Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner!
Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
Also in Hercules, M92 is often passed over for its larger and more dazzling neighbor, M13. But M92 is pretty in its own way! It’s also one of the oldest globular clusters in our galaxy (over 11 billion years old) and has some very interesting background galaxies around it too.
It’s a good thing galaxies don’t have feelings; they’re just collections of billions of stars. Because NGC 2903 would need therapy. It has no cute nickname like other galaxies; it’s just NGC 2903. And it has no galactic neighbors; most galaxies are gravitationally bound to other galaxies in their local group or cluster, but NGC…
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…
This young star cluster inside the Heart Nebula is lighting up the clouds of gas from which it formed. 3 hours of narrowband exposure from my suburban driveway.
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…
A spiral galaxy almost 40 million light-years away, viewed edge-on. The dust lane in the center of its disk, and central bulge are clearly visible. A couple of its smaller, satellite galaxies can also be seen here.
