Re: APOD: JWST on the Road to L2 (2021 Dec 31)
Would it be fair or correct to describe Webb as the most sensitive thermometer ever launched? Designed to observe in IR by collecting photons emitted of a thermal origin, it makes me think of it as a temperature measuring device. Albeit one that might be able to block out a hot sun to see where ET ...

Re: Weather- volcanoes- earthquakes
Why did ancient people build pyramids? To me they resemble stratovolcanoes. Egyptians and Mayans favored a volcano-like structure perhaps because of the angle of repose but why did they think pyramids would immortalize their leaders?

Re: APOD: Solstice Sun and Milky Way (2021 Dec 21)
Today's APOD reminded me of a recent post. I was curious if we were high enough above the plane to notice the broad disc – minus the dust clouds?
After time to pause, I’m pretty sure I’m not high enough to notice.
But that sun sure is bright! ![Yes. :yes:](./images/smilies/yes.gif)

"Of all the gin joints in all the towns in all the world, she walks into mine" is about right for interacting galaxies. But you might expect more double-nucleus barred spirals would be reported. ![Confused :?](./images/smilies/icon_confused.gif)

Let’s say a nearby star is going supernova today. Predicting that has some scientific evidence .

Perhaps what happened to Comet Holmes may happen to Comet Leonard. If so, we should celebrate with a frozen and fried desert.
They will be keeping an eye on it.
It would be a Merry Christmas!
