Formally Abell 33 or the even more catchy name PK238+34.1, the “diamond ring nebula” is a planetary nebula – that means it’s the gas blown off by a dying star, not too different from our own sun.
This one’s interesting due to its almost perfectly spherical shape, its cyan color from ionized Oxygen gas, and the foreground star that’s in just the right place to look like a diamond on a ring.
We recently obtained a new telescope for observing the planets, and we had our first good conditions for planetary imaging this morning! This is the best image of Jupiter I’ve ever gotten, and I’m hopeful that it will be even better once it gets closer to Earth in a couple of Months. Saturn’s not looking…
This is M17, the “Swan Nebula”. Everyone seems to see something different in it! To me the whole thing looks like a swan seen from the side, but my family sees different birds within it. It’s like seeing shapes in clouds, which makes sense, as this is just a really, really big cloud of gas…
On December 21, 2020, something really special happened in the sky: Jupiter and Saturn had an approach so close that it only happens every 800 years or so. They were so close in the sky that to the unaided eye, they looked like a single, bright star. This led many to proclaim it to be…
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…
Now that our new backyard observatory is up and running, and we’re under darker skies than in our previous home, I’m revisiting some galaxies I’ve imaged before to see how things compare. Galaxies are tough… any amount of light pollution or moonlight really limits your ability to capture faint, wispy details. But the less light…
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…
