Good Red Friday morning, Rallypoint, and welcome to the January 20th edition of Astronomy Picture of the Day (APOD): "Galaxy Wars: M81 and M82." Both M81 (right) and M82 (left) lie some 12 million light years away towards the constellation Ursa Major (The Big Dipper). Researchers believe the two have been locked in a gravitational tango for over 1 billion years. Based on observational data, the last "close encounter" was 100 million years ago and resulted in the sculpted arms in M81 and vigorous star formation in M82. Eventually, the two will merge and only one galaxy will remain.
M81 (aka Bode's Galaxy) was originally discovered by Johann Elert Bode on December 31, 1774. Bode also discovered M82 in 1774. Charles Messier's colleague Pierre Méchain re-identified both in 1779, and they were subsequently entered into the 1781 edition of Messier's Catalogue des Nébuleuses et des Amas d'Étoiles (Catalogue of Nebulae and Star Clusters).

Thank you my space-exploration advocate friend and brother-in-Christ Maj William W. 'Bill' Price for posting the Saturday, January 20, 2023 Astronomy Picture of the Day (APOD): Galaxy Wars: M81 and M82;

Explanation: The two dominant galaxies near center are far far away, 12 million light-years distant toward the northern constellation of the Great Bear. On the right, with grand spiral arms and bright yellow core is spiral galaxy M81. Also known as Bode's galaxy, M81 spans some 100,000 light-years. On the left is cigar-shaped irregular galaxy M82. The pair have been locked in gravitational combat for a billion years. Gravity from each galaxy has profoundly affected the other during a series of cosmic close encounters. Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic that the galaxy glows in X-rays. In the next few billion years, their continuing gravitational encounters will result in a merger, and a single galaxy will remain. This extragalactic scenario also includes other members of the interacting M81 galaxy group with NGC 3077 below and right of the large spiral, and NGC 2976 at upper right in the frame. Captured under dark night skies in the Austrian Alps, the foreground of the wide-field image is filled with integrated flux nebulae. Those faint, dusty interstellar clouds reflect starlight above the plane of our own Milky Way galaxy.

Prayer Warrior's Heart - The McFall's - Madonna McFall Massey
Prayer Warrior's Heart - The McFall's - Madonna McFall Massey - This has been my favorite of all the great songs recorded by the McFalls since I first heard...
Image: Prayer Warrior Ephesians 6:10-18 ESV ''Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. 'Therefore, take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and, as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication.'"
