flights. During solar events, the FAA sends out a Solar Radiation Alert so pilots can fly at lower elevations to reduce exposure. The Federal Aviation Administration (FAA) tracks crew members’ exposure to cosmic radiation and uses a long-term calculation to estimate their total dose. However, airline crew members need to consider their flying time more carefully. Most people do not fly frequently enough to add a significant amount to their total radiation dose. In the United States, the average dose of radiation people receive is 620 mrem (6.2 mSv) per year. ![]() If you are curious about your estimated dose of radiation from ionizing radiation, please visit our Dose Calculator. The radiation from two cross-country flights is about equal to the radiation dose from a single chest x-ray. If we take a one-way flight across the country (New York to Los Angeles), we likely receive 2-5 millirem (mrem), or 0.02-0.05 millisieverts (mSv), of radiation. Two of the most important factors are altitude and length of the flight. The amount of cosmic radiation we receive during flights depends on many things. With less atmosphere to protect us, we are exposed to more cosmic radiation than when we are standing on the ground. When we fly in an airplane, we are closer to outer space.
