A Spooky Knot in the Veil Nebula

Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…

The larger galaxy in this image goes only by the boring name “M106”, but it’s anything but boring. About 23 million light-years away, M106 is pretty similar to Andromeda in its size and brightness. But M106 is a lot weirder. In addition to its slightly warped shape, M106 is the home of a giant water-vapor…

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.

The Horsehead and Flame nebulas, although popular, are really difficult to image together. The clouds of Hydrogen look best using narrowband filters, but the blue reflection nebula below the Horsehead only appears in wideband, color filters. Further complicating matters is the bright star Alnitak, one of the stars that makes up Orion’s belt. In narrowband,…

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…

Formally IC1396, this cloud of interstellar gas and dust is thought to be an active site of new star formation. And with a little imagination, it kind of looks like an elephant’s trunk. There’s more to it than you see here, but I tried to get an interesting framing. From this angle we see a…
