This was a big week for space! Astronomers found both the oldest star we've ever seen, and also the youngest galaxy. Trace is here to tell you what these two findings can teach us about the origins of everything!
Theoretical physicists may have stumbled onto a solution to the black hole "information paradox" -- what if a black hole's singularity isn't an infinitely dense point in space-time? Continue reading →
Records for furthest, biggest and brightest are always being broken in astronomy, but one of the more intriguing records has just been smashed. Continue reading →
