Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "The Andromeda Galaxy in Ultraviolet." To capture the full grandeur of Andromeda (M31), researchers assembled 11 different exposures from the Galactic Evolution Explorer (GALEX) spacecraft into this single composite that captures the nebula's 230,000 light year expanse. The ring structure pops out when M31 is examined in only ultraviolet. A similar structure emerges when the same analysis is done using only infrared. This view is two-color composite, where blue represents far-ultraviolet light, and orange is near-ultraviolet light.

Weyes Blood - Andromeda (Live on KEXP)

http://KEXP.ORG presents Weyes Blood performing "Andromeda" live in the KEXP studio. Recorded May 17, 2019.Host: Abbie GobeliAudio Engineers: Ryan McHugh & K...

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Sunday, July 18, 2021 entitled "The Andromeda Galaxy in Ultraviolet."

I am listening to Stan Getz from the 1950s and 1960's this afternoon.

I hope and pray that each of you are enjoying a peaceful and joyful Sunday.

APOD background
"Explanation: What does the Andromeda galaxy look like in ultraviolet light? Young blue stars circling the galactic center dominate. A mere 2.5 million light-years away, the Andromeda Galaxy, also known as M31, really is just next door as large galaxies go. Spanning about 230,000 light-years, it took 11 different image fields from NASA's Galaxy Evolution Explorer (GALEX) satellite telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light in 2003. While its spiral arms stand out in visible light images, Andromeda's arms look more like rings in ultraviolet. The rings are sites of intense star formation and have been interpreted as evidence that Andromeda collided with its smaller neighboring elliptical galaxy M32 more than 200 million years ago. The Andromeda galaxy and our own comparable Milky Way galaxy are the most massive members of the Local Group of galaxies and are projected to collide in several billion years -- perhaps around the time that our Sun's atmosphere will expand to engulf the Earth."
