I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope.
But through 2 hours of total exposure time, the colors do emerge, and it is in fact mostly green. It’s brighter now as it’s closer to Earth, but its tail is still underwhelming. But hey, it’s a comet.
It’s been really cloudy lately in Central Florida, so instead of imaging from my driveway, I’ve tried using remote observatories. This particular image was taken using a telescope in Australia, using a service called telescope.live. This is the “Coalsack nebula”, a dark cloud of gas obscuring the Milky Way in the Southern hemisphere. We’re looking…
It doesn’t take much imagination to see a ghost leaving a trail of ectoplasm in this cloud of Hydrogen gas, lit up by the bright star Navi. To keep with a spooky and ethereal theme, I photographed this object in monochrome using only a Hydrogen-alpha filter.
The “Jellyfish Nebula” is a supernova remnant in the constellation Gemini, about 5,000 light-years away. It’s the gas blown off from a star that exploded, sometime between 3,000 and 30,000 years ago – we’re really not sure when it happened. But it makes for quite a spectacle! I was plagued with technical issues while capturing…
Try saying that three times fast! Fortunately, the “Silver Sliver Galaxy” has a formal name that’s easier to pronounce: NGC 891. It’s about 30 million light-years away, and is thought to be very similar to what our own Milky Way galaxy would look like when viewed edge-on. Explore the wider-field image; click on it for…
Last weekend, I hosted an astrophotography workshop on lunar photography for our local astronomy club. Tonight the skies finally cleared, and I got to apply what was learned! Here’s our lunar neighbor, in hi-res glory.
This is the Helix Nebula, sometimes also called the “Eye of God” or the “Eye of Sauron”. It’s a planetary nebula, formed by a star blowing off its outer layers of gas before collapsing into the white dwarf you can see at its center. This is thought to be the ultimate fate of our own…
