The sun is feisty lately.
This solar cycle has been quite a bit more active than forecast. It motivated me to up my game a little bit with solar imaging; this is my first image with a “double stack” setup that results in narrower filtering on the Hydrogen-alpha emissions from the sun. Lots and lots of prominences, filaments, and sunspots…
The Ghost of Cassiopeia
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.
The “Christmas Star?” Not really.
On December 21, 2020, something really special happened in the sky: Jupiter and Saturn had an approach so close that it only happens every 800 years or so. They were so close in the sky that to the unaided eye, they looked like a single, bright star. This led many to proclaim it to be…
The Needle Galaxy
Somewhere between 30 and 50 million light-years away, within the constellation Coma Berenices, lies NGC4565 – commonly known as the “Needle Galaxy”. It’s a spiral galaxy, but viewed edge-on – so we see its central bulge and the edge of the galaxy’s disc extending from it. Clouds of dust within the galaxy obscure the middle…
The Eye of Sauron, revisited
This is the Helix Nebula, sometimes also called the “Eye of God” or the “Eye of Sauron”. It’s a planetary nebula, formed by a star blowing off its outer layers of gas before collapsing into the white dwarf you can see at its center. This is thought to be the ultimate fate of our own…
NGC2903 feels lonely.
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…
