Good afternoon, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Jets from Unusual Galaxy Centaurus A." Active galaxies are galaxies that have a small core of emission embedded at the center of an otherwise typical galaxy. This core is typically highly variable and very bright compared to the rest of the galaxy. What can be emitted from the galactic core? As shown in today's image, jets of super-hot ionized plasma are ejected along the axis of rotation of a central massive black hole. These jets are detectable in the infrared, radio, UV, microwave, and X-ray regions of the electromagnetic spectrum.
Only 11 million light-years away, Centaurus A is the closest active galaxy to planet Earth. Spanning over 60,000 light-years, the peculiar elliptical galaxy also known as NGC 5128, In today's image, emitted X-ray light is depicted in blue, while microwave light is colored orange. The jets emerging from Cen A are over 1 million light years long. After clearing the galaxy, however, the jets inflate large radio bubbles that likely glow for millions of years.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) is titled "Jets from Unusual Galaxy Centaurus A."

Thank you my friend Sgt (Join to see) for mentioning me.
APOD Background
"Explanation: The jets emanating from Centaurus A are over a million light years long. These jets of streaming plasma, expelled by a giant black hole in the center of this spiral galaxy, light up this composite image of Cen A. Exactly how the central black hole expels infalling matter remains unknown. After clearing the galaxy, however, the jets inflate large radio bubbles that likely glow for millions of years. If energized by a passing gas cloud, the radio bubbles can even light up again after billions of years. X-ray light is depicted in the featured composite image in blue, while microwave light is colored orange. The base of the jet in radio light shows details of the innermost light year of the central jet.
