Are Sunspots Caused By Comet , Asteroid, and/or Meteor Strikes?
It's openly admitted that the origin of sunspots is unknown and a mystery. So, is it possible they are caused by the large objects hitting the sun?

And, taking it a step further, couldn't they also be responsible for solar flares in some cases?

No and No.

Sunspots are surface manifestations of deeper workings within the sun. Some are really huge (Jupiter sized) and a comet or other space material just wouldn't have enough mass to affect the Sun in any way that would be visible from Earth

KY6, I think your wrong.

How do you explain this Quicktime video...

From your own link (dated June 4, 1998)


"The sun, in an apparently unrelated event after the collision on Tuesday, spewed out a mass of solar gas from its interior, the scientists said. The gas eruption is called a Coronal Mass Ejection.

Re: Are Sunspots Caused By Comet , Asteroid, and/or Meteor Strikes?
KY6, it's very convenient to state that it's "an apparently unrelated event." And, scientists know this how? Because they have a firm grasp of the sun's workings?It's apparently unrelated because it goes against current solar mechanics orthodoxy. Anyone with eyes and a brain can make the connection that two comets hit the sun and triggered two CME events and are related in some way. It's simple logic based on observations and facts derived from the video evidence. There's plenty of other video evidence which shows the same cause and effect from comet strikes on the sun and sunsequent CMEs.

Postman, if you look hard enough there is plenty of video evidence from SOHO showing causality. I do not have the time to gather the info, but rest assured it is there.

Re: Are Sunspots Caused By Comet , Asteroid, and/or Meteor Strikes?
KY6, taken from your link. Sunspots are depressions on the sun's surface. Hmmm...I wonder where a depression would come from. scratching

"Physics

A sunspot viewed close-up in ultraviolet light, taken by the TRACE spacecraft.Although the details of sunspot generation are still somewhat a matter of research, it is quite clear that sunspots are the visible counterparts of magnetic flux tubes in the convective zone of the sun that get "wound up" by differential rotation. If the stress on the flux tubes reaches a certain limit, they curl up quite like a rubber band and puncture the sun's surface. At the puncture points convection is inhibited, the energy flux from the sun's interior decreases, and with it the surface temperature.

The Wilson effect tells us that sunspots are actually depressions on the sun's surface. This model is supported by observations using the Zeeman effect that show that prototypical sunspots come in pairs with opposite magnetic polarity. From cycle to cycle, the polarities of leading and trailing (with respect to the solar rotation) sunspots change from north/south to south/north and back. Sunspots usually appear in groups."

Postman, I can't prove anything when even the experts that you claim to put your faith in don't know the answer themselves.

Re: Are Sunspots Caused By Comet , Asteroid, and/or Meteor Strikes?
And, btw...I'm just curious. What would be the harm if comets actually are the cause of solar flares and sunspots anyways?? Why is there always this intellectual resistance to any theory that runs counter to prevailing thought? Isn't scientific knowledge about the continual search for scientific truth wherever that leads?

Sunspots follow a well-established 11 year cycle in number and location (latitude-wise) on the Sun. It is unlikely that comet strikes would be able to explain that pattern.

16007, what if the Sun encounters "meteor showers" approx. every 11 years much like the Earth does every year at various times? After all the sun is revolving too around the galactic core.

And, I agree that there is a stronger case to be made that CMEs could be caused by comet strikes rather than sunspots, but I'm not ruling out the latter.

Postman, what if it has been hasn't been reported as such. For some reason any tenets embraced by the scientific community as a whole are vigorously defended even if disproved by valid scientific discovery. Now why is that? Hint: $$$

If you had thought that through you would
know that that is a silly idea.

If science were wedded to the status quo
and had means to enforce it, there would be
NO progress.

In real life however tens of thousands of
new discoveries are reported each year.
Doing original research, however mundane, is
necessary to earn a Ph.D. and to getting noticed.
It's where the money is.

However, if you come up with a new idea that
conflicts with existing knowledge, people
are not going to take it for granted.

Re: Are Sunspots Caused By Comet , Asteroid, and/or Meteor Strikes?
me thinks electromagnetic forces are at play. Maybe attractions with distant and powerful objects or even the interaction of plasma between the celestial bodies of our solar system.

Maybe the galactic arm or core has some small connection in this orchestra too.

Comets too small and infrequent to account for the numerous sunspots that appear.

Watch late 2006 into 2008 and you may learn more as we all will.

I think scientists understand the Sun well
enough not to have much need for speculation.
Did you know that they can 'see' the other
side of the Sun?

Looks to me like the link to quick time video only shows a solar flare, not a sunspot.

Yes, it does appear, in that 2001 video, that the sunflare was caused by the object colliding with the sun back then. It has nothing to do with sunspots.
