Good morning, Rallypoint, and welcome to the December 22nd edition of Astronomy Picture of the Day (APOD): "NGC 1365: Majestic Island Universe." First selected as an APOD four years ago (December 2018), the barred spiral galaxy NGC 1365 makes a repeat appearance today to kick off the last Thursday before Christmas 2022. It lies 60 million light years from Earth near the southern constellation Fornax (the Furnace). Total exposure time for this composite image: 36 hours! Some additional photographer notes were available, and here they are:
Telescope: Planewave CDK 17” & 12.5” RCOS
Mount: Software Bisque Paramount ME
Camera: SBIG STXL 11002 with AOX & STL1100M with AOL
Filters: Astrodon
Exposures: HaLRGB

Even a black hole can be beautiful.
Good morning from Goodfellow AFB, Maj William W. 'Bill' Price

Black holes have always been the most captivating thing in all the astronomy shares I've seen.
Something about the way the 'organize' space around them by bringing everything under their gravitational influence into their swirling 'artwork' of space.
Appeals to the human mind's craving for structure, even in an unstructured universe.

COL Randall C. Here's a couple of other pertinent black hole tidbits: X-ray data suggests the center of NGC 1365 has a mass of 2,000,000 solar masses, and that it rotates at near the speed of light. Talk about one big celestial gyroscope.

Maj William W. 'Bill' Price - Absolutely. The numbers are absolutely mind-boggling...
The sun is about 333,000 times the mass of the earth, so that would mean NGC 1365 is about 666 BILLION times the mass of the earth.
According to Universe Today, the Earth has a mass of about 5.9 sextillion tons (5.9x10^21 tons) give or take, so that means the mass of the NGC 1365 is around 4 Decillion tons (4x10^33 tons or 4,000,000,000,000,000,000,000,000,000,000,000 tons)
It's like the US Debt ... when it gets to a certain point it's just too big of a number to grasp.
