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.

Astronomers observe a 'sunburst' from the early universe - in 12 copies

With the powerful eyes of the Hubble Space Telescope, an international team of astronomers observed straight into the bright and hot heart of a galaxy 11 billion years old in no less than 12 multiple, gravitationally lensed images. The finding casts light onto a crucial era in our universe?s history: the epoch of reionization.

Galactic fountains and carousels: order emerging from chaos

Astronomers have unveiled the results of a newly-completed, state of the art simulation of the evolution of galaxies. It allows researchers to study in detail how galaxies form, and how they have evolved since shortly after the Big Bang. For the first time, it reveals that the geometry of the cosmic gas flows around galaxies determines galaxies? structures, and vice versa.
