Re: APOD: The Cigar Galaxy from Hubble and Webb (2024 Apr 15)
There is, in the upper right part of the Webb image, something that looks like a globular cluster and which is completely invisible in the Hubble image. Impressive. Alex Interesting… not even the enlarged Hubble image is sharp or detailed enough for me to notice any individual clusters, especially ...

Re: APOD: Detailed View of a Solar Eclipse Corona (2024 Apr 02)
Given that the sun is about 1.4 million Kilometer (865 m Mi) in diameter, they appear to be at least 1.5 mK long, depending on what is considered the edge of the ‘petals’.SpaceCadet wrote: ↑Tue Apr 02, 2024 8:38 am How far out do the petals of the corona extend? They seem huge.

So we have the Spaghetti Nebula, surrounding a neutron star that in its interior has a spaghetti phase of exotic matter, along other edible phases like gnocchi, lasagna and Swiss cheese. Tasty environment!

Re: APOD: Along the Taurus Molecular Cloud (2023 Nov 23)
For a numbskull person like me, those instructions were not too clear. Ann Indeed, I was looking for the T Tauri star, thinking it was the bright one at top center. But that didn’t seem to make much sense. Had to look very closely at the full image to find the actual T Tauri. Thanks for your clarif...

Re: APOD: M15: Dense Globular Star Cluster (2023 Jun 15)
There are maybe 10 stars within 10 lightyears from Earth. Imagine it being 50,000! The night sky would never be black, but instead have a ‘milky’ glow, perhaps even perpetual daylight, and be absolutely covered with stars that could shine as bright as a full moon.

Re: APOD: InSight's Final Selfie (2022 Nov 04)
Would brushes to sweep the stuff away be so much extra load? Good to get twice the design life, but what if the sand had come and terminated the mission after a month? Never understood that myself. Adding a rudimentary brush system might extend the designed lifespan, maybe even double it. But I’m n...

Re: APOD: Jupiter and Ring in Infrared from Webb (2022 Jul 20)
That the Great Red Spot is hotter than anything else on Jupiter might be expected - it's a welling up from deeper layers. But why are the Poles hotter? John I’m just guessing, but maybe Jupiter’s much stronger magnetic fields create more friction between particles near the poles, and thus more heat?

Re: APOD: Tycho and Clavius at Dawn (2022 Jul 16)
WHy is the Moon so cratered and the Earth isn't? Several reasons: First, the Earth has an atmosphere that helps burn up most of the smaller meteors (shooting stars). Second, the Earth is geologically active. Continents move and shift, volcanoes form new land and cover existing land with lava. Third...

Re: APOD: Game: Super Planet Crash (2022 Jun 19)
Made it to a 1000 easily after a few times, with scores up to a couple of million. But they don’t get saved. Put a brown dwarf really close to the star and create a binairy pair. Ghe add a few extra on the outer edge and speed it up to max.

Re: APOD: Quadruple Lunar Halo Over Winter Road (2022 Jan 02)
I really don’t see the distinction between the 4 phenomena either, aside from the 22 and 46 degree rings. The explanation seems to be pointing at different parts of the same circles and giving them different names. Also the streaks on the right of the 22 degree circle might just be thin clouds.
