Fascinating videos worth watching. A+

When I was a kid I used to image our glass topped patio table was the Milky Way galaxy and the table top was made of grains of sand and one grain of sand was a star in the galaxy.

Then, I imagined that each person in the world had a similar patio table at their house around the world, representing each of the other galaxies in the universe. At the time, there was about 3 billion people in the world so my wild imagination would have estimated 3 billion galaxies, one for each person in my attempt to fathom it all. So even if I was right, if one grain of sand on each of these 3 billion tables is a star, that's a huge amount of stars, I thought at the time. When my kids were growing up, I used to tell them about how I looked at the size of the universe, as silly as my model was.

Now we learn (true or not) that they think there are 2 trillion galaxies, not the 3 billion I'd predicted as a kid. So, my guess too small by over 600 fold.

Sorry for the rambling. I'll go to bed now and thank my lucky stars that I'm still here and still able to remember when I was a kid! Good night!

Somewhere (can't find it now) was a recent image of Venus, dubbed something along the lines of the clearest ever taken. Not what I was expecting at all, based on all the previous images I have gathered in my head of said celestial body.

The image I saw was different. Can't even remember where I saw it now.

Wait, am I in the old thread again???

We can detect exoplanets with James Webb space telescope.
We can analyze their atmosphere to determine the possibility of inhabitants.

If somebody out there exists and is smarter than us, they know we are here.

1. More advanced civilizations have become extinct.
2. They are watching us, but don’t want to contact.
3. Contact is not possible due to different kind of life forms.
Any other plausible explanations?

I read the fractal geometry paper from the researchers in Toronto as it relates to medicine and the early detection of cancer. Truly amazing. A+++

They had a show (Netflix?) about the JWST. Simply AMAZING work of human craftsmanship. Also quite interesting to see the post-processing that goes into making that image. JWST didn't "see" it that way initially, since it's not looking in the visible spectrum.

I still struggle to wrap my head around the idea that image is x million years ago, but the light is just getting to us.

It takes Pluto 248.09 Earth years to complete one orbit around the sun. Plug that information into a timeanddate.com calculator along with its discovery date, and you'd find that Pluto will complete its first full orbit since its discovery on Monday, March 23, 2178.

[UncleWede]

Wait, is Pluto back to being a planet now??

That picture of Whirlpool is from how many millions of years ago??????

If we became a country on July 4, 1776, then on July 26th this year Pluto will have completed it's first orbit. Ponder that.

And the length of it's orbit is over 23.2 Billion miles. It travels 94M miles per year. Or, 10,800 mph.

By contrast, the earth travels about 67,000 mph.
