    In 1610, Nicolas-Claude Fabri de Peiresc discovered the Orion Nebula using a telescope. This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659 by Christiaan Huygens, who also believed he was the first person to discover this nebulosity. [11]

    Pease 1 is a planetary nebula located within the globular cluster M15 33,600 light years away in the constellation Pegasus.It was the first planetary nebula known to exist within a globular cluster when it was discovered in 1928 [2] (for Francis G. Pease), and just four more have been found (in other clusters) since. [1]

    [25] [26] Hubble found Cepheids in several nebulae, including the Andromeda Nebula and Triangulum Nebula. His observations, made in 1924, proved conclusively that these nebulae were much too distant to be part of the Milky Way and were, in fact, entire galaxies outside our own; thus today they are no longer considered nebulae .

    The event had been under discussion for long time [7] [6] [19] but in 2021 another candidate was proposed for the remnant, the recently discovered nebula Pa 30 which has been found to be about 1000 years old.

    The nebula contains ions of extremely high ionization potential. [20] The helium hydride ion, thought to be the earliest molecule to have been formed in the Universe (about 100,000 years after the Big Bang), was detected in 2019 for the first time in space in NGC 7027. [21] [22] There is also evidence for the presence of nanodiamond in NGC 7027 ...
