How do we map the gamma-ray sky? We take 7,464,664 gamma rays collected by the Fermi LAT over 12 years and turn that into a brightness map with a blue-orange-yellow color scale that best illustrates the sources. What crayons would you use to color Fermi's sky? #FermiFriday | NASA Universe

Scientists are still learning from a 2022 gamma-ray burst nicknamed the BOAT, or “brightest of all time.” A study of the first few minutes of this burst found an important feature not seen before, a narrow band of enhanced brightness called an emission line. This could help us understand more about the powerful jets these blasts produce. Watch this video to learn more, and click here for more information: https://go.nasa.gov/4cWx2uj | NASA Universe
