The Whirlpool Galaxy

Located about 2,400 light-years away in the constellation Cepheus, the “Elephant’s Trunk Nebula” has a distinct “Pillars of Creation” vibe when viewed as a long-exposure, narrowband image in the style of Hubble. Like the “Pillars of Creation” (the Eagle Nebula,) the Elephant’s Trunk is also an area of star formation, containing some young, newly-formed stars….

This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…

It’s globular cluster season, so here’s another one! M80 is found within the constellation Scorpius, and lies a distant 32,600 light-years away – making it one the small side from our vantage point. It contains several hundred thousand stars, and is one of the denser globular clusters in our galaxy. The faint galaxy in the…

Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it…

M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.

The Horsehead and Flame nebulas, although popular, are really difficult to image together. The clouds of Hydrogen look best using narrowband filters, but the blue reflection nebula below the Horsehead only appears in wideband, color filters. Further complicating matters is the bright star Alnitak, one of the stars that makes up Orion’s belt. In narrowband,…
