[Guest post] Inviting dimmer cousins to the party
Are fainter galaxies really different than brighter ones? This study reveals that, despite being dimmer, low surface brightness galaxies obey the same fundamental laws of galaxy formation, offering new clues about how galaxies and dark matter halos evolve.
Guide to the (Lomb-Scargle) periodogram
Today’s bite breaks down the Lomb–Scargle periodogram, a popular tool astronomers use to hunt for periodic signals, and explains how sometimes it fools us into seeing patterns that aren’t really there.
What if Mars were a Stranger (Thing)?
If our familiar red neighbor were a stranger light-years away, would we even know what we were looking at?
