When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
Planetary scientist Konstantin Batygin discusses the elusive Planet Nine and how he fell into astrophysics whilst waiting for his rock band to become the next Metallica.
Characterizing planets through direct imaging is no easy task! But today’s authors offer a work-around formula, which estimates the crucial parameter of planetary mass from protoplanetary disk observations. In this astrobite, we discuss ‘The Theory’ and ‘The Practice’ of their cool equation.
Bright surface features ring Titan’s north polar lakes and trace out dry lake beds. Could these same features in the equatorial desert regions indicate that what is now desert was once covered in liquid?
In this bite we dig into the details of the recent discovery of 7 habitable zone planets orbiting TRAPPIST-1.
Europa might be the smallest of the Galilean moons orbiting Jupiter, but it is potentially one of the most exciting candidates for extra-terrestrial life in our diverse Solar System. This bite covers a tiny portion of the Europa Lander Report recently published by NASA.
