One of the largest and oldest (13 billion years) globular cluster of stars near our galaxy – there are hundreds of thousands of stars in there. There are some interesting theories that globular clusters such as this are what remains of smaller galaxies that our Milky Way has consumed – this is just what’s left of the galaxy’s core.
A lot of things have to come together for a good image of the planets. The air needs to be as still as possible, the planet you’re imaging needs to be as directly overhead as possible, and the planet itself should be as close to the Earth as possible. And then, all your equipment has…
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…
Yeah, it’s been a couple of months since we’ve done a live star party online, or posted any new pictures. That’s just summertime in Central Florida for you – it’s been too cloudy to do any imaging or observing. The skies should start clearing up more in a couple of months, and we have every…
Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it…
Jupiter and Saturn both reached “opposition” over the summer, meaning they had their closest approach to Earth for the year. Florida’s summer weather conspired against photographing the planets at that time, but the skies finally cleared last night. They’re not at their closest, but… they’re close enough. I think this is my best Jupiter image…
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…
