Nothing of me is original. I am the combined effort of everybody I've ever known.(CP)
I happen to be Alice,
I make a great deal of gifs and I like to rant about the things I love about science (which is most everything)... I have always been looking up, to the cosmos. I am claustrophobic without the stars and my favorite galaxy Andromeda.
I enjoy educating other humans about the universe and the origins of their very atoms. I write frequently and am trying my hand at drawing.
I post a lot of things, check my links (<-click) for some of them, I try to update that section on a more consistent basis.
What causes the surrounding shells in peculiar galaxy Cen A? In 2002 a fascinating image of peculiar galaxy Centaurus A was released, processed to highlight a faint blue arc indicating an ongoing collision with a smaller galaxy. Another interesting feature of Cen A, however, is the surrounding system of shells, better visible here in this recently released wider pan from the four meter Blanco telescope at Cerro Tololo Inter-American Observatory. Faint shells around galaxies are not unusual and considered by themselves as evidence of a previous galaxy merger, analogous to water ripples on a pond. An unexpected attribute of these shells is the abundance of gas, which should become separated from existing stars during the collision.
