Good afternoon, Rallypoint, and welcome to this edition of Astronomy Picture of the Day (APOD) for February 6, 2025.
American astronomer Edwin Foster Coddington first noted 'a large, faint nebula' on some exposures taken prior to April 20, 1898, and confirmed his discovery two days later with his colleague William Hussey. Named after its founder, IC 2574 shows clear evidence of intense star forming activity in its telltale reddish regions of glowing hydrogen gas. This is from the astrophotographers' website courtesy of Google Translate:
"The Coddington Nebula is a dwarf spiral galaxy located 12 million light-years from our Solar System. Its diameter is 47,965 light-years, and it is moving away from us at a speed of 57 km/s. It is assumed that 90% of its mass is dark matter. IC 2574 shows no signs of interaction with other galaxies. It is actively forming stars: based on UV analysis, star formation clusters 85-500 light-years across can be detected in it."

To me....this view (many others too) is awe inspiring and a privilege, and any testable information and knowledge that we can gain from it is a bonus....this IS WORTH having my tax dollars spent on. In fact I pretty much expect it Hydrogen RULES....but that's just my opinion...
