NGC 289: Swirl in the Southern Sky
About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bluish spiral arms. The extensive arms sweep well over 100 thousand light-years from the galaxy’s center. At the lower right in this sharp, telescopic galaxy portrait the main spiral arm seems to encounter a small, fuzzy elliptical companion galaxy interacting with enormous NGC 289. Of course the spiky stars are in the foreground of the scene. They lie within the Milky Way toward the southern constellation Sculptor. via NASA https://ift.tt/2GWVQXi

Memphis From Space
We honor the legacy of Dr. Martin Luther King Jr., who delivered the famous „I’ve been to the mountaintop“ speech in Memphis, Tennessee fifty years ago, the day before he was assassinated on April 4, 1968. This image taken from the International Space Station shows a detailed view of the city of Memphis from low-Earth orbit. via NASA https://ift.tt/2q7bgyo
Intrepid Crater on Mars from Opportunity
The robotic rover Opportunity sometimes passes small craters on Mars. Pictured here in 2010 is Intrepid Crater, a 20-meter across impact basin slightly larger than Nereus Crater that Opportunity had chanced across previously. The featured image is in approximately true color but horizontally compressed to accommodate a wide angle panorama. Intrepid Crater was named after the lunar module Intrepid that carried Apollo 12 astronauts to Earth’s Moon 49 years ago. Beyond Intrepid Crater and past long patches of rusty Martian desert lie peaks from the rim of large Endeavour Crater, visible on the horizon. The Opportunity rover continues to explore Mars, recently surpassing 5,000 Martian days on the red planet. via NASA https://ift.tt/2GUEQ44

The Milky Way over the Seven Strong Men Rock Formations
You may have heard of the Seven Sisters in the sky, but have you heard about the Seven Strong Men on the ground? Located just west of the Ural Mountains, the unusual Manpupuner rock formations are one of the Seven Wonders of Russia. How these ancient 40-meter high pillars formed is yet unknown. The persistent photographer of this featured image battled rough terrain and uncooperative weather to capture these rugged stone towers in winter at night, being finally successful in February of 2014. Utilizing the camera’s time delay feature, the photographer holds a flashlight in the foreground near one of the snow-covered pillars. High above, millions of stars shine down, while the band of our Milky Way Galaxy crosses diagonally down from the upper left. via NASA https://ift.tt/2q0stJ0
