For the other Astronuts out there

They're both 3D surfaces, so it's natural we see them in relief when back lit.

 

Totality cool.

 

Has anyone asked or explained why the shadow isn't a circle ?

Asking for someone else. Definitely not me.

 

Yeah, that and the Moon ain't a perfect circle. Not sure about the gravitational effect. And the shadow is hitting the clouds. And it's also at an angle toward the Northern Hemisphere.

 

The atmosphere causes diffusion as well. "Scattering" is the colloquial term.

 

Scientists using the Dark Energy Spectroscopic Instrument have unveiled the largest 3D map of the universe ever. The results suggest that dark energy, the mysterious force pulling the universe apart, may be weakening, challenging prevailing theories of cosmology.

• Explanation: Baily's beads often appear at the boundaries of the total phase of an eclipse of the Sun. Pearls of sunlight still beaming through gaps in the rugged terrain along the lunar limb silhouette, their appearance is recorded in this dramatic timelapse composite. The series of images follows the Moon's edge from beginning through the end of totality during April 8's solar eclipse from Durango, Mexico. They also capture pinkish prominences of plasma arcing high above the edge of the active Sun. One of the first places in North America visited by the Moon's shadow on April 8, totality in Durango lasted about 3 minutes and 46 seconds.​

Eclipse in Seven​

Explanation: Start at the upper left above and you can follow the progress of April 8's total eclipse of the Sun in seven sharp, separate exposures. The image sequence was recorded with a telescope and camera located within the narrow path of totality as the Moon's shadow swept across Newport, Vermont, USA. At center is a spectacular view of the solar corona. The tenuous outer atmosphere of the Sun is only easily visible to the eye in clear dark skies during the total eclipse phase. Seen from Newport, the total phase for this solar eclipse lasted about 3 minutes and 26 seconds.

How a Total Solar Eclipse Ended​

Explanation: How does a total solar eclipse end? Yes, the Moon moves out from fully blocking the Sun, but in the first few seconds of transition, interesting things appear. The first is called a diamond ring. Light might stream between mountains or through relative lowlands around the Moon's edge, as seen from your location, making this sudden first light, when combined with the corona that surrounds the Moon, look like a diamond ring. Within seconds other light streams appear that are called, collectively, Bailey's beads. In the featured video, it may seem that the pink triangular prominence on the Sun is somehow related to where the Sun begins to reappear, but it is not. Observers from other locations saw Bailey's beads emerge from different places around the Moon, away from the iconic triangular solar prominence visible to all. The video was captured with specialized equipment from New Boston, Texas, USA on April 8, 2024.

These Dudes are expected to make an appearance in Illinois soon. We call them Cicadas.

 

St. Louis gets their share.
