Do you like Earth's solid surface and life-inclined climate? Thank your lucky (massive) star

Our friendly super nova should still be around in some form, shouldn’t it?

How about we Thank God “prof”?
Or is that too backwards for you?

Psalm 19:1
For the director of music. A psalm of David. The heavens declare the glory of God; the skies proclaim the work of his hands.

I watched this on The Science Channel the other night.

We’re all made of Nebulas.

Except for Joy Behar.

She’s made of crap.

[blueunicorn6]

There was all these explosions and things expanding and shrinking.

It reminded me of my honeymoon.

Interesting, at one time about 650 Million years ago the earth was covered with ice (one of thousands of Ice ages) and the only thing that kept life going was the vents under the ocean which kept enough heat to survive. Then as the sun went through one of its heating cycles the warming period came.

BTW, we are about 1,000 years past the average warming cycle so get ready.

[sparklite2]

I see a brown out there, but those a sub-stellar. What does your illustration say about the pre-cursor star that formed our elements?

[sparklite2]

Yeah, and we’re clamoring to stop the warming that may be forestalling the next Ice Age. It’s amazing creatures so stupid have lasted so long.

[Reily]

Technically we are still in the Quaternary - a period of cyclic transcontinental glaciation. We are in a warming lull. (Even to those in Rio Linda “cyclic” means reoccurring!) But you are right if there is AGW it might be delaying that “mile-of-ice-over-Manhattan” thing!

Recently found this nugget...

I wouldn’t say the Sun is dying but a long term cooling trend is highly likely!

Wish upon a star ping.

[sparklite2]

Whatever happened to global dimming?
We could pump the atmosphere full of
aerosols and cool off!

[stubernx98]

So true. One of the things we could do to stave off the ice age is to put huge vinyl reflectors into orbit that would increase reflection by about 20%. As the moon moves closer to earth the internal core will heat up and there would be a source of heat.
Or we could move to Venus.

[Openurmind]

I think he should not have used that word because the article explains a Solar "cycle". I think he is saying it is ready to temporarily die for an extended term. And as we know it is, it's late. The last one was about 120k ago and lasted for approximately 100k.

[Openurmind]

I think the interesting thing he brings up is the decrease in “solar-wind pressure” aside from the decrease in solar radiant energy.

Dug deeper and found this about solar winds. http://www.iceagetheatre.ca/transcripts1/ttda005.htm
