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...

Re: APOD: PDS 70: Disk, Planets, and Moons (2023 Oct 17)
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...

Re: APOD: The Sombrero Galaxy in Infrared (2023 Aug 13)
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..

Wow.. never imagined there's so many with their paths around Sun that close (relatively) to each other and all planets. We have decent idea about none of the PHA's (ones we have discovered/identified so far) colliding with Earth in next 100 years, I wonder, what's the probability of them hitting oth...

Re: APOD: Pandora's Cluster of Galaxies (2023 Jun 09)
Very interesting and intriguing. I wonder - 1) how come this region seems to have sooooooooooooooooooooooo many "red shifted" (super old) galaxies behind the foreground galaxy cluster and what's their age (how old are they). Normally in other gravitational lensing photos, we tend to see lo...

When the Sun gets nova, our Earth will be eaten and that will happen in 3937 as prophesized by Nostradamus as the end of the world. This can be scientifically proven by Arthur Clarke's novel The Songs of Distant Earth. Lol.. Whole world was going to come to an end on 21st Dec 2012.. And we are here...

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 ? Nothing spectacular, no dent.. like mixing river water into ocean.. Also not sure why in 8B years earth will fall into Sun, I thought the Sun was expected to die...
