Alien Particles

Scientists have discovered particles that DID NOT originate in our solar system. They did not come from our sun or our planets. They came from somewhere else in the galaxy,
It doesn’t sound like such a great discovery, until you consider that these particles - hydrogen, oxygen, and neon - are the fundamental building blocks for planets, stars, and lifeforms like human beings. To know that these elements exist outside our own solar system is incredible. There may be another Earth-like planet out there after all.
