Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "The Galaxy, the Jet, and a Famous Black Hole." Messier 87 (aka M87 and Virgo A) is located 55 million light years from Earth in the constellation Virgo. It is one of the 'brightest' (in terms of the overall electromagnetic spectrum) sources in the sky and a popular target for both amateur and professional astronomers. The black hole at the center of M87 was first imaged by the Event Horizon Telescope (EHT) in 2019.
Today's composite image of M87 features the 2019 depiction of the black hole in the lower right insert. Above this are two data sets from the Spitzer Space Telescope. The left image is M87 itself cast in blue hues. On the right is visual representation of the relativistic jets that extend more than 5,000 light years from the center of M87. What we see here are the shock waves of these jets detected at infrared and radio wavelengths. The right most jet extends along our line of sight to M87 (the increased brightness is due to its movement towards us). The left most jet extends behind the galaxy, but we can still detect the shock wave that it produces.

Soundgarden - Black Hole Sun (Live From The Artists Den)

Belated thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Thursday, April 15, 2021 entitled "The Galaxy, the Jet, and a Famous Black Hole."
Yesterday I was focused on taking care of my darling wife.
The LORD reminds us that eye has not seen nor mind imagines the wonders that God has prepared for HIS own.
Another wonderful artist's conception collaborative image :-)

APOD background
"Explanation: Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is the large galaxy rendered in blue hues in this infrared image from the Spitzer Space telescope. Though M87 appears mostly featureless and cloud-like, the Spitzer image does record details of relativistic jets blasting from the galaxy's central region. Shown in the inset at top right, the jets themselves span thousands of light-years. The brighter jet seen on the right is approaching and close to our line of sight. Opposite, the shock created by the otherwise unseen receding jet lights up a fainter arc of material. Inset at bottom right, the historic black hole image is shown in context, at the center of giant galaxy and relativistic jets. Completely unresolved in the Spitzer image, the supermassive black hole surrounded by infalling material is the source of enormous energy driving the relativistic jets from the center of active galaxy M87."

Chris Cornell - Black Hole Sun Acoustic
April 22 on CBS in a segment called "Saturday sessions". Idk why they took it down but here it is. rip chris.
The LORD reminds us that eye has not seen nor mind imagines the wonders that God has prepared for HIS own.
Here is the songwriter Chris Cornell performing an acoustic version of his class song

Maj William W. 'Bill' Price
A good morning to you Alan K., and a fair first thought. Kudos to the first band that uses this as a promo poster (I guess there are no longer any "album covers").
