On the left, with grand spiral arms and bright yellow core is spiral galaxy M81, some 100,000 light-years across. On the right marked by red gas and dust clouds, is 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&#8217;s spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic 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. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap200515.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>These two galaxies are far far away, 12 million light-years distant toward the northern constellation of the Great Bear.
