nebulae

Yes, some stars do just that, becoming clouds of ionized hydrogen we term nebulae.

Time for Yesterday A. C. Crispin 1990

Working from the Mt. Wilson observatory that looms in the distance over Los Angeles, they discovered that the blurry patches of light called nebulae were not mere gas clouds within the Milky Way, as long supposed, but galaxies in their own right.

Fifty years ago it was thought that in the heavenly bodies called nebulae the material of which the world was made had been discovered.

They have found within the limits of our astral system, and generally in its outer fields, a great number of objects which, from their foggy appearance, are called nebulae; some of vast extent and irregular figure, as that in the sword of Orion, which is visible to the naked eye; others of shape more defined; others, again, in which small bright nuclei appear here and there over the surface.

They believed the "nebulae" they were viewing were star clusters and gas clouds within the Milky Way. 85 years ago Edwin Hubble postulated, and proved, that these nebulae were distant galaxies and our Milky Way was one of an incalculable number of galaxies comprising the universe.

Cepheid variables located within them as standard candles to determine their distance, showing the "nebulae" were too distant to be part of the Milky Way and hence other galaxies.

The concept of this book - and of the series - is to present an up-to-date detailed description and categorisation of nebulae, and then to instruct the reader in the best ways to successfully observe and record the large range of astronomical objects that fall under the general heading of "nebulae".
