Re: APOD: Jupiter and the Geminid (2023 Dec 28)
Hmmm,,, quick questions - 1) Brightest portion in the middle.. is that where the friction with Earth's atmosphere is the strongest (e.g. left origin up above atmosphere, so not that bright, right ending portion after the max burn falling down from sky) ? Or some other reason ? 2) Why blue-green ligh...

Re: APOD: Betelgeuse Eclipsed (2023 Dec 15)
Thanks to folks posting video/link of occultation. One question remains - why the brightness of star is seen lowering equally (full 360 deg, round) and not partially just where the occultation happened ? Whenever we see moon/Sun getting eclipsed like that - partially, at an angle, cutting it's visua...

Re: APOD: Betelgeuse Eclipsed (2023 Dec 15)
That day I tried to get a "live" video streaming, I looked and searched and searched.. got none. It was disappointing. From the photo (right frame), seems the passing was subtle (not so obvious, not so conspicuous) to naked eyes (or even small binoculars) ? It's strange that people didn't ...

Re: APOD: Andromeda over the Alps (2023 Nov 13)
IF we had a telescope that was powerful enough to see all the way into the Andromeda galaxy, and powerful enough to zoom into a planet that harbored some type of life, would we be seeing images from 2 million years ago or current? From over 2 million years ago. What we "see" is what light...

I've never been fan of such artificial mixture of different compositions with different settings and processing.. What's the purpose ?

Re: APOD: UHZ1: Distant Galaxy and Black Hole (2023 Nov 10)
When the black hole which is supposed to be at the center of galaxy is shown bigger than entire galaxy.. I'm sure it's got to do with different (and digital) zooms of Chandra and JWST just to make it easier for viewers ? It is beyond my capability of understanding how the telescopes and then process...

Re: APOD: Perseus Galaxy Cluster from Euclid (2023 Nov 08)
It's hard not to ask oneself the question, "Why is it dark at night?", when one sees all those little galaxies as crystal-sharp grains of salt richly sprinkled all over Euclid's field. Ann And they say visible material is less than 4% of universe.. I have a hard time even understanding sp...

Still some questions unanswered (from my original 1st post), hoping someone can provide their thoughts if not answers.. 2) Also I wonder how many planets one can expect to form in this disk and 3) What's the width of disk and would it be similar in size (width) so that planets can form at wide dista...

Re: APOD: PDS 70: Disk, Planets, and Moons (2023 Oct 17)
I wonder why planet forming ring is seen brightest, even planet is seen brighter than the actual star? Is it the way the image is taken and processed to show most interesting things blocking/diffusing star's light/brightness ? I'm guessing so. Also I wonder how many planets one can expect to form in...

Huh? It says it's only 50000 ly across.. So not that big. And it says it's one of the large galaxies in Virgo cluster. Really? Not sure and can't imagine if other galaxies in Virgo cluster (or even otherwise) would be smaller than this..

To be honest, didn't find this at all any interesting. Gas (planet) merging into gas (Star). No traces left behind.. What's the big deal ?

Huh? I'm confused. I thought we see such (planetary nebulae) when the star explodes and material is ejected out.. Here, it seems reverse (the material will be sucked in to form a star) ? Oh well..
