Three sisters age 92, 94 and 96 live in a house together. One night the 96 year old draws a bath, puts her foot in and pauses. She yells down the stairs, “Was I getting in or out of the bath?” The 94 year old yells back, “I don’t know, I’ll come up and see.” She starts up the stairs and pauses, then she yells, “Was I going up the stairs or coming down?”
The 92 year old was sitting at the kitchen table having tea listening to her sisters. She shakes her head and says, “I sure hope I never get that forgetful.” She knocks on wood for good measure. She then yells, “I’ll come up and help both of you as soon as I see who’s at the door.”

Spiral Galaxy NGC 1512: Wide Field Image Credit & Copyright: Daniel Stern
Explanation: Most galaxies don’t have any rings — why does this galaxy have three? To begin, a ring that’s near NGC 1512‘s center — and so hard to see here — is the nuclear ring which glows brightly with recently formed stars. Next out is a ring of stars and dust appearing both red and blue, called, counter-intuitively, the inner ring. This inner ring connects ends of a diffuse central bar of stars that runs horizontally across the galaxy. Farthest out in this wide field image is a ragged structure that might be considered an outer ring. This outer ring appears spiral-like and is dotted with clusters of bright blue stars. All these ring structures are thought to be affected by NGC 1512‘s own gravitational asymmetries in a drawn-out process called secularevolution. The featured image was captured last month from a telescope at Deep Sky Chile in Chile.
