A New Image From Webb Shows Galaxy NGC 1365 https://www.universetoday.com/157184/a-new-image-from-webb-shows-galaxy-ngc-1365-known-to-have-an-actively-feeding-supermassive-black-hole/

Image size 2000*1200

Also known as the Great Barred Spiral Galaxy, NGC 1365 is a double-barred spiral galaxy consisting of a long bar and a smaller bar located about 56 million light-years away in the southern constellation Fornax. Measuring over 200,000 light-years in diameter, roughly twice as large as the Milky Way.

Interestingly, the dust bar isn’t nearly as prominent as it is in visible light. In the center is a modest active galactic nucleus (AGN). The circumnuclear dust is also quite striking. This time, I was happy to receive the PHANGS team’s reduction of the data. Makes it much easier because their mosaic was much better matched and aligned.

The image is a mosaic of 690 individual frames taken with the telescope’s Near Infrared Camera (NIRCam) and it covers an area of sky about eight times as large as JWST’s First Deep Field Image released on July 12. And it is absolutely FULL of early galaxies. The scientists, from the Cosmic Evolution Early Release Science Survey (CEERS) collaboration, said the mosaic is from a patch of sky near the handle of the Big Dipper.

My brain struggles to grasp the sheer scale of these images.

I mean it’s a long way to the nearest capital city, but that’s peanuts compared to galactic superclusters.

well that’s kind of how we ended up with models like these

isn’t if

Mine doesn’t.
I know how long a year is, it even seems to pass too fast.
I know how big a billion is, it’s a cube with a thousand on each edge, and I can easily count to a thousand.
So 13.8 billion light years doesn’t seem so far at all.

What these images mean to me is Olbers’ paradox.

If the universe was just a little more dense, then the night sky would be white rather than black. And the heat from the stars would keep me up at night.

Jupiter looks good through the JWST.

Good morning everybody.

Almost clear, almost calm, 16.1°C and 75% RH. BoM forecasts 23°C and a slight chance of rain.

Off to see the doctor at 11 am, to get my annual scan and blood test results. Not much else will be happening.

Sorry about that; it should have been in chat.

Now that’s nice.

IR, so false colour. Coldest parts are white? Or is it hottest?
