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 of a couple of years, and feature various combinations of true-color and narrowband data.
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…
Last night I set out to image Jupiter and Saturn, but both are pretty far away at this point, and the atmospheric conditions weren’t great. So I tried for the Moon instead. We take our nearest celestial neighbor for granted – there’s a whole world right next to us, waiting for us to explore it!…
This portion of the Veil Nebula, commonly called the “Witch’s Broom,” is part of a larger shell of gas known as the Cygnus Loop. It’s gases blown off from a supernova that exploded 10,000 to 20,000 years ago! The rich red and blue colors are real; this is not a false color image. Shot over…
A spiral galaxy almost 40 million light-years away, viewed edge-on. The dust lane in the center of its disk, and central bulge are clearly visible. A couple of its smaller, satellite galaxies can also be seen here.
It’s been awhile since I attempted Jupiter and Saturn… years, in fact. But last night was too good to pass up. Jupiter is just past its opposition, and it’s one of its closest approaches to Earth ever. There wasn’t a lot of turbulence in the air late last night, the Great Red Spot was out,…
Here’s IC417, commonly known as the “Spider Nebula.” Just outside of the frame is a smaller one called the “Fly Nebula,” but my field of view isn’t quite big enough to capture them together! It’s about 10,000 light-years away, in the constellation Auriga. Imaged over 15 hours; narrowband nebula blended with RGB stars.
