The Sunflower Galaxy

M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…

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…

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 dim nebula in the constellation Perseus has no name, apart from its catalog numbers NGC 1491 and LBN 704. I think it deserves one. It reminds me of the Bubble nebula – if you look closely, you’ll see a “bubble” at center being created from the stellar wind of the hot star that is…

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…

Last night marked Jupiter’s “opposition” – this is the time of year where Jupiter is at its closest point to Earth, and it’s at its biggest and brightest. By a stroke of luck, we had unusually clear skies for this event, and its moon Io was also crossing in front of Jupiter! You can see…
