Hope to revisit this under better conditions in the future; but this came out OK considering a bright moon was out the night it was taken. The Pinwheel Galaxy (M101) is near the end of the handle of the Big Dipper in the sky, although physically it is tens of millions of light-years more distant.
This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…
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…
It doesn’t take much imagination to see a ghost leaving a trail of ectoplasm in this cloud of Hydrogen gas, lit up by the bright star Navi. To keep with a spooky and ethereal theme, I photographed this object in monochrome using only a Hydrogen-alpha filter.
I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…
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.
If you point your telescope outside of the Milky Way, you’re almost guaranteed to pick up very distant galaxies, because there are just so many of them out there. This patch of sky inside Cancer is a cluster of galaxies called Abell 671. If you click the image and look at it full size, you’ll…
