New Faint Nebulas and Ionized Oxygen Discovered in Cassiopeia

Astronomers have revealed three previously hidden, faint nebulas and the presence of ionized oxygen in the Cassiopeia constellation, captured after 100 hours of observation with a special oxygen filter. These newly discovered 'blue phantoms,' designated Objects 1, 2, and 3, add to the known 'Ghosts of Cassiopeia' (IC 59 and IC 63), with their origins still under investigation.
