Bright Spiral Galaxy M81

Explanation: One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful M81. This grand spiral galaxy can be found toward the northern constellation of the Great Bear(Ursa Major). This superbly detailed viewreveals M81's bright yellow nucleus, blue spiral arms, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane actually runs straight through the disk, to the left of the galactic center, contrary to M81's other prominentspiral features. The errant dust lane may be the lingering result of a close encounterbetween M81 and its smaller companion galaxy, M82. Scrutiny of variable stars inM81 has yielded one of the best determined distances for an external galaxy -- 11.8 million light-years.

As planned, the Cassini spacecraft impacted the upper atmosphere of Saturn on September 15, after a 13 year long exploration of the Saturnian System. With spacecraft thrusters firing until the end, its atmospheric entry followed an unprecedented series of 22 Grand Finale dives between Saturn and rings. Cassini's final signal took 83 minutes to reach planet Earth and the Deep Space Network antenna complex in Canberra Australia where loss of contact with the spacecraft was recorded at 11:55 UT. For the spacecraft, Saturn was bright and the Sun was overhead as it plowed into the gas giant planet's swirling cloud tops at about 70,000 miles (113,000 kilometers) per hour. But Cassini's final image shows the impact site hours earlier and still on the planet's night side, the cloud tops illuminated by ringlight, sunlight reflected from Saturn's rings.

thanks to +CHASING ORGASM. Roland J. Ruttledge for this post.
The 19th century discovery of the Bush Barrow Lozenge highlights the fact that there are still many unanswered questions regarding this awe-inspiring and perplexing site of Stonehenge.
