APOD: 2021 August 18 - Rings Around the Ring Nebula

787

Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Rings Around the Ring Nebula." Yesterday's Hubble image of the Ring Nebula (M57) was nice, but take a look at this collaboration between the Hubble, Large Binocular, and Subaru Space Telescopes. You are looking at color-enhanced radiation wavelengths of 469 nm, 502 nm, 656 nm, 658 nm, and 2.1 microns.

The three imagery datasets show visible, infrared, and red light (from hydrogen) in a single composite image, extending much further from the central star than we saw previously. It's always amazing to me what you can find...if you just look.

Our friend SP5 Mark Kuzinski would probably be posting this now if he could. So I will.

Adam Again – “River on Fire”

The late, great Adam Again. From their 1992 album Dig. Unfortunately this album—and every other Adam Again album—is out of print. You can find used copies on...

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Wednesday, August 18, 2021 entitled "The Ring Nebula from Hubble."

This wonderful image of God's creation brings to mid the poem 'ring and around the roses, pocket full of posies, ashes, ashes we all fall down' which was written during the Black Death and is an example of dark humor.

APOD Background
"Explanation: The Ring Nebula (M57), is more complicated than it appears through a small telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star. This composite image includes red light emitted by hydrogen as well as visible and infrared light. The Ring Nebula is an elongated planetary nebula, a type of nebula created when a Sun-like star evolves to throw off its outer atmosphere to become a white dwarf star. The Ring Nebula is about 2,500 light-years away toward the musical constellation Lyra.
