A team of astronomers proposes a new method of using Webb to determine whether a rocky exoplanet has an atmosphere. The technique, which involves measuring the planet's temperature as it passes behind its star and then comes back into view, is significantly faster than more traditional methods of atmospheric detection like transmission spectroscopy.

Exoplanet axis study boosts hopes of complex life, just not next door

Astrophysicists modeled a theoretical twin of Earth into other star systems called binary systems because they have two stars. They concluded that 87% of exo-Earths one might find in binary systems should have axis tilts similarly steady to Earth's, an important ingredient for climate stability that favors the evolution of complex life.

Nearly extreme black holes which attempt to 'regrow hair' become bald again

Black holes 'have no hair': no attributes that can be used to tell them apart. Extreme black holes can have an additional property, permanent hair that is made of a massless scalar field. Nearly extreme black holes have hair that is a transient phenomenon: nearly extreme black holes that attempt to regrow hair will lose it and become bald again.
