There are a lot of stars in this picture; the gases of the Wizard Nebula (formally SH2-142) are the birthplace of those stars, and more are being created even now. It’s located about 7,200 light-years away, and is extremely dim – it took over 9 hours of exposure time to capture this image. Your ability to see the shape of a medieval sorcerer is a test of your imagination!
This is a bright, popular nebula deep within the summer Milky Way… but it’s low in the sky, and this is the first time I’ve been able to capture it above the trees. Still, short summer nights and cloudy summer weather present its challenges. Shown processed in the “Hubble palette” and an approximation of its…
This is NGC281, or the “Pac-Man” nebula. I think it’s one of those objects that might look a little like its name if you’re viewing it through a big telescope in a dark sky, but takes on a totally different character in long-exposure, narrowband images such as this. This is a total of 13 hours…
Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…
This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…
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…
There’s a comet in the sky! They don’t appear this bright very often, so don’t miss what could be a once-in-a-lifetime chance to see a comet with your own eyes. It’s tough to spot here in suburbia with your eyes, but it’s easy to see with binoculars. Its official name is C/2020 F3 NEOWISE. Just…
