Default Negatively Charged Particles

The new article says the first negatively charged particle was found. Now, perhaps this is becase the most physics I've taken so far, as a 10th grader, is an electricity class, but aren't electrons negatively charged?

The article was about negatively charged ions. Although types of many (neutral) molecules and positively charged ions (molecules missing one or more electrons) have been found, this is the first finding of a negatively charged ion (a molecule with one or more extra electrons) in space.

Ah, thank you, that makes much more sense now.

Actually, I don't know what the article is specifically talking about, but an atom with a negative charge also counts as a negative ion. One very prominent example of a negative ion in space is therefore the substance that emits sunlight-- the negative hydrogen ion (although this is not a molecule).

So what are the implications of this finding?

Which new article (he asked with a dumb look on his face)?

Negatively charged ions are indeed nothing new. The are observed all over the planetary system. I, myself, have found Cl- in the pickup cloud around the moon Europa using Galileo magnetometer data.

Ah, I think I know the problem. I negelcted to make sure I didn't mix up the words particle and molecule. The first negatively charged molecule has been found, so says the article.
