Yup. :eek:



Historical note: In my youth, some time between 1960 and 1980, I read a sci fi book with the title Ice World about a visit to Earth by beings from a hot world where lead would be liquid. I have been unable to find a reference to that book online though I did find information on newer writings with that title.

Cooper Flagg and Blue Devil Astronomy

OK, we are all rejoicing in the commitment from Cooper Flagg,.. but

Looking at this very nice announcement/congratulations from Duke Men's Basketball:
https://pbs.twimg.com/media/F9sDhsvbUAA0Dxm?format=jpg&name=small

Can these folks borrow a physicist or take a course?
I'm venturing to say that this Duke Blue Planet, that the blue devil is standing on, doesn't have an atmosphere but has a drone flying nearby. How is that happening without an atmosphere?? Is this our answer to Star War's horses in space? :rolleyes:

Just saying.

In 2020, the OSIRIS Apex spacecraft collected a sample from the Bennu asteroid. It then started a trip to earth to deliver that sample ... today (Sunday 9/24/2023) at 10:42am ET. NASA will be providing a live feed.

Here's a report on the first (public) look into what was returned from OSIRIS:

CNN is running a report this morning too.

Apparently Ice Crystals and Carbon, the stuff of life, has been found in the sample. Good stuff.

Saturn's rings will become un-viewable starting in 2025 and ending in 2032; sounds shady.

Oh the (Saturnian) humanity!

Not quite. The David Copperfield worthy magic trick lasts but a short time, you'll be able to see the rings again in no time. It's in 2032 that we get to see them at their widest point.

This spectacle, however, is but a fleeting cosmic event. As Saturn pursues its 29.5-year orbital dance, it will gradually tilt, once again showcasing the other side of its rings, reaching a peak display in 2032. An upside to this celestial tilt is the enhanced visibility of Saturn's moons.

Eclipse of Betelgeuse

An interesting occurrence will occur tonight (12/11/2023) when our view of Betelgeuse (famous star in Orion) is eclipsed by an Asteroid in our solar system:
https://www.space.com/asteroid-eclipse-betelgeuse-december-2023

The event will start at 8pm EDT according to the article.

Although Orion is nearby (galactically speaking), and is in the same arm of the Milky Way as our solar system, I didn't realize that Betelgeuse is so close to our ecliptic. Although it should have been somewhat obvious; anyone who looks at the night/morning sky will note that Orion is spread over the same 'line in the sky' that we view our planets. Betelgeuse is 'only' 7 degrees off the ecliptic. For comparison, the plane of our moon's orbit is only 5 degrees relative to the ecliptic. FYI, our ecliptic is at a 60 degree angle with the Milky Way's galactic plane.

Adding to this situation is that Betelgeuse has recently been known to have variations in brightness.

Most interesting.

Geminids Starting Tuesday Night

What are you doing after the Duke game tonight?

The Geminids meteor shower starts tonight and peaks on Wednesday night.
Best viewed after midnight; there is a new moon (i.e., no moonshine to create glare :cool:).
