Which exoplanets are the most worthwhile to search for life on? Today’s paper explores the “continuous habitable zone” as an important criterion for atmospheric characterization target selection.
K2-290A’s two close-in planets’ orbits are retrograde relative to the star’s rotation. Today’s paper explores how dynamical interactions in the triple star system may have caused this misalignment.
Antisatellite weapon tests launch space debris into low Earth orbit (LEO), threatening other satellites. Today’s paper explores how commercial satcons rapidly populating LEO exacerbate this danger.
This Summer I was part of the organizing committee for an online conference for early-career SETI researchers. Here’s what the process was like.
Is there a ninth planet in the solar system? Today’s paper examines the orbital clustering of some Kuiper belt objects and where the planet causing these gravitational perturbations may be found.
