Does it look like black oil?
Nevermind, I think that's an alien virus -not alien bacteria.
I read the article, and while it sounds exciting, there's a big, giant hole in the story:
Some of the samples were captured covered with cosmic dust, adding further credence to the idea that they have originated from space.
...
"The particles are very clean," added Prof Wainwright. "They don't have any dust attached to them, which again suggests they're not coming to earth. Similarly, cosmic dust isn't stuck to them, so we think they came from an aquatic environment, and the most obvious aquatic environment in space is a comet.
Uh, Ken, we ARE alien bacteria.
Yup. As Allan Sandage so beautifully put it, "Every one of our chemical elements was once inside a star. The same star. You and I are brothers. We came from the same supernova."
