More fascinating imagery coming from the telescope.

The scale is just mind blowing. I find reading about these findings fascinating yet probably understand about 5% of what it talks about haha. Humbling stuff.

Ha ha, even I wonder how much time it takes to "dumb-down" their technical talk so people like me can marvel at their magic

If ever you want a brilliant read on space stuff, pitched at people like me, try Stephen Hawking "Black Holes and Baby Universes".

Short chapters in plain english, covering a wealth of topics.

And the new photos are truly wonderous, and their explanations even more so

I appreciated the images & the description related to how they can see things in the past i.e they can see the image & calculate the time it takes for the image to reach us - I was always too embarrassed to ask

As always, someone had drawn a cock and balls on it.

I know they use parallax to judge distances to stars....which uses trigonometry for how far a star's position will appear to move when you look at it from different angles...essentially triangles.

[Link]

At a certain distance away the stars just don't move and so they use other techniques for that and I have to admit...while being a complete layman, I regard them as somewhat less certain.

Some kind of measurement of light isn't it? I suppose a few million miles out, or even a couple of billion miles out, are not much at the kind distances being talked about.

For distances where trig doesn't help they use something called a 'standard candle' if I remember correctly.....something to do with a certain type of explosion always being the same strength and so they gauge the distance based upon changed the signal is....something like that.

Never sounded that convincing to me but I'm just an average Joe.

They really should use four candles.

My daughter is a Senior Spacecraft engineer, working on satellites. She was interviewed for the national news, a couple of years ago, as she was in charge of the “net” that was collecting space debris. She laughed afterwards as the interviewer didn’t really understand what she was talking about, so she had to dumb down her answers.
I dread her talking to me about her work as I have no idea what she is talking about, which is a shame as I know it is probably very interesting and insightful

Sorry it was 4 years ago

It's nice when they do well, tips hat.

You should be rightly proud.
