Is there an explanation for the formation of this mesh-like structure, which becomes visible in the IR?
Maybe since you now get to see to the inner cores of dense material, your looking at the condensed bars that are driving the formation of all visible material in the galaxy?

Re: APOD: Messier 10 and Comet (2022 Jul 21)

Have stereo viewing images been made before of a comet in two adjacent positions in time? I wonder what could look like.

Re: APOD: Ingenuity: First Flight over Mars (2021 Apr 20)

The engineers that put this together are awesome.

I noticed what I think is a video aliasing effect of the two rotors seemingly synchronized to the shutter, makes it look like each blade is stationary on either the left or right.

Re: APOD: Fifty Gravitational Wave Events... (2020 Nov 04)

Interesting, I like the chandelier effect. Seems to show the increased likelihood of higher masses merging than lower, but also that similar masses seem to be more likely to merge. Maybe it's because it's easier to detect similar or higher mass mergers. The last think I noticed is that most mergers ...

Wow, great way to put scale into tangible perspective, about 100 years to get there driving 100 mi/hr.

Re: APOD: Saturn's Northern Hexagon (2020 Jul 05)

The interesting difference between the lab experiments of the hexagon effect and Saturn's is the lab seems to show eddies that seem to hold in the sides of the hexagon, forming it. I don't notice them on the planet images so far https://en.wikipedia.org/wiki/Saturn%27s_hexagon#/media/File:PIA21611_-...

The coordination with Parker might make for some really interesting 3-D images/movies of flares, or views into those "magnetic windows" previously mentioned here: https://apod.nasa.gov/apod/ap200203.html

It was. Function is way more important than form at this point in our exploration of Mars.
Here's how an architect would get to Mars

Wondering if the speckled coma appearance is an artifact of the imager itself, or actually comes from particles.

Re: APOD: First Horizon-Scale Image of a Black... (2019 Apr 11)

It’s claimed the telescope array has enough resolution to resolve writing on a coin at the distance between New York and Los Angeles. That’s crazy. I wonder how they collimated such a device. Awesome work. They will have a career in resolving other objects out there.
