Next time you're sweating the small stuff, try running these numbers in your head for dramatic renewal of perspective: There are at least 100 billion stars in our galaxy, the Milky Way, and at least two trillion other galaxies out there. And those are just the ones we can see with our telescopes. So far. Perspective restored!
But how do those galaxies form in the first place? Well, we know some things for sure, and we have a lot of good theories past that. One interesting update: Astronomers recently witnessed stars forming spontaneously in the cold gases of a baby galaxy about 10 billion light years away. Cosmologists weren't expecting it, and it suggests galactic formation may take many forms. Dedicated stargazer Julian Huguet has the details in today's DNews dispatch.
