I wonder how today's grid would handle a direct hit from a Carrington Event or stronger CME. How long would the power stay off?
I'm not sure but it would be good to have one of these to help our infrastructure.
It was determined only this century that zodiacal dust was mostly expelled by comets that have passed near Jupiter. What about the Mars origin theory supported by Juno data? Indeed, the evidence now heavily favors that explanation for the creation of the majority of the interplanetary dust responsi...
If a large star could become a neutron star, then a neutron star could become a black hole, what could a black hole become? Say something 3D is changed into a 2D object, what would be its 1D counterpart? I guess I might as well ask what a 4D cat ball looks like. Quasars are like that; let alone a mi...

Begs the question why some APOD's aren't presented in a fully resolved format. :? "Fully resolved format"? They're scaled for the main page, which links to whatever maximum size the imager provided. I often forget to "click" on the image to see it in full resolution. Okay… who l...
The entire sky. Been playing around with the new allsky camera I've been developing. Here's a single capture- you can see Orion, the Pleiades, Cassiopeia, the Big Dipper, and more. And a stack of 2100 images covering about 12 hours, twilight to twilight. Fun. _ M20220204_211619.jpg 2022.02.04 Stack...
As the grand structure of the universe goes, what would be the order of things? Cosmic background radiation>filaments and voids>super clusters>clusters>local group>Milky Way>solar system. It’s hard to organize these in my mind at the scale they are represented. And what’s a cluster wall ? :bang: Yo...

Doesn’t redshift have some inherent flaws ? It may be the best tool in the box but all devices usually have some practical limitations. Using just wave lengths can be tricky . :wink: Interesting things to contemplate. (Also: http://asterisk.apod.com/viewtopic.php?f=31&t=42158) However, I was si...
