Webb Telescope Captures Supernova Appearing Three Times Due to Spacetime Bending

A gravitational lens tripled the event in the night sky and helped astronomers measure the rate at which the universe is expanding.

Thanks for sharing these updates, Tom. This stuff underlines how inconsequential we are in the grand scheme of the universe. Here is distant light distorted by a cluster of galaxies (!) 3.6 billion light years away. The light source is likely an order of magnitude more distant than that.

Then the article references a 13 billion (with a B!) year old star spotted in a similar manner. There's no escaping that we are in the midst of learning more about the origins and inner workings of the universe and physics than all learned in human history so far.

And the sheer math involved underlines that there simply must be other forms of intelligent life out in this vastness. Or at least that have existed over different times through the course of 13 billion years.

I can't even comprehend what football discussion boards are like in other universes. I wonder if they're posting about us!

Given that the observable universe is 46 billion light years in any direction from Earth, most of those other civilizations evolved through sports like football billions of years ago. That assumes they were able to avoid killing themselves.

Fortunately the light from their Plotit days is just now reaching us.

'Ridiculously smooth': James Webb telescope spies unusual pancake-like disk around nearby star Vega — and scientists can't explain it

The nearby bright star Vega is surrounded by a surprisingly smooth, 100 billion-mile-wide disk of cosmic dust, confirming that it is not surrounded by any exoplanets, JWST images reveal. And scientists cannot explain its lack of alien worlds.

It's fascinating that, despite how it's taught in academia, we still don't know much about the big bang, or if it actually happened. An actual detailed explanation of gravity still eludes us.

James Webb Space Telescope smashes its own record to find the earliest galaxies that ever existed

The James Webb Space Telescope has spotted five galaxy candidates dating to just 200 million years after the Big Bang, making them the earliest ever detected. And there could be many more.

A nearly inconceivable achievement.

I’m currently reading “The First Three Minutes,” by Steven Weinberg, Nobel Prize for Physics 1979, and his description of the sheer brilliance of astrophysicists is really something.

Yes, it’s the first three minutes after the Big Bang.

It’s a good book but Simon Singh’s “The Big Bang” is the one you want.

"the light you're seeing from the red objects below is generated by the black holes at the center of these early galaxies."
Can somebody please explain black holes to me? I thought that they we so massive that their gravitational pull would not allow light to escape. The above statement from the article seems to contradict that.

Material spinning around the black hole at dramatic speeds - but not dropping in as it doesn’t cross the event horizon -generates the light.

The James Webb Space Telescope has taken its first look at the near-Earth asteroid 2024 YR4 before a perilous close approach in 2032. The telescope confirmed Earth is safe, but there is a 3.8% chance that our moon may be in trouble.

As these earlier galaxies get discovered, it adds further questions into our theory for how the universe formed.

The math is shaky on a fully formed galaxy just 280 million years after the Big Bang. Something has to give here.

I am in the camp that Webb will force us to blow up many of our long-held assumptions about the universe. That’s good.
