This comet will reach its brightest point a couple of weeks from now, but the skies were clear this morning so I figured I should go for it while I can! The tail’s not as pronounced as I hoped, and processing is a bit sloppy in a couple of spots. But hey, it’s a comet. Pretty.
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…
This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…
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…
The galaxy M106 is an interesting one; it’s large and relatively bright – about the same size as Andromeda. And it’s in a busy part of the sky, within Canes Venatici, with lots of galactic neighbors. This image has been enhanced with Hydrogen emission data; that’s what the red dots and tendrils are. There’s one…
An interesting emission nebula 30 light years across. Imaged with narrowband filters.
It’s a good thing galaxies don’t have feelings; they’re just collections of billions of stars. Because NGC 2903 would need therapy. It has no cute nickname like other galaxies; it’s just NGC 2903. And it has no galactic neighbors; most galaxies are gravitationally bound to other galaxies in their local group or cluster, but NGC…
