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.
High-energy particles make radio signals in ice
Ultrahigh-energy neutrinos can be our gateway to studying some of the Universe’s most energetic but least understood phenomena. Today’s paper presents a proof-of-concept for a new, promising way to detect these ultrahigh-energy particles.
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?
