Title: What is this?
Post by: mrt127 on March 27, 2012, 11:06:40 AM
It's near the Sun I have no idea what it is, apparently it has been recently detected, any ideas on what it is?

I think it's Vulpin, A planet that was thought to orbit the sun closer then mercury but was never found.

I think you mean Vulcan, not vulpin.

It looks like a tornado to me. I think those have been reported on the sun before. If you turn the image upside down, you can get a better idea of it

No it wouldn't actually. Not enough force unless it was a gas planet. Assuming it's rocky, it'd happily orbit.

Looks like some magnetic tube that is pushing the plasma away from the region inside it. Can't be the right terminology but that's how I'd describe it.

maybe a comet blew up somewhere and we somehow missed it? :D

I think it's a very thick area of the corona.

Or a magnetic vortex?

Any info on what time that image is and what band and satellite? I could try to get some more data and stuff on it.

Or better yet, a source link please?

Well the density of mercury venus and earth at all around 5.3 . According to wikipedia, it's less

the outer ring is the liquid roche limit which applies to objects that act like a more liquidy. The inner ring is for rigid bodies

I can't quite remember what the gas is called but isn't there large traces of "this Gas", that usually belongs to a gas giant and isn't found on stars, on the sun? This maybe some of the Gas from an inner Gas Giant, that maybe have been slingshot  in.

And I can't find the source, it was something like "Perhaps a new planet."

I found it by using google image source. Couldn't find any actual facts, but all the internets seems to think it's an alien spaceship come to refuel on solar plasma (hydrogen i guess).

Note that objects larger than 60 km have been ruled out. Simply put, modern instruments can detect planets like the hypothetical "Vulcan" around stars hundreds of light-years away. A planet inside Mercury's orbit would stick out like a sore thumb.

There are only two hypothetical planets which are being seriously considered right now; Tyche (believed to orbit at around 15,000 AU) and a possible object at somewhere over 100 AU which could be responsible for the sharp outer edge of the Kuiper belt.

Space.com just posted this up and since you can briefly see that tube structure, I think the pic above is the same phenomenon. The sound effect is obviously added.
