Image Description and Details :

In the direction of the constellation of the Puppis there is this pair of open clusters cataloged by Charles Messier as M46 and M47. On closer inspection, in the direction of M46 there is a very small planetary nebula cataloged as NGC 2438, the remnant of a stellar explosion that left a white dwarf at its center. NGC 2438 is 2900 light years away from us and has an extension of "just" 4.5 light years.

Image Description and Details : NGC 7814 is sometimes called the Little Sombrero for its resemblance to the brighter more famous M104, the Sombrero Galaxy. Both Sombrero and Little Sombrero are spiral galaxies seen edge-on, and both have extensive halos and central bulges cut by a thin disk with thinner dust lanes in silhouette. In fact, NGC 7814 is some 40 million light-years away and an estimated 60,000 light-years across. That actually makes the Little Sombrero about the same physical size as its better known namesake, appearing smaller and fainter only because it is farther away. In this view, NGC 7814 is hosting a newly discovered supernova, cataloged as SN 2021rhu, the stellar explosion has been identified as a Type Ia supernova, useful toward calibrating the distance scale of the universe.
