It means this is classic journalistic ignorant hype of a fairly important discovery.
The title is misleading. DNA was NOT, repeat NOT, found on asteroids, meteors, or contaminating our foodstuffs. OK, that last one isn't true, but they really didn't find DNA in space.
What they found was adenine and guanine, two of the four nucleobases that form DNA. This is like finding a couple of bricks in my yard and hollering "hey everyone, there's a mansion buried in my back yard!"
The reason it's important is that adenine and guanine don't naturally occur on Earth. The question 'where did those building blocks come from?' has been floating around for decades. So has the answer "they came from meteorites," but only now has that answer been unquestionably confirmed.
Due to the nature of the study of abiogenesis, I sincerely doubt that there will ever be a single creationism-busting discovery. It will be a slow, gradual process, sort of like abiogenesis itself. And pretty much no matter what science discovers, creationists will never admit that their silly literal reading of genesis is wrong.
