Astronomy Picture of the Day -- Comet ISON from STEREO
NASA ^ | November 23, 2013 | (see photo credit)

Posted on 11/23/2013 9:37:38 AM PST by SunkenCiv

Explanation: Still intact, on November 21 Comet ISON (C/2012 S1) swept into this animated field of view (left) from the HI-1 camera on the STEREO-A spacecraft. The camera has also captured periodic Comet Encke, Mercury, and Earth, with the Sun cropped out of the frame at the right, the source of the billowing solar wind. From STEREO's perspective in interplanetary space, planet Earth is actually the most distant of the group, seen in its orbit beyond the Sun. Mercury is closest, but both planets are still so bright they create sharp vertical lines in the camera's detector. Both comets clearly sport substantial tails, but ISON is closer to the camera and will continue to move more rapidly through the field. Cameras on STEREO and SOHO spacecraft will be able to follow Comet ISON as it falls towards its close encounter with the Sun on November 28, even as ISON gets more difficult to see in the bright dawn skies of planet Earth.

Looks a bit like fertilization to me.

Cool image. You see the effects of the solar winds.

We must have seen the same “fertilization movies” when we were in middle school. LOL! That’s what it looked like to me as well.

Also, the movment of Encke’s tail is very interesting. I never thought of a comet’s tail having that kind of motion.

Went out this morning to Ft. Pulaski to try to catch something, ANYTHING.

I did see Comet Lovejoy. It’s almost overhead at 5:00am and approaching the tail of the dipper.

I saw Mercury and Saturn rise (along with skyglow), but, I was fighting a band of clouds and said skyglow, so I may have not or I may have seen the nucleus of ISON.

Too Much glow now, have to wait til it gets brighter or further away from the Sun.

BTW, when I got home this morning, the band of clouds had parted and I got a nice view of Mercury before Sunrise.

I am assuming that the sun is to the left, which would mean that the tails are pointing in the wrong direction. A comet’s tail always points away from the sun no matter what direction it is traveling.

Sun to the right. The moving material from the right is from the Sun.

Not sure about the angle here though. In the Sky, ISON is passed Mercury, but, I don’t know if it has crossed Mercury’s orbit....Sky Safari makes it look like it has, but...

So, is this thing finally visible to the naked eye?

Good question, I dunno. I think that will happen in December.

When there’s no overcast, Jupiter is the big one in the sky here. No scope though, and I can’t hold binoculars still enough.

Sun is to the right, why is Earth inside Mercury’s orbit? Or what am I missing here?

I hope it doesn’t fertilize Earth, or we’re in big trouble.

Yeah, this is disorienting. The position of the satellite makes this possible — Mercury is much closer, Earth is much bigger.
