Web15 dec. 2024 · Abell 2744 is a cluster of galaxies 5 million light-years across and 3.5 billion light-years away. Its immense mass has warped space, magnifying and distorting light from galaxies beyond the cluster, and giving us a view into the universe as it existed more than 13 billion years ago. WebGalaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest have trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years. Most large galaxies have supermassive black holes at their centers, some ... northern air cargo hazmat
