The Cosmos with NGC 474
What’s happening to galaxy NGC 474? The multiple layers of emission appear strangely complex and unexpected given the relatively featureless appearance of the elliptical galaxy in less deep images. The cause of the shells is currently unknown, but possibly tidal tails related to debris left over from absorbing numerous small galaxies in the past billion years. Alternatively the shells may be like ripples in a pond, where the ongoing collision with the spiral galaxy just above NGC 474 is causing density waves to ripple through the galactic giant. Regardless of the actual cause, the featured image dramatically highlights the increasing consensus that at least some elliptical galaxies have formed in the recent past, and that the outer halos of most large galaxies are not really smooth but have complexities induced by frequent interactions with — and accretions of —smaller nearby galaxies. The halo of our own Milky Way Galaxy is one example of such unexpected complexity. NGC 474 spans about 250,000 light years and lies about 100 million light years distant toward the constellation of the Fish (Pisces).
Natalie Cole Day
Natalie Maria Cole (February 6, 1950 – December 31, 2015) was an American singer, voice actress, songwriter, and actress. The daughter of Nat King Cole, she rose to musical success in the mid-1970s as an R&B artist with the hits “This Will Be“, “Inseparable” (1975), and “Our Love” (1977). Cole re-emerged as a pop artist with the 1987 album Everlasting and her cover of Bruce Springsteen‘s “Pink Cadillac“. In the 1990s, she re-recorded standards by her father, resulting in her biggest success, Unforgettable… with Love, which sold over seven million copies and also won Cole seven Grammy Awards. She sold over 30 million records worldwide. On December 31, 2015, Cole died at the age of 65 at Cedars-Sinai Medical Center in Los Angeles, California, due to congestive heart failure.

The Cosmos with NGC 7635
It’s the bubble versus the cloud. NGC 7635, the Bubble Nebula, is being pushed out by the stellar wind of massive star BD+602522, visible in blue toward the right, inside the nebula. Next door, though, lives a giant molecular cloud, visible to the far right in red. At this place in space, an irresistible force meets an immovable object in an interesting way. The cloud is able to contain the expansion of the bubble gas, but gets blasted by the hot radiation from the bubble‘s central star. The radiation heats up dense regions of the molecular cloud causing it to glow. The Bubble Nebula, pictured here is about 10 light-years across and part of a muchlarger complex of stars and shells. The Bubble Nebula can be seen with a small telescope towards the constellation of the Queen of Aethiopia (Cassiopeia).
