The Sun and Comet Lemmon Duke It Out in Sky Candy

In the meantime, it's been a great week for comets...

Here's a timelapse of about 40 minutes of movement. You can see not only the movement against the stars, but the way the tail streams away from the nucleus. This is monochrome due to the way I had to cycle through filters to capture color.

I'm shooting it again tonight. WOW. pic.twitter.com/xrtPtRC5S4

... and aurorae.

Oh, and photobombing meteors.

From Mount Everest too.

The Sun is not taking this lying down.

Comet Lemmon replies.

Hello Everyone, Comet LEMMMON has been putting on an amazing show, and this is the wildest I have seen the tail. I captured this last night. I used my Celestron RASA telescope, ZWO ASI533MC color camera, and an Antlia L-Filter. pic.twitter.com/5fi4HcL26Y

But there's been other stuff too. (I believe if you click through, Grok will translate the Japanese.)

I suppose I'm sort of reaching for this one.

Orion has so many great views.

There have been a lot of pictures of star-forming stellar nurseries recently.

The Grok algorithm has figured out I like astrophotography, and is giving me some great stuff.

We really don't have enough time to really see what's happening.

Good morning! Most stars have planets—exoplanet discovery's revolution. Here, baby stars form in NGC 2071 (top) and Messier 78 (middle), 1,600 light-years away, amid dust. They'll rule planetary systems! Have a wonderful day!

I would like to collect images of the whole life-cycle of a star — not the same star, obviously. This is where the Sun is heading, eventually.

And this is where they come from. The blue parts are all new stars being formed.

It wouldn't be sky candy without a shot of the Seven Sisters.

Now, this one is just fascinating. I'm sure most of you all know about the mysterious phenomenon called "dark matter" — the way that on a large scale, it appears that there is more mass than can be accounted for by what can be seen. It's easy to think "dark matter" is a thing, but we really don't know that. In this case, "dark" means just "it seems to be there but we can't see it."

Well, in these images, we still can't see it, but we can see how it's affecting starlight passing through it. 

Dark Matter's Secret Glow: It Might Not Be Invisible After All! For decades, scientists have insisted that darkmatter—the enigmatic force comprising 85% of the universe's matter—is completely invisible, refusing to mingle with light. But hold onto your telescopes: a… pic.twitter.com/VyI8eBIkmC

So, let's finish out the day with another comet in a wonderful composition.

And that finishes it out for today. Sorry it's so late, but there was some great stuff over the weekend so I hope you'll forgive me. As always, I love comments, and I promise next Friday's sky candy will come on Friday.

Which is Halloween. 

Hmmm.
