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.
Last night was hazy, cloudy, and with an almost-full moon that would wash out anything else I could try to image. So, I imaged the Moon itself. Tried out some new techniques; usually you would use a specialized telescope with a specialized camera and specialized software for shooting the Moon, but I wanted to see…
Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…
Located 63 million light-years away in the constellation Coma Berenices, M91 is part of the Virgo cluster of galaxies – and if you zoom in and explore this image, you’ll find many other galaxies surrounding it, and also far in the distance beyond it.
The “Flaming Skull Nebula” (SH2-68) is an old, dim planetary nebula that’s about 40,000 years old. What makes it unique is its structure; it is the fastest-moving planetary nebula measured, and as it moves through the intersteller medium, its gases are getting mixed into the galaxy – leaving a trail behind. Not to brag, but…
The Cocoon Nebula in Cygnus is a compact cloud of Hydrogen, lit up by the bright star in its center. Dust lanes can also be seen across it, obscuring the ionized Hydrogen gas behind them. This object is best imaged during the heart of Summer, which means really challenging conditions here in Florida. High humidity,…
This rarely imaged… thing… is the mess left behind by the hottest star in our galaxy: WR-102, one of only four known Oxygen-sequence Wolf-Rayet stars in the Milky Way. It’s already burning Helium – maybe even past that point – and is about to go supernova. It’s located within the rich starfield of Sagittarius, looking…
